The data format that we use in the electronic (DVD) part of the atlas allows one to quantitatively access information for oceanographic variables as well as plankton, benthos, fish, sea birds, and marine mammals. The data are divided into one-degree squares with monthly climatic characteristics calculated for every square, which were used to plot monthly climatological charts of temperature and salinity. Access to the primary data is carried out through a graphical interface presented in the shape of a geographical chart. The Atlas also includes, in electronic format, selected copies of rare books and articles about the history of Arctic exploration and climate studies as well as photos and drawings, which provide information about the people and nature of the northern polar latitudes throughout the past two centuries. 32 1. INTRODUCTION The natural resources of the Barents, Kara, Laptev, and White Seas are rich and diverse. For many decades, they have supported an enormous and lucrative fishing industry, and today this region continues to be a zone of intensive navigation by providing cargo transportation between the cities of Europe, Asia, and the Far East. In addition, the petroleum sector is actively exploring potential oil and gas fields for development. Consequently, the exploitation of natural resources in this region makes it necessary to study a broad range of environmental issues, among which is a priority to better understand the impact on these resources due to changes in climate. This is even more crucial since the Arctic is inhabited by a variety of human populations, many of whom derive their livelihood from the resources in the Arctic, and it boasts terrestrial and marine ecosystems that do not exist anywhere else. Climate studies of the Arctic have resulted in a large number of publications that describe various changes taking place within this region and which document and explain sources of variability in the Arctic climate system. However, because this has been an area of chronically poor data coverage, the ability to quantify high-latitude climate variability on interannual to inter-decadal temporal scales has been limited. Thus, this product will provide a more comprehensive series of oceanographic and biological observations in the Barents, White, Kara, and Laptev Seas, which can be used for long-term global change monitoring. 33 2. HISTORY OF OCEANOGRAPHIC INVESTIGATIONS IN THE ARCTIC Systematic studies of the Barents, White, Kara, and Laptev Seas started in the second half of the 19th century. These studies were initiated to search for a fast and reliable way to deliver cargo between the ports of Europe, Russia, Asia, and America. Germany, Norway, France, the Netherlands, England, Russia, USA, and other countries sent their ships to the Arctic for scientific and commercial objectives. It is beyond the scope of this discussion to provide a comprehensive review of Arctic exploration, and the reader is directed to the “Electronic Library,” which provides partial and full texts of books that go into much more detail. However, it is appropriate to briefly consider the basic events in the history of studies of these seas. The first half of the 19th century was a period of intensive trade of marine and terrestrial animals found near Spitsbergen and the western part of the Kara Sea. Hundreds of ships from different countries took part in this trade. It was aboard an English whaleboat in April 19, 1810, that the first oceanographic measurements were made by William Scoresby at 76o16’ N, 9o00’ E in the Arctic, both at the surface and at depth. This data is included in the1871 publication by Piterman et al., the full text of which appears in the “Electronic Library” section. The same publication contains meteorological and ocean-surface temperature data collected during the first German Arctic expedition (1868-1970) in the northeastern part of the Norwegian Sea and northwestern part of the Barents Sea. At present, there is a considerable amount of sea-surface temperature and meteorological data for the Kara and Barents Seas covering the period of 1867-1912. This is the result of carefully prepared ship logs by the captains of Norwegian commercial ships which utilized the Northeast Passage. The section for “Database/Cruises” on the DVD contains data from 168 Norwegian cruises. Efforts to pass through the Northeast Passage and establish this as a viable trade route began in the 1590s with expeditions by Willem Barents. The next attempt was not until 173443, when Vitus Bering explored the Siberian coast as part of the Great Nordic Expedition. Julius Von