Pelagic marine systems regulate the global climate, contribute to the water cycle, maintain biodiversity, provide food and energy resources, and create opportunities for recreation and tourism. [48] Economically, marine systems support billions of dollars worth of capture fisheries, aquaculture, offshore oil and gas, and trade and shipping.
Today, marine species range in size from the microscopic phytoplankton, which can be as small as 0.02–micrometres; to huge cetaceans like the blue whale, which can reach 33 m (108 ft) in length. [5] [6] Marine microorganisms have been variously estimated as constituting about 70% [7] or about 90% [8] [1] of the total marine biomass.
Marine biology is a branch of biology. It is closely linked to oceanography, especially biological oceanography, and may be regarded as a sub-field of marine science. It also encompasses many ideas from ecology. Fisheries science and marine conservation can be considered partial offshoots of marine biology (as well as environmental studies).
