Coast Day

Coast Day

Celebrating five decades of coastal, marine and environmental science

Join us on Sunday, October 4 for Coast Day


Coast Day is the annual flagship event celebrating the teaching, research and outreach of the College of Earth, Ocean and Environment at the University of Delaware. Learn how UD students, faculty, staff and community partners are improving our understanding of the environment and serving coastal communities.

Now in its 50th year, Coast Day draws attendees to UD's Lewes campus to explore cutting-edge science through hands-on activities, live demonstrations, lab and ship tours, and more. Coast Day also includes live performances, a diverse food court, and a range of experiences for every age.

We look forward to seeing you at Coast Day on Sunday, October 4!
