Four WHOI Scientists Contribute to Comprehensive Picture of the Fate of Oil from Deepwater Horizon Spill

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…)

Scientists Discover Fossil of Giant Ancient Sea Predator

Paleontologists have discovered that a group of remarkable ancient sea creatures existed for much longer and grew to much larger sizes than previously thought, thanks to extraordinarily well-preserved fossils discovered in Morocco.

The creatures, known as anomalocaridids, were already thought to be the largest animals of the Cambrian period, known for the “Cambrian Explosion” that saw the sudden appearance of all the major animal groups and the establishment of complex ecosystems about 540 to 500 million years ago. Fossils from this period suggested these marine predators grew to be about two feet long. Until now, scientists also thought these strange invertebrates-which had long spiny head limbs presumably used to snag worms and other prey, and a circlet of plates around the mouth-died out at the end of the Cambrian.

Three Year Investigation of Military Munitions Sea Disposal Site Completed

The University of Hawaiʻi at Mānoa’s School of Ocean Earth Science and Technology (SOEST) completed a three-year long investigation of Sea Disposal Site Hawaiʻi Number 5 (HI-05), a deep-water military munitions disposal site in U.S. coastal waters approximately 5 miles south of Pearl Harbor, Oʻahu, Hawaiʻi.
