Last year, on this date, I noted that the DWH spill was still very much in everyones minds and hearts through retrospective media reports, images and personal stories. Now that we are at two years after the start of the incident, media (and public) interest once again has peaked about the spill, but for more troubling reasons from an environmental perspective.
Reports have begun to surface related to potential impacts on the flora and fauna of the Gulf of Mexico – impacts that scientists are attempting to carefully determine whether they may be associated with the more than 200 million gallons of crude oil and the more than 1.8 million gallons of chemical dispersant applied. These (with appropriate links) include:
- Unexplained lesions in finfish;
- Extensive damage to corals;
- Malformed invertebrates, including shrimp; and
- A continued Unusual Mortality Event in dolphins, including findings of brucellosis and animals in “severe ill health”, among other stories.
However, there is some good news on this front. Scientists, with sizable funding support, are attacking these questions with a voracity that is rarely seen with environmental issues, attempting to ascertain the root causes of these (and other) problems. While it is easy to point the finger and blame the spill outright for such impacts, without using sound scientific principles, the ultimate outcomes can become muddled due to little baseline (pre-spill) information, the possibility of several “smoking guns” causing sick animals, and other confounding issues. With the skills of the folks working these problems, I have little doubt that we will get better results than is often seen after other disasters.
You may say “who cares?” a bit to all this science-speak; the environment is still messed up. And shouldn’t we concentrate on other more important issues, such as increasing prevention and better understanding how to care for oiled animals in the future? Well, I would say: why not do all three? In addition to the Natural Resource Damage Assessment projects going on, we have basic science occuring, with organizations such as the Gulf of Mexico Research Initiative allocating hundreds of millions of dollars to better understand the impacts of oil and dispersant on the GoM ecosystem. We also have significant efforts occurring at the Federal level to minimize the risks of incidents such as the DWH occurring in the future, with new innovations on blowout prevention and control coming forward and a newly-aligned MMS focusing on the risks.
On the oiled wildlife front, most oiled wildlife response organizations I know of have taken the time to evaluate their own processes and methods to see how they can do things better. Just this past week, Emily gave a webinar on changes to the OWCN protocols for animal care, and a fully revised version of both the oiled bird as well as mammal protocols, are on the horizon. On the international front, a newly-energized effort has been taking place trying to better develop a method to provide worldwide oiled wildlife response capabilities through a organized collaboration of key organizations. In all, these are exciting times!
This is not to say we should become complacent. The best clean-up effort, after all, is prevention of oiling of our wildlife in the first place. Both Nationally as well as Internationally, we have a long way to go to be able to be comfortable with our plans and systems. On the oiled wildlife side, while we have come a long way in the past decades, we always have things to learn and plans to develop and test to ensure rapid, efficient and effective collection and care, should animals become affected.
In closing, I would like to conclude this blog/discussion/soapbox asking you to join me in remembering the 11 crewmembers of the Deepwater Horizon rig who perished on this day. I wish everyone a safe and healthy April 20th.
