2022年10月19日 · In the drying lake bed, sunken ships volcanic ash and lost cities have been discovered thus far. Here’s a closer look at what is found when waters recede. Where Is Lake Mead? Lake Mead forms from the Hoover Dam on the Colorado River. It’s a reservoir that provides water for parts of California, Nevada and Arizona.

2019年7月16日 · In 2007, while searching for the remains of sunken ships, scientists discovered a stone structure at a depth of 12 meters in Lake Michigan (USA). The discovery was made by Marc Holly, professor of underwater archeology at the Northwestern University of Michigan, and his colleague Brian Abbott.

Steel and iron, depending on their thickness, may retain the ship's structure for decades. As corrosion takes place, sometimes helped by tides and weather, the structure collapses. Thick ferrous objects such as cannons , steam boilers or the pressure vessel of a submarine often survive well underwater in spite of corrosion.

Over time, as a complex community of fishes gather and colonize the reef, a carpet of algae, corals and other invertebrates grow on the structure’s surface. The currents curling around a sunken structure likely push up clouds of plankton, the essential base of the ocean food web.
