The World Where Oil Flows Free

Bubbling crude, La Brea by antgirl The Gulf Oil Spill has been the event at the top of everyone’s mind for many weeks now, almost to the point of our adapting to the initially shocking concept. The images that have surfaced have been heartrending enough, though, that the shock factor hasn’t been allowed to completely fade. Predictions of the results to come in the next weeks and months are concerning to say the least, and the estimate of how much has been leaking each day continues to rise. BP comes up with a new method to “fix” the problem every few weeks, each seeming promising with a side-serving of bad news.  Effects on humans are starting to surface, some gruesome news and some simply tragic projections. With all of this on our plates, it’s understandably hard to think about, let alone discuss, other similar issues.

One more brick was added to the weight of environmental concern when, on June 11th, another oil spill was reported, this time in Utah. How could an oil spill happen in the middle of the continent? This time it wasn’t an oil rig that failed; in the mountains south of the Great Salt Lake, an oil-transporting pipeline was breached around 10pm. Residents who reported a strong petroleum scent around 7am the next day allowed for the leak to be stopped less than 24 hours after it began. Regardless of the speed with which it was stopped, 33,000 gallons of crude oil were leaked into Salt Lake City creeks and a pond- but not the Lake. Because of the national disappointment with and disdain for the oil giant BP, Chevron responded quickly and aggressively with cleanup devotions.

This leak was obviously a dramatically smaller scale than the spill in the Gulf of Mexico. Instead of a pipeline tapped directly  into natural oil stores being busted, a quarter-sized hole was melted in the controllable pipe transporting oil in UT, and it was all over in 24 hours.

The BP underwater pipe has been gushing tens of thousands of gallons each day, for two and a half months. In the UT spill, around 300 Canada Geese and ducks were covered in oil, and fewer than 10 were killed; one endangered fish species was threatened by the spill. The Gulf of Mexico’s biota are threatened in a much, much broader sense- as you might imagine, considering the unimaginable quantity of poison being spewed into the ocean.

While much of the oil spilled in Utah has been cleaned up, the efforts in the Gulf of Mexico have comparatively only just begun. The estimated clean-up time is months, possibly years; the truth is that the effected coastlines (their ecosystems, their businesses, their citizens), especially those closer to the epicenter, may never recover.

While the Gulf oil spill eclipses other fossil fuel issues in the eye of society at present, it also brings an important topic right to the surface of the pile of important current issues, and in some cases inspires reflection.

Would we still be discussing the Utah oil spill, were the BP tragedy not over-shadowing its significance?

The answer is “Maybe not;” spills are not uncommon, mishaps at drilling sites are not uncommon. What makes the BP spill different is the enormous individual scale, proximity to affluent nations, and resulting publicity.

We do not often hear about the ill effects of the oil industry that are happening in less-fortunate regions of our world.

If we ignore the intense sociological disasters surrounding the oil industry in the Niger Delta region of Nigeria, there are statistics to look at that might make the president of BP’s hair curl. It’s estimated that from what are technically Shell and Chevron operations, there are three hundred small and large oil spills in this area each year, due to various factors including oil piracy, aging equipment, and worse-than-poor regulation. In this undeveloped region where locals see no benefit from the industry, oil spills surround the villages. An image of the ruined environment was painted potently by one BBC article;

“Visitors to the Nigerian village of Kpor, deep in the Niger Delta, are greeted by strange sights: silver frogs blink from gleaming puddles, sunlight bounces from an eerie black lake, and dragonflies hover over cauldrons of tar.”

This is a generally unillustrated tragedy, an example of what we are not seeing through the corporate veil. Information is not exposed for many reasons- too many to discuss here- but these events are significant enough to spend time digging for.

Discussed above are only the results of our addiction to oil. What about the other common fossil fuels that we depend on? If we disregard the carbon emissions and their effects, related to burning any fossil fuels-

  • Coal mining means mountain tops destroyed, geology and topography both obliterated as removed mountain tops are filled into valleys; this is not to mention the pollution nightmares that come along with mining, or the health risks: 11,000+ injured (lowest number ever recorded), 69 killed most recently.
  • Natural gas mining–hydraulic fracturing/fracking— creates air-polluting ground-level ozone, poisons the surrounding groundwater and has severe effects on surrounding communities.

