Cobertura Geográfica
The geographic coverage includes the Patagonian shelf, from the edge of the Patagonian shelf and to the Argentine Basin in the SW Atlantic Ocean, and South Pacific area. Mixed subtropical-subpolar waters characterize five oceanographic regimes in terms of water masses, currents and productivity. 1) Open continental shelf waters of subantarctic origin. 2) Shelf break front a narrow transition region between subpolar (Malvinas/Falkland Current) and shelf waters. 3) Subtropical waters carried by the Brazil Current collide with the cold-fresh subpolar waters of the Malvinas Current. It is characterized by enhanced meridional gradients of sea surface temperature and salinity, and its location has high seasonal and interannual variability. 4) Subpolar characterized by low salinity, cold temperatures and high concentrations of nutrients. 5) Polar with low temperature (<4 °C) and relatively high nutrient concentration waters derived from the Antarctic Circumpolar Current.

Métodos de Amostragem
Satellite tags (SPOT4/SPOT5, Wildlife Computers, Redmond, Washington, http://www.wildlifecomputers.com) were deployed on juveniles southern elephant seals, during haul out at Península Valdés, Patagonia, Argentina. Tags were configured to send information through Argos System as soon as the animals entered the water.
| Área de Estudo | Records coverage the positions at sea during the foraging pelagic trip that includes the Patagonian shelf, from the edge of the Patagonian shelf and to the Argentine Basin in the SW Atlantic Ocean, and South Pacific area. Most of the records of each animal are one trip from and to Peninula Valdes. Each location was provided by the Argos System (http://www.cls.fr) and the frequency depended of the behavior of elephant seals at sea and their time surface intervals. |
|---|---|
| Controle de Qualidade | The behavior of elephant seals at sea and their short surface intervals precludes high accuracy with position fixes. An filter was applied to reject records that would require a travel rate greater than 2.8 m/s (10 km/h). |
Descrição dos passos do método:
- Instruments (Wildlife Computers, Redmond, Washington; instrument description at: http://www.wildlifecomputers.com.) were glued directly on the fur of the head using a 10-min setting epoxy resin (Campagna et al., 1999). Anesthesia protocols to deploy and recover instruments were described in Campagna et al. (1995, 1998, 1999). Tags were configured to send information as soon as the animals entered the water, 24 h per day with repetition rates of 45±6 s in 2003-2004 and 40±6 s in 2005-2006. Locations were received daily via e-mail; Argos provide the estimated accuracy of each location, however, a filter was applied to exclude locations that would require an unrealistic travel rate.
