Weddell seal tracking and diving data from expedition FIL2021

Weddell seals (Leptonychotes weddellii) were instrumented during expedition PS124 (2021) for the purpose of deployments with satellite transmitters. The deployments (n=10) were located in the Filchner-Outflow-System (FOS), southern Weddell Sea. The seals (7 female, 3 male) were captured along the sh...

Description
Summary:Weddell seals (Leptonychotes weddellii) were instrumented during expedition PS124 (2021) for the purpose of deployments with satellite transmitters. The deployments (n=10) were located in the Filchner-Outflow-System (FOS), southern Weddell Sea. The seals (7 female, 3 male) were captured along the ships' tracks during ahead flights of the board helicopter and immobilised and instrumented on pack ice with Argos-linked (CLS, Toulouse, France) satellite-relayed dive loggers combined with CTD's (CTD-SRDLs, Sea Mammal Research Unit, UK) to investigate their ranging and foraging behaviour in the context of oceanographic features. Six of the ten CTD-SRDLs provided data. The average lifetime of PTTs was 124.7 days ( MIN 2; MAX 233). The entire workflow and data processing routines are outlined in a data processing report.
