A new study published last month reveals how the 2010 BP Deepwater Horizon oil disaster likely caused life-threatening heart deformities and irregular function in the fish embryos of yellowfin tuna, bluefin tuna, amberjack and swordfish.
If you’re thinking that this sounds like another study we reported on last month, then you’re right. A number of different studies have been conducted on fish hearts, and each of them is an important piece of the puzzle that scientists are assembling to understand the impacts of the BP Deepwater Horizon oil disaster.
This latest study conducted by Dr. John Incardona and others clarifies how the oil from the BP oil disaster affects the embryos of large predatory fish living in the open ocean (or pelagic zone) of the Gulf of Mexico. Previous studies have determined that crude oil can be toxic or have delayed fatal effects on fish living in cold Arctic waters, such as pink salmon, or in warm freshwaters, such as zebrafish. We’ve also recently learned that Gulf killifish living in oiled areas of coastal Louisiana are suffering from deformed hearts and reduced chances of survival; another study helped us better understood the mechanism by which crude oil affects tuna hearts. Collectively, this research allowed scientists to make assumptions about how oil might affect fish living in the warm offshore waters of the Gulf.
Earlier, I wrote about coastal and marine spatial planning and the tools necessary to effectively implement it. Today though, I wanted to discuss the regions and industries that are already putting these ideas to good use.
At the state level, Washington, Massachusetts, Oregon and Rhode Island have already created comprehensive ocean plans, and several other states—such as New York and several states along the Gulf of Mexico—are starting to do the same thing. This is a great start, but the ocean does not obey state lines. As a result, regional partnerships are essential in facilitating coordination between federal, state, tribal and local entities.
Whales are mysterious creatures, as the scene that unfolded in the Everglades last week has taught us. Over 50 pilot whales stranded themselves in a remote part of Everglades National Park, and scientists are still unsure what caused this to happen. Strandings are not uncommon, because whales are very social animals, and they are known to gather around a sick member of their pod.
This pod of short-finned pilot whales traveled into just three feet of water – a far cry from the deep Gulf of Mexico where they are common – and responding to this emergency fell to a few knowledgeable groups. A group of 31 first-responders spent days helping the whales to navigate unfamiliar shallows for a 20-mile return journey to more suitable waters. In the end, the pod was last seen swimming back out to sea, but 22 of their members died in the Everglades.
The people of the Gulf are still suffering from this tragedy.
Three years ago, I found myself at a late-night community meeting on the coast in Alabama to discuss the oil disaster. At that point, oil was still spewing uncontrolled from the wellhead and huge portions of the Gulf were closed to fishing—meaning that thousands of people were out of a job and countless more were unable to enjoy doing the things they’d always taken for granted, like fishing, boating and swimming in the Gulf.
About an hour in, a broad-shouldered, weathered man stood up to discuss what this disaster meant for him. He explained that he made his living as a fisherman and now couldn’t afford to feed his family. As he talked, his voice began to break, and he struggled to keep talking through the tears. It was then that I knew this disaster was deeper than the sheen on the water; it was in the hearts of each Gulf resident.
Yesterday I wrote about Hurricane Isaac’s impacts to our coastal environment as well as the unfortunate reminder that an unknown quantity of BP oil still lingers in the Gulf, needing only time and the right conditions to once again wreak havoc on our beaches, marshes and coastal communities.
Events like hurricanes serve as sobering reminders of how critical coastal restoration initiatives are to the long-term sustainability of our Gulf communities, our economies and, of course, our natural resources. But as critical as restoration of our coastal resources are, they are only part of a larger picture of ecosystem restoration in the region. Restoration of our marine resources are equally important to preserving our coastal way of life.
Ocean Conservancy views restoration of the Gulf ecosystem as a three-legged stool. Each leg depends on the other for balance and function. If you lose one leg, you no longer have a strong base, and you will almost certainly topple. The three legs of restoration in the Gulf are: restoration of the coastal environment, the marine environment and coastal communities.
We must focus our effort, energy and funding resources to all three of these vital areas if we are going to realize our vision of a vibrant and healthy Gulf region. Is it a lot of work? Yes. Are there competing needs for limited funds? Yes? Do we have to find a way to do all three? Absolutely. Continue reading »

I wrote a blog post about the start of hurricane season back in June, and I am writing this one today in Hurricane Isaac’s sights. Hurricanes are anything but predictable, and this one in particular has been hard to track. Would it rain and blow into the Republican Convention in Tampa? Head West towards Texas? Now, less than 24 hours away from landfall, it looks like Isaac has made up his mind to aim for somewhere in Louisiana or Mississippi, which means rain and wind anywhere across the Gulf Coast, and hopefully not much more than that. We hope.
If you are watching the approach of the storm on TV, you’d think that hurricanes are some sort of spectator sport or reality TV show. DEVASTATION! MANDATORY EVACUATION! DESTRUCTION! It turns what is a serious event into a sort of comic theater. Note to newscasters: Gulfport is in MS and Mobile Bay in in AL. Just sayin’. (Sorry, I’ve been seeing silly screen shots on Facebook all morning that are geographically confused).
In the midst of the TV hullabaloo, I thought I’d take a few minutes to tell you what I think about Hurricane Isaac while safely tucked away from the weather, listening to the weather radio and wondering what the day will bring. Mind you, these thoughts are mine alone, and not meant to represent those of Gulf residents, generally. Continue reading »
