Here’s a nice look at how the same information, presented in two different ways, can produce drastically different takes on news.

The fourth anniversary of the blowout on the Deepwater Horizon oil rig, which triggered an oil spill that dumped billions of barrels of oil into the Gulf of Mexico, is on Sunday.

BP announced Tuesday that active cleanup of the Gulf Coast after the accident was over:

Active Shoreline Cleanup Operations from Deepwater Horizon Accident End

The U.S. Coast Guard today ended patrols and operations on the final three shoreline miles in Louisiana, bringing to a close the extensive four-year active cleanup of the Gulf Coast following the Deepwater Horizon accident. These operations ended in Florida, Alabama and Mississippi in June 2013.

“Reaching this milestone is the result of the extraordinary efforts of thousands of people from BP, local communities, government agencies, and academic institutions working together,” said John Mingé, Chairman and President of BP America. “Immediately following the Deepwater Horizon accident, BP committed to cleaning the shoreline and supporting the Gulf’s economic and environmental recovery. Completing active cleanup is further indication that we are keeping that commitment.”

Big news, right? The active cleanup is over.

Oh, and also on Tuesday, the U.S. Coast Guard put out this announcement:

Different tactics, but Deepwater Horizon Response is far from complete

NEW ORLEANS – The Coast Guard federal on-scene coordinator (FOSC) for the Deepwater Horizon Response completed the transition to the “Middle Response” (“Middle R”) process today and opened active National Response Center (NRC) cases for three miles of coastline in Louisiana.

“Our response posture has evolved to target re-oiling events on coastline segments that were previously cleaned,” said Capt. Thomas Sparks, the FOSC for the Deepwater Horizon Response. “But let me be absolutely clear: This response is not over—not by a long shot. The transition to the Middle Response process does not end clean-up operations, and we continue to hold the responsible party accountable for Deepwater Horizon cleanup costs.”

That “Middle R” term refers to having dedicated teams ready to quickly respond to any residual oil, according to the Coast Guard.

The cleanup isn’t the only thing still being managed four years after the catastrophic spill. As the Washington Post’s Steve Mufson explained in February, there is also the still-massive legal thicket:

The London-based oil giant is mired in litigation in federal courts in New Orleans. No longer apologetic, BP has stiffened its spine. It has filed new motions and countersuits, taken out a slew of full-page ads in newspapers (including The Washington Post) and enlisted the British ambassador to express concerns to the Obama administration over how aggrieved the company feels.

In addition, a study last month found that the oil spill had dire implications for tuna and amberjack fish in the Gulf.
