112-472: The potential to generate significant tidal power using tidal stream turbines . Tides are more predictable than wave power or wind power . The Pentland Firth (a strait) may be capable of generating 10  GW . Cook Strait in New Zealand may be capable of generating 5.6 GW even though the total energy available in the flow is 15 GW. Straits used for international navigation through

126-442: The strait in both directions. In some straits there may be a dominant directional current through the strait. Most commonly, it is a narrowing channel that lies between two land masses . Some straits are not navigable, for example because they are either too narrow or too shallow, or because of an unnavigable reef or archipelago . Straits are also known to be loci for sediment accumulation. Usually, sand-size deposits occur on both

140-818: The strait is between Phipp Point and Maie Point, both in Alaska. The strait was named by Captain Daniel Pender in 1868 as part of surveying of the coast, in association with Pearse Island .

There may be no suspension of innocent passage through such straits. [REDACTED] Media related to Straits at Wikimedia Commons Pearse Canal Pearse Canal
