title: Benthic macroinfaunal samples collected from the Canadian Coast Guard Ship (CCGS) Sir Wilfrid Laurier, Northern Bering Sea to Chukchi Sea, 2013

description: The Pacific sector of the Arctic Ocean is experiencing major reductions in seasonal sea ice extent and increases in sea surface temperatures. One of the key uncertainties in this region is how the marine ecosystem will respond to seasonal shifts in the timing of spring sea ice retreat and/or delays in fall sea ice formation. Variations in upper ocean water hydrography, planktonic production, pelagic-benthic coupling and sediment carbon cycling are all influenced by sea ice and temperature change. To more systematically track the broad biological response to sea ice retreat and associated environmental change, an international consortium of scientists have developed a coordinated “Distributed Biological Observatory” (DBO) that includes selected biological measurements at multiple trophic levels, along with satellite and mooring measurements. The DBO currently focuses on five regional biological “hotspot” locations along a latitudinal gradient that allows for consistent sampling and monitoring at five biologically productive locations across a latitudinal gradient: DBO 1 (SLIP)-south of St. Lawrence Island (SLI), DBO2 (Chirikov)-north of SLI, DBO3 (southern Chukchi Sea), DBO4-NE Chukchi Sea,and DBO5-Barrow Canyon. This dataset contains benthic macroinfaunal population level from sediment samples collected at each station for the CCGS Sir Wilfrid Laurier cruise-Leg 1 in 2013, identified by station number (#), Station name (Stn. Name), Date (mm/dd/yy), latitude (°N), longitude (°W), and station depth (m). The following macroinfaunal parameters were determined: abundance, wet weight biomass (gww/m2), dry weight biomass (gC/m2), and taxon type.

title: Marine Mammal Watch, Northern Bering Sea and Chukchi Sea, July, 2016

description: Marine mammal observations were recorded along-track from north of Dutch Harbor, Alaska in the Bering Sea (166.50 W, 53.90 N) northward to Barrow Canyon at the boundary of the Chukchi and Beaufort Seas (157.42 W, 71.18 N) aboard the Canadian Coast Guard Ship (CCGS) Sir Wilfrid Laurier, during a July, 2016 research cruise. Observations include individual mammal species identification and counts, ice-cover percent, sea state, visibility and weather. Marine Mammal Watch observations were made as part of the Distributed Biological Observatory (DBO) to more systematically track the broad biological response to sea ice retreat and associated environmental change. The spatially-explicit DBO network, five regional biological "hotspot" locations along a latitudinal gradient, is organized through the Pacific Arctic Group (PAG), an international collaboration sanctioned by the International Arctic Science Committee.

title: Marine Mammal sighting data from cruises in the Pacific Arctic, 2018, from Distributed Biological Observatory (DBO) Regions

description: The Pacific Arctic region (PAR) extends from the northern Bering Sea to the Arctic Ocean Basin, and it is experiencing major reductions in seasonal sea ice and increases in sea surface temperatures. Within the PAR, the northern Bering and Chukchi Seas are among the most productive marine ecosystems in the Arctic and are important carbon sinks and seasonal sources of organic materials. These recent shifts in seasonal sea ice cover are having profound consequences for seasonal phytoplankton production as well as to intimately linked higher trophic levels, including food harvested locally for subsistence. Key uncertainties remain as to how the marine ecosystem will respond to seasonal shifts in the timing of spring sea ice retreat and/or delays in fall sea ice formation. Productivity may change as sea ice declines and penetration of sunlight into open water increases, but the trajectory of changes to food web structure are unclear. Many organisms, from plankton to top predators are changing their distribution, migration and foraging patterns. A number of marine sites in the Pacific Arctic have high biomass, both in the water column and on the seafloor and are focused foraging points for apex predators. Several of these sites have been identified and re-occupied seasonally and interannually during multiple international cruises as part of the Distributed Biological Observatory (DBO) network. The DBO observational data documenting the importance of these ecosystem “hotspots” provide a growing marine time-series from the northern Bering Sea to Barrow Canyon at the boundary of the Chukchi and Beaufort seas, and across the Beaufort Sea to Amundsen Gulf. In US waters, these sites are DBO1 (south of St. Lawrence Island, DBO2 (Chirikov Basin north of SLI), DBO3 (southern Chukchi Sea), DBO4 (central Chukchi Sea), DBO5 (upper Barrow Canyon) , DBO6 (Beaufort Sea shelf break at ~152W). As part of DBO efforts, marine mammal visual detections have been obtained from any research voyage with an on-board observer and sightings within DBO regions 1-6 have been highlighted.
