ABSTRACT:
                           Nutrient data set for the Ipswich River main stem, major tributaries, and headwaters. Data are from base flow conditions. S
                           were from July 1998 to July 1999, and were collected and analyzed by MBL




METHODS:
                           Ipswich River main-stem and tributary samples collected and analyzed by MBL (July 1998 to July 1999)
                            "River km" indicates distance from "zero" at mouth of Plum Island Sound which is 7.358 km downstream of the Ipswich Sylvania

    Cell: A2
Comment: The dataset identifier is a unique label for the data set that
          is constructed from the file name without the file extension,
          followed by a version number, e.g. LTE-MP-LPA-biomass.01. If there are
          any changes made to the metadata or data files the version
           number is incremented and a note is added in the Log of Changes section.


    Cell: A3
Comment: A unique number assigned by the Information Manager
          for use with Metacat server. You DO NOT need to enter anything.

    Cell: A4
Comment: Year of public release of the data. Filled out by the Information Manager.
           You DO NOT need to enter anything.

    Cell: A5
Comment: This is the URL for the metadata file. It is filled in by the Information Manager. You DO NOT need to enter anything.



    Cell: A6
Comment: A title for the dataset. It should be less then 200 characters
          long and should describe the data collected, geographic context,
          research site, and time frame (what, where, and when).


    Cell: A8
Comment: List here the name and address of the person,
          most knowledgeable about the data set.
          If the dataset has more than 1 investigator,
          please enter the information for them in the column to the right.


    Cell: A20
Comment: PIs, RAs or Techs who were also involved in the data collection or compilation. Separate names with a comma.

    Cell: A22
Comment: The format of the data file should always be ASCII comma delimited with a .DAT extension. The first line of the data file should be a comma delimited list
          of the variable names. A spreadsheet or database file may also be included, but it must have the first row with the variable names and only data below
          the names. There can not be any other stray data on the sheet.


      Cell: A23
Comment: The URL for the data file that this metadata describes. This will be fill in by the Information Manager. You Do NOT need to fill in.

    Cell: A24
Comment: File naming convention is as follows: Each data file will carry the same name as the meta-data file, with the exception of the extension. Data files must be
          comma delimited ascii (.dat extension). An additional file can be Microsoft Excel file (.xls). Documentation meta-data files will be generated in this Excel
          data template and converted later to EML and HTML. The files will be named starting with a three letter acronym of the main research theme of the data
          set (see table below). A second 2 or 3 letter acronym is appended that describes the research site (see table below). A descriptor is then appended that
          briefly describes the dataset. For instance, dissolved oxygen transect data from the Parker River is named "EST-PR-O2", and tidal-creek nutrient data
          from the long-term experiments is named "LTE-TC-NUT". The data-manager may edit file names as appropriate.

            These same naming methods apply for the PIE-LTER site names. All site names will have the same three and two letter descriptors, and an appended
           descriptor. For instance, the Middle Bridge YSI monitoring station is named "MON-PR-MBYSI". This descriptor will either be an abbreviation describing
           the station or a river kilometer distance that describes its location along one of the rivers in the Plum Island ecosystem. Please use the River Kilometer
           Image (http://ecosystems.mbl.edu/PIE/data/protocol/piestati.jpg) as an aid in determining names for sampling locations. The image is color-coded to
           show which two-letter site descriptor code should be used in station naming. The convention that has been established for determining locations on a
           river based upon river kilometer is to set the mouth of Plum Island Sound as 0.0 km. River kilometer markings are clearly labeled in this image as is the
           0.0 km starting point in the Sound.

Comment:
          Describe the general procedure of how the taxonomy was determined (keys used, etc.),
           should include a general textual description of all flora/fauna in the study (scope), as
          well as how finely grained the taxonomy is broken down to – for example “family” or
          “genus and species.”

    Cell: A51
Comment: Genus and /or species names for all organisms relevant to the study.
          Separate the organisms with a semicolon or comma. For subspecies and variety use ssp. and var. For example
          Carex aquatilis var. aquatilis; Carex atlantica ssp. atlantica
          Note: It is good practice to check the taxonomic name with a source such as Integrated Taxonomic Information System (www.itis.gov)

    Cell: A54
Comment: Words that may be helpful in cross-referencing or cataloging the data. These should be in lower case format, unless the word is a proper name.

    Cell: A124
Comment: Add rows as needed with a separated row for each variable name. The variables Date and Comments must be
          included in every data file.

           Date should be in the format DD-MMM-YYYY (i.e. 01-Jun-1988). This format avoids confusion between Canadian
           and USA forms of dates.

           Comments must be the last column in the file, and includes any additional information about individual data points.
           All Comments for a data point must be entered on a single line, which can be no longer than 250 characters.

           Variables for time in Hours are to be in 24 hour format (not AM or PM) and based on Eastern Standard Time, not Eastern Daylight Savings Time. Entries
           should be 4 places, hours and minutes, preferably without any punctuation (examples 0458 or 2133). Individual PIs need to be responsible for making
           these time corrections.

           Missing data shall be designated by a Missing Data Value. The value used should be noted , i.e. BLANK, period, N/A. The value -99999 is the prefered
            missing data value.

Comment: Units field: If variable is a number, e.g. ratio or interval,
          use drop-down list to choose a unit listed. If not listed
          then enter the units using a format similar to the other
          units.

    Cell: D124
Comment: Measurement Scale field: Enter either nominal, ordinal, interval, ratio, datetime.

            Knowing how data are measured and recorded is important for proper statistical analysis.

            1. Nominal Data
            Named categories, a list of coded values, or plain text descriptions. There is no ordering
            between the values, e.g. male/female, evergreen/deciduous. It makes no sense to state
            that evergreen > deciduous.

            2. Ordinal Data
            Named categories but are in order with reference to one another. However there is no
            constant distance scale between them, e. g. low, medium, high. An ordinal scale only lets
            you interpret gross order but not the relative positional distances

            3. Interval Data
            Ordered, constant scale, but no natural zero. Differences make sense, but ratios do not
             (e.g. temperature in Celsius or Fahrenheit where 30°-20°=20°-10°, but a temperature
             of 30° is not twice as warm as one of 15°.

            4. Ratio Data
            Ordered, constant scale, natural zero,e.g. height, weight, age, length.

            5. Datetime
            Measures of time.


    Cell: E124
Comment: Codes Definitions:
          For any variables that are coded, list the values/definitions
          for codes used. Format the list as a vertical-line separated list, e.g.:
          N=fertilized with nitrogen only | P=fertilized with phosphorous only | NP=fertilized with nitrogen and phosphorous | C=control (not fertilized).
    Cell: F124
Comment: Number Type: If variable is a number, e.g. ratio or interval, then select from the drop-down list.

           real: numbers that contain fractional or decimal elements
           integers: non-fractional positive or negative numbers
           whole: numbers of positive integers
           natural: whole numbers except zero.

Comment: Date Time format field: Enter the datetime format
          (ex. DD-MMM-YY) for variables that are dates and or time.

           -99999 = not measured | -88888 = data lost etc
