Seth Danielson, a GWA Principal Investigator, embarked as a Principal Investigator on the Northern Gulf of Alaska Long Term Ecological Research (NGA-LTER) research cruise aboard the R/V Sikuliaq, April 18 – May 5, 2018. This cruise continues the sampling begun in fall 1997 under the NSF/NOAA NE Pacific GLOBEC program, and supported subsequently by a consortium of the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council’s (EVOSTC) Gulf Watch.

Seths’s focus is on the ‘motion of the ocean’, or the oceanographic processes that drive the NGA’s productivity and make it resilient. His work involves performing CTD measurements and bottle sampling to determine the thermohaline, velocity, light, and oxygen structure of the NGA shelf, in addition to its nutrient structure.
