A key question is how the marine e cosystem will respond to these rapid environmental shifts. Variations in u pper-ocean water hydrography\, stratification\, light penetration\, plankt onic production\, pelagic-benthic coupling and sediment carbon cycling are all influenced by sea ice and temperature changes. To evaluate these resp onses\, the Distributed Biological Observatory (DBO) was initiated in 2010 as a change detection array for the identification and consistent monitor ing of biophysical responses to environmental change in the Arctic.  The e cological trends approach embedded in DBO sampling is facilitated by repea ted sampling each year through multiple international occupations of agree d-to transect lines\, along with more continuous data collections obtained through mooring and satellite observations. This presentation will provid e an overview of key results observed during multiple cruises that have be en part of the DBO effort. In particular\, biological changes in the north ern Bering Sea resulting from the dramatic reduction in winter sea ice and warming seawater since 2018 are being linked to changes in the sediment-b ased prey for diving seaducks\, walruses\, gray whales\, and bottom-feedin g fish.\n\n\n\nShort Biography:  Jacqueline Grebmeier is a Research Profes sor at the University of Maryland Center for Environmental Sciences\, Ches apeake Biological Laboratory (CBL). She received an undergraduate degree ( B.A.) in Zoology from the University of California\, Davis in 1977\, a Mas ter’s (M.S.) degree in Biology from Stanford University in 1979\, and a se cond M.S. degree in Marine Affairs from the University of Washington in 19 83. She received a Ph.D. in Biological Oceanography from the University of Alaska Fairbanks in 1987. Following an appointment as a postdoctoral asso ciate at the University of Southern California from 1987-1988\, she affili ated with the University of Tennessee in 1989 until she began her current position at CBL in 2008. Her oceanographic research interests are related to pelagic-benthic coupling\, benthic carbon cycling\, and benthic faunal population structure in relation to ecosystem structure in polar marine sy stems. She has participated in more than 55 field research cruises\, prima rily in the Arctic. She served as project director and chief scientist for the US National Science Foundation (NSF) and Office of Naval Research sup ported Shelf-Basin Interactions field research program in the Beaufort and Chukchi Seas from 1999-2007. In addition\, she was involved in the Russia n-American Long-term Census of the Arctic (RUSALCA)\, supported by the US National Oceanic and Atmospheric Administration (NOAA) and the Chukchi Sea Offshore Monitoring in Drilling Area (COMIDA) program\, supported by the US Bureau of Ocean Energy Management (BOEM)\, the Bering Sea Program\, sup ported by NSF and the North Pacific Research Board\, and the international ly coordinated Distributed Biological Observatory (DBO) in the Arctic\, su pported by multiple agencies in the US and international collaborators in the Pacific Arctic Group. She has served on multiple advisory and review c ommittees to the U.S. National Academy of Sciences (NAS)/Polar Research Bo ard\, NSF\, NOAA\, BOEM\, and Fish and Wildlife Service\, along with inter national boards. She was appointed by President Clinton to the US Arctic R esearch Commission from 2000-2003 and she served as the US delegate and on e of four Vice-Presidents to the International Arctic Science Committee (I ASC) from 2006-2014. She has led the international DBO program since 2010 in the Pacific Arctic\, which is a network of international collaborators who study ecosystem change and associated drivers in the Arctic. She has r eceived multiple awards\, including the Alaska Ocean Leadership Award from the Alaska SeaLife Center in 2015\, the IASC Medal in 2015\, the Universi ty of Maryland Center for Environmental Sciences President’s Award for Exc ellence in Application of Science in 2017\, and she was elected a fellow o f the American Association for the Advancement of Science in 2018.
