Benthic-pelagic coupling are processes that connect the benthic zone and the pelagic zone through the exchange of energy, mass, or nutrients. These processes play a prominent role in both freshwater and marine ecosystems and are influenced by a number of chemical, biological, and physical forces that are crucial to functions from nutrient cycling to energy transfer in food webs.
This amount will vary on the depth of the benthos, and the degree of benthic-pelagic coupling. The benthos in a shallow region will have more available food than the benthos in the deep sea. Because of their reliance on it, microbes may become spatially dependent on detritus in the benthic zone.
The Southern California Coastal Water Research Project (SCCWRP) is a research institute focusing on the coastal ecosystems of Southern California from watersheds to the ocean. SCCWRP was created as a joint powers authority (JPA), which is an agency formed when multiple government agencies have a common mission that can be better achieved by ...
Under the Federal Clean Water Act and the state's pioneering Porter-Cologne Water Quality Control Act the State Water Board has regulatory authority for protecting the water quality of nearly 1,600,000 acres (6,500 km 2) of lakes, 1,300,000 acres (5,300 km 2) of bays and estuaries, 211,000 miles (340,000 km) of rivers and streams, and about ...
The fish in the different pelagic and deep water benthic zones are physically structured, and behave in ways, that differ markedly from each other. Groups of coexisting species within each zone all seem to operate in similar ways, such as the small mesopelagic vertically migrating plankton-feeders, the bathypelagic anglerfishes , and the deep ...
Pelagic food web and the biological pump. Links among the ocean's biological pump and pelagic food web and the ability to sample these components remotely from ships, satellites, and autonomous vehicles. Light blue waters are the euphotic zone, while the darker blue waters represent the twilight zone. [61]
The concentration of interstitial water reflects the chemical's activity and is a surrogate for bioavailability. [6] EqP theory holds that a non-ionic chemical in sediment partitions between sediment OC, interstitial water and benthic organisms. For cationic metals, the chemical also partitions onto sediment AVS, as well as sedimentary OC.
The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides. Other near-shore (neritic) zones can include mudflats , seagrass meadows , mangroves , rocky intertidal systems , salt marshes , coral reefs , lagoons .