Payer, in an Austrian-Hungarian expedition in 1872-74, also attempted to sail through the Northeast Passage, but this expedition ended at Novaya Zemlya when ice trapped his ship. In 1875-76, the Swedish researcher, A.E. Nordenskiöld, aboard the ships Pröven and Eemer, was the first to sail from Europe to the mouth of the Ob River in order to prove the possibility of cargo transportation from Europe to Siberia. In 1877, the first Russian cargo cruiser, Utrennyaya Zarya, sailed from the Yenisey River to St. Petersburg via the Kara and Barents Seas. In 1878-79, with better preparations, Nordenskiöld left aboard the Vega and successfully traversed across the Barents Sea to the Pacific via the Kara Sea. During the cruises in the Barents and Kara Seas on the Pröven, Eemer, and Vega, meteorological observations and oceanographic measurements at both the surface of the water and at depth were conducted. With the discovery of the Northeast Passage in the late 1870s and until 1936, regular commercial transport between Europe and across the Barents and Kara Seas took place. This is described in more detail by Khmiznikov in 1937, available in the “Electronic Library” section of 34 the DVD. During this period, forecasts of ice conditions for the Barents and Kara Seas were of critical importance. The cost of ship and cargo insurance reflects the realities of forecasting ice conditions in the Barents and Kara Seas: in 1914, insurance costs were 6%-8% of the total expeditionary budget; in 1929 – 0.8% - 2.25% (Wieze, 1934; full text of this book is available in the “Electronic Library” section of the DVD). In 1879, Britain and The Netherlands explored the Barents and Kara Seas with expeditions conducted aboard the Isbjörn and the W. Barents, respectively, the latter performing meteorological observations and water-temperature measurements. From 1880-84, The Netherlands again used the W. Barents to conduct hydrological surveys over a considerable part of the Barents Sea. In 1882, the First International Polar Year (IPY I) commenced. It was organized at the initiative of Karl Weyprecht, the leader of the Austro-Hungarian expedition aboard the Tegetthoff to study Franz Josef Land in 1872-1874. The goal of IPY I was to organize an Arctic network of polar stations to conduct meteorological and magnetic observations on a regular basis. Twelve countries took part in IPY I, and they established 15 meteorological stations. Russia established meteorological stations at Malye Karmakuly, on Novaya Zemlya, and Sagatyr, located at the mouth of the Lena River (see the “Photo Gallery” section). In Siberia, there was a shortage of meteorological stations, so The Netherlands and Denmark established stations on Dickson Island and at Cape Chelyuskin (on the Taimyr Peninsula), respectively. The Netherlands sent the ship, Varna, to establish a meteorological station on Dickson Island. During the entire month of August 1882, the Varna tried to penetrate the ice-covered Kara Sea. By the end of August 1882, she became trapped by ice in the Kara Sea, and while she drifted, deep-sea temperature and density measurements were performed (Snellen, 1910; see the full text of this book in the “Electronic Library” section). While the Varna was drifting in the Kara Sea, the Danish steamship, Dijmphna, was sent to build a meteorological station on the Taimyr Peninsula. Unfortunately, the Dijmphna also became entrapped by ice, and it drifted together with the Varna (see “Photo Gallery”). The Varna sank in the Barents Sea on 24 July 1883, but not before the crew was able to escape to the nearby Dijmphna. Soon after, the crew of the Varna left the Dijmphna and headed out on the ice to make their way to Novaya Zemlya, taking along three sleds and four small boats. Near Yugorsky Shar, the crew met the ship, Nordenskiöld, which delivered them to Norway. The Dijmphna was liberated from the ice in the middle of September 1883; and in October, she arrived back in Norway. In 1893, the Fram expedition, led by F. Nansen, conducted meteorological and hydrological observations in the Barents and Kara Seas. In the same year, N. Knippovitch conducted a series of hydrological observations in the Barents Sea. From 1898-1914, motivated to further explore the North, Russia organized two large expeditions in the Barents, White, and Kara Seas. These expeditions, aboard the Andrey Pervozvanny, Pakhtusov, and Pomor, collected meteorological and hydrobiological data. In 1898, the Russian icebreaker, Yermak, set forth into the Barents Sea with the goal of reaching the North Pole. Although the Yermak was unable to fulfill this mission, it