Research Description

Lynn Ingram received her B.S. and her M.S. in geology from UCLA, the first in 1984, the second in 1989 and then her Ph.D in Geology from Stanford University in 1992.

Her current research focusses on stratigraphy with strontium isotopes and paleoclimatic and paleo-environmental reconstruction in aquatic environments (estuarine, lacustrine, riverine, and marine) using sedimentological, paleontological, and geochemical data (primarily stable isotopes).

She has assessed changes in climate in California over the past several thousand years using geochemical analyses of sediment cores from San Francisco Bay and surrounding marshes, as well as stratified shellmounds from San Francisco Bay and Santa Barbara Basin. She has also studied lake sediments from California and the Gulf of California.

Her expertise includes sedimentary geochemistry, specifically using environmentally-sensitive isotopic tracers (87Sr/86Sr, 18O/16O,13C/12C, and 14C/12C) to document changes in salinity, streamflow, temperature, ocean circulation, and coastal upwelling.

The state, the drought and El Niño: It’s complicated

Just last year, researchers were saying there was no end in sight for California’s recent drought. But things are looking up. El Niño has swept into the Golden State and is breathing life back into the area.

Why state’s water woes could be just beginning

As 2013 came to a close, the media dutifully reported that the year had been the driest in California since records began to be kept in the 1840s. UC Berkeley paleoclimatologist B. Lynn Ingram didn’t think the news stories captured the seriousness of the situation.
