Abstract:

Weddell seals (Leptonychotes weddellii) were immobilised during expedition NEU2022 (ANT-Land 2022/2023) for the purpose of deployments with infrared (IR) camera loggers (CAM). The IR-CAM deployments (n=17) were located in the Atka-Bay in the vicinity to the Neumayer Station III (DE), eastern Weddell Sea. The seals were searcher by Skidoo and captured along tidal within the bay and immobilised and instrumented on fast (bay) ice with infrared video camera loggers (IR-CAMs, Little Leonardo, JP) to investigate their foraging behaviour in the context of sea ice features inside the bay.
