Chemical Changes In Sea Water off Plymouth in 1961

Abstract

The results of analysis of sea water samples from the International Hydrographic Station E1 (500 02' N., 40 22' W.) are given in graphical form and as integral mean values for the water column of 70 m. Winter maximum values (in January) of 044/xg atom phosphate P/l. and 0-53^g atom ' T o t a l ' P/L, with 315/xg atom Si/1, were found. The phosphate and total phosphorus concentrations were unusually low. The spring decreases were 0-21/xg atom P/l. and 272 fig atom Si/1.
