An international team of researchers is working with this sedimentary sequence to obtain a 500 meter record of environmental change and volcanic activity over the past 600,000 years. UMD researchers share their reflections from the recently completed MexiDrill Program, a scientific drilling program that recovered 1200 meters of lake sediment from the Lake Chalco basin, on the southern outskirts of Mexico City.

Dr. Erik Brown, Dr. Byron Steinman, and Laura Cappio, will be in their lab at the Large Lakes Observatory, 2205 East 5th Street, Room 16, on Monday, April 18, 2016, from 3 to 4 p.m. During this time, they will be available to discuss aspects of their research.

“Understanding past changes in rainfall and aridity in southwestern North America can help us to think about how rainfall patterns may be changing in the coming years” says Dr. Erik Brown, the project’s principal investigator. “This is a record of climate and environmental history from a part of the world where we don’t have a lot of data, and from a site relevant to millions of people.”

Planning for this field program began in 2008 and culminated in a 6-week field effort (working around the clock in 12-hour shifts) that concluded at the beginning of this month.
