The Hawaiian Trough, otherwise known as the Hawaiian Deep, is a moat -like depression of the seafloor surrounding the Hawaiian Islands. The weight from the volcanic island chain depresses the plastic lithosphere that is already weakened by the underlying thermal hotspot, causing subsidence to occur. The location with the greatest rate of ...

The Kalohi Channel is the stretch of water separating Lānaʻi and Molokaʻi.Depth of water in this channel is about 260 feet (79 m) and width is 9.3 miles (15.0 km). This is one of the less treacherous channels between islands in the archipelago, although strong winds and choppy sea conditions are fre
International waters are the areas shown in dark blue in this map, i.e. outside exclusive economic zones which are in light blue. The terms international waters or transboundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems ...
The Hawaiian Islands ( Hawaiian: Mokupuni Hawai‘i) are an archipelago of eight major volcanic islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some 1,500 miles (2,400 kilometers) from the island of Hawaiʻi in the south to northernmost Kure Atoll. Formerly called the Sandwich Islands[ a] by Europeans ...
Territorial sea is a belt of coastal waters extending at most 12 nautical miles (22 km; 14 mi) from the baseline (usually the mean low-water mark) of a coastal state. [ 6] The territorial sea is sovereign territory, although foreign ships (military and civilian) are allowed innocent passage through it, or transit passage for straits; this ...
As the sea level was considerably lower 7,000 to 8,000 years ago than it is today, the pond originally sat above the water table, and was filled only by rainfall and runoff from the surrounding land. At that time the pond had a relatively thin layer of peat under a thin layer of water. The subsequent rise in sea level raised the local water ...
