Deeper and larger than any of the trenches in the list above is the Bentley Subglacial Trench in Antarctica, at a depth of 2,540 m (8,330 ft). It is subglacial, covered permanently by the largest glacier in the world. Therefore, it is not included in any list on the page. If the ice melted it would be covered by sea.
An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation.
The trend of Qiandao Lake's transformation from mid mesotrophic to mesotrophic, the polluting elements are heavy metals, nitrogen, phosphorus and organic matter, cages and cruise ships; (up to 10 meters underwater) the temperature changes greatly, with an average of 28.2 °C-24.4 °C, and the water temperature is mostly maintained at a ...

Drivers, processes, and impacts of sinking cities [1]. Sinking cities are urban environments that are in danger of disappearing due to their rapidly changing landscapes.The largest contributors to these cities becoming unlivable are the combined effects of climate change (manifested through sea level rise, intensifying storms, and storm surge), land subsidence, and accelerated urbanization.

It is predicted that by 2100, sea levels will have risen by 1–3 metres as a result of global warming, and by 2050 sea level rise is estimated to impact 90% of the world's coastal cities. [22] Theorists who support ocean colonization hope to face the issue and provide a solution for groups and nations worldwide that are most at risk. [22]
It covers an area of ca. 40,000 square meters (10 acres). Underwater excavations have uncovered remnants of rectangular houses and a well. The site was covered by the eustatic rise of sea levels after the end of the last Ice Age. It is assumed that the contemporary coastline was about 1 km (a half-mile) west of the present coast.
Permafrost temperature profile. Permafrost occupies the middle zone, with the active layer above it, while geothermal activity keeps the lowest layer above freezing. The vertical 0 °C or 32 °F line denotes the average annual temperature that is crucial for the upper and lower limit of the permafrost zone, while the red lines represent seasonal temperature changes and seasonal temperature ...
