NGA LTER Begins

LTER Logo

In March 2017, the College of Fisheries and Ocean Sciences and the University of Alaska Fairbanks announced that our Northern Gulf of Alaska research program (the Seward Line) would be joining the National Science Foundation’s Long Term Ecological Research (LTER) program. This is important recognition of 20 years of multidisciplinary oceanographic observations along the Seward Line and within Prince William Sound.

The LTER program networks (now) 28 individual research sites. LTER’s unique ecological investigations measure changes over years and decades in various environments. Each LTER site involves dozens of researchers and depends on partnerships with hosting entities like universities, national forests, or non-profit organizations. There are other LTER sites in Alaska: Bonanza Creek and Toolik Lake, and another new marine site in the Beaufort Lagoons.

Seward Line

The Seward Line is a long-term observational program on the Gulf of Alaska shelf. It was originally undertaken by the Northeast Pacific GLOBEC program from 1998–2004. During the years 2005–2009, sampling along the Seward Line continued with funding from the North Pacific Research Board. Most recently, funding has come from a consortium of NPRB, AOOS, and EVOS (see our Site History.)

The purpose of our research has been to develop an understanding of the response of this marine ecosystem to climate variability. Hence, the Seward Line cruises determine the physical and chemical oceanographic structure, the primary production, and the distribution and abundance of zooplankton. We then examine the seasonal and inter-annual variations in these measurements.

LTER -A New Partner

Having a new partner in the funding consortium will enable expansion of our program’s elements. For instance, a third annual cruise will be performed between the two cruises in May and September. In addition, we’ll be able to perform more in-depth experiments on the processes that enable the high productivity in the Northern Gulf of Alaska area. And finally, the LTER Network’s emphasis on education, outreach, and data availability will also encourage growth in these areas.
