19. Work underway to establish

20. No. However, some of the Alaskan data are stored at the NSIDC in Boulder, CO

21. We are working to provide data through:
http://iop.apl.washington.edu
However, this is not yet operational.

22. Data will be archived through the Arctic LTER database,
http://ecosystems.mbl.edu/arc/

23. http://www.uaf.edu/toolik. Climatic data is still at the Arctic LTER site (specified in
previous submission), but will probably migrate to UAF in the future.
Would you prefer a central AON archive site to house your data?:

1. does not matter

2. No, we have neen contributing data for several years (before AON)

3. Our current arrangements work well for our own needs; the main new need is to
ensure seamless collaboration with other AON/IPY projects. To achieve this a central
archive is less important than clear and simple metadata protocols

4. Yes, along with mirrored data availability at sites listed above

5. No preference. I would not mind having the data available from multiple sites. E.g. we
also archive at NSIDC.

6. Its less important that the data physically reside in an AON archive than that there be
strong and lasting links between web sites.

7. N/A

8. OK but not solely.

9. Not necessarily.

10. No, but we want to be sure that we can share data with other projects.

11. yes

12. yes

13. yes

14. Having a central AON site is essential.
We would still maintain our own archive in addition.

15. We would like to discuss this during the workshop.

16. yes

17. No

18. It would somewhat helpful but I do not believe it is absolutely necessary. For
maximizing value though, it probably should be at least all be linked to a single portal.

19. We will consider this option.

20. Yes

21. It might be easier for us to correct processing mistakes on our own site. However, a
central site that logged users, and could thus send out notifications of changes, could be
very useful. Ultimately, we will probably always serve from our own site, even if in
parallel with the AON site.

22. Not necessary, but it might be helpful for back up

23. Would be nice, but is not necessary.
What is the data type and/or parameters to be included?

1. all

2. air temperature, relative humidity, wind speed and direction, soil temperature,
barometric pressure, atmospheric longwave radiation, emitted longwave radiation,
incident shortwave radiation, reflected shortwave radiation, net radiation, precipitation,
stream discharge

6. Data from each buoy includes: position, air temperature, barometric pressure, snow
depth, ice thickness, vertical profiles of ice temperature.

7. We will archive data and metadata from AON projects. Data will be varied in type and
format

8. Ocean temp salinity, oxygen, velocities, diffusivities, bottom pressure, ice thickness,
temperature profile, atmospheric pressure, atmospheric temperature, solar radiation

9. P,T,S,and ice drift.

10. We anticipate integrating our project with Arctic-RIMS using the National Snow and
Ice Data Center called EASE-Grid. See: http://nsidc.org/data/ease/
Variables will be coded at the grid level (25km), national, subnational (e.g. province),
and administrative subdivision (e.g. borough, municipality). We also anticipate producing
point data at the community-level.

11. ascii column format: pressure, temperature, salinity, velocity

12. time-height and timeseries of observables from a given site. The data files will
include cloud water content, particle size, and extinction for both liquid and ice phases.
In addition, some information will be included on cloud water paths, optical depths,
vertical locations, presence, phase classification, vertical velocities, and radiative forcing.

13. atmospheric concentrations of BrO, O3 and CO2

14. Mooring data - currents, TS, biooptic data, some ice tracking and rough ice thickness

CTD data - standard CTD measurements, nutrient bottle samples

15. Data is temperature profiles with error in altitude. Maps are images. We are currently
refining how the two data sets will be integrated, and anticipate using the AON workshop
as a basis for defining the final data types with our international IPY partners.
16. Plant growth, Plant phenology, plant cover, soil/air temperatures

17. Transcripts; audio recordings; video recordings; photographs; maps; artwork;
scientific measurements. Parameters vary between communities and projects but
include environmental parameters such as snow, sea ice, water levels, vegetation,

Regular intervals: weekly-plant phenology (bud/leaf/flower/fruit status), plot reflectance
spectra (2 nm intervals from 310-1100 nm), NDVI images (jpeg format, 3.1 Mpixels); one
time measurements at peak season (leaf nutrients CNP%, leaf isotopes (13C,18O per
mil), litter nutrients (CNP%), soil solution nutrients (NP m or micromolar), radiocarbon of
respiratory CO2 and soil fractions, point quadrat (species identity and height of top and
bottom hit in a 10 x 10 grid lain over 1 m2.

19. See reply to first question. The interval of the time-series will be 3-4 hrs.

20. Ground (permafrost) temperatures at multiple depths recorded with various time
intervals.

21. Please see above. Metadata, full time and geolocation stamps will be included.
Although we are willing to share our engineering data, we do not plan to serve it
publically due to the specialized nature, limited audience and large effort that would be
required.