Maintenance of our presently strong socioeconomic bonds to fossil fuels are already fatal, both to operators and the surrounding environment. What will it be like when these limited resources begin to truly dwindle, when, if we haven’t changed the juice our society runs on, we are mining every potentially coal-filled mountain and drilling into every oil deposit the earth’s crust has left to offer? We can be assured worker safety and environmental health will not be more of a priority then, in the hour of desperation, than it is now.

It seems that now is time to start using the information we have already to start making changes in the way our energy system works.This is not to say that there won’t be risks associated with other energy practices, but after looking at the information surrounding the above-mentioned options, I would argue that finding an environmentally-friendly energy option that posed the same level of human and environmental health risks would be difficult. Environmental safety is an inherent property of an environmentally-friendly product, afterall.

Gulf of Mexico Oil Spill Leaks On

http://www.flickr.com/photos/uscgd8/4542937668/ On April 20th, 2010, in the open ocean 42 miles southeast of Venice, Louisiana, a 560-million-dollar deep-water oil rig licensed to BP, experienced an explosion. Eleven workers were killed and 17 were injured in the explosion, with the other 98 on board exiting safely unharmed. After the initial explosion, the rig burned and two days later sank to the bottom of the ocean.

A few days after this shocking event made headlines, the resulting oil spill became apparent. Oil from the rig’s well immediately began to spew forth into the water column through a damaged well-head, forming a 5-mile long oil slick on the ocean’s surface in short time. Within two weeks, BP had tried and failed to use the well’s blowout protection, President Obama declared dedication of any and all available US resources to the purpose of resolving  the spread of this spill, BP stated that it would take all financial responsibility for legitimate claims and the cleanup of the spill, and began the two-month project of drilling a relief well.

In the following month, a fishing ban was extended to 19% of the Gulf of Mexico’s waters, all new drilling projects in the area were suspended, and several different remedial attempts were made, some simply failing and others actually increasing the oil’s flux into the ocean. The rate of the spill that began 51 days ago has not yet been determined, due to several factors including communication barriers between BP and external scientists, but the official government estimate is between 12 and 19 thousand barrels per day.

Although it was once thought that the spill could be contained offshore, the oil leaking into the Gulf of Mexico has now reached over 120 miles of coastline. Tar balls are washing up on shore, animals are being covered in oil with a plethora of horrifying effects. It is not clear what the effect of the toxic oil dispersants being used will be on the delicate marine and coastal wildlife. Though it sounds extreme, it has been discussed that there is serious potential for this oil spill to be considered ecocide, or to reach that level in the coming months or years. I won’t link you to the videos of oil-covered struggling or already-deceased wildlife—seek them out at your own risk (of heartbreak).

As these negative events continue to affect the shorelines, locals are concerned. The fishing ban is necessary, but is just a concrete representation of the loss of money on the part of the fishing industry. The coasts are soaked in oil, animals are dying, and the tourism business is not looking good, either. “My concern is after everything is cleaned up, if they can clean it all up, and they leave, what is our business going to be like?” said Dudley Gaspard, owner of the Sand Dollar Marina and Hotel on hard-hit Grand Isle, Louisiana. While all of these local businesses are concerned, so are the oil drilling workers who operate in the Gulf. The six-month moratorium on deepwater drilling that has been imposed has the potential to eliminate as many as 20,000 jobs, according to some; the ban on shallow water drilling has been lifted. BP’s stock value has dropped dramatically, as would be expected during a crisis such as this.

On June 4th, a partially successful capturing system was put into place. BP has lowered a cap over the leaking well, sucking some of the leaking oil up through a mile-long pipe it is connected through. There are vents in the dome-shaped cap that allow some oil to escape, and oil is also billowing out from below the hood. While this is not a large step forward, it is a step: some oil is being captured. BP’s most recent estimates suggest they were able to capture 10,500 barrels of oil in 24 hours using this method, and they expect they will soon be able to use an additional containment system to increase this control. They have even made preparations for the event of a hurricane.

Here is a video of the underwater spill in action:

There is some murmur that this oil spill may be the push that the U.S. needs to secure clean energy and energy efficiency legislation. Thus far, concrete statements have only been made about the wish to change legislation revolving around oil drilling. House of Representatives Speaker Nancy Pelosi, after meeting with several committee heads, told reporters a wide range of legislation was being considered, including oil leasing reform, liability reform, ensuring worker safety and the “integrity of the certification process” when oil companies want to start a new offshore drilling project.

In more local news, your orders of fried clams this summer might get a little expensive. Researchers have warned that New England may experience major red tide events this year.

