BCO-DMO is the Biological and Chemical Oceanography Data Management Office. We help oceanography researchers who are funded by the National Science Foundation’s (NSF's) Division of Ocean Sciences' (OCE) Biological or Chemical Oceanography Sections or the Division of Polar Programs' Antarctic Organisms & Ecosystems Program manage their data, making them accessible over the internet.
BCO-DMO is primarily funded by an NSF grant (OCE-1031253).
BCO-DMO is made up of people with a very strong interest in making your data useful to you and to others. We have decades of experience (some of us are older than we look) managing data from many domains including biological, geochemical, geological, and physical oceanography.

NSF has a general, but well-defined data management policy section contained within the Grant Proposal Guide (GPG). However, specific data management requirements of a given Directorate, Division, Program or other NSF Unit may supercede this general policy. The Division of Ocean Sciences (OCE) updated its Sample and Data Policy in 2016. Of note is the requirement that data collected by researchers funded by NSF must be made publically available within two years of the data collection/production.
Every proposal to NSF must include a Data Management Plan (DMP), no longer than two pages, which includes information about how the results of the proposed research will be made available and accessible to the public in a timely manner. BCO-DMO has guidelines for investigators preparing NSF Data Management Plans (DMPs), including a DMP Template.
Once you have your NSF award number is a good time to get started by contacting us. Our How to Get Started page provides details, but the first step is just to let us know via email that you want BCO-DMO to work with you. There are resources at BCO-DMO that can help you even as you prepare your proposal: please see information about NSF's data management plan and help in planning your data collection effort.
You can wait until you receive your NSF award and know your award number before you contact us. We can collect much of the preliminary metadata about your project directly from NSF.
BCO-DMO can deal with a wide variety of data, including but not limited to biological, chemical and physical oceanography measurements and experimental and model results. We routinely deal with CTD, biological abundance, meteorological, nutrient, pH, carbonate, PAR, sea surface temperature, heat and momentum flux, sediment composition, trace metals, primary production, and pigment concentration measurements, and with images and movies. While sequence data should be sent to GenBank, sequence accession numbers and the associated environmental data can be contributed to BCO-DMO and we can provide the links to the sequence repository. This ensures that the data are discoverable from BCO-DMO's website. Please see "Contributing Sequence Accession Numbers" for more information.
Usually, measurements come to BCO-DMO as ASCII or spreadsheet files. However, we try to be flexible and are willing to work with whatever reasonably organized format the investigator uses. We have some suggestions for what formats are easier to work with, but these are only suggestions, not requirements.
Yes, we do. Please review our Submitting Data in a Spreadsheet document for some guidelines.
BCO-DMO does not want to duplicate the effort of other data assembly centers (DAC), so if the data are accessible from a recognized DAC (like the LTER network office) and the DAC or the scientist takes responsibility to ensure the data are properly archived at a recognized national archive, we believe the NSF guidelines/requirements are met. However, providing access via a project- or program-specific website is not likely to be sufficient because these types of websites usually do not have the funding to provide the longer term data and metadata access implied by the requirements.
It is important that the data be managed in such a way that they are discoverable and reusable by others. This means that there is sufficient metadata to support proper data reuse and that the actual data, not just resulting graphs, are accessible. Although your data may already be online, there may still be value in having BCO-DMO involved if the dataset is of interest to scientists using BCO-DMO and there is benefit in having these data accessible directly from BCO-DMO.
No. BCO-DMO uses a distributed data management system called JGOFS/GLOBEC that supports distributed data servers. As long as your data can be placed on a Linux or Unix based machine that has a web site, your data can remain on your machine. The approach has the advantage of always serving the most up to date and accurate version of the data.
For large volumes of data we suggest using Dropbox. Please see https://www.dropbox.com/. If you don't have your own Dropbox account, a BCO-DMO Data Manager will set up a folder for you and send you a URL that will allow you to upload your data into our Dropbox using your browser. Another option is to make the files available online (ftp, Google Drive, etc.) and let us know how to get them. If you still have questions, please contact us for alternative approaches.
The information contained in the metadata should be sufficient to allow another researcher to make use of your data, and, in a sense, to be able to recreate it. For example, it should include the sources of your data (names of the instruments or software model(s) used), how you processed these data, and how they were analyzed. If you have this information contained in a paper, you can duplicate it for the metadata. By all means, include the reference to this paper too in your metadata. Names of the field names (columns) and their units should be described completely.
BCO-DMO is funded to work with researchers funded by the NSF Geosciences Directorate's Division of Ocean Sciences' Biological and Chemical Oceanography Sections and the Division of Polar Programs' Antarctic Organisms & Ecosystems Program. We have some latitude in working with researchers outside of these sections and would be happy to learn more about your project to see if BCO-DMO should be involved.
We are glad you asked! Please read our Data Management Best Practices Guide.
Data can be downloaded from BCO-DMO as tab-, comma-, and space-separated ASCII files, Matlab binary files, netCDF format (if the data are amenable to this format), and ODV format (if the data are amenable to this format). Data can also be accessed using Open Geospatial Consortium’s (OGC) Web Mapping Service (WMS) and Web Feature Service (WFS) through our MapServer interface. For more information on finding and downloading data using the BCO-DMO data system, please refer to our Data Access Tutorial (PDF).
Any standard web browser including Firefox, Chrome, Safari, as well as Internet Explorer can access data managed by BCO-DMO. We provide both text based and geospatial access. For more information on finding and downloading data using the BCO-DMO data system, please refer to our Data Access Tutorial (PDF).
Please refer to our citation recommendations and usage guidelines.
Most of the data BCO-DMO manages is archived at NCEI.
- For NSF-sponsored Physical Oceanography projects, investigators are encouraged to contact the CLIVAR and Carbon Hydrographic Data Office (CCHDO) or archive their data directly with the National Centers for Environmental Information (NCEI).
- For marine geology, contact the Interdisciplinary Earth Data Alliance (IEDA) group hosted at Lamont-Doherty Earth Observatory, Columbia University.
- For projects supported by NSF Arctic Sciences Program (ARC) investigators, the newly formed Arctic Data Center which succeeds the Advanced Cooperative Arctic Data and Information Service (ACADIS), should be contacted. The Arctic Data Center is supported by NSF and is led by the National Center for Ecological Analysis and Synthesis (NCEAS) at the University of California Santa Barbara, to develop and curate the NSF Arctic Data Center, an archive for Arctic scientific data as well as other related research documents.
- Gulf of Mexico Research Initiative (GoMRI) funded projects can submit data to their regional GoMRI location. See https://data.gulfresearchinitiative.org/about for additional information including their data management plan under the "Design and Management" menu option.
To request the R2R eventlog capability on your cruise, use the ELOG request form at http://www.rvdata.us/contact/elog.
The JGOFS/GLOBEC data management system provides the primary means of accessing the online data managed by BCO-DMO.
