Oceanographer Oceanographers are also important in the filed of exobiology.
Oceanographers are scientists who study the ocean and the organisms in the ocean.
Jobs which they often perform are doing testing on the compostion of the ocean in particular areas, and the effects that the environment have on the organisms in it. In exobiology, oceanographers study deep sea hydrothermal vents and the environment surrounding them. Testing is done on the chemical composition of the water, to see if, and how, organisms are able to survive. Often, oceanographers work closely with marine biologists and chemists when conducting research. When the planets and their moons are being observed to determine if life might be possible on them, it is an astronomer who is looking through the telescope.
