Abstract
In temperate latitudes the oxygen content of sea water near the surface varies with seasons. This occurs since the solubillity of oxygen in sea water changes with water temperature and further since the production and utilization of oxygen by organisms are not equal in different seasons.
A. C. Redfield estimated the exchange of oxygen across the sea surface (ΔQE) and the net production of oxygen by organisms (ΔQX) during the period of observations. He concluded that ΔQX is equal to two fifths of ΔQE using the data of oxygen content in the waters of the Gulf of Maine.
In the present paper the anther has made an attempt to determine the magnitude of ΔQE and ΔQX- in Gotonada, pointing out the error of Redfield's estimation.
