Marine Biologist

The most romanticized science career, and the most oversubscribed.

Typical pay

$45k-$90k

How you get in

Bachelor's minimum; master's or PhD for research roles

Outlook

Very competitive; aquaculture and policy roles are more available

Marine biologists study ocean organisms and ecosystems. The field is genuinely fascinating and genuinely crowded — most positions require a graduate degree, and far more people want the job than there are jobs.

How to get in

Degree plus field experience

Duration

4 years plus internships

Cost

$40,000-$180,000

Credential

BS in marine biology, biology or ecology

  1. Complete a biology degree — a general biology degree is often more flexible than marine-specific
  2. Take every internship, REU and volunteer field position available
  3. Learn statistics, R and boat or dive certifications — these are the practical differentiators
  4. Expect to start in technician or seasonal work

Graduate degree

Duration

2-6 years after the bachelor's

Cost

$0-$60,000 — assistantships often fund it

Credential

MS or PhD

  3. Publish your work
  4. The PhD is required for principal investigator and faculty roles

Applied and adjacent careers

Duration

4-6 years

Cost

$40,000-$180,000

Credential

BS or MS plus applied specialization

  1. Target aquaculture, fisheries management, environmental consulting or marine policy
  2. These have far more openings than academic research
  3. Add GIS, regulatory or aquaculture technical skills
  4. Where most marine biology graduates actually build stable careers
