Did BP Oil Kill This Whale?


Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.

Two and a half years have passed since the disastrous oil spill in the Gulf of Mexico, but there are still open questions about the extent of the damage the gusher caused. BP and the federal government are discussing a settlement, though the exact amount of money BP will have to pay up is still unclear.

But take, for example, some information that Greenpeace recently received in response to a Freedom of Information Act request filed more than two years ago seeking evidence of the spill’s impact on endangered species. The latest batch of photos and documents the group received focuses on a dead sperm whale that researchers on the ship Pisces found about 77 miles from the site of the Deepwater Horizon on June 2010. (The group had previously received a batch of photos of oiled sea turtles.)

The dead whale was documented in a press release on June 16, 2010, but the Greenpeace FOIA also turned up a number of photos of the bloated, burnt whale that appeared to have been floating in the water for at least a few days before it was found.


The photos are pretty grim; it’s hard to even tell it’s a whale until you notice the protruding jaw bone. It doesn’t appear that photos of it were widely circulated at the time, though at least one National Oceanic and Atmospheric Administration (NOAA) photo did appear online, and a school teacher aboard the research ship also posted some of her own photos of the body. Several of the emails released in the FOIA response state that people aboard the ship were told not to post photos. “I just spoke to the command center in Houma and they have asked that you all not post the photos to anyone as they are part of an official investigation,” says one email sent from a NOAA staffer to others on the ship, asking that they refrain from posting until they get permission from the Joint Information Center.

What’s unclear is whether they ever determined what killed the whale, which was described as “sub-adult.” It was already pretty decomposed when they found it. The press release noted that it was “impossible to confirm whether exposure to oil was the cause of death,” but said that they collected skin swabs, blubber, and skin samples for analysis.

But there weren’t any follow-up reports on what those tests found. The official tally of animals affected by the spill on the NOAA website says that there were two dead sperm whales found in the months after the spill; it’s unclear whether the whale in the photographs is included in that figure. [NOAA had not responded to questions by the time this went to press, but I have added an update below.)

Greenpeace wants to know what happened to the whale. “They never published them or made an explanation,” said Kert Davies, the group’s research director. “They took samples, swabs, but we never saw the lab results … What happened to it? How many times does a whale just die?”


Hal Whitehead, a biologist and sperm whale expert at Dalhousie University in Nova Scotia, told Mother Jones that most whales live a long time—as long as 80 years—and typically die of natural causes. The population of the endangered sperm whales was dense in the Gulf at last tally, but still relatively small—between 1,400 and 1,660. “They appeared to be doing well before the spill,” said Whitehead.

But the sperm whale population was still vulnerable, and there was a lot of fear at the time that even a few deaths could severely impact the their long-term survival. Biologists also note that only some of the dead bodies are actually found and tallied; there are likely more that are never found.

While this is a photo of just one dead whale, it does speak to the larger questions of just how much the Gulf spill cost—in dollars, but also in things that are hard to measure, like the loss of endangered species.

UPDATE: NOAA spokesman Ben Sherman said Wednesday morning that the agency did conduct tests on the whale samples, but “because the animal was so badly decomposed the cause of death could not be determined.” The whale was, however, included in the tally of bodies collected after the oil spill. He also said that in telling people on the boat not to publish photos, they were following the protocol for the federal response team on reporting new findings “so that the information could be cataloged and verified as part of the the investigation against BP.”

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
