Distribution of gymnosomatous pteropods in western Antarctic Peninsula shelf waters: influences of Southern Ocean water masses
ABSTRACT Distributions of gymnosomatous pteropods, Spongiobranchaea australis and Clione antarctica , were determined at six sites along a latitudinal gradient in western Antarctica Peninsula shelf waters using vertically stratified trawls. Hydrographic data were collected at the same sites with con...
