Climate Change in the Marine Environment
A graduate course that introduces students to the ongoing effects of climate change and variability on marine systems.
Marine Mammal Biology and Ecology

Summer block section includes field excursions with local fauna to demonstrate oceanographic observations and quantitative lab components including conservation genetics and population assessment techniques for studying populations in the wild.
Dr. David W. Johnston is an Associate Professor of the Practice of Marine Conservation & Ecology at Duke University and the Director of the Marine Robotics and Remote Sensing (MaRRS) Lab at the Duke University Marine Laboratory. Johnston holds a PhD from Duke University and received post-doctoral training at the Monterey Bay Aquarium Research Institute in California. His professional experience ranges from leading research programs for NOAA to working as an ecologist within the NGO sector. Johnston’s research program currently focuses on advancing robotic applications, platforms and sensors for marine science, education, and conservation missions. He has published extensively in top journals in the fields of conservation biology, oceanography, marine ecology and marine policy on research that spans tropical, temperate and polar biomes.
