What is the deep ocean ecosystem?
The term ‘deep ocean’ typically describes any marine ecosystem located at depths higher than 500 m. This environment is characterised by an elevated hydrostatic pressure, an average temperature of 2–4 °C, the absence of sunlight and the scarce availability of organic food.
