Distribution of euphausiid larvae along the coast of East Antarctica in the Dumont d'Urville Sea (139–145°E) during summer 2004
Abstract The distribution of euphausiid larvae along the coast of Terre Adélie, Antarctica, was assessed using oblique tows of a double-framed bongo net at 38 stations during summer 2004. Larvae of Euphausia crystallorophias and Thysanoessa macrura were observed. For E. crystallorophias larvae, the...
