Time-sensitive opportunities

• PhD fellowship: At the Geophysical Institute, University of Bergen, and Bjerknes Centre for Climate Research we are looking for a person to fill a PhD position associated with Arctic Ocean 2050, a ten-year research program to advance understanding of the current state and future evolution of the Arctic Ocean.  The selected candidate will investigate how climate change affects the efficiency of the Arctic Ocean as a sink for anthropogenic carbon and is expected to take part in a 50-day long cruise to the Arctic commencing late July this year. We are looking for candidates with a solid background in marine biogeochemistry/oceanography, who are proficient in MATLAB/Python, and preferentially with some experience in marine biogeochemical data sampling, analysis and quality control.

• Graduate students at the University of Connecticut beginning in 2026. Our work will span a wide range of topics, including: Reconstructing and modeling the Earth’s past carbon cycle, Advancing our understanding of the modern carbon cycle,Exploring innovative approaches  to carbon capture and critical mineral extraction. These positions will offer the chance to work at the intersection of fundamental Earth system science and solutions for climate and sustainability challenges. Please feel free to reach out for more information or to discuss a potential fit.
• U.S. GO-SHIP is seeking to fill 6 student positions (with the CTD, LADCP, and Tracer teams) on the 2026 re-occupation of the Pacific Ocean zonal 9.5°N line P04E (Marshall Islands to Panama, ~7.5 weeks, May-July 2026). Application review will begin January 2, 2026.
• PhD opportunity at University of North Carolina at Charlotte
• Multiple fully-funded PhD position in the University of Cape Town Marine Biogeochemistry Laboratory focused on marine organic aerosols and ocean-atmosphere nitrogen cycling. The student will work collaboratively within a larger group associated with the Schmidt Sciences OBVI project entitled "Oxygen and biogeochemical dynamics along the west African margin: Processes and consequences (WAM)" and a National Research Foundation project entitled "Physical and biogeochemical drivers of marine organic aerosols in a complex coastal system". The exact project for each PhD student will be decided collaboratively based on experience and interests. Please circulate the advertisement widely. International students are welcome to apply. Please note, a MSc or equivalent is required to register for a PhD. Interested students can email katye.altieri@uct.ac.za with questions or send a CV and one page statement of interest. The application will remain open until filled.
• Dr. Wei-Jun Cai, from the School of Marine Science and Policy at the University of Delaware, is seeking two doctoral students to join his research group. Research topics include ocean uptake of anthropogenic carbon, ocean acidification (OA), and marine carbon dioxide removal (mCDR). Interested students are encouraged to contact him at wcai@udel.edu
