Dr. Turner's research program is focused on several aspects of marine plankton ecology. Included are long-term monitoring studies of coastal plankton (bacterioplankton, phytoplankton, zooplankton and ichthyoplankton) and water quality (nutrients, chlorophyll, temperature and salinity) in Buzzards Bay (since 1987) and (phytoplankton and zooplankton) Boston Harbor, Massachusetts and Cape Cod Bays (since 1992); studies of the role of zooplankton grazing on bloom development and food-web transport of toxins from harmful algal blooms (red tides) in the Gulf of Maine; and studies of the reproductive success of marine copepods in relation to their diets in the Mediterranean Sea (in collaboration with Italian investigators).

Students have been, and continue to be, involved in these studies, and several papers have been coauthored with students or former students (list appended below). A variety of resources are available for, and used in, these studies. Included are Turner's laboratories on both the main campus of UMass Dartmouth, and at the School of Marine Science and Technology (SMAST), various light microscopes, a scanning electron microscope, an autoanalyzer for nutrient analyses, a fluorometer for chlorophyll analyses, and a 50 foot-long coastal research vessel. Red tide studies in the Gulf of Maine have been refunded for a period of 5 years, and a series of major research cruises, on larger research vessels from Woods Hole Oceanographic Institution, will commence in spring and summer of 2007.
