NOAA has led, for 27 years, a team of international scientists in issuing annual reports on the state of the climate focusing on the year just passed. The State of the Climate in 2016 report, published as a supplement to Bulletin of the American Meteorological Society in August 2017, is the most recent release of this report. Seven Federal, JISAO (Joint Institute for the Study of the Atmosphere and Ocean, University of Washington), and JIMAR (Joint Institute for Marine and Atmospheric Research, University of Hawaii) scientists resident at PMEL co-authored four of twelve sections in the... more »

Wangen (2017): Advances in ecosystem research: Saildrone surveys of oceanography, fish and marine mammals in the Bering Sea. Oceanography, 30, 2, doi:10.5670/oceanog.2017.230.
This month's featured article provides an overview of the first Saildrone mission conducted jointly between NOAA Fisheries Alaska Fisheries Science Center (AFSC) and Pacific Marine Environmental Laboratory (PMEL).
The Saildrone is an autonomous surface vehicle outfitted with meteorological and oceanographic sensors, including passive and active acoustics. In 2016, NOAA used the Saildrone to survey the Bering Sea, a region known for its harsh conditions (e.g., storms, low light, biofouling) and high level of biological productivity. The mission was a success, and the Saildrone proved... more »
Figure 3.6(a): Time series of annual average global integrals of in situ estimates of upper (0–700 m) OHCA (1 ZJ = 10²¹ J) for 1993–2015 with standard errors of the mean.
Every year NOAA leads a team of international scientists in issuing a report on the state of the climate in the year just passed, published as a supplement to Bulletin of the American Meteorological Society. Nine Federal, JISAO, and JIMAR scientists resident at PMEL co-authored four of twelve sections in the Global Oceans chapter and one section in the Arctic chapter for the State of the Climate in 2015 report, published in July 2016. In addition, Dr. Gregory Johnson served as lead editor of the Global Oceans chapter and participated in the media roll-out event.

Studying where some of the smallest organisms in the ocean are located can be difficult when they are found beneath the surface. In the late summer and early fall, phytoplankton in the Chukchi Sea are usually found in thin, patchy layers that can only be observed using shipboard surveys. In a collaborative effort between PMEL’s EcoFOCI group and the University of Alaska Fairbanks, scientists were able to map the distribution of subsurface phytoplankton using a novel high-resolution towed instrument platform. A significant fraction of the phytoplankton biomass is contained in these layers,... more »
Overland, J.E. (2016): Is the melting Arctic changing mid-latitude weather? Phys. Today, 69(3), 38–43, doi: 10.1063/PT.3.3107.
According to model simulations, a warming Arctic can shift the circulation patterns of the polar jet stream and bring frigid air southward. But has it?
Since the 1980's the Arctic’s temperature rose at a rate more than double that of the Northern Hemisphere average—a relative increase referred to as Arctic amplification. Thinning sea ice, retreating glaciers, thawing permafrost, and greening tundra are among the numerous trends that are apparent in today’s Arctic.
Arctic warming may be responsible for another kind of severe weather: bouts of abnormally cold weather a thousand... more »
