The hard science of soft substances: Julio Sepúlveda uses lipids to decode ancient ecosystems

The hard science of soft substances: Julio Sepúlveda uses lipids to decode ancient ecosystems

He looks at the distribution of organic molecules in nature from soils and sediments to lakes and the ocean, with a focus mostly on lipids, the molecular constituent of fat. He uses this data to not only reconstruct ancient environments but also to contribute to predictions for how our current climate might respond to similar environmental conditions.

Led by INSTAAR researchers and published today in Nature Geoscience, the study is the first to quantify in detail the concentrations of sediment in rivers flowing from Greenland to the sea.
