His research is focused on the structural and tectonic analysis of rift and transform plate boundaries. investigations of contental extensional terranes, rifted continental margins, Iceland and mid-ocean ridges provide overlapping perspectives on crustal accetion across a spectrum of environments dominated by magmatic construction and mechanical deformation. He uses outcrop-scale data collected from a wide range of research approaches including field geology, drone imaging, and seafloor investigations using submarines, ROV’s, and AUV’s to constrain larger-scale tectonic processes. The cross-pollination of data and processes from different environments helps to provide a more comprehensive understanding of crustal accretion on Earth and other planetary bodies.

Prof. Karson is also one of the leaders of the . The lave pours promote and allow for scientific experiments, artistic creations, education and outreach to the Syracuse University and City communities.

Christopher A. Scholz /faculty-experts/christopher-a-scholz/ Fri, 17 Feb 2017 21:27:18 +0000 /?post_type=faculty-experts&p=114513 Dr. Scholz’s research focuses on recovering records of past climate from lake basins, and on the sedimentary basin analysis of extensional systems, with emphasis on lacustrine basins. Current research efforts are concentrated on the large lakes of tropical Africa and the Finger Lakes of Central New York. Lake basins contain some of the highest quality archives of climate change on the continents, and new drill core records from the low-latitude lakes of Africa are revealing new details about the Pleistocene record of climate change.

The world’s large rift valley lakes are outstanding laboratories for understanding the interaction of tectonic, climatic, and depositional processes, and are particularly useful for developing models for hydrocarbon exploration in ancient rift systems. These large, deep lakes contain thick accumulations of sediment dating back millions of years, and are among the best places on the continents for reconstructing past climates. Recent field programs have involved scientific drilling in tropical lake basins, the recovery of high-resolution sediment cores from lakes, and the imaging of sedimentary lake basins at various scales, using seismic reflection datasets techniques.

Linda Ivany /faculty-experts/linda-ivany/ Fri, 17 Feb 2017 20:44:50 +0000 /?post_type=faculty-experts&p=114496 Professor Ivany’s work fits broadly into the fields of earth history and paleobiology.  Most research projects lie at the intersection of marine paleoecology and paleoclimate, and relate to how ecosystems and their component taxa evolve and respond to changes in the physical environment on a variety of temporal and spatial scales.  Many studies incorporate the stable isotopic chemistry of accretionary skeletal hard parts to reconstruct records of life history, seasonality, and environment in deep time.

She has particular interest in the biotic and climatic evolution of the early Cenozoic, with longstanding projects in the molluscan records of the US Gulf Coastal Plain and Antarctica.  Work on the chemistry of Permian and Cretaceous bivalves relates to paleoseasonality and the oxygen isotopic composition of seawater.  Research on growth rate and lifespan explores the evolution of life histories in deep time, including the evolution of extreme longevity.  Other interests include the long-term dynamics of ecological assemblages, including the proposed pattern of coordinated stasis, and how the architecture and composition of the sedimentary record influence metrics of Phanerozoic diversity.
