Harvard Undergraduate Oceans is a student-driven initiative dedicated to expanding Harvard’s role in advancing ocean sustainability. While significant faculty research already exists, student involvement and cross-school collaboration remain limited. Our project connects passionate students with experts across Harvard’s ten schools to drive impactful work in three areas: Prevention (education and legal protections for marine life), Cleanup (innovative solutions to reduce plastic and fishing-net pollution), and Policy (advocating for adoption of scalable ideas globally). By raising awareness, launching interdisciplinary projects, and building partnerships with organizations like NOAA and the UN, we aim to spark measurable, lasting progress for ocean conservation.
