Geoscience Seminar


Feb. 3, 2021, 4pm to 5pm

Office/Remote Location



The geoscience department weekly seminar presents:

Speaker: Benjmain Hatchett

Topic: Western U.S. dryland landscapes as recorders of weather and climate extremes. 

Landscapes in the Western U.S. preserve the signals of weather and climate extremes through sedimentary records, geomorphic indicators, or other proxies such as tree-rings. Information about the magnitude, duration, timing, and spatial extent of past drought and pluvial periods from these records provides valuable context for evaluating recent climate extremes as well as plausible atmospheric and oceanic circulation changes driving climatic change. I will share work that highlights how blending paleoclimate information with hydrologic and atmospheremodeling helps to characterize the hydroclimatic extremes of the southwestern US during several important periods (the last deglaciation, the late Holocene, and the Anthropocene), with a specific focus on how the last decade provides examples of these century to milennial-scale extremes. Ongoing work seeking to address challenges introduced by shorter-duration (minutes to seasonal) atmospheric conditions in interpreting longer period (decadal and greater) climate conditions will also be discussed.
