Greta Wells is conducting her Master’s research on jökulhlaups in Iceland. Specifically, she’s working to reconstruct a Holocene history of these glacial outburst floods along a river channel that drains the country’s largest ice cap. To find clues of past floods, she studies geomorphologic features and analyzes rock samples and sediment cores. Greta is pictured here taking a sediment core from a lake perched at 3000 meters in the Colombian Andes during a separate summer research project on paleoclimate reconstruction. The next stop for this coring equipment (and Greta) is Iceland!
