Activities and underwater sounds of fin whales
OLR (1982) 29 (12)
E. Biological Oceanography
Abundance, biomass, 02 consumption and NH 4 excretion of zooplankton decreased with distance (1 to 50 m) above the bottom in 1300 m of water off southern California. Respiration by the mixed macrozooplankton community for the 50-m benthic boundary layer was 3% of sediment community respiration. Scripps Inst. of Oceanogr., La Jolla, Calif. 92093, USA. (mjj)

Deep convective overturn enhances productivity of warm-core eddies; an eddy formed from the East Australian Current in early 1978 overwintered to the south and developed a significant phytoplankton bloom the following spring. A process which tends to terminate such blooms by submerging winter water, relatively rich in nutrients, beneath poorer water of more recent origin is described. CSIRO Mar. Lab., P.O. Box 21, Cronulla, New South Wales 2230, Australia.

zooplankton in relation to habitat zones in the area of the Atlantis II Deep, central Red Sea.
Mar. Ecol.-Prog. Ser., 8(2):129-143. 'Abnormally high temperature (_>21.5°C) and salinity (_>40.5 ppt) in subsurface waters coupled with depleted oxygen in the mesopelagic zone and lack of food in the bathypelagic zone' have led to an unusual plankton distribution. Most net plankton are restricted day and night to the epipelagic zone(0-100 m); in the lower bathypelagic zone (1050-1850 m), biomass is as low as in tropical oceans at depths ~>4000-6000 m.

Almost all hatchling green turtles (Chelonia mydas) were female when eggs were incubated in warm, thermostable nests (>29.5°C) and almost all were male or intersex when incubated in cool and cold nests (,(28°C).

Twenty-three years of acoustic recordings and observations on Balaenoptera physalus are summarized. Routine activities of the whales (deep and shallow diving, slow and rapid swimming, feeding, etc.) were correlated, when possible ('fragmented but consistent'), with some of the more commonly produced sounds, which appear to be communicative and vary in frequency from about 20 to 100 Hz.
