The deployment of electronic data storage tags that are surgically implanted or satellite-linked provides marine researchers with new ways to examine the movements, environmental preferences, and physiology of pelagic vertebrates. We report the results obtained from tagging of Atlantic bluefin tuna with implantable archival and pop-up satellite archival(More)
Electronic tags were used to examine the biology of Atlantic bluefin tuna (Thunnus thynnus L.) on their breeding grounds in the Gulf of Mexico (GOM). The hypothesis that movement patterns, diving behavior, and thermal biology change during different stages of the breeding migration was tested. Mature Atlantic bluefin tuna tagged in the western Atlantic and(More)
The Tanana River hydrokinetic characterization study started in 2009, when little was known about how river environments in Alaska would affect hydrokinetic power generating devices or how those devices might affect the state's river environments. Few hydrokinetic devices were beyond the concept/design stage, and a first attempt at demonstrating a(More)
Polar cod (Boreogadus saida) is an important link between top predators and lower trophic levels in high-latitude marine ecosystems. Previous findings describe differences in its diet throughout the western Arctic; however, the causes of this variation are not well known. This study examined the diets of juvenile polar cod collected via demersal trawling(More)

Pop-up satellite archival tags were attached to 35 Atlantic bluefin tuna (Thunnus thynnus) off the New Eng-land coast of the United States of America in 1998, 2000, and 2001. The tags provided information on the horizontal and vertical movements and environmental preferences of bluefin tuna. Fish showed movement patterns that can be categorized by age and(More)
2 Executive Summary ORPC Alaska, LLC is developing a site in the Tanana River near Nenana, Alaska for testing their RivGen™ Power System. As part of the permitting requirements, it is necessary to conduct baseline fish distribution studies to assess potential interactions between the fishes and the turbine which may result if down-migrating juvenile fishes(More)
Testing pop-up satellite tags as a tool for identifying critical habitat for Pacific halibut (Hippoglossus stenolepis) in the Gulf of Alaska Restoration Project 01478 Final Report Study History: This project began with acceptance of the 2-year study plan by the Trustee Council in FY 2000. The funds were provided to test a new technology, pop-up satellite(More)
Animal telemetry is the science of elucidating the movements and behavior of animals in relation to their environment or habitat. Here, we focus on telemetry of aquatic species (marine mammals, sharks, fish, sea birds and turtles) and so are concerned with animal movements and behavior as they move through and above the world’s oceans, coastal rivers,(More)
