For example, the ocean current that brings warm water up the north Atlantic to northwest Europe also cumulatively and slowly blocks ice from forming along the seashores, which would also block ships from entering and exiting inland waterways and seaports, hence ocean currents play a decisive role in influencing the climates of regions through ...
A current in a fluid is the magnitude and direction of flow within each portion of that fluid, such as a liquid or a gas. Types of fluid currents include: Air current; Water current Current (hydrology), a current in a river or stream; Ocean current. Longshore current; Boundary current; Rip current; Rip tide; Subsurface currents. Turbidity ...
The water in this stream forms varying currents as it makes its way downhill. In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry.
Aerial view of a BC Ferry at Active Pass sailing from Trincomali Channel in the west. Active Pass (Saanich: SḴŦAḴ) [1] is a strait separating Galiano Island in the north and Mayne Island in the south in the southern Gulf Islands, British Columbia, Canada. It connects the Trincomali Channel in the west and the Strait of Georgia in the east ...
In general, strong currents called western boundary currents form at the eastern boundary of continents. These strong currents can transport water masses over a large distance, bringing them in contact with water masses that have very different properties. These differences in properties together with factors such as speed cause very strong ...
The mooring is held up in the water column with various forms of buoyancy such as glass balls and syntactic foam floats. The attached instrumentation is wide-ranging but often includes CTDs (conductivity, temperature depth sensors), current meters (e.g. acoustic Doppler current profilers or deprecated rotor current meters), and biological sensors to measure various parameters.

An example of a geostrophic flow in the Northern Hemisphere. A northern-hemisphere gyre in geostrophic balance. Paler water is less dense than dark water, but more dense than air; the outwards pressure gradient is balanced by the 90 degrees-right-of-flow coriolis force. The structure will eventually dissipate due to friction and mixing of water ...
