Dr. Arne Winguth
Assistant Professor in Oceanography
Earth and Environmental Sciences
My interests are in oceanic and atmospheric dynamics and their interactions with biogeochemical cycles over a broad range of Earth history. Synthesizing complex earth system models with high-resolution paleoclimatic data is essential to the understanding of past climates, climate change, and the consequences for future climate evolution. During my Ph.D. studies at the Max-Planck-Institute (MPI) for Meteorology in Hamburg, Germany, I developed an inverse ocean general circulation model and assimilated paleoproxies into this model in order to reconstruct the ocean circulation during the last glacial maximum. I continued my paleoclimatic studies as a Research Associate at the University of Chicago. At the University of Wisconsin-Madison and here at University of Texas at Arlington, I was investigator of a NASA project and three NSF grant-funded projects. My research includes assimilation of ocean color data into an inverse three-dimensional ocean carbon cycle model, Earth system modeling for future and past climates and ocean circulation; for example, ocean anoxia at the Permian-Triassic boundary and the hot-house climate during the Paleocene Eocene Thermal Maximum.
Research Group

The oceanic and atmospheric research group is comprised of senior personnel, PhD, masters, and undergraduate students investigating changes in oceanic and atmospheric dynamics in the past, present, and future. We utilize comprehensive models developed by the National Oceanographic and Atmospheric Administration (NOAA) and the National Center for Atmospheric Research (NCAR), as well as NCAR’s supercomputing facilities. These resources are applied to paleoclimate projects, which include examining oceanic dynamics that contributed to the Permian-Triassic mass extinction event, and abrupt climate change during the Younger-Dryas as well as the Paleocene-Eocene Thermal Maximum. Research also involves exploring the urban heat island of the Dallas-Fort Worth area in relation to drought conditions, and interannual to decadal variability of the marine biogeochemical cycles.
