Ken Sebens conducts research on benthic populations and communities in both temperate and tropical locations. One project is an investigation of community and population dynamics, and long-term change in rocky subtidal habitats in Massachusetts. This project has been funded by NSF since 1979, facilitating one of the most extensive long-term studies of coastal marine communities in the world, and will be continued in collaboration with researchers at Northeastern University. He will also initiate new research on the rocky subtidal communities of the San Juan Islands. Dr. Sebens has had over 30 years experience as a diving scientist, including six one to two week missions living and working in the underwater laboratories “Hydrolab” and “Aquarius”, located on Caribbean coral reefs. His research on coral ecology has focused on the diverse sources of nutrition for reef corals, and the influence of hydrodynamics on coral particle capture and nutrient uptake from seawater, calcification and growth rate (NSF, NOAA funding since 1985). These studies have taken him to many Caribbean reef locations including Jamaica, St. Croix, Belize, and Bermuda. He also spent a sabbatical year in Australia working on the Great Barrier Reef, while based in Townsville and Lizard Island.
