Dear PAG members

Our Distributed Biological Observatory (DBO) requested session was approved for the 2018 Ocean Sciences Meeting to be held in Portland, Oregon, USA from Feb 11-15, 2018. If interested, please consider submitting an abstract for that session and the submission deadline is Sept. 6, 2017. The Session ID is 28168 entitled "HE013-The Distributed Biological Observatory: An Expanding Change Detection Array in the Marine Arctic". Below is the session description:

Session Description:

Arctic marginal seas are undergoing historically unprecedented reductions in sea ice volume and extent, concomitant with increasing ocean temperatures. It is uncertain how the marine ecosystem is responding to these sea ice thinning trends and alterations in the timing of seasonal sea ice retreat and formation. The scope of these possible changes include primary production, planktonic and benthic biomass, migration patterns of upper trophic level consumers, and overall biogeochemical cycling. In order to systematically track biological responses to sea ice loss and associated environmental changes, an international consortium of scientists have developed the "Distributed Biological Observatory" (DBO), which integrates biological measurements at multiple trophic levels with physical oceanographic sampling from ships, satellites and moorings. The DBO initially focused on five biological "hotspot" regions distributed along a latitudinal gradient extending from the northern Bering Sea through the Chukchi Sea; subsequently, three DBO regions were added in the Beaufort Sea. An Atlantic-DBO, comprised of five transect lines, is now being developed in the northern Barents Sea and Fram Strait, and DBO lines have been proposed for Baffin Bay. This session will provide a forum to present recent multi-disciplinary scientific findings associated with physical forcing and ecosystem response detected through the DBO change detection array in the Pacific Arctic.

We hope you can join us at the DBO session. 

Thank you.
