December 11 - NOAA released the 2018 Arctic Report Card at the American Geophysical Union fall meeting in Washington, D.C today bringing together the work of 81 scientists from 12 nations to provide the latest in peer-reviewed, actionable environmental information on the current state of the Arctic environmental system relative to historical records.
The Arctic continued it long-term warming trend in 2018, warming at twice the rate relative to the rest of the globe with Arctic air temperatures for the past five years (2014-18) exceeding all previous records since 1900. Arctic sea ice in 2018 remained younger, thinner, and covered less area than in the past. The 12 lowest extents in the satellite record have occurred in the last 12 years. In the Bering Sea, winter sea ice extent reached a record low for virtually the entire 2017-2018 ice season, which typically begins to form at the beginning of October, expands through the winter and then melts through the spring. During two weeks in February, typically the height of winter, the Bering Sea lost significant ice cover, about ~215,000 km2 or about the size of Idaho. Ocean primary productivity levels in 2018 were sometimes 500% higher than normal levels in the Bering Sea which is linked to the record low sea ice extent in the region. The Bering Sea is an important commercial fishing region and supports a vibrant sea ice-ecosystem with abundant seals, birds, and other pelagic species that critically depend on the timing of sea ice formation and retreat.
Continued warming of the Arctic atmosphere and ocean are driving broad change in the environmental system in predicted and, also, unexpected ways. New emerging threats are taking form and highlighting the level of uncertainty in the breadth of environmental change that is to come.

This weekend, the EcoFOCI program completed its eleventh and final research cruise of its field season on the F/V Aquila to maintain and enhance an innovative array of biophysical moorings in conjunction with annual ship-based hydrographic data in the Bering Sea.
The team recovered 14 and deployed 10 moorings, including swapping the M2-site surface mooring for a sub-surface mooring to prevent damage from the ice to ensure 25 years of nearly continuous data. Scientists from PMEL, NOAA Fisheries Alaska Science Center and University of New Hampshire also collected some measurements from a CTD (conductivity-temperature-depth), nutrients, oxygen, plankton and larval fish along the Distributed Biological Observatory (DBO) Line 1, which has only been sampled once in 2017. These DBO lines are designated “hot spots” centered on locations of high productivity, biodiversity and rates of biological change in the Bering, Chukchi, and Beaufort seas.
Results from these observations and experiments will help describe important ecosystem linkages among climate, plankton, fishes, birds and mammals. Continuous monitoring from this region provides critical data to support sustainable management of living resources in the Bering Sea.
The EcoFOCI program is a collaborative research effort by scientists at the Pacific Marine Environmental Lab (PMEL) and Alaska Fisheries Science Center (AFSC) focusing on the unique and economically important high-latitude ecosystems of Alaska.
Congratulations to all involved with the 2016 Saildrone missions on receiving the Department of Commence Bronze Award and to Susie Snyder for receiving the NOAA Distinguished Career Award.
NOAA’s PMEL and Alaska Fisheries Science Center were awarded the Bronze Medal for “strengthening NMSF-OAR collaborations through the pioneering use of a Saildrone for next-generation ecosystem surveys in the Bering Sea”.
In 2016, the team successfully conducted the first ecosystem study using two Saildrones. The mission combined both physical and biological oceanography to seek out new ways to supplement traditional vessel-based research. The Saildrones each traveled almost 3,000 nautical miles in the 101 day mission testing innovative technologies, including a specially developed echo sounder and a modified whale acoustic hydrophone. Collectively, the oceanographic, meteorological, and fisheries measurements provided unique and groundbreaking insights to understanding the economically and culturally important ecosystem in the Bering Sea.
This was a collaborative mission between the NOAA’s Pacific Marine Environmental Lab, NOAA’s Alaska Fisheries Science Center, UW Joint Institute for the Study of the Atmosphere and Ocean, Saildrone Inc., Simrad AS/Kongsberg Maritime, Greeneridge Sciences Inc, and Wildlife Computers. Read more about the 2016 mission here.
