technology harness energy mixing freshwater seawater
2019/10/22
Salt is power. The energy in places where salty ocean water and freshwater mingle could provide a massive source of renewable power. Stanford University researchers have developed an affordable, durab...
Colonial New Delhi had a cobra infestation. To get rid of it, the government offered bounties for dead cobras, inadvertently turning cobra breeding into a thriving business. When the government got wi...
Microbes and the Dissipation of Energy and Respiration: From Cells to Ecosystems
Energy and Respiration From Cells
2015/7/22
In the year 1974, Larry Pomeroy first proposed that microbes were true movers of energy and nutrients in marine food webs (Pomeroy, 1974). This idea was later formalized as the "microbial loop" (Azam ...
Analysis of Energy Flow in US GLOBEC Ecosystems Using End-to-End Models
Sea continental shelf the ecosystem nutrition structure global ocean ecosystem dynamics
2015/7/16
End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the North...
The sun inputs huge amounts of heat to the ocean, heat that would stay near the ocean's surface if it were not mechanically mixed into the deep. Warm water is less dense than cold water, so that heate...
Energy Transfer Through Food Webs at Hydrothermal Vents:Linking the Lithosphere to the Biosphere
Energy Transfer Food Webs Hydrothermal Vents Lithosphere Biosphere
2015/7/14
Tectonic and volcanic processes that drive hydrothermal fluid flow and influence its chemistry also regulate the transfer of energy to hydrothermal vent ecosystems. Chemoautotrophic bacteria use the c...
The total radiant energy, and the average depth of all the photons, in the water column
The total radiant energy the average depth all the photons in the water column
2014/4/2
Using radiative transfer theory I show that for a given waveband, the total radiant energy,Qt, present within the water column (per square meter of surface) is proportional to the scalar irradiance ju...
