WebJan 19, 2006 · Deep chlorophyll maxima (DCMs) are widespread in large parts of the world's oceans. These deep layers of high chlorophyll concentration reflect a compromise of phytoplankton growth exposed to two opposing resource gradients: light supplied from above and nutrients supplied from below. It is often argued that DCMs are stable features.

WebMay 26, 2015 · The deep chlorophyll maximum layer (ENVO:01000326), often labelled in the literature and databases as “DCM” or “D”, was determined from the chlorophyll fluorometer (WETLabs optical sensors)... WebAug 31, 2024 · The background chlorophyll concentration B0 averaged 0.19 mg chl m −3 ( figure 2 a) and ranged from 0.01 to 1.94 mg chl m … 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. Abiotic factors In-situ studies have determined that the depth of DCM formation is primarily dependent on See more The DCM plays an important ecological role in harbouring much of the world's primary production, and in nutrient cycling. In oligotrophic waters, like the North Sea and the Mediterranean Sea, the DCM is where over half of the overall primary production occurs due to … See more The composition of microorganisms present in the DCM varies significantly with geographical location, season, and depth. The species of phytoplankton present in the DCM varies with depth due to varying accessory pigmentation. Some phytoplankton … See more multipath asm
