El plancton de Mar del Plata durante el período 1961-1962 (Buenos Aires, Argentina)
The first part presents a general picture of the composition of the coastal plankton near Mar del Plata (Buenos Aires prov., Argentina) between August 1961-August 1962. Especially noted is the abundance of Noctiluca from October to the end of March. The second part deals with the plankton collected...
