Biological Oceanographers study marine ecosystems, biological process of aquatic plants and animals. They research about plants and animals living in oceans, studies about their natural environment, take trips into ocean, perform experiments, collect data, and keep track of the activities of aquatic animals and plants.
Physical Oceanographers use satellite technology as it helps them to study the movement of the water, and the forces that cause motion, such as winds, waves and tides. They also study the interaction of ocean with land, atmosphere, weather, climate, water density, temperature, salinity, underwater formations and seafloor. They seek to understand why, where and how water moves, on all space and time scales. Physical Oceanographers requires to use the combination of theory, observations and experiments to study in detail.
Geological Oceanographers use remote sensing technology to map the ridges and valleys. They study the formations, composition and history of the seafloor. They examine sediment characteristics such as size, shape, color, weight, age, chemical characteristics, origin, distribution and transport in detail. Also, they closely work with biologists and chemical oceanographers to learn more about historical climate records, animals and plants life by examining sediment.
Ocean contains many chemical compounds, elements, gases, minerals, organic and particulate matter. Chemical Oceanographers studies formation of seawater, seafloor sediments, relationships between chemical compounds, how chemical inputs to the ocean affect it, how the chemistry of the ocean is affected by the biological, geological, and physical factors. They also study the impact of pollutants when they interact with seawater and marine life.
