WebJan 19, 2006 · In many parts of the oceans a layer known as a ‘deep chlorophyll maximum’ develops about 50 to 100 metres below the surface as various opposing forces achieve a balance. Phytoplankton sinking ... WebVoituriez (1979). In the TTS, the upper layers of the eu- photic zone are nutrient-depleted, the lower levels are light-limited, and a deep chlorophyll maximum (DCM) occurs within the layer of density stratification, in close association with the nutricline. Based on the relation- ships between hydrographical and biological features

The deep chlorophyll maximum (DCM), also called the subsurface chlorophyll maximum, is the region below the surface of water with the maximum concentration of chlorophyll. The DCM generally exists at the same depth as the nutricline, the region of the ocean where the greatest change in … See more The DCM is often located tens of meters below the surface, and cannot be observed by using traditional satellite remote sensing methods. Estimates of primary productivity are often made via these remote … See more Since its initial discovery, oceanographers have presented various theories to explain the formation of deep chlorophyll maxima.
