The California Current System (CCS) is a highly productive eastern boundary upwelling system. Cross-shore transport driven by horizontal stirring from mesoscale (and submesoscale) eddies, fronts, and filaments, which shift surface productivity away the narrow zone inshore. Using an unprecedented 25-year daily record of finite size Lyapunov exponents (FSLEs), we characterize spatial temporal pat...

Water column currents and bottom temperature from September 2005 to 2006 across the narrow shelf region off Port Edward on east coast of South Africa, combined with satellite observations, highlighted dominant influence Agulhas Current (AC) circulation. Stronger southwestward flow occurred during austral summer autumn suggesting an intensification shoreward movement AC these seasons. In situ mo...

Since 2011, the mean number of bites per year by bull sharks Carcharhinus leucas has increased markedly at Réunion Island. To predict areas and periods risk, we need to better understand space-use dynamics individual sharks. In coastal waters off Island, two sharks, one each sex, were double-tagged tracked for 174 days (male) 139 (female) using pop-up satellite archival tags (PSATs) acoustic tr...

STOCK DEFINITION AND GEOGRAPHIC RANGE The northern Gulf of Mexico (i.e., U.S. Gulf of Mexico) continental shelf bottlenose dolphin stock inhabits waters from 20 to 200 m deep in the northern Gulf from the U.S.-Mexican border to the Florida Keys (Figure 1). Both “coastal” and “offshore” ecotypes of bottlenose dolphins occur in the Gulf of Mexico (Hersh and Duffield 1990; LeDuc and Curry 1998). T...
