An ocean current that flows southward from Baffin Bay, through the Davis Strait, thence southeastward past Labrador and Newfoundland. East of the Grand Banks, the Labrador current meets the Gulf Stream , and the two flow east separated by the cold wall .

An ocean current that is one of the terminal branches of the Gulf Stream system (part of the northern branch of the North Atlantic current ); it flows toward the west off the south coast of Iceland. A small portion of the water of the Irminger Current bends around the west coast of Iceland but the greater amount turns south and becomes more or less mixed with the water of the east Greenland current .

An ocean current, the northern branch of the north equatorial current flowing along the northern side of the Great Antilles carrying water that is identical with that of the Sargasso Sea. The Antilles current eventually joins the Florida current (after the latter emerges from the Straits of Florida) to form the Gulf.

An ocean current, the northward flowing division of the Aleutian current . It circulates cyclonically around the Gulf of Alaska; part of the water passes between the Aleutian Islands into the Bering Sea from which it emerges as the Oyashio , and part rejoins the Aleutian current. It enters the Gulf of Alaska along the American west coast and, since it comes from the south, it has the character of a warm current in spite of the fact that it carries subarctic water. It therefore exercises an influence on climatic conditions similar, on a small scale, to that which the North Atlantic current and Norwegian current exercise on the climates of northwestern Europe. Aleutian current - also called subarctic current. An eastward flowing ocean current which lies north of the North Pacific current; it is the northern branch of the Kuroshio extension which moves northeast then east between 40=AE$=AFN and 50=AE$=AFN. As it approaches the cost of North America it divides to form the northward-flowing Alaska current and the southward-flowing California current.
Industry:Earth science
An ocean wave produced by a submarine earthquake, landslide, or volcanic eruption. These waves may reach enormous dimensions and have sufficient energy to travel across entire oceans. They proceed as ordinary gravity waves with a period between 15 and 60 minutes. Tsunamis steepen and increase in height on approaching shallow water, inundating low-lying areas; and where local submarine topography causes extreme steepening, they may break and cause great damage. Tsunamis have no connection with tides ; the popular name is entirely misleading.
Industry:Earth science
An ocean wave traveling parallel to a coast, with crests normal to the coast line. Such a wave has a height that diminishes rapidly seaward and is negligible at a distance of one wave length offshore.
Industry:Earth science
An oceanic region whose cotidal lines radiate from one amphidromic point.
Industry:Earth science
An orbit timed for a satellite to proceed over any given point on the landscape at roughly the same local sun time, providing repeatable sun illumination conditions during specific seasons.
Industry:Earth science
An oscillation of a fluid body in response to a disturbing force having the same frequency as the natural frequency of the fluid system. Tides are now considered to be seiches induced primarily by the periodic forces caused by the sun and moon.
Industry:Earth science
Annual or semi-annual changes in sea level due to shifts in prevailing winds or seasonal changes in water temperature; distinguish from atmospheric tide.
