"Marine biology is the scientific study of the biology of marine life, organisms in the sea."
The study of marine organisms.
Introduction to marine biology: Overview and introduction to marine biology, including basic concepts, history of the field, and important marine habitats.
Oceanography: Study of physical and chemical properties of the ocean, including ocean currents, tides, waves, and temperature.
Marine ecology: Study of relationships between organisms and their environment in the marine ecosystem.
Marine conservation: Study of ways to protect marine ecosystems, including strategies for reducing pollution, climate change, and overfishing.
Marine biodiversity: Study of the diversity of marine species and their distribution, including how to classify, identify, and catalog them.
Marine microbiology: Study of microscopic organisms in the marine ecosystem, including viruses, bacteria, archaea, and protists.
Marine mammals: Study of marine mammals, including their biology, behavior, and conservation status.
Fisheries science: Study of commercial fishing practices and their impact on marine ecosystems, including strategies for sustainable management.
Marine biotechnology: Application of biological science to develop new products or improve existing ones, including drugs, food products, and industrial materials.
"A large proportion of all life on Earth lives in the ocean."
"The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface."
"Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and thermal vents, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic) zone."
"Marine ecology is the study of how marine organisms interact with each other and the environment."
"Marine organisms contribute significantly to the oxygen cycle."
"Shorelines are in part shaped and protected by marine life."
"Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world."
"Marine organisms are involved in the regulation of the Earth's climate."
"Many species are economically important to humans, including both finfish and shellfish."
"It is also becoming understood that the well-being of marine organisms and other organisms are linked in fundamental ways."
"The human body of knowledge regarding the relationship between life in the sea and important cycles is rapidly growing, with new discoveries being made nearly every day."
"Large areas beneath the ocean surface still remain effectively unexplored."
"The organisms studied range from microscopic phytoplankton and zooplankton to huge cetaceans (whales) 25–32 meters (82–105 feet) in length."
"Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and thermal vents, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic) zone."