proved that 35 icebreakers were able to overcome ice-covered seas that are inaccessible to regular ships. During the Yermak voyage, meteorological and hydrobiological data were collected (Makarov, 1901). In 1905 and 1907, a French-sponsored expedition on the Danish ship, Belgica, engaged in hydrological and hydrobiological studies in the Barents and Kara Seas. In the “Electronic Library” section, there is a full report of the 1907 expedition, including the meteorological data and sea-surface temperature measurements. The Russian polar researcher, V. Rusanov, set out in 1912 on the small boat, Hercules, with the intention of studying the Kara Sea. He began his journey from Archangel on 12 August 1912, but he disappeared and his fortune remains unknown. The ship, Eclipse, was sent to search for Rusanov’s expedition. During its passage from the Barents to the Kara Sea, the Eclipse expedition carried out meteorological observations and sea-surface temperature measurements (Trzemestskiy, 1917). The full text of the report on this expedition is in the “Electronic Library” section. Studies of the White Sea for navigation purposes started in the 17th century. The first charts containing data on ice conditions were published by the Russian Navy in the mid-18th century. In 1881, a biological station was established on the Solovetsky Islands, and regular hydrobiological studies commenced for this region. In 1899, the station moved from the Solovetsky Islands to the Yekaterininsky Harbor in the Kola Bay, located in the southern part of the Barents Sea. At that time, the station officially became the Murmansk Marine Biological Station (MMBI). In the “Electronic Library” section, the full text of Deryugin’s description of hydrobiological studies (Deryugin, 1906) conducted by the MMBI during 1899-1905 is available. In the mid-1930s, a system of measuring along standard transects in the White Sea was adopted. Even today, these transects are used to conduct hydrological surveys; during World War II, there was no abatement in the hydrological studies along these transects. On the DVD, there are temperature and salinity profiles for the period 1941-1945. During the 1950s, the Zoological Institute of the Russian Academy of Sciences established a biological station in the Kandalaksha Bay in the White Sea. Since 1961 and up to the present, measurements are taken every ten days at one location. These include water temperature and salinity at 0, 5, 10, 15, 25, 50, and 65 m. In 1963, in addition to temperature and salinity measurements, observations of zooplankton began, which have also been collected every ten days. This data has been used to document marine environmental effects on zooplankton development in this region (Berger et al., 2003). The Laptev Sea was difficult to reach due to its distance from both the Atlantic and Pacific Oceans. However, Vitus Bering, Hariton Laptev, Dmitry Ovtsin, and others were among the first the first to reach this area during the Great North Expedition that was conducted from 1734-42, during which the entire Siberian coast was surveyed and documented. In the 1820s, the Ust-Yana expedition, led by Pyotr Anzhu, succeeded in conducting a hydrographic survey of the Laptev Sea coast between the Olenyok and Indigirka rivers, and he also mapped the New Siberian Islands. 36 In 1900, the Russian Academy of Sciences equipped Eduard Toll for an expedition aboard the ship, Zarya, to study the Novosibirsk Islands in the Laptev Sea. This expedition collected hydrobiological data that has been partially published. In the early 20th century, the Russian Government began to study the problem of promoting regular voyages from the Barents Sea to the Pacific Ocean. Two icebreakers, Taimyr and Vaigach, were built for this purpose. During the period 1911-1915, these icebreakers made several voyages from Vladivostok to the west via the Bering Strait during which a wide spectrum of oceanographic and hydrobiological studies was conducted (Transehe, 1925. In the section, “Bathymetry” on the DVD, there is a chart of the Taimyr and Vaigach voyages). Most of the data from these expeditions is not yet published. In 1918, although he was unable to reach the North Pole, Roald Amundsen did succeed in sailing as far east as Cape Chelyuskin, on the Taimyr Peninsula, where he over wintered. The next year, Amundsen continued his journey eastward and became only the second person to sail through the Northeast Passage. In the 1920s, efforts to study the northern regions of the European and Asian parts of the Soviet Union began. For this purpose, the Government of the Soviet Union provided