Journal ArticleDOI
The transition zone chlorophyll front, a dynamic global feature defining migration and forage habitat for marine resources
TL;DR: In this paper, a transition zone chlorophyll front (TZCF) was observed to have a strong influence on the spatial distribution of loggerhead turtles and albacore tuna in the North Pacific.
Journal ArticleDOI
Turtles on the edge: movement of loggerhead turtles (Caretta caretta) along oceanic fronts, spanning longline fishing grounds in the central North Pacific, 1997–1998
TL;DR: In this article, the authors tracked nine juvenile loggerhead sea turtles tracked during 1997 and 1998 in the central North Pacific by satellite telemetry all travelled westward, against prevailing currents, along two convergent fronts identified by satellite remotely sensed data on sea surface temperature (SST), chlorophyll and geostrophic currents.
Journal ArticleDOI
TurtleWatch: A tool to aid in the bycatch reduction of loggerhead turtles Caretta caretta in the Hawaii-based pelagic longline fishery
TL;DR: In the first quarter of each calendar year from 1994 to 2006, the majority of shallow longline sets and associated loggerhead turtle bycatch were above 28° N, which corresponds to the area near the North Pacific Subtropical Frontal Zone as mentioned in this paper.
Journal ArticleDOI
Reducing sea turtle interactions in the Hawaii-based longline swordfish fishery
Eric Gilman,Eric Gilman,Donald R. Kobayashi,Donald R. Kobayashi,Tom Swenarton,Paul Dalzell,Irene Kinan-Kelly +6 more
TL;DR: There was no significant correlation between turtle and swordfish catch rates (vessels with high swordfish CPUE do not necessarily have high turtle CPUE), indicating that there may be a fishing practice or gear design causing some vessels to have low turtle catch rates without compromising sword fish catch rates.

TL;DR: In this article, a modified version of a productivity and susceptibility analysis (PSA) is used to evaluate the vulnerability of stocks to fishing practices in U.S. federal waters.
