Despite the growing urgency of addressing climate change and its associated environmental challenges, undergraduate enrollment in geoscience programs has declined. This trend underscores the need for undergraduate institutions to develop more effective and accessible pathways that encourage students to pursue careers in the geosciences. To achieve this, Eckerd College, with funding support from the National Science Foundation, has collaborated with the University of South Florida College of Marine Science, the United States Geological Survey, the Florida Institute of Oceanography, and other private partners to develop a curriculum aimed at increasing undergraduate engagement in the geosciences. The Scientists at Sea (S-A-S) program employs a multidisciplinary approach to recruit, educate, and train future geoscientists by providing foundational knowledge, practical skills, and applied research experience. As part of the program, students take a lecture-driven deep dive into the history of the Gulf and then participate in ongoing research cruises in the Northern Gulf, contributing to long-term monitoring of the Deepwater Horizon oil spill, collecting samples and data for additional scientific projects. Complementing these valuable field experiences, the S-A-S course sequence includes training in proposal development, project planning, science communication, and conference presentation. To date, three cohorts consisting of around 25 students and four peer mentors have participated. This presentation outlines the S-A-S program framework at Eckerd and offers a model that other undergraduate institutions may adopt in designing their own geoscience curricula.
