To understand why the magnetic field variations preceded the sea-level changes at Chichijima Island, we compared the computed magnetic field variation to the patterns of seawater flow and induced electric currents around Chichijima Island (Fig. 7).
As the next step, we obtained the electric current in the seawater flow arising from the induced magnetic field b.
Our analysis involved three steps: first, computation of the flow of seawater in the simulation; second, computation of the electric current induced by seawater flow; and third, computation of the resulting magnetic field variations on the basis of the Biot-Savart law.
We computed the induced electric currents using the previously computed seawater flow.
For the ocean cage-fishing farms, seawater temperatures, weathers, currents and tides should be considered while for the land-based farms, water temperatures, pH and salinity are the important factors.
Proposals to extract uranium from seawater are currently "useless" because "the energy needed to extract and process uranium from seawater would be about the same as the energy that could be obtained by the same uranium using the current nuclear technology".
One major output of this research is the assessment of the generation of heat in the seawater by alternating current during evaporation process for near-ZLD; although, more studies are needed for continuous pilot production system, modelling for commercial production as well as economical evaluation of the system.
In the current study, DOC in artificial seawater noticeably changed the voltammetric currents throughout the Hg/Au polarization range (Figure 18).
Inductive Contactless Power Transmission (ICPT) may suffer considerable power loss due to eddy currents in seawater when applied undersea rather than on land.
The source is beneath 1600 meters of seawater, the winds and currents spreading the oil can be capricious, and the marine life in the oil's path is spread over hundreds of square kilometers, from the sea floor to the surface.
