El plancton del Atlantico suroeste: dinamica y ecologia
Plankton was collected in Nov.-Dec. 1972, during the Cato-6 Expedition (R/VMelville). Distribution of Siphonophores and Medusae and ecological implications pointed out by these organisms are discussea. 25 species of Siphonophorae were obtained corresponding to tropical, temperate, and Antarctic Sub...
