NOSAMS Graduate Student Internship Program
Two internships are awarded each year to U.S. based graduate students for research at the NOSAMS radiocarbon facility at the Woods Hole Oceanographic Institution. The internships should involve innovative application of radiocarbon measurements to an important oceanographic research problem and/or development of new techniques for radiocarbon measurement and will provide 2 to 6 weeks at NOSAMS. Available funds will cover all analytical costs (for a modest number of analyses), round-trip travel, accommodation, and subsistence while in Woods Hole, but not field work and sampling.
Candidates should submit a two-page proposal outlining the proposed work and motivation and we will begin reviewing submissions starting June 1, 2024. Please include a list of the number and type of samples to be analyzed (e.g., 5 DOC samples, 10 carbonate samples, etc), which will not count toward the 2-page limit. Proposals, the requested sample analyses, and CVs (all as pdf files) should be sent to firstname.lastname@example.org along with contact information. Proposals will be judged based on scientific soundness, relevance to capabilities and objectives at NOSAMS, novelty, and potential scientific impact. Priority will be given to collaborative research with PI’s at NOSAMS, and that show promise for follow-on projects. Internships can be used at a mutually agreed time between September 1, 2024 and August 31, 2025.