significant funds. A portion of these funds was used to build a network of meteorological stations along the ship route, from the Atlantic Ocean to America and Asia via the Bering Strait. Formerly known as the Northeast Passage, this route became identified as the Northern Sea Route. In the 1920s, building commenced on icebreakers and ice-class transport ships that would be able to penetrate the ice-encrusted seas. At the same time the number of scientific expeditions to the seas of the eastern sector of the Arctic increased. During the Second International Polar Year, 1932-33, the Soviet Union organized over ten expeditions that conducted studies from the Bering Sea to the Greenland Sea. During these expeditions, substantial amounts of meteorological, oceanographic, and hydrobiological data were collected. Part of this material is included in this database as well as contained in publications by Markhayev et al., 2003, Lappo et al., 2003. After World War II, a new stage began in studying the Arctic seas due to an increased interest in exploring fishery resources of the Barents and White Seas, oil and gas mining in the Barents and Kara Seas, and providing safe navigation along the Northern Sea Route. In this period, a variety of platforms were utilized to study the Arctic seas: scientific stations on floating ice fields (Romanov, et.al., 1997), airplanes (Konstantinov et al., 2000), and atomic icebreakers (Matishov et al., 2000). The oceanographic and hydrobiological data collected up to the present time can be used to solve a wide range of problems in various areas of oceanography, marine biology. The database presented here contains 433,179 stations for the period of 1810 to 2001. All the primary data is on a DVD disk. 37 3. BATHYMETRY AND SEA-BOTTOM TOPOGRAPHY OF THE BARENTS-KARA SHELF During the 20th and 21st centuries, great success was achieved in studying complicated events and phenomena that determine the nature of seas and oceans as well as of glacial and periglacial shelves (Matishov, 1980). The dynamics, thermohaline structure, and hydrochemical cycle of polar sea waters are the function of climate, ice conditions, and other natural factors. Of special importance is the shelf topography. When traveling along the troughs, Atlantic and Arctic waters transport and redistribute biogenous, radioactive, and other substances (Matishov, 1984; Zenkevich 1963; Bogorov, 1967; Nikiforov, Shpaiher, 1980; Matishov et al., 1982). Fridtjof Nansen (1904) was the first to start geomorphologic and oceanographic studies of the Arctic Ocean shelf. P.S. Vinogradov, V.M. Litvin, V.D. Rvachev, G.G. Matishov, and B.S. Senin (Vinogradov, 1964, 1979; Litvin, 1973, 1979; Matishov, 1987; Matishov, Rvachev 1983) contributed much to the bathymetric cartography of the Arctic Ocean bottom. A series of bathymetric charts for the North Atlantic Ocean, Norwegian-Greenland basin, and the Barents, White, and Kara Seas were compiled during the 1950s to 1990s (Matishov, 1984, 1987, 1995). The charts are based on bathymetric plane tables and 200,000-scale Mercator projections, which were compiled using detailed sea-bottom echo-sounding profiles (see “Bathymetry” section on DVD). These charts are mainly from MMBI and the Knipovich Polar Research Institute of Marine Fisheries and Oceanography (PINRO). When compiling bathymetric charts for the Barents-Kara shelf and Franz-Josef Land, the data from sea-bottom seismic profiling was also used. The Barents Sea bottom has a very diverse topography. The average shelf depth is about 250 m; with a maximum depth ranging 400-500 m. The outer edge of the shelf in the north and west of the Barents Sea stretches along the banks at 200- to 350-meter depths and along the troughs at 400- to 550-meter depths (Atlas, 1967, 1980; Dobrovolsky, Zologin, 1982; Suhovey, 1986). Shallow areas of the shelf (less than 100 m depth) are mainly found in the southeastern part of the Sea, on the narrow coastal strip of the archipelagos, Novaya Zemlya and Spitsbergen, and on the Medvezhinsko-Nadezhdinsk upland. In other regions, only small sections of the seabottom – the tops of some banks and ridges – are at depths less than 80-100 m. The deep troughs and vast banks exert control, to a large extent, over vertical and horizontal water circulation. Among all the shelf-topography forms made by continental ice, typical forms are fjords, edge and cross troughs, and sea-bottom edge glacial formations. Detailed bathymetric charts clearly show a direct connection between the underwater valleys of the coastal shelf to the hydrological network of the continent. Underwater fjords are