"WebIn fact, the photic zone accounts for 95% of all photosynthesis in the ocean. As a result, there is little to no phytoplankton beyond the photic zone, such as in the compensation point, due to insufficient sunlight. The dysphotic zone, which stretches from the base of the euphotic zone to roughly 200 metres, is occasionally referred to as such. " - Photic vs euphotic zone

WebFeb 19, 2024 · The euphotic zone is the layer closer to the surface that receives enough light for photosynthesis to occur. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiration exceed those of photosynthesis. The actual depth of these zones depends on local conditions of cloud cover, water turbidity, and ocean surface.

WebThe results based on equation (2) show that the correlation between NPP and HWF/WWF is greatly improved both seasonally and monthly compared to the results of equation (1) (Table 1).
