Continuing impacts of Deepwater Horizon oil spill

Nine years ago tomorrow — April 20, 2010 — crude oil began leaking from the Deepwater Horizon drilling rig into the Gulf of Mexico in what turned out to be the largest marine oil spill in history. A long-term study suggests the oil is still affecting the salt marshes of the Gulf Coast, and reveals the key role that marsh grasses play in the overall recovery of these important coastal wetlands.

Cleaning up oil using magnets

In the future, it could be possible to remove oil spills on the surface of the ocean by using magnets. An interdisciplinary group of researchers has developed functionalized iron oxide particles that can attract any types of hydrocarbons. The magnetic particles and their shells can then be removed from the water relatively simply and in an environmentally friendly manner and can even be reused after being cleaned.