Lastly, a potentially positive piece: California is considering “un-grand-fathering” power plants permits to dump waste heat into coastal waters.

Oceanic hydro-power digest

wave crash by silverxraven Oregon is set to test another buoy-based power generation system after the previous system sank two years ago.

Closer to home, plans to deploy a more traditional turbine-based system known as SeaGen in the Bay of Fundy were announced last year. An earlier Irish SeaGen installation has been operational for more than 1,000 hours since it was installed in 2008.

Both systems use “run-of-the-river” technologies which should minimize disruption of the surroundings, unlike the Annapolis basin installation also in the Bay of Fundy which operates more like a conventional hydroelectric dam.

Also of note, a relatively recent announcement about more cheap renewable energy in the future from north of the border into “Boston” which seems to have received little attention.

Earth’s “New” Ocean

A new ocean is emerging on planet Earth. This ocean was once composed mainly of solid ice, sometimes hundreds of meters thick. During this past summer however, the first known commercial shipment from Asia to Europe took place — via the Arctic (NYTimes). The German cargo vessles Beluga Foresight and Beluga Fraternity are two examples of such a new-found commercial shipping trend. The cargo carriers originally left from South Korea and are departing on their last leg from Siberia.  Such a passage has been the dream of many a mariner, sea-voyager and commerical tradesman, yet the gripping reality of vast open Arctic waters is not the dream of those concerned about climate change. For about a month each summer, Arctic ice recedes to a degree that now allows cargo ships to pass through with ease, unlike in years before where large ice-breaking machinery had to be used. Scientists are concerned that this trend will lead to an economic thirst for greater speed in commerce thus fueling the world’s appetite for rapid growth and development. While growth and development aren’t necessarily evil entities unto themselves, the quantity of demand as developing nations develop and as global population soars is what puts the planet, and the long-term health of the species living on it, in serious jeopardy.

Applied Chemistry

Beakers by Move The Clouds

This month’s Sierra magazine includes a blurb about some of the lesser known impacts of fossil fuel use & global warming.

Half of the carbon dioxide we’ve put into the atmosphere since 1800 has been absorbed by the world’s oceans, increasing acidity by 30% and changing seawater to carbonic acid. In terms of pH (lower numbers equate to higher acidity), that means a drop of 0.1 from preindustrial levels [8.1] to today’s 8. If trends continue, ocean pH will be 7.7 by the end of the century. At 7.8, however, shell formation ceases. Barnacles, sea snails, and corals will decline precipitously.

In fact, the Caribbean is already impacted, as are sensitive Alaskan waters.

For those of you whom may have forgotten your high school chemistry: Like the Richter scale, pH is logarithmic and each whole number actually corresponds to a ten-fold change in the measured value. Thus the drop from a pH of 8.1 to 8 amounts to the cited 30% increase in acidity, or more specifically a 26% decline in alkalinity.

Carbonic acid is the product of carbon dioxide dissolved in water and it is present in beverages from seltzer to soda pop. Although it is a very mild acid, large quantities of can take their toll, and carbonic acid’s presence in ground water is responsible for the formation of limestone caves. Limestone is of course a sedimentary rock formed from the skeletons and shells of ancient sea-life…

It is interesting to note that since 1976 the EPA has regulated alteration of of pH as a pollutant, permitting variance of 0.2 from normal. This standard has undergone some scrutiny recently, and is likely too lax.

Ocean temperature breaks June heat record & other canaries in the coal mine…

Ocean ThermographWhile climate change skeptics continue to derail needed climate policy and deepen the public’s confusion on accepted science, the planet is exhibiting more acute global warming symptoms.  Recent observations are indicating that climate change is occurring at a faster pace and of a greater magnitude than  predicted by IPCC models.  Our Oceans are showing a decreased ability to absorb our excess carbon, leading to ocean acidification– reducing the ability of many marine organisms to build their shells and skeletal structure.

The Ocean which covers 70 percent of our planet, just broke a record last month for the warmest temperature on record and combined with land temperatures it was second to 2005’s all time high.  Run away global warming is a real concern with the potential for accelerated ice melt and rising sea levels, which are also exceeding IPCC predictions in the Latest Climate Science publication.

Summer has yet to run its course and it is likely that other potential record breaking climate change news will occur.  How much more data is needed before we can leave the debate behind and step up our collective action on climate change?  In a recent Global poll, Americans ranked government action on climate change as the lowest priority compared to any other country. We have a long way to go…