22. We will provide metadata in the LTER formats, since our data will be archived in the
LTER database.

23. We are still developing metadata, and are open to suggestion.
What is the time (and space, if you have more than one site) resolution of the
data?:

1. 1. 2004-present
    2. 2003-present

2. We report hourly data

22. Flux data will be corrected to 0.5 hour averages

23. Environmental data collection by TFS began in October 2006, but climatic data is
available back to 1988 through the Arctic LTER. Data is collected in the vicinity of TFS.
Please describe any data quality control that you apply to the data:

1. LEVEL 1 RAW DATA is received from each ITP several times per day (after each
profile) and made available within a few hours at ITP data. The locations are unfiltered
and the scientific and operating data are extracted from the binary profiler file and saved
in MATLAB format files, but no other processing, cleaning or smoothing is performed.

LEVEL 2 REAL TIME DATA with preliminary processing is updated multiple times per
day. The location data are filtered and interpolated, while the scientific and operating
data are averaged in 2 m bins and plotted.

Level 2 data from the ITPs deployed in the Beaufort Gyre are available:

2004 - ITP2

2005 - ITP1 - ITP3

2006 - ITP4 - ITP5 - ITP6

LEVEL 3 ARCHIVE DATA includes all de-spiking, filtering, and corrections and will be
updated several times per year at ITP data.

A full description of the ITP data processing procedure will be provided here at a later
date.

2. Before it is sent to NSIDC we do a quality control check.

3. Data are scanned for outliers, filtered, calibrations checked regularly. Integrated
values over half-hourly and longer time intervals calculated during post-processing.

4. With the exception of near-realtime data (see below), all data sets will be subjected to
QA/QC consisting of calibration (where necessary), removal of erroneous data points
(equipment malfunction, data loss), and flagging of suspect data (potential calibration
errors, etc.)

5. Real-time data are QC'ed as part of the buoy-qc efforts of the operational
communities of the DBCP and JCOMMOPS. Research data are QC'ed at the Polar
Science Center.

6. We have two layers of quality control. The first is a computer program that removes
incorrect or incomplete data. The second is a human check of the data for more subtle
problems.

7. N/A

8. We work hard to ensure the data we archive is usable by third parties.

9. Filtering and averaging.
10. Maintain original links to data sources; record all procedures use to reformat/recode
data to fit project requirements; obtain qualitative assessment of quality from source
experts; record observations of data anomolies.

11. standard processing, de-spiking

12. The original data sets are produced by other programs (DOE ARM, NOAA, etc.) who
perform their own data quality including data continuity, instrument health, and
measurement quality. Quality control on our derived data sets is based on manual
review of data images and on comparison of results with independent measurements
such as those from aircraft in situ campaigns.

13. no response

14. Pre and post mooring calibration
Pre and post CTD calibration
In house processing and quality control.

15. The retrieval of temperature profiles includes error analysis. error files are computed
with temperature files. Satellite data are provided with levels of quality control.

16. look through it to make sure it appears correct and do preliminary analysis to look for
outliers

17. To be determined.

18. Data are double checked upon entry, max, mins, and distributions visualized for
outliers. Outliers are checked against original data sheets. Nutrient analyses are run
twice. Point frame data are entered using MS-Access with restricted entry so only
correct species can be entered with heights restricted to realistic range. Spectra are
referenced against standard and visually inspected for problems.

19. Data will be fully quality-controlled before release. Subsets of more robust data will
be available in near-real time from our website.

20. Temperature sensors are normally tested in the ice bath for 0C. Other types of
quality control also have been used

21. We would prefer to fully process the data before release. However, this precludes
near-realtime release of glider data, and delays dissemination. We could release
uncontrolled preliminary products, if there is a real need for this.

22. Eddy flux data will be checked and bad data (because of instrument failure or strong
winds, etc.) will be removed. Data interpolation and Kalman filtering to deal with data
gaps will be carried out at the MBL. Other types of data (temperature, etc.) will be
summarized and checked for outliers, etc. Data on vegetation will be checked for
transcription errors and outliers, and will be summarized.

23. Data are checked for outliers and entry errors (for phenology data). Photographs of
snow cover are rectified by the TFS GIS department.
                     Will you be collecting data in non real-time?

1. both in real and non real time depending om project

2. Generally no.

3. Mostly not real-time although wireless communication to data loggers will be used to
check for instrument malfunctions, and for coarse estimates of fluxes and climate
parameters; most data require significant post-processing.

