Bering Ecosystem Study (BEST) and Bering Sea Integrated Ecosystem Research Program (BSIERP). We are involved in both the BEST (supported by the National Science Foundation) and BSIERP programs (supported by the North Pacific Research Board) starting in 2008. General information on these two linked programs is available at a web site supported by the North Pacific Research Board: http://bsierp.nprb.org/ Work on our portion of this project is now coming to a close. We report below our activities, as well as some educational outreach products that are available. These products include youtube videos, teacher research blogs, podcasts, and longer film and video clip projects that were filmed on the ship during the research effort.
Our efforts in 2008, 2009 and 2010 included the participation of our research team on three cruises of the USCGC Healy (March 2008; April-May 2008, and March 2009), two cruises of the Canadian Coast Guard Service Sir Wilfrid Laurier (July 2008, July 2010), and a cruise aboard USCGC Polar Sea in March 2010. We are studying the response of organisms that live in or on the sediments on the shallow sea floor of the continental shelf to the decline of seasonal sea ice. Warming water temperatures are leading to a northward migration of fish and other predators into the northern Bering Sea, where they are competing for some for some of the same food resources that walruses, gray whales, bearded seals, eiders and other ice-associated or ice-adapted animals use. These animals dive to the seafloor to feed on the rich benthic communities. As ice edge phytoplankton blooms become less prominent as the sea ice declines or retreats earlier in the spring, it is likely that the transport of rich organic materials to the shallow sea floor will be altered and the food web changed. We are studying the boundary of this south to north transition from a fish-dominated food web in the Bering Sea to a benthic dominated system in the north as our part of this much larger program that involves scientists from throughout the United States and other countries. Studies of the distributions of walruses in the Bering Sea in relation to food resources are part of our cooperative studies with other researchers as well as epibenthic surveys we undertook on cruises this year with an underwater video system.

In additon, some other educational and outreach products from prior work in the northern Bering Sea:
A local community resident of Savoonga, Alaska, Mr. Perry Pungowiyi, was also able to join us on cruises in 2006, 2007 and 2008 on Healy. A report of his 2006 cruise observations prepared for the local Saint Lawrence Island Yupik communities (Savoonga and Gambell) is available at this link.

Impacts of Climate change on the Eco-Systems and Chemistry of the Arctic Pacific Environment (ICESCAPE) is a NASA supported program we are participating in through a collaborative project with Dr. Karen Frey of Clark University. The title of our project is "The Potential Impacts of Sea Ice Decline and River Discharge Shifts on Biological Productivity in the Chukchi and Beaufort Seas"
Some of our efforts include measuring dissolved organic carbon in seawater and sea ice samples and using isotopic tracers to follow runoff in the North American Arctic. Other efforts have included making optical measurements beneath sea ice, which has shown high transmission of light through melt ponds (see abstract of paper published in Geophysical Research Letters). Field work was initiated in June 2010 using the USCGC Healy and a second cruise was in June-July 2011. Check the Icescapes blog for information on the sampling in 2011.
PacMars is a new rapid response effort to synthesize existing data and knowledge in the Arctic from St. Lawrence Island in the northern Bering Sea north into the Chukchi and Beaufort Seas. It is funded through the North Pacific Research Board's North Pacific Research Institute. The intent is to fast-track by mid-year 2013 a synthesis of existing knowledge and research gaps so that is will be available for federal agencies in designing appropriate future research programs. Serving stakeholder needs, including energy extraction and subsistence hunting are elements of this multi-investigator and multi-instiutional project that will also be guided by an advisory panel with representation from many government agencies. This is obviously an ambitious undertaking, but a talented team from many institutions and scientific backgrounds has been assembled to undertake this work. Lee Cooper and Jackie Grebmeier are jointly leading the overall effort. A separate PacMARS website has been constructed to provide information on the project.
RUSALCA is a NOAA-sponsored program to document the long-term ecosystem health of the Pacific Arctic Ecosystem, particularly as changes are observed in climate forcing. A centerpoint of the work are periodic research cruises that visit both US and Russian waters to provide for comprehensive sampling irrespective of political or exclusive economic zone boundaries. Our work is particularly focused on benthic biological communities and associated sediment chemistry. Work by researchers at other US and Russian institutions is studying other components of the ecosystem. Some of our findings from the 2004 cruise that show decadal changes in organic carbon processing have been published in Deep-Sea Research II (see http://dx.doi.org/10.1016/j.dsr2.2008.10.025)
The most recent full-scale ecosystem cruises were in September 2009 and September 2012 in the Chukchi Sea aboard the M/V Professor Khromov, with University of Maryland participants Jackie Grebmeier, Monika Kedra and educator Betty Carvellas. Reports from the cruise on research activities and photos are available for both the 2009 and 2012 cruises through NOAA's Ocean Exploration program. The Reuters News Agency also reported/blogged from the ship in 2009. Betty Carvellas has provided a blog of research activities, including images of the research effort in both 2009 and in 2012, under the umbrella of the PolarTREC teacher program.

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 have been 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 as part of a Distributed Biological Observatory, DBO http://www.arctic.noaa.gov/dbo/, taking advantage of increased multi-national interest in the larger Bering Strait region. A workshop held in Seattle in May 2009, a town hall forum at the 2010 Ocean Sciences Meeting in Portland Oregon, and the feature article published in EOS, (the Transactions of the American Geophysical Society) on May 4, 2010 are part of the larger initiative. In 2011 two DBO open science community workshops were held, one during Arctic Science Summit Week in Seoul, Korea (March) and prior to the fall Pacific Arctic Group meeting in Sidney, BC, Canada (November); see workshop reports at http://pag.arcticportal.org/. A DBO pilot field program was held during 2010-2012, with multiple cruises occupying two DBO stations and transect lines in the SE Chukchi Sea and Barrow Canyon (see preliminary results at the DBO website). Jackie Grebmeier is the key contact for this effort (email address and other contact coordinates at top of page) and further information on the DBO effort can be found at the DBO website, http://www.arctic.noaa.gov/dbo/.
The DBO effort for improving observations of the changing Arctic ecosystem has grown in attention among several US federal agencies. The concept is being incorporated into the Strategic Action Plan for "Changing Conditions in the Arctic" that is an objective of the National Ocean Council's effort for formulation of a National Ocean Policy for the United States, as directed by President Obama.
Findings from the DBO effort were recently presented as part of the 2011 NOAA Arctic Report Card, pg. 84-87 ( in an essay entitled "Marine Ecology: Biological Responses to Changing Sea Ice and Hydrographic Conditions in the Pacific Arctic Region" and the 2012 Arctic Report Card highlights international efforts in the Barrow submarine canyon. Also, a 2012 paper on biological change observations in the Pacific sector by Jackie Grebmeier, entitled "Shifting Patterns of Life in the Pacific Arctic and Sub-Arctic Seas", is available as a free .pdf download from the Annual Review of Marine Science 4: 63-78, at:
Coverage of the Distributed Biological Observatory concept also aired on the Alaska Public Radio Nework on April 14, 2011 (download the .mp3 file).
With support from the National Science Foundation, we are moving forward in 2013 with the DBO concept as a project incorporated into the Arctic Observing Network. Our work will be from aboard the Canadian Coast Guard vessel Sir Wilfrid Laurier and will continue annual long-term water column and benthic sampling through 2017, together with efforts to coordinate international sampling in areas of biological interest in the Bering and Chukchi Seas. The project summary of the proposal to support this effort is hosted on a National Science Foundation webpage and the work includes collaborators Bob Pickart (Woods Hole) and Karen Frey (Clark University).
