Image Of the Day caption:
WHOI postdoctoral scholar Sam Mu?oz prepares the small research vessel Arenaria for launch in Big Lake, Missouri, this spring. Mu?oz used the tripod in the foreground to extract sediment cores from the bottom of Midwestern lakes and rivers, as part of a project to reconstruct the flood history of the Mississippi River and its major tributaries. When rivers flood and overflow their banks, mud and sand is carried in river water and gets deposited in nearby lakes and wetlands. Mu?oz can find their traces layered in the cores he extracts. He can date those layers to map the history of floods across a river basin.
