Marine biology - Wikipedia

Biological OceanographyMarine HabitatsMarine LifeSubfieldsDistribution FactorsHistoryFurther ReferencesExternal LinksMarine 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. Biological oceanography mostly focuses on the microorganisms within the ocean; looking at how they are affected by their environment and how that affects larger marine creatures and their ecosystem. Biological oceanography is similar to marine biology, but it studies ocean life from a different perspective. Biological oceanography takes a bottom up approach in terms of the food web, while marine biology studies the ocean from a top down perspective. Biological oceanography mainly focuses on the ecosystem of the ocean with an emphasis on plankton: their diversity (morphology, nutritional sources, motility, and metabolism); their productivity and how that plays a role in the global carbon cycle...Get price
