Welcome to the Arctic research website at

UMCES Chesapeake Biological Laboratory

Welcome to the Arctic Research website at the Chesapeake Biological Laboratory (CBL) of the University of Maryland Center for Environmental Science (UMCES). This website is meant to provide information about ecosystem and biogeochemical research in the Arctic, particularly the work of Jacqueline Grebmeier and Lee Cooper.

Our team at CBL includes faculty research associates Linton Beaven, Stephanie Soques, and Alicia Clarke, as well as, graduate students Chelsea Wegner, Christina Goethel and Laura Gemery. Alynne Bayard helps us with mapping our data using geographical information system technology (GIS). We also have an Associate Research Scientist associated with our research group, Cédric Magen, who provides expertise for day-to-day operation of CBL's stable isotope lab.

Distributed Biological Observatory (DBO) noaa dbo

One of the pressing needs for evaluating climate change impacts on biological systems in the Arctic (and globally) is the need for sustained observations of changes in biological systems. Biological observations cannot be automated to the same extent as many physical measurements can (e.g. salinity on moorings, etc.). As a result, there is much less scientific documentation of how biological systems are changing and/or adapting as a result of environmental change. We were involved in a science planning process supported by the National Oceanic and Atmospheric Administration, National Science Foundation, the international Pacific Arctic Group, and the International Arctic Science Committee, to initiate more systematic biological observations in the Pacific Arctic sector. This has evolved into the Distributed Biological Observatory (DBO) which takes advantage of increased multi-national interest in the larger Bering Strait region. Jackie Grebmeier (jgrebmei@umces.edu) is the key contact for this effort and further information on the DBO effort can be found at the DBO website, https://www.pmel.noaa.gov/dbo/.

Scientific results from the DBO project have been presented at a number of scientific meetings, including a special session at the 2018 Ocean Sciences Meeting that will be held in Portland, Oregon, USA from Feb 11-15, 2018. Submissions to a special issue of Deep-sea Research II on DBO scientific results are now underway.

The 4th DBO Data Meeting was held November 8-9, 2017 in Seattle, WA, USA.

Presentations from the 2017 4th Distributed Biological Observatory (DBO) Workshop as well as the 2014 Pacific Arctic Group (PAG) Meeting (http://pag.arcticportal.org/) are posted below:

Dr. Monika Kędra from the Institute of Oceanology, Polish Academy of Science, is an international collaborator in the DBO, working with Dr. Jackie Grebmeier on benthic taxonomic issues. She has prepared a benthic taxonomic portal for organisms collected in the Pacific Arctic region. To access the site, see: http://www.iopan.gda.pl/projects/DBO/
