oil spill

The National Science Foundation will spend nearly half a million dollars to help a University of New Orleans chemistry professor study sunlight and oil spills. WWNO reporter Tegan Wendland had a conversation with UNO chemistry professor Matthew Tarr.

Tarr wants to better understand how the sun breaks down oil on the water’s surface.

Maritime traffic along the Mississippi River in Louisiana is getting back to normal after three ships collided about 60 miles west of New Orleans. The Coast Guard is escorting ships between New Orleans and Baton Rouge.

The Coast Guard says a wellhead damaged earlier this week off Plaquemines Parish has been secured.

Ensign Tanner Stiehl says Wild Well Control crews secured the well shortly after a specialized barge arrived Thursday in Lake Grande Ecaille Bay, nine miles southwest of Port Sulphur.

The wellhead owned by Houston-based Swift Energy Co. was damaged Tuesday by one of the company's crewboats. Stiehl says skimmer boats have since collected more than 1,200 gallons of oily water. He says 4,880 feet of boom was set out to contain the spill and keep it out of marshes.

The Coast Guard is overseeing an offshore oil spill in Plaquemines Parish. A 42-foot vessel hit an inactive wellhead Tuesday night about nine miles southwest of Port Sulphur.
