Description
Summary:Maintenance and Update Frequency: asNeeded Statement: Tag deployments on southern elephant seals and Weddell seals occur annually. Deployments on southern elephant seals typically range from December through January. Deployments on Weddell seals typically range from February through March. Individual deployments can last until October/November for southern elephant seals and until September/October for Weddell seals. Shorter deployment durations occur when tags fall off or otherwise fail prematurely. Animal Tracking Facility SRDL logger data have been supplied to IMOS by Animal-Tagging Sub-Facility participants, via the Sea Mammal Research Unit (SMRU, St Andrews University, UK). Tags used on southern elephant seals and Weddell seals - CTD Oceanography Satellite Relay Data Loggers (Argos) - collect conductivity, temperature and depth information. On some seals - CTD/Fluorometer Oceanography SRDL (Argos) - collect conductivity, temperature, fluorescence and depth information. The CTD Oceanography SRDL (Argos) and CTD/Fluorometer Oceanography SRDL (Argos) are built by SMRU and incorporate CTD sensors developed by Valeport Ltd (Devon, UK) and a Turner Cyclops-7 fluorometer sensor developed by Turner Designs (San Jose, US). The CTD 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 +/- 0.005oC and +/- 0.01 mS/cm, respectively. Before being taken into the field, devices are calibrated in the laboratory by Valeport. CTD-SRDLs and CTD/Fluorometer 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 Animal-Tagging Sub-Facility conducts an automated, near real-time QC on the ARGOS positions ...
