Adult male and female Weddell seals (Leptonychotes weddellii) were fitted with Time-depth (TDR) and Stomach temperature recorders (STR) at Drescher Inlet (Riiser Larsen Ice Shelf), eastern Weddell Sea coast, between January and March 1995. Ten of 15 data sets were selected for analyses to investigate the seals' haul-out and underwater activity patterns in relation to the tide (doi:10.1594/PANGAEA.511417, doi:10.1594/PANGAEA.511426, doi:10.1594/PANGAEA.511428, doi:10.1594/PANGAEA.511430, doi:10.1594/PANGAEA.511432, doi:10.1594/PANGAEA.511441, doi:10.1594/PANGAEA.511444, doi:10.1594/PANGAEA.511450, doi:10.1594/PANGAEA.511452, doi:10.1594/PANGAEA.511472). These data sets provided simultaneous dive depth and stomach temperature records of five seals. Diving and temperature data were analysed with the help of time series analyses tools. We identified a half-day (semicircadian) rhythm in underwater activity and body temperature. A close correlation was found between the rhythmicity of the tide and the timing of ... : Supplement to: Bornemann, Horst; Mohr, Elmar; Plötz, Joachim; Krause, Gunther (1998): The tide as zeitgeber for Weddell seals.
