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.
The Porter-Cologne Act (California Water Code, Section 7) was created in 1969 and is the law that governs water quality regulation in California. The legislation bears the names of legislators Carley V. Porter and Gordon Cologne. [1] It was established to be a program to protect water quality as well as beneficial uses of water.
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 ...
The open sea The pelagic water column is the major part of the living space at sea. This is the water between the surface and the top of the benthic zone , where living organisms swim, float or drift, and the food chain starts with phytoplankton , the mostly microscopic photosynthetic organisms that convert the energy of sunlight into organic ...
California's pioneering clean water act is the 1969 Porter-Cologne Water Quality Control Act (Porter-Cologne Act). [5] Through the Porter-Cologne Act, the State Water Board and the Regional Water Boards have been entrusted with broad duties and powers to preserve and enhance all beneficial uses of the state's immensely complex waterscape.
Sea water, in theory, could be used to help a fire. But, its salty components can do more harm than good, which is why firefighters typically avoid using it unless absolutely necessary.
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.
Most deep sea pelagic fishes belong to their own orders, suggesting a long evolution in deep sea environments. In contrast, deep water benthic species, are in orders that include many related shallow water fishes. [71] The umbrella mouth gulper is a deep sea eel with an enormous loosely hinged mouth. It can open its mouth wide enough to swallow ...