4. Ice thickness surveys and ice sampling/optics data will be limited to individual
sampling campaigns with subsequent data processing.

5. No

6. No.

7. N/A

8. Yes, once per year at our mooring and bottom pressue recorders. We pick up these
data once per year.

9. No.

10. This project is focused on existing data. We also will identify near-real time data
streams that closely match existing data streams (e.g. sea ice conditions).

11. Yes, one year of data from each of two moorings will be collected in August 2008.
No data will be available before this.

12. No response.

13. Early spring period will be real-time data
All other times will be weekly transmission
No summer data collected

14. Moorings - as described above

15. No

16. data collected during the summer and to be archived in the late fall to early winter

17. To be determined.

18. All data will be non-realtime. It will all be manual at regular intervals or for single
events at peak season. Regular intervals: weekly-plant phenology (bud/leaf/flower/fruit
status), plot reflectance spectra (2 nm intervals from 310-1100 nm), NDVI images (jpeg
format); one time measurements at peak season (leaf nutrients%, leaf isotopes (per mil),
litter nutrients (%), soil solution nutrients (mmolar), radiocarbon of respiratory CO2 and
soil fractions, point quadrat (species identity and height of top and bottom hit in a 10 x 10
grid lain over 1 m2.
19. Our data are transmitted back from the buoys in near-real time (twice a day)

20. Yes. Typically once per year data collection

21. Yes. Moorings serviced in autumn of each year. Data processing requires several
months following recovery.

22. Yes. Vegetation data will be non-real-time, with collection and summarization
occurring once per year. Stream chemistry data will also not be collected in real-time.
Eddy flux data will be collected in real-time. Flux data at Cherskii may not be able to
leave Russia in real-time, we hope to do much of the processing in Cherskii, and send
out the corrected data.

23. All data are non-real-time. The cameras are connected to dataloggers and
downloaded periodically. Phenology data are collected by observers.
What data will be collected in real-time?:

1. T,S

2. Most data is collected in near real time (within 1 hour) via radio network however data
transmission success depends on the weather.

3. Weather and microclimate, coarse flux estimates

Please describe any real-time quality control process that you do:

1. Same as earlier QC question.

2. Although we make the data available there is no immediate quality control of this data

3. None in real-time

4. on ice mass balance data bad data points due to equipment malfunction (as
identifiable through exceedance of pre-set thresholds) are automatically edited out; for
all time series a data set subjected to QA/QC as described above is produced and
released after field season

5. Data are part of the buoy-qc monitoring efforts of the DBCP and JCOMMOPS.

     Are you interested in receiving real-time data delivery of AON data at you
                                    institution?

1. yes, all ocean and sea ice data

2. Not at this time.

3. Perhaps--don't know what is available

4. tbd

5. Maybe. We already get the data once per day from Argos, but when we have tried
going to more frequent updates, we get inundated with redundant or repeating data.

6. We are more interested in accessing AON from web sites.

7. N/A

21. No response.

22. I'd rather have access to the corrected data, not the raw data. I'm not sure that this is
necessary, though perhaps it will turn out to be more useful than I see right now.
23. no response
Will you be collecting data that require "special handling"

1. no

2. No

3. None

4. We are working with local observers in coastal villages who will record ice
observations and related activities. This data will be collected according to federally
mandated procedures and under guidance review of Institutional Review Board; archival
and dissemination of the data will occur in collaboration with SIKU IPY Project (Dr. I.
Krupnik) and ELOKA AON Project (Dr. Shari Gearheard)

5. No

6. No.

7. N/A CADIS will be equipped to handle such data should the AON investigators need
assistance

8. No.

17. Yes

18. No

19. no

20. No

21. Possibly (marine mammal acoustics- Stafford and Simon)

22. Vegetation data is in a very different format from the flux data, but probably doesn't
require special handling or security.
23. no response
  Do you require other complementary data in order to complete your research?

1. no

2. Usually not, but we do work with several other groups.

3. Yes; satellite data

4. no

5. No

6. Yes, we will be integrating our observations with other surface-based and satellite
results.

7. N/A

8. remote sensing. extensive ice daa, atmospheric data, other bottom pressure
measurements are especially useful

9. In addition to the ocean data, we use meteorological, ice, and satellite data in our
analysis.

10. We don't require complementary data to realize the goals of the project, but the
project will be greatly enhanced if we can access data from other projects.

11. not necessarily

12. Most data used in our analyses can be considered "complementary" in that they are
produced by other programs.

13. routine surface observations, met data, SST, satellite data of BrO, ice cover

14. Yes

15. Satellite data and meteorological analyses.

16. data from collaborators

17. Some remote sensing data might be interesting to overlay with local observations.
This is a future activity though.

18. Weekly MODIS EVI data would be helpful for Barrow, Atqasuk, and Toolik. Weather
data from those three sites also will be helpful (Toolik is available from LTER).

