This study examines the potential impact of future anthropogenic global warming on the Gulf of Mexico. The potential implications of the reduced warming in the northern Gulf of Mexico on pelagic fish species and their spawning patterns are discussed.

The Magnuson-Stevens Fishery Conservation and Management Act (MSFCMA) mandates NOAA to identify habitats essential for managed species and conserve habitats from adverse effects on those habitats. To meet these mandates, NOAA’s research must identify habitats that contribute most to the survival, growth and productivity of managed fish species and determine science-based measures to best manage and conserve these habitats from adverse effects of human activities. The NOAA Essential Fish Habitat Research Implementation Plan (AFSC 2006) for Alaska guided research to meet EFH mandates in Alaska during the last several years. This document revises and supersedes the initial Implementation Plan (AFSC 2006), and similar to the first plan is expected to guide the next several years of EFH research. The revision process began with a coordination meeting between Alaska Region habitat managers and Alaska Fisheries Science Center (AFSC) habitat scientists to determine the scope of the revised EFH research plan with a smaller group of 11 AFSC and Alaska Region staff subsequently completing the revision.

Multivariate statistical techniques were used to characterize temporal and spatial changes in abundances of the larvae of 20 common fish families from the early 1980s through to the late 2000s. The larvae of some pelagic and mesopelagic families showed marked increases in abundance over the survey time period, while the abundances of some benthic families decreased.

We used longline surveys to quantify the shark assemblage at French Frigate Shoals (FFS) atoll from May to August 2009. Fishing effort consisted of 189 longline sets totaling 6,862 hook hours of soak time.

We equipped individual tiger (Galeocerdo cuvier Péron and Lesueur, 1822) and Galapagos (Carcharhinus galapagensis Snodgrass and Heller, 1905) sharks with both acoustic and satellite transmitters to quantify their long-term movements in the Papahanaumokuakea Marine National Monument (Northwestern Hawaiian Islands).

We are collecting data and investigating the potential environmental impacts of the upcoming Elwha River dams removal.
