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.
Altogether, the pelagic zone occupies 1,330 million km 3 (320 million mi 3) with a mean depth of 3.68 km (2.29 mi) and maximum depth of 11 km (6.8 mi). [2] [3] [4] Pelagic life decreases as depth increases. The pelagic zone contrasts with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the ...
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.
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.
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]
Wildfires also may be affecting water quality in some of the region’s most pristine lakes, according to a study published in August by researchers at the University of Minnesota-Duluth.
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 ...
