Hundreds of years
When carbon enters the deep ocean, it can remain there for hundreds to thousands of years. This long residence time is due to the ocean's layered structure, where deep waters are less accessible to mixing with surface waters. The carbon is part of the ocean's carbon cycle, contributing to the long-term storage of carbon in the deep sea. Ultimately, processes such as upwelling and ocean circulation can eventually return this carbon to the surface, but this can take a significant amount of time.
A deep ocean trench is a deep underwater canyon. It is found at the deepest parts of the ocean. It is long, thin, and has steep sides.
Deep ocean trenches are deep slits in the middle of the ocean. The pressure inside these trenches is unbearable. long, curved valleys along the edges of the ocean basin
The carbon cycle is naturally slowest in deep ocean waters, where carbon can remain sequestered for hundreds to thousands of years before resurfacing. In these regions, carbon can be stored in deep-sea sediments, forming long-term repositories of carbon that contribute to the slow turnover of carbon in the cycle.
The carbon reservoir in the deep ocean plays a crucial role in the global carbon cycle by storing and releasing carbon dioxide over long periods of time. This helps regulate the amount of carbon dioxide in the atmosphere, which is important for maintaining Earth's climate and overall balance of carbon in the environment.

An ocean trench is a long, deep depression in the ocean. They are the result of oceanic plates sliding under one another.

A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called an ocean trench. This is caused by two plates pulling apart.
Carbon moves from the atmosphere to the ocean through a process called carbon sequestration. This can happen through physical processes such as diffusion or ocean mixing, as well as biological processes like photosynthesis by phytoplankton. Carbon dioxide in the atmosphere dissolves in the ocean's surface waters, where it can then be stored for long periods of time.
