Elisabeth Sikes

Elisabeth Lynn Sikes is an American geoscientist who is a professor at Rutgers University. Her research considers carbon cycling. She was awarded the 2022 Scientific Committee on Antarctic Research Medal for Excellence in Research.

Early life and education Sikes was an undergraduate student at Wesleyan University, where she graduated cum laude in environmental sciences. She moved to the University of North Carolina at Chapel Hill for graduate studies. (WHOI) in the MIT/WHOI Joint Program. Her doctoral research on the refinement of techniques to estimate paleotemperatures. She studies circulation in the Southern Ocean, and how those processes trap and release carbon dioxide over glacial timescales. As part of these efforts, she studies temperature changes in the oceans around New Zealand using biomarkers and foramiferally estimates.

Sikes is also interested in the sources and sinks of terrestrial carbon in modern environments over shorter time scales. For these studies, she makes use of isotope analysis. She investigated how useful the Uk-37 index was for estimating paleotemperatures and predicting sea surface temperatures. This included studying whether the 14C ages of alkenones could be used to estimate paleotemperature, as lateral transport can cause these molecules to be several thousand years older than foraminifera found in the same deposit. 2018 Rutgers University Teaching Excellence award 2020 American Geophysical Union Cesare Emiliani Lecture Paleoceaongraphy/Paleoclimatology and Ocean Sciences sections Award 2022 Scientific Committee on Antarctic Research Medal for Excellence in Antarctic Research
