The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
The "snowflakes" grow over time and may reach several centimetres in diameter, travelling for weeks before reaching the ocean floor. However, most organic components of marine snow are consumed by microbes , zooplankton and other filter-feeding animals within the first 1,000 metres of their journey, that is, within the epipelagic zone.
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [1] The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.
The Atlantic silverside (Menidia menidia), also known as spearing in the northeastern United States, is a small species of fish that is one of the most abundant fish species present in estuarine habitats along the Atlantic coast of North America. [3] It is a common subject of scientific research because of its sensitivity to environmental ...
The pass starts from just northeast of the island of Newfoundland over the North Atlantic Ocean to central Africa, over South Sudan. The Atlantic Ocean is the second-largest of the world's five oceanic divisions, with an area of about 85,133,000 km 2 (32,870,000 sq mi). [2]
Scientists exploring a submerged mountain range in the Mid-Atlantic stumbled onto something they can’t explain: An organized series of holes punched in the floor of the Atlantic Ocean.
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
