摘要: The under-ice behavior of two free-ranging female Weddell seals (Leptonychotes weddellii) was studied using geomagnetic, acceleration and velocity sensors at Big Razorback Island in McMurdo Sound, Antarctica. seals' body angle posture were calculated from the data heading geomagnetic intensity data. Together with swim speed, three-dimensional underwater dive path, even reconstructed for each dive. Each instrument deployed 2 days, during which time these females made multiple, deep (≥50 m) dives, average maximum depths 236±27 m (n=4) 244±121 m (n=40). seal appeared to choose a particular on descend. These headings significantly different between bouts (Watson's U 2 test, P<0.05). new instruments methodologies are shown provide valuable information fine-scale complex movements diving animals.
