Whale and dolphin deaths 50 times worse than admitted after Deepwater oil spill'Whale and dolphin death toll during Deepwater
disaster may have been greatly underestimated'
The Deepwater Horizon oil spill of 2010 devastated the Gulf of Mexico ecologically and
economically. However, a new study published in Conservation Letters reveals that the true impact of the disaster on wildlife may have been gravely
underestimated. The study argues that fatality figures based on the number of recovered animal carcasses will not give a true death toll, which may be
50 times higher than believed.
We all knew this tragedy was being downplayed from the start. From lying about the amount of crude oil spewing
into the ocean for months on end to lying about the effect it was having on the environment. To top it off they were using Corexit, an extremely
harmful chemical agent to clean up the oil..
It should not be a surprise to any of us that the death toll is actually much higher than we were lead to believe. That being said, this is still
absolutely atrocious.. The effect this has had on wildlife and people in surrounding coastal areas is disgusting.
Largest oil spill in US history
"The Deepwater oil spill was the largest in US history, however, the recorded impact on wildlife was relatively low, leading to suggestions that the
environmental damage of the disaster was actually modest," said lead author Dr Rob Williams from the University of British Columbia. "This is
because reports have implied that the number of carcasses recovered, 101, equals the number of animals killed by the spill."
The team focused their research on 14 species of cetacean, an order of mammals including whales and dolphins. While the number of recovered carcasses
has been assumed to equal the number of deaths, the team argues that marine conditions and the fact that many deaths will have occurred far from shore
mean recovered carcasses will only account for a small proportion of deaths.
Only 2% of deaths recorded every year
To illustrate their point, the team multiplied recent species abundance estimates by the species mortality rate. An annual carcass recovery rate was
then estimated by dividing the mean number of observed strandings each year by the estimate of annual mortality.
The team's analysis suggests that only 2% of cetacean carcasses were ever historically recovered after their deaths in this region, meaning
that the true death toll from the Deepwater Horizon disaster could be 50 times higher than the number of deaths currently estimated.
The data has obviously been mishandled and misconstrued intentionally
to mislead people! It is so obvious and I can't say I didn't expect this,
mega corporate entity like BP would act in the same kind of way. Devious, manipulative and deceitful in order to minimize public chastising
Carcass count highly misleading
"This figure illustrates that carcass counts are hugely misleading, if used to measure the disaster's death toll," said co-author Scott Kraus of the
New England Aquarium "No study on carcass recovery from strandings has ever recovered anything close to 100% of the deaths occurring in any cetacean
population. The highest rate we found was only 6.2%, which implied 16 deaths for every carcass recovered."
Now obviously we cannot expect them to be able to recover all the carcases.. but that is not the point. The fact of the matter is, they knew
the amount of carcases they recovered was nowhere near the real number.. and yet they parade the data as if it is the full extent of their damage. It
is truly disgusting and it angers me a lot.
