RAMPS met with DOI Office of Wildland Fire, US Customs and Border Patrol, and US Fish & Wildlife Service staff at Buenos Aires National Wildlife Refuge in southern AZ last November. The group is developing tools to reduce wildfire risk, conserve wildlife habitat and natural resources, and increase safety and security of border operations.

USGS scientist Summer Praetorius of the Geology, Minerals, Energy, & Geophysics (GMEG) Science Center collects samples from an ocean sediment core in the Pacific Ocean Paleoclimatology Lab at Menlo Park, CA. The sediment core is from Tanner Basin, located about 200 miles due west of San Diego in the eastern Pacific Ocean.
