Biography
I work on the water and carbon cycles in terrestrial environments. My work includes studying the response of terrestrial landscapes to changes in climate using modeling approaches, geochemical measurements, and field observations. I also work on the characterization and quantification of lithium deposits in lacustrine basins and enhanced weathering strategies for carbon dioxide removal.
In cities like Providence that have a long industrial history, heavy metals often end up in the waterways. A recent episode of the Possibly Podcast interviewed DEEPS Professor Dan Ibarra to learn how this happens, and what it means for the city’s residents.
A recent study utilizes ancient plant waxes preserved in sediments from two Utah lakes to investigate ancient climate history. Assistant Professor Dan Ibarra noted that a key reason for analyzing the hydrogen isotopes is to compare the climate patterns revealed by the plant wax to the patterns predicted by current climate models.
DEEPS Assistant Professor Dan Ibarra and Postdoc Gavin Piccione are co-leaders on a collaborative research project funded by the National Science Foundation to examine how climate behaved in past climates when large lakes existed in the Mojave Desert.
A recent paper co-authored by Assistant Professor Daniel Ibarra supports the hypothesis of a negative feedback that limits atmospheric carbon dioxide decline during glacial periods.
Assistant Professor Dan Ibarra, undergraduate alumnus Jonah Bernstein-Schalet, former Postdoctoral Researcher Evan Ramos, and graduate student Sebastian Munoz are coauthors on a recent publication in JGR Biogeosciences. Their research looks into CO2 emissions from headwater streams, comparing chemical signatures of river water samples taken from an Oregon watershed with both very steep and very shallow-sloping rivers. "Results from this study may impact our estimates of how rivers move carbon across the earth's surface and exchange carbon dioxide with the atmosphere."
