Not every marine biologist immerses herself in water, but those who do may use either simple snorkels and fins, or complex closed-circuit underwater breathing apparatuses, which have "rebreathers" to prevent the more common open circuit gear's stream of water-disturbing air bubbles. Marine biologists may find that simple tools like nets, bags and buckets play a crucial role in sample collection techniques.
Depending on what she's studying, a marine biologist may be able to just dip a bucket into the water to scoop plankton or may have to use a net to snare an elusive fish. Other tools for collecting samples could include traps for creatures, or water samplers for studying microscopic water organisms. Some marine biologists may rely on expensive underwater photo and video cameras to capture footage of creatures too large to "take home" to the lab. Video cameras also the examination of how creatures interact with the natural environment.
Sometimes biologists even attach cameras to the creatures. Remote-controlled equipment may even keep her nice and dry while the camera does the underwater work.
Scientific definitions for marine Relating to the sea. Relating to a system of open-ocean and unprotected coastal habitats, characterized by exposure to wave action, tidal fluctuation, and ocean currents and by the absence of trees, shrubs, or emergent vegetation.
Key skills for oceanographers Patience. A logical and independent mind. Meticulous attention to detail. Excellent IT skills. An oceanographer studies the ocean. Oceanography covers a wide range of topics, including marine life and ecosystems, ocean circulation, plate tectonics and the geology of the seafloor, and the chemical and physical properties of the ocean.
Both comets and asteroids can contain ice. And if, by colliding with Earth , they added the amount of material some scientists suspect, such bodies could easily have delivered oceans' worth of water.
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided. Oceanographers may work on ships or in laboratories on land.
Some work for private companies. Most work for research institutes or government agencies, or hold teaching and research jobs in colleges and universities. Oceanographers who conduct research study many aspects of the sea.
Niskin bottle. A Niskin bottle is a plastic cylinder with stoppers at each end in order to seal the bottle completely. The water collected by Niskin bottles can be used for studying plankton or measuring the physical characteristics of the sea. What tools do marine biologists use?
