About

PAG: Pacific Arctic Group

"The Pacific Arctic Group (PAG) is a group of institutes and individuals having a Pacific perspective on Arctic science. Organized under the International Arctic Science Committee (IASC), the PAG has as its mission to serve as a Pacific Arctic regional partnership to plan, coordinate, and collaborate on science activities of mutual interest. The four PAG principle science themes are climate, contaminants, human dimensions and structure and function of Arctic ecosystems."

Marine Ecosystem Collaboration Team (MECT)

"The theme of the MECT is increasing understanding of the structure and function of Arctic marine ecosystems and their role in the climate system and advancing predictive capabilities. The DBO has activities under the MECT umbrella of objectives with cross-agency support."

NASA DBO Satellite Visualization Products

"In support of the NOAA Arctic Research Program Distributed Biological Observatory (DBO), which is a multi-agency program in the Arctic, color images of daily and weekly satellite data are provided together with time series animation of the key variables. The data presented are weekly averages of most recent data for the following: (1) Chlorophyll Pigment Concentration; (2) Sea Surface Temperature (SST); (3) Sea Ice Concentration; (4) Cloud Fraction; (5) Winds and Sea Level Pressure (SLP); (6) Sea Surface Salinity (SSS); and (7) Sea Surface Height Anomaly (SSHA). Chlorophyll, SST, and cloud data are from MODIS while sea ice concentration data are from SSM/I and winds and SLP data are from NCEP reanalysis. SSS nine-day average is from SMOS, and the SSHA is from Jason-2. Also presented are animations of running averages of weekly chlorophyll pigment concentration, daily surface temperatures using Reynolds SST data and daily ice concentration with NCEP winds. The five boxes in the images are the DBO study sites. If you are interested in seeing more imagery or obtaining the historical data, please contact Josefino Comiso (josefino.c.comiso@nasa.gov) for further information."

RUSALCA: Russian-American Long-term Census of the Arctic

"July 23, 2004 marked an historic day in Arctic research and exploration as well as Russian-U.S. relations. On this date the Russian research ship, the Professor Khromov, left Vladivostok, Russia packed with U.S.and Russian, funded scientists to begin a 45-day collaborative journey of exploration and research in the Arctic. Stemming from a 2003 Memorandum of Understanding for World Ocean and Polar Regions Studies between NOAA and the Russian Academy of Sciences, this cruise was the first activity under the Russian-American Long-term Census of the Arctic (RUSALCA). RUSALCA means mermaid in the Russian language. In November 2003, a RUSALCA planning workshop was held in Moscow, Russia to outline the biological, geological, chemical and physical oceanographic sampling strategies to be pursued in the Bering Strait and the Chukchi Sea."

Institute of Oceanology Polish Academy of Sciences: DBO benthic species

"Bering and Chukchi Seas, in Pacific Arctic sector, are one of the most productive systems in the world's ocean. Due to tight benthic pelagic coupling in these relatively shallow areas benthic fauna is highly abundant, reaches high biomass and plays important role as food items for higher trophic levels. These benthic driven areas are under strong impact of climate change, which includes dramatic seasonal retreats and thinning of sea ice, record-setting seawater temperatures and increased input of Pacific waters. The 'Distributed Biological Observatory (DBO)' initiative is envisioned as a change detection array along a latitudinal gradient extending from the northern Bering Sea to the Barrow Arc in the Chukchi Sea, in regional 'hotspot' transect lines and stations considered to exhibit high productivity, biodiversity, and overall rates of change."
