The following links include information about specific careers in Marine Biology:

The first link is to a branch of the National Oceanic and Atmospheric Administration. This site provides info about careers as well as courses you should take as a Biology major and graduate programs in Marine Biology.

Career Information by Hopkins Marine Station
The second link is a great source of information about various careers in marine fields provided by Hopkins Marine Station at Stanford University.

One of my most frequently asked questions is, “what careers are available in Marine Sciences?”

Marine Sciences include many curricular groups. Here is a list of a few specific areas of study in marine sciences:
Marine Biology
Marine Biology is the observational and experimental study of all aspects of the genetics, behavior, ecology, evolution, and physiology of marine organisms.
Biological Oceanography
Biological Oceanography examines the interactions between marine organisms and their physical and chemical environment.
Physical Oceanography
This field is concerned with how water moves and mixes in the ocean, changes in its properties, and how water carries and distributes dissolved chemicals, nutrients, plankton, and pollutants.
Marine Chemistry and Geochemistry
These disciplines investigate the chemistry of seawater; ocean circulation and mixing based on chemical and isotopic tracers; marine natural products; geochemistry of volcanic and geothermal phenomena; chemical exchanges between the ocean and the atmosphere; geochemical cycles of various key elements that make up our planet; geochemistry of meteorites; atmospheric trace gas chemistry; and paleoatmospheric composition recorded in polar ice cores, corals, and sediments.
Geology
Marine geologists specialize in examining continental geology (especially volcanology), island formation, seismology, and other aspects of the dynamics of the Earth’s crust.
Geophysics
If you excel at mathematics and physics, then you’d make a great Geophysicist. These scientists aim to understand the processes (seismic, geodetic) in the Earth and planets.
Applied Ocean Science
Applied Ocean Sciences focus on how technology can be used to explore the ocean. As an applied ocean scientist you may study marine acoustics, air-sea interaction, sediment transport and other coastal processes, optics, electromagnetics, and other aspects of physical oceanography.
Fisheries Management
Fisheries scientists study anthropogenic impacts on the sea, population structures and dynamics, short and long-term ecosystem change, and issues related to fisheries sustainability and governmental national and international management decisions.
Climate Studies
Scientists who study climate are interested in the dynamics of the ocean, atmosphere, ice caps, and terrestrial systems.
