BOTTOM TYPE 'PLANKTON ICE' IN THE ARCTIC OCEAN
A summer field survey off Point Barrow, Alaska, revealed a growth of photosynthetic diatoms in Arctic sea ice. The diatoms are found in a brine solution in microfissures between ice crystals on the underside of the ice. The chlorophyl content of this layer is 100 times that of the surrounding sea wa...
