UD researchers studying ‘fingerprint’ left on seafloor by Hurricane Sandy

Beneath the 20-foot waves that crested off Delaware’s coast during Hurricane Sandy, thrashing waters reshaped the floor of the ocean, churning up fine sand and digging deep ripples into the seabed. Fish, crustaceans and other marine life were blasted with sand as the storm sculpted new surfaces underwater.

UD scientists cued up their instruments to document the offshore conditions before, during and after Sandy’s arrival to scrutinize the differences and better predict the environmental impact of future storms. (more…)

A new study provides a composite picture of the environmental distribution of oil and gas from the 2010 Deepwater Horizon spill in the Gulf of Mexico. It amasses a vast collection of available atmospheric, surface and subsurface chemical data to assemble a “mass balance” of how much oil and gas was released, where it went and the chemical makeup of the compounds that remained in the air, on the surface, and in the deep water.

The study, “Chemical data quantify Deepwater Horizon hydrocarbon flow rate and environmental distribution,” is published online in the journal Proceedings of the National Academy of Sciences USA. (more…)
