Descripción
The resource contains 3181 data derived from sensors (Time Depth Recorder) placed on southern elephant seals. Sea temperature, depth and diving location were stored in eMof format as mean, minimum and maximum values. Data were obtained during the marine-pelagic phase of 9 seals tracked between 1995 to 2008, along the SW Atlantic Ocean, covered all seasons. The novelty of this dataset is that being also available as Linked Open Data (LOD) through the SPARQL endpoint http://linkeddata.cenpat-conicet.gob.ar/snorql/. The dataset is a subset of a larger dataset (Records at sea of juveniles southern elephant seals,Mirounga leonina, from Península Valdés, Argentina) http://arobis.cenpat-conicet.gob.ar:8081/resource?r=mleonina_juv

Datos del proyecto
The program started in 1990 to study ecology and life history strategies of southern elephant seals, together with the research of foraging areas in the ecosystem of SW Atlantic Ocean. The research site on land is mainly Península Valdés (PV), which has been a UNESCO World Natural Heritage since 1999. Ancillary bio-logging work addresses diving behavior in an ecosystem context providing a greater understanding of fundamental ecosystem processes in the South Atlantic Ocean, using southern elephant seals as oceanographic sampling platform.

| Descripción del área de estudio | The geographic coverage of the project includes the Patagonian coast of Argentina, with Península Valdés as the main point of field work and observation. The Patagonian shelf, from the edge of the Patagonian shelf and 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. |
| Descripción del diseño | Systematics studies were conducted on southern elephant seals. Standardized surveys provided information on the abundance, trend, change in distribution and movements at sea could be used as conservation indicators and spatial planning. Deployment and recoveries of data loggers from animals that breed and molt at Peninsula Valdes provided information regarding locations, behavior and habitat use. |

Métodos de muestreo
Satellite tags (SPOT4/SPOT5 and SPLASH Wildlife Computers, Redmond, Washington, http://www.wildlifecomputers.com) and TDR were deployed on 8 juveniles southern elephant seals and one subadult male, during their haul out at Península Valdés, Patagonia, Argentina. Tags were configured to send information through Argos System as soon as the animals entered the water. The configuration of satellite telemeters and the location data analyses were described in Campagna et al. (2006, 2007).
| Área de Estudio | Records coverage locations during the foraging pelagic trip that includes the marine plateaus in the Southern Hemisphere, 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 Peninsula Valdes. Temporal coverage is described as interval tracking. Each track session starts when the animal is tagged and finished when the instrument is recovered. 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. |
|---|---|
| Control de Calidad | The oceanographic vocabulary use the Natural Environment Research Council (NERC) Vocabulary Server and GeoSPARQL for supporting the representation and querying of geospatial data on the Semantic Web. All sampling locations have been plotted on a map to perform a visual check if all sampling locations are within the described sampling area. |
Descripción de la metodología paso a paso:
- 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). 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 (Campagna et al 2006,2007) . 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. Location of hydrographic data belongs to upward phase of the dive.
