Dartmouth University

What you'll study

The programme is organised around an intensive research apprenticeship that combines advanced coursework, field and laboratory methods, quantitative analysis, and an original doctoral dissertation. Students normally take core and elective modules that span:

• Physical oceanography: dynamics of ocean circulation, air-sea interaction, coastal processes and wave/sea-ice dynamics.
• Chemical oceanography: biogeochemical cycles, trace elements, nutrient dynamics and pollutant transport.
• Marine biology and ecology: primary production, trophic interactions, population dynamics and ecosystem responses to change.
• Marine geology and sedimentology: seafloor processes, sediment transport and paleoceanography.
• Quantitative methods and modelling: numerical modelling of ocean systems, statistical analysis of environmental data, remote sensing and data assimilation.
• Field and laboratory techniques: shipboard sampling, autonomous platforms, high-resolution sensors, molecular methods and stable isotope analysis.

Coursework early in the programme typically establishes a strong foundation in theory and methods, followed by qualifying examinations and progression to full-time research. Students undertake substantial field campaigns and laboratory work as appropriate to their dissertation, and are expected to publish in peer-reviewed journals before graduation.

Entry requirements

Applicants should normally hold a relevant bachelor's and/or master's degree in marine science, oceanography, earth sciences, environmental science, biology, chemistry, physics, or a closely related discipline. Typical entry expectations include:

• A strong academic record demonstrating preparation for advanced research.
• Evidence of research experience: undergraduate or master's research projects, publications, conference presentations or substantial laboratory/field work.
• A clear research statement outlining proposed interests and potential faculty supervisors.
• At least two academic references that can speak to research potential and preparation for doctoral study.
• For applicants whose first language is not English, proof of English language proficiency through an approved test unless exempted.

Additional requirements such as prerequisite coursework or interviews may be requested by individual faculty or the admissions committee. The programme is selective and places particular weight on demonstrated research potential and fit with faculty expertise.

Career prospects

Graduates from a PhD in Marine Sciences pursue a wide range of careers. Common pathways include:

• Academic and research careers: postdoctoral positions and faculty roles in universities and research institutes focused on oceanography, marine ecology, geosciences and interdisciplinary environmental science.
• Government and policy roles: scientific positions in national and regional agencies responsible for fisheries, coastal management, climate and marine conservation; advisory roles for environmental policy development.
• Industry and consultancy: work with environmental consultancies, offshore energy and maritime industries, aquaculture companies, and firms developing marine sensors and data platforms.
• Non-governmental organisations and conservation: scientific leadership, programme management and advocacy for marine protected areas, restoration and biodiversity initiatives.
• Data science and private sector research: applying quantitative and modelling skills in earth-system informatics, remote-sensing companies and climate services.

The programme emphasises research communication, grant-writing and collaborative skills to prepare graduates for interdisciplinary teams and leadership roles.

Why study at Dartmouth University

Dartmouth University offers an interdisciplinary research environment with faculty whose expertise spans the major sub-disciplines of marine science, enabling cross-cutting projects that combine field, laboratory and modelling approaches. The department supports small cohorts and close faculty supervision, which fosters mentorship and tailored training plans.

Students benefit from access to modern laboratories, computational resources and partnerships that provide coastal field platforms and opportunities for shipboard and autonomous-vehicle experiments. The institution prioritises collaborative research, external funding opportunities and professional development, helping trainees build networks across academia, government and industry.

Overall, the programme is well suited to students who want rigorous disciplinary grounding together with the flexibility to pursue interdisciplinary questions about oceans and coasts and to translate research into policy, conservation and applied solutions.
