The Fosa de Calypso is a deep underwater trench located in the western part of the Caribbean Sea. It is part of the larger Cayman Trench, which is known for its significant depth and geological features. The trench is named after the research vessel Calypso, which was used by the famous oceanographer Jacques Cousteau for marine exploration. This trench plays a crucial role in the ocean's ecosystem, providing habitat for various marine species. Its depth and unique conditions make it an area of interest for scientists studying oceanography and marine biology. The Fosa de Calypso is also significant for understanding tectonic activity in the region.
