Ocean current. Distinctive white lines trace the flow of surface currents around the world. An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.

Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise (as seen from the South Pole) from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport estimated at 100–150 Sverdrups (Sv, million m 3 /s ...
High water levels of the Neretva River. [7] Petexbatún River. Pasión River. Central America. Winter rain flooding of the Pasión River. [8] Qiantang River. Hangzhou Bay.
The structure will eventually dissipate due to friction and mixing of water properties. A geostrophic current is an oceanic current in which the pressure gradient force is balanced by the Coriolis effect. The direction of geostrophic flow is parallel to the isobars, with the high pressure to the right of the flow in the Northern Hemisphere, and ...
The North Atlantic Gyre is located in the northern hemisphere in the Atlantic Ocean, between the Intertropical Convergence Zone (ITCZ) in the south and Iceland in the north. The North Equatorial Current brings warm waters west towards the Caribbean and defines the southern edge of the North Atlantic Gyre.
St. Lawrence River. 500 km (310 mi) excluding the estuary. C. 928 km if included. The St. Lawrence River (French: Fleuve Saint-Laurent [flœv sɛ̃lɔʁɑ̃]) is a large international river in the middle latitudes of North America connecting the Great Lakes to the North Atlantic Ocean.
However, within a year the flow at Farakka fell to levels far below the historic average, making it impossible to implement the guaranteed sharing of water. In March 1997, flow of the Ganges in Bangladesh dropped to its lowest ever, 180 m 3 /s (6,400 cu ft/s). Dry season flows returned to normal levels in the years following, but efforts were ...
Map of Nile tributaries in modern Sudan, showing the Yellow Nile The Nile represented in an ancient Roman mosaic found from the ruins of Pompeii. The Yellow Nile is a former tributary that connected the Ouaddaï highlands of eastern Chad to the Nile River Valley c. 8000 to c. 1000 BCE. [49] Its remains are known as the Wadi Howar.
