Sea Water, The Natural Medium of Phytoplankton I. General Features
Preliminary culture assays were made using marine algae to elucidate the ‘quality’ of sea waters from the North Sea and North Atlantic Ocean for phytoplankton growth. Assays with (a) bacteria-free Skeletonema costatum , (b) unialgal Skeletonema and Peridinium trochoideum and (c) mixed phytoplankton...
