Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system. Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is Oikos (oικoσ), meaning ‘house’ or ‘habitat’ in Greek.
Marine biology can be contrasted with biological oceanography. Marine life is a field of study both in marine biology and in biological oceanography . Biological oceanography is the study of how organisms affect and are affected by the physics , chemistry , and geology of the oceanographic system .
Thermohaline circulation. Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
[2] [3] Marine life is studied scientifically in both marine biology and in biological oceanography. By volume, oceans provide about 90% of the living space on Earth, [4] and served as the cradle of life and vital biotic sanctuaries throughout Earth's geological history.
Sea water is 827 times denser than air.. Due to the higher density of sea water (1,030 kg m −3) than air (1.2 kg m −3), the force exerted by the same velocity on an organism is 827 times stronger in the ocean.
In biological oceanography, new production is supported by nutrient inputs from outside the euphotic zone, especially upwelling of nutrients from deep water, but also from terrestrial and atmosphere sources (as opposite to regenerated production, which is supported by recycling of nutrients in the euphotic zone).

In biological oceanography, critical depth is defined as a hypothetical surface mixing depth where phytoplankton growth is precisely matched by losses of phytoplankton biomass within the depth interval. [1] [note 1] This concept is useful for understanding the initiation of phytoplankton blooms.
