2022 Field Season Comes to a Close

That’s a wrap on the 2022 NGA LTER field season! In late April the season started with a chilly expedition aboard the R/V Sikuliaq. Although storms battered our efforts, the weather cooperated enough for us to complete all of our sampling lines, as well as deployment of the Gulf of Alaska Ecosystem Observatory moorings. These moorings allow for collection of in-situ data.

The summer Sikuliaq cruise forged ahead, despite weather and COVID challenges. Scientists expanded upon regular grid sampling by conducting more in-depth examinations of the role of the Copper River’s freshwater input to the NGA. This included small-boat operations around the mouth of the Copper River.


The fall expedition aboard the R/V Tiglax began right on schedule. Luckily this was immediately after a major storm event passed through the Gulf. The science team was able to keep on pace, and completed all sampling along the Seward Line and into Prince William Sound.

Many fall cruise participants departed straight from the ship to meet colleagues at the 2022 LTER All Scientists’ Meeting. The meeting was held September 19-23 in Asilomar, CA. After a long time apart, it was great to join together with members from other LTER network sites.

Our NGA LTER team will gather again in Fairbanks in December. The goal will be to share recent findings, and plan ahead for 2023 and beyond.

NGA LTER Women in Oceanography Featured in Network Article

Western Washington University graduate student Megan O’Hara wrote an article for the LTER Communication Network, which was featured in November’s LTER Network News. The article Women in Oceanography: Highly Accomplished but Still Underrepresented features the NGA LTER‘s own Suzanne Strom, Kelley Bright and Ana Aguilar-Islas.

Megan is a master’s student studying phytoplankton in the NGA. Her thesis is titled “Cryptophytes in the Northern Gulf of Alaska: an analysis of distribution and regulation of mixotrophy.”
