Natasha Sekhon, Occidental College – Unlocking Ancient Water Signals Locked in the Geologic Record
On Occidental College Week: Hints to our climatic future could be hidden underground. Natasha Sekhon, assistant professor in the department of geology, digs in for a look. Dr. Natasha Sekhon has her training as a low-temperature geochemist and paleoclimatologist. She uses the geochemical signals preserved in speleothems (secondary cave deposits) and monitors modern cave systems…
