Pelagic vs benthic
WebAll of the ocean’s open water is referred to as the pelagic zone. The benthic zone extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor. Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m ...

WebApr 10, 2024 · Overall, the results found that WLF and nutrient dynamics in the pelagic zone of Lake Kinneret are not co-partners, but independent escorts. The common periodical (monthly) distribution of nutrient concentrations in the epilimnion of Lake Kinneret indicates that a 20 m deep epilimnion formed following a decline in water input, temperature, and ... WebBorum and Sand-Jensen (1996) found significant variation in the contributions of benthic versus pelagic production to total primary production rates for temperate coastal ecosystems. However, they also found that a majority (70%) of production rates were remarkably consistent, between 250 and 500 g-C m −2 yr −1 ( Figure 2 ).

WebNov 6, 2024 · Unlike its sister zones, the benthic (from Greek: “Depth of the sea”) zone is characterized not by its depth but by the body of water itself. The benthic zone is the lowest level of the ocean, encompassing the sediment surface and the water level right above it, starting from the shoreline and expanding to the deepest part of the ocean floor.
