Dr. Rankey focuses on fundamental controls on the nature and variability of carbonate sedimentary, geomorphic, and stratigraphic systems, using Holocene systems to develop predictive understanding of carbonates in the stratigraphic record.
Dr. Rankey's research program focuses on understanding and quantifying the nature and controls on variability in surface processes, sedimentology, geomorphic forms, and early diagenesis in modern tropical marine and nearshore carbonate sedimentary systems, including evaluating the impact of global change on Earth-surface processes. To achieve these goals, his group’s research emphasizes field study of Holocene ramps, rimmed shelves, and isolated platforms, observing both process (waves, tides, etc.), product (biota, sediment and seascapes), remote sensing and GIS analysis of spatial patterns, and computer simulation modeling. In developing testable conceptual and quantitative models, these studies bear on the origin of the stratigraphic record of carbonate successions and have direct application to prediction in the geologic record, including reservoir analogs. Dr. Rankey’s experiences also include integration of geologic data with seismic interpretation, seismic modeling, and seismic attribute analysis, from regions including GOM, Southeast Asia, the Middle East, west Texas, offshore Brazil and Canada. He has also taught classes and short courses in seismic interpretation of carbonate successions, carbonate depositional systems and stratigraphy, oceanography, carbonate reservoir characterization, and field geology.
