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

Julio Sepúlveda is a unique fossil-hunter. Rather than the hard exoskeletons of ancient organisms, Sepúlveda analyzes a softer biological component, fats. 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.

Muddy waters: First mapping of Greenland sedimentation rates shows a turbulent system

Muddy waters: First mapping of Greenland sedimentation rates shows a turbulent system

A new study has measured the sediment carried by Greenland’s rivers to the ocean, with implications for marine ecosystems, carbon in the ocean, and dynamics of the coastal zone. 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.
