Distribution of Euphausiid larvae in the Weddell Gyre in September-October 1989
Distribution of Euphausiid larvae in the Weddell Gyre of late winter was examined. There were only some eggs of Thysanoessa near the ice margin in September, and the eggs and larvae (from nauplius to calyptopis I) were collected under the ice in October. The furcilia VI of Euphausia superba was foun...
