“Lisa Welp”的意思、由来-开放百科全书

Lisa Welp is a biogeochemist who utilizes stable isotopes to understand how water and carbon dioxide are exchanged between the land and atmosphere. She is a professor at Purdue University in the department of Earth, Atmosphere, and Planetary Sciences.

Early life and education

Lisa Welp grew up in Ferdinand, Indiana. In high school, Welp participated in a program from Indiana University titled Exploration of Careers in Science where she spent 8 weeks on campus doing research for the University. She focuses her research on isotopes of oxygen-18 of CO2 and water, and she did field work in Alaska and Siberia studying the carbon cycling in the forests. Welp attained her Master of Science from the California Institute of Technology in Pasadena California in Environmental Science and Engineering in 2002. She also received her PhD from California Institute of Technology in the same field in 2006. Dr. Welp's obtained her undergraduate degree in Chemistry (minor in Geology) in 2000 from Indiana University in Bloomington, Indiana.^[1]

Career and research

Welp is currently an Assistant Professor at Purdue University in Earth, Atmosphere, and Planetary Sciences. Prior to this, she was an Assistant Project Scientist (2012-2014) and Postdoctoral Scholar (2008-2012) at the Scripps Institution of Oceanography, UCSD and postdoctoral Research Associate & Lecturer at Yale University (2006-2008).^[1]

Welp's areas of research concern stable isotope biogeochemistry, water and carbon dioxide exchange from land biosphere and the atmosphere, and boreal forest carbon cycling.^[1] In 2008, she worked with the Keeling CO₂ Lab^[2] run by Ralph Keeling, son of Charles David Keeling (see also Keeling Curve). Her work at Scripps led to greater understanding of how ENSO (El Nino Southern Oscillation) affects global shifts in primary production, due to the redistribution of moisture. Welp quantified this using δ¹⁸O-CO₂ (the isotopic shift in precipitation is transferred to respired CO₂)^[3]. Her analysis suggested that global estimates of gross primary production (GPP) were too low and revised them upwards to {{convert|150-170|Pg|tonne|lk=on}} carbon per year^[4].

Welp's collaborative research program has provided insight into how seasonal warming and drying affects ecosystem exchange of carbon in boreal forests^[5], how seasonal exchange of C between the atmosphere and biosphere has shifted over time ^[6], potentially due to increased water use efficiency, proportional to the rise in atmospheric CO₂^[7]
