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.

PMEL scientists, including scientists from the University of Washington's Joint Institute for the Study of the Ocean and Atmosphere (JISAO) and Oregon State University's Cooperative Institute for Marine Resources Studies (CIMRS) are attending the American Geophysical Union (AGU)’s Annual Meeting in San Francisco this week, December 12-16. AGU's Falling Meeting is the largest Earth and space science meeting in the world bringing together the Earth and space science community for discussions of emerging trends and the latest research. Poster and talk topics include data integration, El Nino Southern Oscillation (ENSO), Indian Ocean temperature trends, hydrothermal plumes and vents, carbon dioxide in the tropics and Gulf of Alaska, aerosol research, and heat impacts on marine ecosystems and fisheries, tsunamis, and acoustic research.
The 2016 Arctic Report Card will be released Tuesday morning in conjunction with a press conference led by NOAA’s Jeremy Mathis. The 2016 Arctic Report Card brings together the work of 61 scientists from 11 nations to provide the latest information on multiple measures of Arctic environmental change, including air and sea surface temperature, sea ice, snow cover, vegetation, wildlife, and plankton abundance. Read the full report and highlights here as well as the press release. Watch the recorded press conference here.
Researchers will also present during a press conference Thursday morning some of the first scientific results from the 2015 Axial Seamount eruption including discoveries of previously unknown structures and new glimpses into the volcano’s internal plumbing. These new insights into the world’s most active and well-studied underwater volcano may help scientists better understand all volcanoes and the hazards they pose. Read the press release here.

Dr. Bob Embley from the Earth-Ocean Interactions group will be honored during the Awards Ceremony as part of the 2016 class of Fellows for his pioneering contributions to the understanding of deep-sea volcanism by fostering interdisciplinary investigations with advanced technologies.
In the summers of 2008–2010, Dr. Ned Cokelet added rugged instruments to NOAA bottom trawl survey nets on the eastern Bering Sea continental shelf – site of the nation’s most productive fisheries – to measure ocean temperature and salinity at over 350 locations. The results, released in Deep Sea Research II, provide the most comprehensive view to date of the three-dimensional thermohaline structure. Horizontal variations of the ocean’s mass density, computed from the temperature and salinity measurements, give the ocean currents shown by arrows in the accompanying figure for summer 2010. The flow was strongest west of the Pribilof and St. Matthew Islands, and there was clockwise circulation around St. Matthew Island. The upper layer of the ocean was mixed down to less than 30 m over much of the region, but reached depths greater than 70 m along the Alaska Peninsula. Upper-to-lower layer salinity differences contributed more than temperature to density differences over most of the region. These observations enhance our understanding of plankton and fish-larval transport and can serve to calibrate predictive computer models of the ecosystem.

September 10 – 20: The Arctic Heat Team has been making their way from Barrow, AK to Kotzebue on a specially-outfitted NOAA Twin Otter aircraft. Over the 10 day mission, the team is launching traditional atmospheric and oceanographic probes as well as the experimental Air-Launched Autonomous Micro-Observer (ALAMO) floats into the Chukchi Sea. Four ALAMO floats were deployed in June 2016 in the Chukchi and Beaufort Seas. These floats will continue to collect data on upper ocean temperatures throughout the year.
The team on this mission includes: Kevin Wood and Nick Bond from UW/JISAO and NOAA/PMEL, Woods Hole Oceanographic Institution’s engineer Alex Ekholm, and LTJG Kevin Doremus as the Aircraft Commander.

On September 3, after three months of collecting data in the Bering Sea, the two Saildrones have been safely recovered. The Saildrones each traveled almost 3000 nautical miles in 101 days. After arriving in Dutch Harbor, AK, the Saildrones were packed into a container and shipped to their home base in San Francisco, CA. Data from the tested technologies for fish and marine mammal acoustics are expected mid-September with preliminary analysis completed around the New Year.
This was a collaborative mission between the Pacific Marine Environmental Lab, Alaska Fisheries Science Center, Saildrone, Inc., Simrad AS/Kongsberg Maritime, Greeneridge Sciences, Inc, and Wildlife Computers.

PMEL scientists from the Ecosystems and Fisheries Oceanography Coordinated Investigations (EcoFOCI) program attended the first Principal Investigator meeting for the North Pacific Research Board (NPRB)’s five-year Arctic Integrated Ecosystem Research Program (Arctic IERP) in Anchorage, Alaska on June 20-23.
This historic Arctic Integrated Ecosystem Research Program will study the northern Bering and Chukchi Seas during spring through fall to better understand how changes in physical environmental drivers influence the structure and function of the biological system and access to subsistence resources. The EcoFOCI team (comprised of PMEL, AFSC, JISAO, and Bigelow Laboratory scientists) will lead the Oceanography and Lower Trophic Level Productivity portion of the program under the direction of Carol Ladd. The field seasons for this project are planned to begin in spring 2017 through the fall of 2019.
The goals of the meeting were to introduce the funded projects, discuss how these projects are connected, identify any gaps, come to a consensus on the overarching hypothesis for the integrated research, introduce PI's from other Arctic projects that may integrate with the Arctic IERP research, and discuss the framework for integration, data management, and communication/outreach during the project.
This summer, NOAA’s Pacific Marine Environmental Lab is mentoring six undergraduate Hollings scholars and one NSF research experience for undergraduates (REU) student. These students come from all over the United States and all have a passion for the marine environment.