morphologically dense networks of trough-shaped valleys, which have cut up the rocky sea-bottom over tens and hundreds of meters. Such fjord systems as Porsangen, Lakse, Tana, and Varanger near the northern Norwegian coast are examples of comparatively wide (5-20 km) and deep (150-400 m) underwater fjords. These valleys rectilinearly stretch for 20-100 km from the shore towards the sea. The edge troughs stretch along the coastal shelf of northern Norway, Spitsbergen, Novaya Zemlya, and Franz Josef Land, representing a system of narrow (5-16 km), shallow (100-200 m), successively located valleys and wide (64 km) troughs (Voronin, East-Novaya Zemlya, South- Novaya Zemlya and North-Novaya Zemlya) with depths of 250-450 m. 38 It is natural that almost along the entire length of the polar shelf, sub-parallel lateral troughs separate uplands and plateaus from each other. In particular, in the southeast Barents Sea, there is a network of troughs separating Moller Bay and the Gusinoye, as well as North- and South-Kanin Banks. They represent large valleys dissecting stratified and basalt shelf plains. The deep (300-500 m) troughs, Medvezhinsky, Finmarken, and Zuidkapp, as well as the Central depression, stretch for several hundreds of kilometers reaching a width of 100-200 km. On the slopes of the Central and Novaya-Zemlya upland, trade valleys are connected to each other via little breaks and cracks. The Perseus upland in the north of the Barents Sea is the most dissected. It consists of small, shallow (50-160 m) plateaus-horsts separated by graben-shaped troughs with incision depths of 100-200 m. On the surface of the Barents Sea shelf, there are large uplifts: Murman, Central, Nordkapp, Medvezhinsk-Nadezhdinsk. They serve as main water divides for all large currents and water mass circulation. The height of these flat-slopey sea-bottom uplifts is comparatively large, sometimes reaching 200-400 m. Their length can be as much as 2-5 hundreds of kilometers and width – 100-200 km. Usually, on terraces predetermined by breaks, flat slopes of these uplifts can reach a 2-4o steepness. The high-latitude (80-82o N) archipelago, Franz Josef Land, represents a complicated system of large (more than 1000 km2) and small basalt islands with deep-water straits (400-650 m) between them. All large islands are covered with glaciers in the shape of sheets or flat domes like Jackson dome (576 m) on Hooker Island, Vetrenny dome (509 m) on Gram-Bell Island, and Tindal dome (519 m) on Wilczek Land. Above the glaciers, there are rocky peaks like in the Wullerstorf Mountains (670 m) on the Wilczek Land Island. The complicated system of bathymetric edge and cross troughs of the Barents Sea shelf allows for the flow of warmer and more saline Atlantic waters to penetrate into the high Arctic. Warm waters of the Nordkapp and West Spitsbergen Currents flow in from the west and north along the troughs to the deep area of the Barents Sea and eventually interlock between Franz Josef Land and Novaya Zemlya. There is a high-latitude (72-82o N) water turnover of Atlantic water masses. Interacting with cold Arctic waters, they form a polar hydro-front (Nikiforov and Shpaiher, 1980). Underwater troughs outline biogeographical boundaries and serve as landmarks for the location of productive zones (Matishov, 1987). The intensity of water circulation as well as salt and heat transport along the sea-bottom valley system depends on inter-annual fluctuations of river runoff and sea-ice formation. 39 4. CLIMATOLOGY Based on the data contained in the section “Database” on the DVD, the following climatic fields have been created: • • Mean monthly maps of temperature and salinity distributions for the Barents, White, Kara, and Laptev Seas for the levels 0 m, 25 m, 50 m, 100 m, and 200 m. Mean monthly fields of temperature and salinity distributions along five sections (Figure 1) on the Barents, Kara, White, and Laptev Seas. 75°N 85°N 85°N 75°N 0°E 150°E E A B E D B C 30°E A 120°E C 65°N 60°E D 90°E 65°N Figure 1. Positions of the sections for which the mean monthly climatic fields of temperature and salinity have been created. A sample map of sea-surface temperatures in September is shown in Figure 2. On the DVD, in the section “Climatology,” there are color maps of mean monthly temperature and salinity fields at the levels 0 m, 25 m, 50 m, 100 m, 200 m for the 5 sections (Figure 2). The procedure for building climatic fields (an objective data analysis) used in this study corresponds to a scheme proposed by Barnes (1973) and the calculation technique of spatial data distribution and map construction (Levitus and Boyer, 