Argentine Abyssal Plain

The Argentine Abyssal Plain is a submarine plain located in the Atlantic Ocean, east of Argentina. It is part of the larger Argentine Basin and reaches a maximum depth of 20,381 feet (6,212 meters).1

Abyssal plains are vast, flat seafloor areas found at depths between 3,000 and 6,000 meters (10,000 to 20,000 feet). They are typically adjacent to continents and are formed by the accumulation of land-derived sediment that smooths out irregular topography. These plains are most common in the Atlantic Ocean and are characterized by uniform environmental conditions, including low temperatures and high pressure. The sediment on abyssal plains is primarily composed of microscopic remains of plankton and other marine organisms, along with land-derived materials transported by turbidity currents.23
