Project Grant 2052633

This National Science Foundation Project Grant, awarded under the Geosciences program (CFDA 47.050), provides $190,000 to resolve high-resolution paleoclimate variability in subarctic Canada across the mid-Pleistocene transition and interglacial periods of the last 1.5 million years. The postdoctoral researcher will characterize past interglacial climate variability using rare subarctic speleothems, combining novel geochronological techniques, micro-analytical methods, and imaging to reconstruct high-latitude North American paleoclimate records. The records will investigate climate variability during even warmer past interglacials to resolve broad temperature changes across different interglacial stages and provide snapshots of high-frequency hydroclimate variability. Professional development and community outreach are also supported.
