Transient shifts in Bering Sea shelf phytoplankton size structure in response to wind‐induced mixing

JM Nielsen, Michael William Lomas, Lisa B. Eisner, Noel A. Pelland et autres

Abstract Phytoplankton community size structure is a key attribute that influences pelagic trophic energy transfer and the vertical flux of organic matter to benthic food webs. To capture the ephemeral scale of phytoplankton population size spectra we developed an approach, combining long‐term …

High‐Resolution Primary and Net Community Productivity Estimates in the Southeast Bering Sea From Moored Observations

Haley Cynar, L. W. Juranek, Noel A. Pelland, Jens M. Nielsen et autres

Abstract The Bering Sea is a highly productive subarctic ecosystem with some of the most valuable commercial fisheries in the United States. This seasonally ice‐covered sea has been rapidly changing due to ocean warming with impacts to the ecosystem structure and fisheries. …

Progress of Fisheries-Oceanography Coordinated Investigations in the Gulf of Alaska and Aleutian Passes

Calvin W. Mordy, Nicholas A. Bond, Edward D. Cokelet, Alison L. Deary et autres

Ecosystems & Fisheries-Oceanography Coordinated Investigations (EcoFOCI) is a joint research program between the NOAA Pacific Marine Environmental Laboratory and the Alaska Fisheries Science Center (AFSC). FOCI was established by NOAA in 1984 to study the variability in recruitment success of commercially valuable …

Advancing Observational Infrastructure in the Arctic

Scott E. Stalin, Shaun W. Bell, Nicholas Delich, Calvin W. Mordy et autres

Sampling under ice-covered seas, such as the Chukchi and Bering, is difficult. Vessels capable of working in ice are limited, ice destroys surface floats, and ice keels on the shallow Chukchi shelf can extend downward 30 m, confining subsurface moorings to the …

Long-Term Biophysical Observations and Climate Impacts in US Arctic Marine Ecosystems

Phyllis J. Stabeno, Shaun W. Bell, Catherine L. Berchok, Edward D. Cokelet et autres

In 1995, the first of a nearly continuous sequence of biophysical moorings was deployed at a site (M2) on the southeastern Bering Sea shelf. Over the next 15 years, 10 additional mooring sites were initiated. The resultant long-term biophysical mooring array extends …

Accelerating Research and Development in the US Arctic Reflections on a NOAA Program

Heather Tabisola, Calvin Calvin, Scott E. Stalin

Since 2015, the Innovative Technology for Arctic Exploration (ITAE) program has supported maritime technology development that contributes to economic growth, ocean health, and ocean management in Alaska. The program does this in multiple ways: through public-private partnerships, platform and small-scale sensor design, …

EcoFOCI: A Generation of Ecosystem Studies in Alaskan Waters

Heather Tabisola, Janet T. Duffy‐Anderson, Calvin W. Mordy, Phyllis J. Stabeno

Long-term monitoring and data collection provide the foundational knowledge and context for understanding how climate change impacts Alaskan marine ecosystems. A generation of ocean observing by the US National Oceanic and Atmospheric Administration (NOAA) Ecosystems and Fisheries Oceanography Coordinated Investigations (EcoFOCI) is …

Exploring the Pacific Arctic Seasonal Ice Zone With Saildrone USVs

A. M. Chiodi, Chidong Zhang, Edward D. Cokelet, Qiong Yang et autres

More high-quality, in situ observations of essential marine variables are needed over the seasonal ice zone to better understand Arctic (or Antarctic) weather, climate, and ecosystems. To better assess the potential for arrays of uncrewed surface vehicles (USVs) to provide such observations, …

Ocean Arc: An Ocean Shot for the Arctic

Heather Tabisola, Calvin W. Mordy, Brian S. Skerry, Christopher Meinig

Abstract Photography can be a powerful instrument for change. Combining scientific research, new imaging technologies equipped with Artificial Intelligence, and underwater photography, we'll share near- to real-time changes of biodiversity in the Arctic and highlight these rapidly changing and unique environments. Through …

Autonomous vehicle surveys indicate that flow reversals retain juvenile fishes in a highly advective high‐latitude ecosystem

Robert M. Levine, Alex De Robertis, Daniel Grünbaum, Rebecca A. Woodgate et autres

Abstract Summer surveys of the Chukchi Sea indicate that high densities of age‐0 gadid fishes, historically Arctic cod (Boreogadus saida) but recently also walleye pollock (Gadus chalcogrammus), dominate the pelagic fish community. Adults are comparatively scarce, suggesting that either overwinter survivorship of …