19. Our buoy will typically deployed with WHOI ice-tethered temperature and
conductivity profilers, PMEL met stations, and CRREL ice mass buoys. All of these data
are complimentary to one another.

20. Yes
21. Atmospheric data, remote sensing, oceanographic data from the surrounding regions
would all be useful as we try to understand this region.

22. We require data from our collaborators in Abisko, Zackenberg, and Canada to truly
complete our pan-arctic network of flux data. Their data will be available, but possibly not
on exactly the same time frame or in the same format as our data. It would be helpful to
get access to data from complementary AON projects such as the permafrost project
and the snow project.

23. no response
Please provide your perception of the top priority data management tasks that
would make AON most useful/successful to the broader community:

1. The system has to be simple with a minimum bureaucracy linking all data sets via
internet rather via managers and middlemen
Only raw data or minimum processed data should be collected. This will significantly
reduce cost of this system.

2. No response.

3. We need a clear definition of how these data are to be used--what are the research
questions to which they will be applied?

4. Having an accessible, well-organized archival and dissemination site and ensuring
that in addition to dissemination within scientific community, thought be given to how to
process and disseminate data in stakeholder-friendly fashion.

5. Easy access.

6. Rapid and easy access to data.

7. Easy data and metadata access

8. our problems are just having toime to qc and finish the basic processing. The external
problem is slowness of archiving

9. Simple standardized datasets of all paramters in near-real time.

10. retrieval of data streams at varying spatial and time scales.

11. a centralized data center on the web

12. A user-friendly, web-based interface for serving AON-related data to the scientific
community

13. no response.

14. Collation of AON data at one, easily accessible site.

Maintaining an overview of programs and data.

Permanent archiving of the data.

Easy data submission process (to aid getting the data collated quickly).

QC of the data to be done by PIs.

Easy search by region, date, measurement
subsetting by region, date, or measurement
Prompt collation of data once collected.
Clear graphical representations of data availability by maps and timeliness.

(These comments are collated from all PIs.)

15. We are particularily interested in how our data can be presented as part of an
integrated AON. We are intererested in discussing if AON will present a single
integreated virtual observatory.

16. 1 providing a temporary secured ftp space for PIs in collaborative projects to
exchange data with collaborators
2 providing easy access to data
3 providing agreed upon citation format for acquired data
4 tracking data downloaders for proper citation

17. no response

18. Linking the data into a system such as the trial Ameriflux "data cube" model for ease
of retrieval and visualization.

19. Centralized archiving and/or linkning to full q-c historical data sets, all Arctic.

20. Easy access and convenient and easy to use search engines

21. no response

22. Make it easy to share data among the AON projects, make it simple and easy to
contribute data, help with the data management and generation of metadata, if you want
them in a different format than what we are currently prepared to provide.

23. no response
Do you have other special data support requirements or comments?:

1. No

2. No response.

3. None

4. Not at this time.

5. No.

6. No.

7. CADIS will develop to be a major access point for AON data. Our success will rely on
the cooperation of the AON investigators.

8. Not at this time

9. No.

10. We think that the Arctic-RIMS database contains many of the desired features to
support inter-disciplinary research within AON.

11. No response.

12. no

13. no response

14. One thing I would stress and stress again .. (you are good at it, I think, but others are
not) .. when we talk about data bases and archives, can we make sure there is an ASCII
version of the data - not just matlab, not just excel .. but something everyone everywhere
can read. (I've just been through a round with someone who sent me a matlab file which
I am unable to open. 100 years from now, we need the data still to be readable. If the
files are small enough to be ascii, let's do it .. if not, then let's pick an easily readable
standard, and not expect someone to buy some commercial software. I know even the
Europeans don't often buy Matlab .. and I fear we are excluding the less developed
countries too.)

15. Not that we are aware of at this time.

16. I am concerned about other researchers using my data without including me as an
author, proper citation, or improperly using the data (bad conclusions that may be biased
due to how data was collected etc)

17. no response

18. no response.

19. no response
20. No

21. no response

22. Not at this time. Sorry for the delay in responding. This is a collaborative project with
Gus Shaver, and he has responded to this questionnaire also. Hopefully we are not
contradicting each other!

23. This is an addendum to the original questionnaire that I filled out. We would like to
include at least a link to the baseline environmental data collected by TFS within CADIS,
because we regard these data as being complementary to, and part of, our AON effort.
