Biophysical Characteristics

The occurrence of zooplankton off Tema during the period 1969 – 1992


Displacement volumes of zooplankton  samples collected with the ICITA net at  four  stations along an  oceanographic  transect  off  Tema  at  approximately  weekly intervals  over the period, 1969 – 1992, are analysed.
