A post from Aaron Hartmann, a marine biologist, describes some of diverse of ocean-related jobs out there:
Fisheries observers: Want to improve your sea legs? Fisheries observers live aboard fishing boats and ensure that the animals being harvested are big enough and not in numbers exceeding legal catch limits. Their work is critical for managing ocean harvesting in order to ensure that we don’t drive species to extinction.
Oceanographer: Open-ocean ecosystems, deep-sea communities, hydrothermal vents, oxygen minimum zones, garbage patches, currents, winds, and global seawater circulation—oceanographers do it all (not surprising given their title).
Engineers: Submarines, remote sensing buoy systems, remotely operated underwater vehicles and ocean-scanning satellites—engineers make them all. Thanks to their work, we are constantly going deeper and farther, discovering more about the ocean’s unknowns.
Aquarist: The survival of animals that live in public aquariums worldwide depends on professional aquarists. These people know more about what makes marine critters happy than anyone else, and I know this from experience. Working alongside aquarists at Birch Aquarium, I’ve learned an incredible amount about corals over the past few years.
