Oxygen (O2) is critical for sustaining marine life and regulates important elemental cycles in the ocean, such as those of nitrogen, phosphorus, and iron1. Observations indicate that the global ocean dissolved O2inventory, currently estimated at 227.4 ± 1.1 Pmol2, has decreased by >1%...
The frequency-varying electrical energy from the stator windings of the generator is converted into direct current by a full-power converter, and then inverted into the constant frequency of power grid. The DDWT could be electrically or permanent-magnet excited. Due to the absence of the speed-...

Wind energy, as a renewable energy source, offers the advantage of clean and pollution-free power generation. Its abundant resources have positioned wind power as the fastest-growing and most widely adopted method of electricity generation. Wind speed st
Offshore wind energy is defined as the energy generated from the wind at sea, and ocean energy as the energy present in oceans and other water bodies in the form of: waves, marine currents, tides, ocean thermal energy gradients or salinity gradients. ...
Wind stress may either enhance or oppose the density-driven coastal current. Kourafalou et al. [1] showed that downwelling favorable winds strengthen the coastal current plume region and confine the bulge nearshore, while upwelling favorable winds may reverse the coastal current and allow a wide ...
These spectra are used to obtain the growth of the spectral components at various frequency bands for increasing wind and different values of fetch and current. The results indicate that the growth of these components is not monotonic with the frictional wind speed, but rather exhibits an '...

Current energy storage systems can be divided into five main categories: mechanical energy storage, electrochemical energy storage, electromagnetic energy storage, thermal energy storage, and chemical energy storage. Electrochemical energy storage utilizes the conversion between electric energy and chemical ...