The DOC Bronze Award is the highest honor award granted by the Under Secretary of Commerce for Oceans and Atmosphere, which recognizes superior performance characterized by outstanding or significant contributions, which have increased the efficiency and effectiveness of NOAA.
Susie Snyder was also awarded The Distinguished Career Award for her “continued efforts in improving budgetary policies and procedures relating to memorandum of agreements and reimbursable funds throughout 30 years of service to NOAA”. This award honors contributions on a sustained basis — a body of work — rather than a single, defined accomplishment. This award also recognizes significant accomplishments across all NOAA program areas and functions that have resulted in long- term benefits to the bureau’s mission and strategic goals.

After 60 days in the Bering Sea, the Oculus Coastal Glider was successfully recovered by crew of the NOAA Ship Oscar Dyson on September 26, 2017. The glider successfully navigated 242.8 nautical miles, completed 3612 dives, and sampled salinity, temperature, dissolved oxygen, sunlight, and fluorescence at a frequency of approximately 3 dives per hour. The glider was tested in a region with a long history of shipboard and mooring observations that provide context for the Oculus glider's observations. Oculus glider measurements reveal detailed information in a known, important biogeographical transition that divides the ecosystems of the northern and southern Bering Sea shelf near St. Matthew Island. Measurements show unexpected ocean mixing in the water column near the island that may be due to internal waves. Data, sensor, and platform analysis is ongoing. Incorporating this higher resolution sampling into the Bering Sea observing network will improve our understanding of how these features affect the ecosystem.
The Oculus is a coastal glider engineered to work in the highly stratified, shallow depths of the Arctic. By using a rapid buoyancy system, the glider can change buoyancy states 20 times faster and achieve speeds three times faster than legacy gliders - allowing for a more efficient and adaptive Arctic survey, but transferable to a variety of markets.
This was the second field test for the Oculus coastal gliders. The first field test occurred early May 2017, also in the Bering Sea, with 387 dives completed near the M2 mooring site. For the second field test, the glider was deployed from the US Coast Gaurd Cutter Healy during the 2017 Arctic Shield mission.
The Oculus was developed at PMEL in partnership with the University of Washington's Joint Institute for the Study of the Atmosphere and Ocean and the University of Washington Seaglider Fabrication Lab.
Over the next four months, NOAA scientists will launch unmanned ocean vehicles, called Saildrones, from the Arctic to the tropical Pacific Ocean to help better understand how changes in the ocean are affecting weather, climate, fisheries and marine mammals. The wind and solar-powered research vehicles that resemble a sailboat will travel thousands of miles across the ocean, reaching some areas never before surveyed with such specialized technology.
Earlier this week, PMEL scientists and Saildrone, Inc. sent off three saildrones from Dutch Harbor, Alaska. For the first time, two saildrones will sail north through the Bering Strait into the Arctic Ocean to study how the Arctic Ocean is absorbing carbon dioxide. A third unmanned vehicle will survey more than 3,100 nautical miles in the Bering Sea for walleye pollock, Northern fur seals that prey on them and the elusive North Pacific right whale. This work will build on research conducted during 2016, including a study of fur seal feeding rates. NOAA Fisheries Alaska Fisheries Science Center scientists will also attach video cameras to fur seals to record feeding and verify the species and sizes of fish that fur seals are eating.
In September, scientists will launch two more unmanned systems from Alameda, Calif., on a six-month, 8,000-nautical-mile, round-trip mission to the equator to improve the Tropical Pacific Observing System (TPOS). TPOS provides real-time data used by the U.S. and partner nations to forecast weather and climate, including El Nino. The unmanned sailing vehicles will take part in a larger field study with NASA, and visit mooring sites along the array of observing buoys.