1994). This procedure consists of two stages. At the first stage, a grid was created in which the Barents, Kara, and Laptev Seas were divided into squares of 50 x 50 km. Temperature and salinity profiles at all points within this 40 grid were assembled for every month and individual year. Data unavailability was marked with a special code. 75°N 85°N 85°N 75°N 0°E 150°E T (°C) 11 10 9 8 7 6 5 4 3 2 1 0 -1 -2 30°E 120°E 65°N 60°E 90°E 65°N Figure 2. Sea-surface water temperature for September. At the second stage, calculations were made of mean monthly temperatures and salinities for each of the squares in the grid. Where there was a square with less than four years worth of data, this square was not used to compute the climatology. When building the climatic fields of temperature and salinity along sections A, B, C, D, and E, data were used that were located within a distance of 50 km on both sides of the section line. The further away the station from the section line, the lesser the effect of temperature and salinity values at this station on calculated climatic characteristics (Golubev and Zuyev, 2003). The mean monthly distribution maps for temperature and salinity on the surface and at different levels presented on the DVD clearly show an annual cycle of temperature and salinity variations, primarily for the Barents Sea. For this sea, there is a clearly observed annual cycle of air-temperature variations at individual points (Figure 3). In general, for the Barents Sea, in the corresponding time periods, there is a correlation between structures of the fields of air and water temperatures in winter and summer (Figure 4 and 5). The White, Kara, and Laptev Seas are covered with ice during the winter months, which significantly reduces the amount of data available for these months. Consequently, it is very difficult to determine the annual cycle of temperature and salinity variability in these seas. However, the annual cycle of the ice edge in the Barents, Kara, and Laptev Seas can be used as an indirect proxy to describe these cycles (Figure 6). 41 1.

In addition to the traditional meteorological and oceanographic information, cruise reports also contain data on sea mammals, birds, fish, benthos, plankton, geological data, and other information. This information can be used to help provide answers to a wide range of issues; therefore, it is worthwhile to include these other variables into the database. Let us consider the data format. The current approach for standardizing data is based on the format of parameter descriptions utilized at the Murmansk Marine Biological Institute. This format has a block structure that, with slight changes, is preserved in the data description. This format consists of two blocks: STATION and TYPE. The block STATION has information about the location and time of data collection. The block TYPE contains the data consisting of the following elements: Meteorology, Hydrology, Zooplankton, Phytoplankton, Benthos, Birds, Marine Mammals, Ichthyology, Geology, Paleontology, etc. The names of the elements indicate the type of the data they contain. On the DVD, in the folder DATA\CODE\, all the code tables can be found. This format is described in more detail in Matishov et al. (2000). When formatting older data, it is often necessary to establish the longitudinal/latitudinal coordinates of the stations since the cruise reports present these in local geographical terms (e.g., 3 miles north of Kildin Island). This is very typical; many expeditions of the late 19th and the first half of the 20th centuries were conducted in the vicinity of the shore, and a mate could easily determine the ship’s location in terms of the shore outlines. Establishing the longitudinal latitudinal coordinates was required for 50-70% of all the stations on these earlier cruises. The error in determining the ship’s location is an integral part of the data-quality assessment. Therefore, the user of this database should know whether the coordinates were created from the qualitative information or they were determined by using instrumental methods. The parameter, COORD DETERM=DESCRIPTION, indicates the method of determining coordinates. If this parameter is empty, the ship’s coordinates were determined by instrumental methods. For example, on the DVD, in the file, DOC\Formats\Format1.csv, there is data from three stations. The coordinates of the first station were created from qualitative information. Let us consider examples of presenting different data types. 