High quality pH measurements are required in estuarine and coastal waters to assess the impacts of anthropogenic atmospheric CO 2 emissions on marine carbonate system, including resulting decrease pH. In addition, needed determine chemistry phytoplankton blooms their breakdown, following enhanced nutrient inputs. The spectrophotometric technique provides high data seawater, is advantageous for ...

Systems of ocean current power generation are generally moored deep in the seabed. The mooring system is like ropes. ropes very long and can provide tension but not compression, their dynamic displacement large unstable, which different from traditional structures. To generate high-efficiency generation, it necessary to design a stable system. Maintaining stability small invertor significantly ...
