UD scientists are addressing ocean issues in environments all around the world, from the icy seas of the Antarctic to the mid-Atlantic coast. You can learn all about those projects by taking a free guided tour of our world-class research complex in Lewes. Offered Tuesday and Friday mornings this summer, the walking tours showcase various research projects being conducted on marine and coastal environments and on the different organisms that inhabit them. A short video kicks off the tours, which are suitable for adults and children ages 12 and up. Reservations are required 24 hours in advance. Call 302-645-4346.
