Maintenance and Update Frequency: asNeeded Statement: 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 +/- 0.005?C 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. When all deployments in a year have completed, the Animal Tagging Sub-Facility will conduct delayed-mode QC on the ARGOS positions and hydrographic (CTD) profile data. ARGOS geo-positioning is inherently error-prone, even with the introduction of new geo-positioning algorithms in 2011. The Animal Tagging Sub-Facility uses a state-space model to quality control Argos location data, providing a median accuracy of +/- 3.24 km; see Jonsen et al. (2020) for details. These quality-controlled geo-positions are appended to all datasets (prefix: ...
