Before revision:  We show that many salient properties, such as the depth of the photosynthesis zone and the net primary productivity (i.e., the effective rate of carbon fixation), are sensitive to T_W, and eventually decline substantially as the ocean temperature is increased.
After revision:  We show that many salient properties, such as the depth of the photosynthesis zone and the net primary productivity (i.e., the effective rate of carbon fixation), are sensitive to PAR flux and T_W and decline substantially when the former is decreased or the latter is increased.
