Northern Gulf of Alaska LTER

Established in 2018 as one of the National Science Foundation‘s Long Term Ecological Research (LTER) sites, the Northern Gulf of Alaska (NGA) LTER program investigates the features, mechanisms, and processes that drive the production of the NGA ecosystem and foster its resilience. 

As a highly productive subarctic marine biome, the NGA supports a rich and diverse ecosystem sustaining one of the world’s largest commercial fisheries, as well as iconic species of seabirds and marine mammals.

The NGA LTER Program seeks to understand the capacity of the ecosystem’s ability to deal with climate change ‒ both long-term trends and changes in variability ‒ and to better understand the elements that may affect its resilience.
