NOAA’s Pacific Marine Environmental Lab and Paul G. Allen Philanthropies have teamed up in a groundbreaking partnership to expand Deep Argo ocean observations to improve our understanding of weather, climate and potential improve prediction of sea level rise. Deep Argo expands on the success of the Argo array but will dive up to 6,000 meters or 3.7 miles to collect data on temperature and salinity up in the lesser understood bottom half of the ocean.
“Putting Deep Argo floats in the western South Atlantic is another step toward a global Deep Argo array, which will illuminate key portions of our changing oceans,” said Gregory C. Johnson, PMEL oceanographer who will lead the project. “It’s like we’ve had a candle in a dark room and now we’re going to flip on the lamp. We’ll see all the details.”
Paul G. Allen Philanthropies has committed more than $4 million for the multi-year project, Jump-Starting Deep Argo. Allen’s research vessel R/V Petrel will deploy an array of these floats in the deep international waters east of Brazil. PMEL will provide scientific expertise and ongoing support of the array.

Taylor Shellfish Farm’s Quilcene hatchery perches on a narrow peninsula that juts into the sinuous waterways of Washington’s Puget Sound. On the July day I visited, the hatchery and everything surrounding it seemed to drip with fecundity. Clouds banked over darkly forested hills on the opposite...
The Alaska Marine Highway System ferry Columbia will be part of an international science experiment starting this fall when it resumes its weekly run between Bellingham, Wash., and Southeast Alaska.
Washington’s hottest August on record worsened precipitation deficits, leading to more than half the state being classified Thursday as in “moderate drought,” according to climatologists.

A Saildrone departs Dutch Harbor, AK in 2016 on it's way to test sensors on this platform for multi-disciplinary science
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,... more