5.1.1 Plankton On the DVD, in the file, DOC\Formats\Format2.csv, there are examples of presenting both the quantitative and qualitative data on zooplankton. In the file, DOC\Formats\Format3.csv, quantitative data on phytoplankton are presented. In Matishov et al. (2000), there is a detailed description of these formats. 45 5.1.2. Benthos The format of the benthos data is identical to that for the plankton data because they contain the same elements: a) describing the methods for data collection and processing; b) determining the taxonomic composition of a sample; c) determining weight and/or numerical characteristics of every taxonomic type. On the DVD, in the file DOC\Formats\Format4.csv, there are qualitative (Station 1) and quantitative (Station 2) data on benthos. 5.1.3. Ichthyology The results of trawling serve as the basis for the formation of an ichthyology database. Fish caught by a trawl are sorted by species; for every species, X, its percentage in the trawl is determined. Along with this basic information, a biological analysis of 100-300 fish is accomplished. The result of this analysis is the identification of more than twenty parameters characterrizing fish condition such as weight, length, etc. (Karamushko and Alexandrov, 2003; Karamushko, 2002). Ichthyology data can be found on the DVD in the file, DOC\Formats\Format5.csv. 5.1.4. Mammals Observations of mammals from ships contain information about the ship’s location, time, and the number of mammals observed for each species (Mishin, 2002; Matishov et al., 2000; Matishov et al., 2000a). Data on marine mammals is provided on the DVD in the file, DOC\Formats\Format6.csv. 5.1.5. Birds Let us consider the data format of the observations of birds, which was collected from aircraft (Krasnov et al., 2002; Krasnov and Barrette, 2000). At any discrete moment of time, an airplane location is characterized by its coordinates, altitude, direction (course), and flight speed. The results of visual observations of birds are presented with the list of species, where the numbers for every species are indicated. An example of this data is contained on the DVD in the file, DOC\Formats\Format7.csv. 5.2. Exclusion of duplicates Our starting database for the White, Barents, Kara, and Laptev Seas included 1,506,481 stations obtained from different sources. Some of the data are outside the region represented in this atlas. These sources included the libraries in Russia, USA, Norway, Finland, and Canada as well as the databases of: • • • • Murmansk Marine Biological Institute World Ocean Database 2001 (Conkright et al., 2002) BarKode (Golubev and Zuyev, 1999). Oceanographic data (surface marine reports) from Norwegian commercial ships for 1867-1912 were provided by Torgny Vinje (Norwegian Polar Institute). 46 The probability of obtaining the same data increases repeatedly with this large number of information sources. Therefore, a search and exclusion of duplicates became an essential task. Difficulties in defining duplicates are caused by the fact that a portion of the data arrives not in their original format, but in a slightly processed format, created by an unknown technique. Let us consider a few examples of this data processing. Example 1. The coordinates of one of the two comparable stations are presented in the original format as degrees, minutes, and seconds. The coordinates of the second station are given in a decimal system, where minutes and seconds are transformed into hundredths or tenths of a degree. In this case, the conversion of the true values of the coordinates can equate to a discrepancy of a few miles. Therefore, we cannot ascertain with 100% confidence that the coordinates of the two stations coincide. Example 2. For one of the stations, the values of the parameters are presented at the observed levels, where the measurements were actually made. For the other station, they are interpolated to standard levels. The interpolation method is, as a rule, unknown. Therefore, for comparison, the station with observed levels was interpolated to standard levels. As the result, the values of the parameters from the two comparable stations will differ slightly from each other. Example 3. Every country has its own traditions in choosing units by which oceanographic parameters are measured. When combining data obtained from different countries, it is necessary to convert the data into a unified measurement system. This conversion is, thus, a source of additional uncertainty when comparing data. This is true especially for hydrochemical data. As a result of these differences in data processing, two primarily similar stations, obtained from different sources, can differ in coordinates, time of measurements at the station, and