The latest conflict between protesters and Japanese whaling vessels occurred January 15 when a grenade-tipped harpoon was targeted near Greenpeace activists off Mawson Coast
, part of the Australian Antarctic Territory, about 2,000 nautical miles southwest of Perth.
To see where penguins go to fatten up, Wienecke's group fastened satellite trackers and dive recorders onto birds at two colonies along the Mawson Coast
. Instrument packages on nine penguins showed the birds swimming north on a great feeding expedition of 22 to 38 days.
The study was undertaken between May and August 1993 at the Auster (67 [degrees] 23' S, 64 [degrees] 04' E) and Taylor Glacier (67 [degrees] 28' S, 60 [degrees] 54' E) colonies, which lie 150 km apart on the Mawson Coast of Antarctica.
Because the krill body parts were too digested to accurately measure, we assumed that the mass of each individual was 0.6 g, the mean body mass of krill (excluding gravid females) caught during trawling on the Mawson Coast in January 1993 (G.
Satellite images of the Mawson Coast in June revealed that the continental shelf waters 80-240 km east of Auster were virtually free of thick sea ice (Fig.
Probable foraging areas.--The two satellite-tracked Auster females frequented waters in the region of the outer continental shelf and shelf slope [approximately equals] 90-110 km from the Mawson coast (near 67 [degrees] S; Fig.
When leaving the colony after egg-laying, the females headed in a N-NE direction toward the largest area of open water near the colony, a recurring polynya (a regular feature of the Mawson Coast sea ice) that extended south from the slope polynya and was situated over the outer continental shelf (Fig.
Moreover, Adelie Penguins (Pygoscelis adeliae), one-sixth the mass of emperors, often travel [is greater than] 100 km from their colony during foraging trips of [is less than] 3 wk duration from colonies on the Mawson coast (Kerry et al.