The EcoFOCI spring mooring cruise departed on Earth Day, April 22, from Kodiak, AK to service a biophysical mooring array in the Bering Sea, including M2. This is one of 11 research cruises the program will participate in from March-October. Aboard the NOAA research ship Oscar Dyson, scientists from PMEL, JISAO and AFSC are in Alaskan waters to retrieve and redeploy moorings, collect CTD (conductivity-temperature-depth) and other data. Peter Proctor from PMEL/JISAO is the Chief Scientist on the cruise and Geoff Lebon is the lead mooring scientist. The M2 mooring has been deployed in the southeastern Bering Sea for over 20 years and has been providing year-round measurements of temperature, salinity, nitrite, chlorophyll, and currents in this highly productive area. Long-term time-series at this site are a critical tool for adapting to climate change and guiding sustainable management of living resources in the Bering Sea.
EcoFOCI will also be field testing and using several technologies in collaboration with PMEL’s Innovative Technology for Arctic Exploration program; including the Prawler, Oculus and Acrobat Towed Vehicle. These technologies enhance shipboard and mooring research with more data collection over a fine scale region.
The EcoFOCI program is a collaborative research effort by scientists at the Pacific Marine Environmental Lab (PMEL) and Alaska Fisheries Science Center (AFSC) focusing on the unique and economically important high-latitude ecosystems of Alaska. Learn more about the program here.
Last week, PMEL scientists attended the American Meteorological Society (AMS)’s Annual Meeting in Seattle, WA and the Alaska Marine Science Symposium (AMSS) in Anchorage, AK. Presentations covered research in the Bering Sea, data management and access, El Nino, sea ice, the Earth's energy imbalance, innovative technologies, and recent warming in the Pacific and others.
At AMSS, the Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) group had multiple presentations and posters on the Bering Sea including topics on the recent marine heat wave in Alaska, linking annual oceanographic processes to contiguous ecological domains in the pacific Arctic, fish distributions, ecology, Saildrone and oceanography.
A wider range of topics were covered at AMS and included invited talks from Nick Bond, Chidong Zhang and Kevin Wood. Dr. Zhang spoke about the Dynamics of the Madden-Julian Oscillation; Kevin Wood presented the Old Weather Project using historical U.S. ship logbooks to collect and analyze historical climate data; and Nick Bond discussed the recent warming in the NE Pacific. The annual meeting is the world’s largest yearly gathering for the weather, water, and climate community and brings together atmospheric scientists, professionals, students, educators and research’s from around the world. AMS is the nation’s premier scientific and professional organization promoting and disseminating information about the atmospheric, oceanic, hydrologic sciences.

NOAA Fisheries and its partners, including the Pacific Marine Environmental Laboratory, released Regional Action Plans (RAPs) on December 16th, to guide implementation of the NOAA Fisheries Climate Science Strategy in each region (Northeast, Southeast, Gulf of Mexico, Alaska, Western, Pacific Islands). Ecosystems and Fisheries Oceanography Coordinated Investigations (EcoFOCI) program lead Phyllis Stabeno (PMEL) and Janet Duffy-Anderson (AFSC) were co-authors on the Alaska Regional Report. The Alaska Fisheries Science Center and the Pacific Marine Environmental Laboratory have the scientific infrastructure needed to produce the analyses and deliver benchmarks for the eastern Bering Sea.
This Regional Action Plan identifies key actions to address priority information needs over the next five years to better understand, prepare for and respond to climate changes in the Bering Sea ecosystem. The Regional Action Plan, part of the NOAA Fisheries Climate Science Strategy, focuses on seven science objectives.
Alaska's fisheries are worth $1.8 billion and are vital to local economies and our country's food supply. Alaska is also at the front lines of a changing marine environment. To protect and maintain the region's resources, fishermen, lawmakers and other decision-makers need information to respond to these changes and protect livelihoods and traditional cultures.The Regional Action Plan will help Alaskan communities, commercial and recreational fishermen and others who are dependent on Alaskan marine resources respond and adapt to changes that may be ahead in response to a changing climate and help ensure the sustainability of these marine resources.