in the values themselves of the parameters themselves. In addition, the problem of duplicate exclusion becomes increasingly complicated because of the large amount of data to be analyzed. To identify “near-duplicates” a system of priorities was established: a) sources of information; b) parameters; and c) composition of observations. Among the sources of information that have the highest priority are cruise reports, ship logs, and expedition diaries. Of the lowest priority are sources of information which are a priori, i.e. known that the data contained therein were repeatedly transformed and do not contain the entire set of parameters such as vessel name, country code, etc. Among the parameters of highest priority are temperature, salinity, and oxygen. Elimination of duplicates and “near-duplicates” stations reduced the number of stations to 433,179. 5.3. Data access A provision was made to enable the user to access the data via two ways (see section, DATA, on the DVD). The first method provides data access according to the cruises. This category of data includes: • 186 cruises by the Murmansk Marine Biological Institute during 1952-2001; 47 • • • 30 cruises during which scientists of the Murmansk Marine Biological Institute collected ichthyology data; 50 cruises sponsored by different institutions during 1870-1963. This data was obtained from various libraries; 168 cruises by Norwegian commercial ships during the period 1867 - 1912. These cruises provide access to 62,453 stations within the Barents, White, Kara, and Laptev Seas. The second method provides access to the data organized by one-degree squares. The structure of this data access is as follows: First, the entire set of stations is divided into 12 subsets in accordance to the month when the observations were performed. Second, the monthly set of stations is sorted by one-degree squares. In this case, the name of the file indicates the coordinates of a one-degree square and the month. For instance, the name of the file, GN710351.cvs, indicates that it contains the data for January (the last digit in the file name), and the coordinates of the station are within 71-72o N and 035-036o E. To designate months that contain two digits, letters are used: A for October, B for November, and C for December. For instance, the name of the file, GN72135B.cvs, indicates that it contains the data for November, and the coordinates of the station are within 72-73o N and 135-136o E. For every month, a distribution map of stations is generated that allows a user to access data from a square to which the cursor points. For this purpose, it is necessary to place the cursor on the desired square and right-click on the mouse. All data are presented in the CSV format, which can easily be exported into Excel or another database application. 5.4. Inventory Figure 7 depicts the main characteristics of the primary data contained in this Atlas. Appendix A presents the data by describing the distribution of the number of stations by month for every individual year for temperature, salinity, oxygen, and plankton, as well as a summary table for all parameters. Appendix B shows maps of station distributions throughout the period between 1810 and 2001 for every individual year. The DVD disk contains monthly climatological maps and sections of temperature and salinity. 48 Time period: 1810-2001 Number of stations: 433,179 January: February: March: April: May: June: July: August: September: October: November: December: Regions Barents Sea Norwegian Sea: White Sea: Central Arctic: Kara Sea: Laptev Sea: Countries Russia: Norway: Unknown: USA: United Kingdoms: Germany: Poland: Holland: Canada: Sweden: Japan: Finland: Iceland: France: 178,356 122,593 54,386 36,469 17,426 6,648 2,740 1,242 1,226 383 340 221 177 164 219,077 160,512 20,348 13,870 13,591 5,781 16,512 19,621 30,363 34,424 41,612 59,163 47,791 62,710 55,726 29,953 17,620 17,684 Number of stations vs. year 25000 20000 15000 10000 5000 0 1870 1900 1950 2000 Figure 7.

ELECTRONIC BOOKS This section of the DVD includes electronic versions of various books about the history of Arctic exploration, as well as cruise reports and articles, which contain original data and descriptions of measurement techniques. Most of these publications are considered “rare” books and are, thus, not easily accessible to the public. The quality of some of the text in the PDF files is far from adequate, which is due to imperfect book scanning technology (a digital camera was used). However, the authors considered it appropriate to include these books as they make an important contribution to this Atlas.
