Maintenance and Update Frequency: asNeeded Statement: The Animal Tracking Facility Satellite Relay Tag data has been supplied to IMOS by participants, via the St Andrews University Sea Mammal Research Unit. Tags used on species: Australian Fur Seal, Australian Sea Lion, New Zealand Fur Seal and Southern Elephant Seal - CTD Satellite Relay Data Loggers (SRDL). Collect conductivity, temperature and depth information. On some Australian Sea Lions - CTD/Fluorometer Satellite Relay Data Loggers (SRDL). Collects conductivity, temperature, fluorescence and depth information. Weddell Seals - Satellite Relay Data Loggers (SRDL). Collect temperature, speed and depth information. CTD-SRDLs The CTD–Satellite Relay Data Loggers (CTD-SRDLs) are built by the Sea Mammal Research Unit (SMRU, University of St. Andrews, UK), incorporating CTD sensors developed by Valeport Ltd (Devon, UK). The sensor head consists of a pressure transducer, a platinum resistance thermometer, and an inductive cell for measuring conductivity. The temperature and conductivity sensors have a precision (repeatability) of 0.005°C and 0.005 mS/cm, respectively. Before being taken into the field, devices are calibrated in the laboratory by Valeport. Some of the CTD-SRDLs (about half) were also tested at sea against a ship-based CTD before the deployment. CTD-SRDLs record hydrographic profiles during the ascent of seals, retaining only the deepest dive in each six-hour time interval, and transmitting profiles in a compressed form (between 10 and 25 data points per profile, depending on the tag program) through the Advanced Research and Global Observation Satellite (ARGOS) system. The accuracy of ARGOS geo-positioning is typically better than ±5 km, because seals never stay at the surface more than a few minutes. New methods are currently under development by the ARGOS team, which should substantially improve the quality of positioning. Hydrographic profiles are post-processed using a unified procedure of editing, adjustment, and validation. A standard set ...
