Investigations of intensity of krill drift near South Georgia Island
Abstract: Calculation of drift’s speed (transport with current) of Antarctic krill along the ... northeastern shore of South Georgia Island (between 54-55S and 34-39W) were carried out. Length of island’s ... shelf for calculation was assumed about 300 km, but average width of shelf (from shore to 500 m isobate ... ) was assumed about 60 km. Speed of drift in these spatial limits was assumed about 10 cm sec-1. The ...
