Plankton Production and the Nitrate Nitrogen and Phosphate Cycles in the Pacific Ocean off New South Wales

Abstract

RECENT quantitative research into the production of plankton and more especially into the seasonal cycle of plankton production has been accompanied by a keen appreciation of more accurate chemical analyses of sea-water. Whilst the complexity of the interrelationships between the biological and the physico-chemical conditions in the sea are being thoroughly realised, some rather definite and interesting correlations have been already demonstrated, and the investigation of the different seas in different latitudes promises further light on this subject.
