Biological Oceanography
The Interaction between Marine Life and the Ocean
Because the ocean contains 99% of the living space on Earth and covers over 70% of Earth’s surface, its composition significantly impacts all life. This is true whether you live on the coast or thousands of miles away from the nearest beach. Oceanographers study the role of oceans in the big picture of Earth’s various ecosystems and the ways in which both the ocean impacts life on Earth and Earth affects life in the ocean. Oceanography can be divided into four sub-disciplines: chemical oceanography, physical oceanography, geological oceanography, and biological oceanography, the subject of this snapshot. These sub-disciplines are interrelated and closely aligned to other ocean-related fields such as marine biology, ocean engineering, atmospheric science, and marine microbiology.
Biological oceanography is the study of the ocean through the lens of marine life – how living organisms affect and are affected by ocean chemistry, physics, and geology. The goal of biological oceanography is to understand what controls the abundances, kinds, and temporal variation of organisms in the sea.[1] Biological oceanography pays particular attention to the effects of the ocean’s chemical, physical and geographic properties and how these affect the distribution and abundance of marine organisms. Biological oceanographers also examine “all forms of oceanic processes that involve living organisms . . . including processes that occur at molecular scales, such as photosynthesis, respiration, and cycling of essential nutrients, to largescale processes such as effects of ocean currents on marine productivity.”[2]
Biological oceanography is a study of extremes in both size, depth, and location. Biological oceanographers study tiny microbes and giant blue whales. Biological oceanographers study cyanobacteria blooms covering thousands of square kilometers of the ocean’s surface and hydrothermal vent colonies thousands of feet below that surface. And biological oceanographers conduct their experiments on the swaying decks of research vessels out at sea or in labs in university science buildings.[3]
Research areas that are of current interest to biological oceanographers include the following:
- Chemical and physical factors influencing distribution patterns;
- Physiological, behavioral, and biochemical adaptations to environmental variables, including natural variations in food, temperature, pressure, light, and the chemical environment;
- Food chain dynamics;
- Nutrient cycling and initial steps of chemical energy fixation; and
- Responses to the results of man’s activities in the oceans.
Biological oceanography often gets confused with marine biology. And while biological oceanography has many similarities to marine biology, they are two distinct areas of marine science. While marine biologists study the ocean’s plants, animals, and protists, biological oceanographers study marine organisms and their biological processes within the context of their natural environment.[4]

The Path to Becoming a Biological Oceanographer
From High School to Your First Job
Build a Solid Academic Foundation
Basics:
Take all available STEM-related courses (chemistry, biology, physics, computer science, algebra, geometry, calculus) offered at your high school. Take all these classes at the most advanced level possible (honors, AP). This will help you build your knowledge base in scientific theory and concepts.
Recommended:
If not available at your high school, take ocean science-related (oceanography, marine biology, marine microbiology, coastal science), chemistry-related (inorganic chemistry, biochemistry, geochemistry), and physic-related (biophysics, thermodynamics, acoustics, geophysics) classes offered online.
Keep in Mind:
Gain lab work experience through a research internship. Learn how to write for a scientific and non-scientific audience. The ability to communicate in writing cannot be overstated. Given the international nature of scientific collaboration, become fluent in a foreign language. Be a voracious reader.

What degree is right for you?
Bachelor’s Degree
A bachelor’s degree is required for all entry-level jobs, but your advancement will be limited. You should obtain a degree in oceanography or something either closely related (marine biology, marine microbiology, coastal science) or complementary (biogeochemistry, atmospheric sciences). Familiarity with lab techniques, computer modeling, and the use of scientific instrumentation is essential.
Master’s Degree
A master’s degree is highly recommended as this is where you will be able to begin to specialize your studies in biological oceanography. A master’s degree will open up more opportunities with both federal and state government agencies as well as with various companies in the private sector. In a master’s program, you will learn the theory and the practice of biological oceanography in addition to having the opportunity to engage in challenging fieldwork.
Doctoral Degree
A doctoral degree is required if you want to pursue a career as a university professor or researcher. Senior research positions with federal (NOAA, Bureau of Ocean Energy Management) and state (Environmental Protection, Fish and Wildlife) government agencies and senior project manager positions with private corporations (environmental consulting, pharmaceuticals) may require a doctoral degree. This is also true for high-level positions with nongovernmental organizations and nonprofit organizations.

Tip 1
Given the interdisciplinary nature of biological oceanography, you can still pursue a career in the field even if your school does not have a biological oceanography major. You can major in biology, chemistry, or physics.
Tip 2
Don’t just consider a school’s undergraduate offerings. Even if a school does not offer biological oceanography as a specific major at the undergraduate level, you may eventually be able to take relevant classes at the graduate level.
Tip 3
Get out in the field as soon as possible to gain real-world experience and perspective. Internships, fellowships, and research opportunities are available to college students interested in biological oceanography or other ocean sciences.
