Observations of small scale distributions of chlorophyll : and related physical parameters in British Columbia coastal waters Wiegand, Ronald Clive

Abstract

In the spring of 1973 continuous horizontal measurements were made of temperature, salinity, oxygen and chlorophyll a. in British Columbia coastal waters. The sampling procedure involved a towed pumping system and on-board instrumentation. An effort is made to describe the distributions of the measured parameters with particular emphasis on the smaller scales, less than 250 m. To this end, techniques of power spectral analysis were utilized to examine the data. Results show that there is variability in the nature of the distributions and that the relatedness of the parameters is not consistent, but that on average different experiments show similarities. It appears that to a large extent the distribution of chlorophyll a in an estuarine environment is related to physical transport processes.
