An old term for the interval of time at a particular location, between the transit (upper or lower) of the moon and the next semidiurnal high water. This varies slightly during a spring-neap tidal cycle. The interval at the times of full and new moon is called “high water full and change. ” See nonharmonic tidal analysis, cotidal hour.

The resultant current produced by waves being deflected at an angle by the shore. In this case the current runs roughly parallel to the shoreline. The longshore current is capable of carrying a certain amount of material as long as its velocity remains fairly constant; however, any obstruction, such as a submarine rock ridge or a land point cutting across the path of the current, will cause loss of velocity and consequent loss of carrying power.

A water mass found in the Japan Sea below a depth of 200 m (84% of the volume of the Japan Sea). Being isolated from all other oceans, it has very uniform salinity (34. 1) and temperature (0°– 1°C). See deep water.

One of the western boundary currents of the North Pacific subtropical gyre. A deep, narrow, and swift current, it continues from the Philippines Current in a northeastward direction from Taiwan along the continental rise of the East China Sea, through Tokara Strait, and close to the eastern coast of Japan. At 35°N it separates from the coast and flows eastward into the Pacific as a free jet known as the Kuroshio Extension. It forms a marked temperature and salinity front with the Oyashio, which meets the Kuroshio Extension from the north and then flows parallel to it. Like all other western boundary currents, the Kuroshio develops instabilities and sheds eddies. Its unique characteristic is that south of Honshu it switches between three quasi- stable paths across the Izu Ridge at irregular intervals of 18 months to several years. Volume transport in the Kuroshio increases downstream and reaches 57 Sv (57 × 106 m3s−1) in the Kuroshio Extension, increasing seasonally by 15% during summer. The current's path in the extension is characterized by large meridional excursions in the so-called First and Second Crest at 145° and 152°E. On approaching the Shatsky Rise at 157°E, the Kuroshio Extension divides into several paths that tend to recombine before the Emperor Seamounts near 170°E cause the current to split again and disintegrate. The flow then continues as the North Pacific Current.
