Description

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

Sampling Description

Study Extent

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.

Sampling

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).

Quality Control

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.

Method steps

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.
