7. Winter foraging ranges of Weddell seals: a pilot study to assess their role in the winter sea-ice zone and their potential as ocean sampling platforms [ASAC_2695]
Metadata record for data from ASAC Project 2695 See the link below for public details on this project. Variations in the winter extent of sea ice are thought to have profound effects on biological ...


8. Geographic variations in underwater male Weddell seal Trills suggest breeding area fidelity [ASAC_1132-2]
Adult Weddell seals (Leptonychotes weddellii) exhibit site fidelity to where they first breed but juveniles, and perhaps transient adult males, may disperse from their natal location. If there is ...


9. Measuring the effects of human activity on Weddell Seals (Leptonychotes weddellii) [ASAC_1148_Weddells]
The number of people travelling to Antarctica is growing, with much of the recent increase in visitor numbers attributable to an expansion in commercial tourism (Enzenbacher 1992; 1994). Most visitors ...
