Abstract

Although there is a mass of data available on the physical and chemical properties of sea water in various part., of the world, relatively little data may be had from localities where continuous long time observations have been made. At the Oceanographic Laboratories on San Juan Channel near Friday Harbor, Wash., the water body is unique in that it is rather homogeneous for a depth of 100 meters. We propose to demonstrate the yearly and seasonal variations and fluctuations of the physical and chemical properties, and the phytoplankton calendar of this water mass and to determine if long time periodicities exist. Data on the seasonal variation of the physical and ....
