Gulf of Mexico

The Trump administration is proposing dramatic changes to policies on offshore leasing for oil and gas, opening the door to radically expand drilling in waters that were protected by the Obama administration.

It's the "largest number of lease sales ever proposed, " Interior Secretary Ryan Zinke told reporters. The proposed plan to sell offshore drilling leases in the Atlantic, Pacific and Arctic over a five-year period was detailed Thursday.

It has become a rite of summer. Every year, a "dead zone" appears in the Gulf of Mexico. It's an area where water doesn't have enough oxygen for fish to survive. And every year, the National Oceanic and Atmospheric Administration commissions scientists to venture out into the Gulf to measure it.
