The algal sample was kept in place on the gold cathode by means of a black tape ring whose central hole was. Figure 2. The mounting of the algal sample (2) onto the gold cathode (1) of the Beck- man oxygen sensor was achieved through the dialyzing membrane (3) and (6), which was fastened to the oxygen sensor with a black tape ring (4) and (5). covered with a piece of dialyzing diaphragm to allow for access of light and oxygen exchange between the sample and the surrounding water reservoir (Fig. 2). The volume between the diaphragm and the oxygen sensor cathode was filled with filtered sea water. During experiments the oxygen sensor with the sample was inserted in a cup with ml. filtered sea water as outer reservoir. The cup with the sea water was rotated at 72 revolutions per minute. The bottom of the cup was a quartz window to allow for transmission of irradiation in the visible and ultraviolet region of the spectrum (see Halldal, 1964)..
