Dennis V. Kent

Dennis V. Kent is an American geologist and geophysicist who is a Doherty Senior Scholar at Lamont–Doherty Earth Observatory of Columbia University and a Board of Governors Professor Emeritus at Rutgers University. His research focuses on paleomagnetism, geomagnetism, rock magnetism, and their application to geologic problems, including geologic time scales, paleogeography, ancient climate, polar wander, and the long-term carbon cycle.

Early life and education Kent was born in Prague, Czech Republic. He came to the United States in 1953. He wed Carolyn Cook in 1971 and they have a daughter and a grandson.

He joined the adjunct faculty in the Department of Earth and Environmental Sciences at Columbia University in 1981, becoming adjunct professor in 1987, a position he held until 1998.

Research Kent's research focuses on paleomagnetism, geomagnetism, and rock magnetism, applying these tools to problems in chronostratigraphy, paleogeography, and paleoclimatology. He has authored or co-authored more than 330 peer-reviewed publications, which have garnered over 50,000 citations and an h-index of 104 according to Google Scholar.

In 1992, he and Steven C. Cande published a geomagnetic polarity time scale for the Late Cretaceous and Cenozoic based on marine magnetic profiles. Cande and Kent revised the calibration of the time scale in 1995 using new radioisotopic dates and magnetic anomaly spacings.

Kent, Paul E. Olsen and William K. Witte also published a detailed geomagnetic polarity sequence for the Late Triassic and earliest Jurassic based on drill cores from the Newark rift basin in eastern North America.

In a 2020 paper with Giovanni Muttoni, he examined the possible relationship between changes in the configuration of Pangea, silicate weathering and the Late Paleozoic Ice Age.

In 2010, Kent and Edward Irving published a study of the Triassic and Jurassic apparent polar wander path for North America. The study examined the effects of inclination error in sedimentary rocks and discussed implications for tectonic reconstructions of the North American Cordillera.

In 2021, Kent and Lars B. Clemmensen studied the northward dispersal of sauropodomorph dinosaurs from Gondwana to Greenland during the Late Triassic. They suggested that a decline in atmospheric carbon dioxide levels around 215–212 million years ago may have reduced climatic barriers to this dispersal.

Kent has also studied the timing of volcanism associated with the Central Atlantic Magmatic Province and its relationship to the end-Triassic mass extinction.
