The deep-sea circulation of the Atlantic has recently been carefully analyzed by Wiist (1935) who, on the basis of the tongue-like distribution of temperature and salinity, has drawn conclusions as to the direction of flow at different depths. lie considers that an exchange of deep water be tween the North Atlantic Ocean and the Antarctic Ocean is maintained by a How to the north along the…
Ocean water is a complex solution of many ions. The concentration of this solution varies considerably from place to place but it has been repeatedly shown that the relative concentration of the ions to each other is remarkably constant.
All the viable microorganisms in the air have been transferred to the atmosphere either from the land or the sea. A comparison of the micro-flora of marine air with that of normal sea water and of land areas should indicate the major source of organisms in the atmosphere over the ocean
Corrections have to be applied to the readings of protected and unprotected reversing thermometers because they are read at a temp erature that differs from that at the time of reversal. In deriving these corrections it is generally assumed that Feruglio’s (1912) equa tion [(5) below] is exact. It is shown here that Feruglio’s equation is not quite exact, but a close approximation. Fro…
t has long been recognized that the biological productivity of the sea depends primarily upon the nutrition of the phytoplankton. The aim of these experiments was to study this basic process in the cycle of production by the artificial increase of those plant nutrients most likely to become limiting. For our purpose a body of water was re quired which was large enough to be representative …
