1. Biological and Chemical Oceanography Data Management Office 1 of 13 An Introduction to the Biological and Chemical Oceanography Data Management Office (BCO-DMO) Cyndy Chandler BCO-DMO Woods Hole Oceanographic Institution 8 September 2007 GEOTRACES Data-Model Synergy Workshop Delmenhorst, Germany

2. Biological and Chemical Oceanography Data Management Office 2 of 13 GEOTRACES has been identified as a project that will generate data and results of interest to the scientific community served by the Ocean Carbon & Biogeochemistry Office

3. Biological and Chemical Oceanography Data Management Office 3 of 13 The Biological and Chemical Oceanography Data Management Office (BCO-DMO) The Office is located at the Woods Hole Oceanographic Institution. The Web-site is: http://www.bco-dmo.orghttp://www.bco-dmo.org The Office is managed by: Robert Groman (rgroman@whoi.edu) Cyndy Chandler (cchandler@whoi.edu) David Glover (dglover@whoi.edu) Peter Wiebe (pwiebe@whoi.edu) The BCO-DMO was initially created in late 2006 to serve PIs funded by the US NSF Biological and Chemical Oceanography Sections. It has since been expanded to serve the data management needs of the Ocean Carbon and Biogeochemistry group of researchers in the US. It is a location from which marine biogeochemical and ecological data and information developed in the course of scientific research can easily be disseminated, protected, and stored on short and intermediate time-frames.

4. Biological and Chemical Oceanography Data Management Office 4 of 13 the BCO-DMO is a combination of the formerly independent data management offices for US GLOBEC and US JGOFS BCO-DMO will continue to manage the US JGOFS and US GLOBEC data collections as well as data from new programs, including programs associated with the OCB DMO (CARIACO, EDDIES, MedFlux, SOFeX, VERTIGO) The Biological and Chemical Oceanography Data Management Office (BCO-DMO) U.S. JGOFS

5. Biological and Chemical Oceanography Data Management Office 5 of 13 The BCO-DMO data system will be designed to be interoperable with other data systems to facilitate discovery of and access to ocean science data and supporting documentation. U.S. GEOTRACES U.S. SOLAS The relationship of BCO-DMO to existing and proposed entities.

6. Biological and Chemical Oceanography Data Management Office 6 of 13 Guiding Principles of Data Management “a stewardship philosophy” quality assurance of data treat all information as data data that lacks sufficient metadata has limited value beyond the research program for which it was collected metadata should include sufficient information to support discovery, value assessment and accurate secondary use (re-use of data) The data collection generated by a research project is a valuable component of its legacy.

7. Biological and Chemical Oceanography Data Management Office 7 of 13 Important Concepts it’s all data ! decide what metadata is important to support GEOTRACES science store metadata in a database that will enable custom generated lists of selected information, in a variety of formats, and be compatible with various standards … The metadata database will also support data discovery through a robust search interface.

8. Biological and Chemical Oceanography Data Management Office 8 of 13 Challenges heterogeneity of results... both data type and content type model results...what to preserve ?  description  input  code  results management of full set of results and design of single interface that provides access to all result types

9. Biological and Chemical Oceanography Data Management Office 9 of 13 a list of all expected results from a sampling program (cruise) that includes PI/co-PI names and brief description of expected measurements for example: PIname: Robert Anderson co-PI: none Measurement: Radionuclide data from bottle samples including: temperature, salinity, thorium-232, thorium-230, protactinium-231 and beryllium-10 Data Inventory

10. Biological and Chemical Oceanography Data Management Office 10 of 13 Metadata project, people and dataset profiles for example a dataset profile contributed with each data set includes: PI name(s) Affiliation when data collected (e.g. Institution) dataset description: Particulate Organic Matter (POC and PON) project: GEOTRACES platform type (e.g. ship, mooring, satellite) deployment (e.g. cruise ID)

11. Biological and Chemical Oceanography Data Management Office 11 of 13 Sampling Event Log one event log for each cruise a comprehensive list of uniquely numbered sampling events, including: event number, start and end date and time (in GMT/UTC), time zone, latitude and longitude [decimal degrees], sampling device name or code, person’s name responsible for sampling, station/cast number, comments and optionally including: local date/time, project-specific information GEOTRACES DMC has suggested tagging each sample with a unique sample ID that is a combination of cruise, station, cast and bottle number

12. Biological and Chemical Oceanography Data Management Office 12 of 13 GEOTRACES Data Management as proposed in the GEOTRACES DMC report (Dec. 2005) oversight of DM is responsibility of DMC and a Data Liaison Officer (located in IPO) reporting to SSC the DLO would be responsible for maintaining lists of GEOTRACES cruises (and contributing projects) and data sets from participating national programs details of BCO-DMO support for US GEOTRACES data management should be worked out in the near future Intercalibration Cruises: present an opportunity to establish best practices for sampling and analytical protocols and also metadata essential to support GEOTRACES science themes

Anyone from GEOTRACES attending? 17-21 September 2007: Shanghai, China IMBER / LOICZ Continental Margins Open Science Conference Abstract submission is closed but registration is still open. https://www.confmanager.com/main.cfm?cid=792 https://www.confmanager.com/main.cfm?cid=792 Session 1 Ocean-Shelf Biogeochemical Exchanges Session 2 Continental Shelf Biogeochemistry and Couplings with Benthic Systems Session 3 Continental Shelf Carbon in a High CO2 World Session 4 Continental Shelf Ecosystems from High to Low Latitudes Session 5 Integrated Observations and Modeling: Visions and Reality Session 6 Eutrophication and Oligotrophication in Coastal Systems Session 7 Low Oxygen on Continental Shelves Session 8 Sustainable Use of Continental Shelf Resources

15. Biological and Chemical Oceanography Data Management Office 15 of 13 IMBER / LOICZ Session 5 Session 5) Integrated Observations and Modeling: Visions and Reality Focus: Long time series, remote sensing, and observation systems. New approaches for on-line and synoptic monitoring. Assimilation of these data in multi-dimensional, coupled physical-biological models that address continental shelf processes, cross-shelf exchanges, and shelf break dynamics. Ecosystem models in pursuit of better understanding of human-induced stresses, which compromise biodiversity, ecosystem stability and biogeochemical processes, are sought.
