Jon Martin’s research focuses on surface water and ground water interactions, including the quantity of water exchanged across the sediment-water interface and the chemical influence of this exchange on water quality.
Most of this research on karst aquifers has focused on the Floridan aquifer.
He is also interested in quantifying the flux of water from coastal aquifers and its significance to water quality in estuarine and coastal surface water. This work has focused mostly on Indian River Lagoon on the east coast of peninsular Florida.
And, he is currently working on the west coast of Greenland to gain a better understanding of the conditions that could lead to the collapse of continental ice sheets.
