It involves strong tidal currents flowing through the shallows between these islands and the Atlantic Ocean and the deep Vestfjorden, creating eddies and whirlpools, the largest one having a diameter of some 40–50 meters (130–160 ft) and inducing surface water ripples up to 1 meter (3 ft 3 in) in amplitude.
Many guts are straits but some are at a river mouths where tidal currents are strong. The comparatively large quantities of water that flow quite quickly through a gut can cause heavy erosion that results in a channel deeper than the rest of the surrounding seabed, and the currents may present a hazard to ships and boats at times.
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.
A rip tide, or riptide, is a strong offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide. It is a strong tidal flow of water within estuaries and other enclosed tidal areas. The riptides become the strongest where ...
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 combination of more sewage, due to the availability of more potable water – New York's water consumption per capita was twice that of Europe – indoor plumbing, the destruction of filter feeders, and the collapse of the food chain, damaged the ecosystem of the waters around New York, including the East River, almost beyond repair.

The circumpolar current merges the waters of the Atlantic, Indian, and Pacific Oceans and carries up to 150 times the volume of water flowing in all of the world's rivers. The study found that any damage on the cold-water corals nourished by the current will have a long-lasting effect. [6]
The greatest southbound current occurs about one and a quarter hours before Bodø high tide, when the inflowing current reaches about 7 knots (13 kilometres per hour). The speed of the current has a broad maximum being greater than 6 kn (11 km/h) from three hours before Bodø high tide until half an hour after Bodø high tide.
