WebChlorophyll a (Chl a) often exhibits a maximum concentration in the subsurface layer rather that at the surface. The depth of the Chl a maximum primarily depends on the balance between light penetration from the surface and the nutrient supply from the deep ocean. However, a global map of subsurface Chl a concentrations based on observations ... WebMar 23, 2024 · The average flow of the GrijalvaUsumacinta system was ∼ 3600 m 3 s −1 with maximum values up to 10000 m 3 s −1, suggesting that the nitrate contribution of the Grijalva-Usumacinta system has a fundamental role in the chlorophyll response as demonstrated by the EOF and coherence analysis. Nevertheless, as we described …

WebJan 21, 2024 · In deep lakes or reservoirs, maximum chlorophyll concentrations often occur as subsurface chlorophyll maxima (SCM). In this study, a large and deep reservoir in China, Lake Qiandaohu, was selected to investigate the spatial and seasonal variations of the SCM. ... The water layer with a T w gradient ≥0.2 °C/m was defined as the … 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.
