Dr John M Klinck is currently a professor in the Department of Ocean, Earth and Atmospheric Sciences at Old Dominion University in Norfolk, VA, USA. His major interest is quantitative assessment of ocean physical and biological processes through the techniques of numerical models of these processes as well as analysis of observations of various kinds.
His most recent research has focused on the physical processes associated with water circulation on the continental shelf around Antarctica with emphasis on the west side of the Antarctic Peninsula and the Ross Sea. Each of these regional studies considers the exchange of Circumpolar Deep Water across the shelf break, which for Antarctic shelves is the source of heat and nutrients. These studies analyze the small-scale processes associated with ocean variability (eddies and tides) and the interaction of the flow with the rugged bottom topography leading to water exchange across the shelf break. These model calculations estimate basal melt, a globally important quantity, in various ice shelves which are common around Antarctica. Model simulations are compared to ship-based and marine mammal-based observations.
Several of these regional numerical models have been extended to include biological variables (nutrients, micro-nutrients, algae) and drifting particles (larvae) to diagnose primary production and the growth and transport of krill. Additionally, tracers are included in the model to track various water masses or meltwater.
He is also active in creating numerical models representing the growth, reproduction, and genetic variability of oysters, clams and other bivalves. One recent interest is the transmission and development of diseases in sessile marine invertebrates.
