No, this isn’t a post from last year. Oil from the Macondo Well site is fouling the Gulf anew – and BP is scrambling to contain both the crude and the PR nightmare that waits in the wings. Reliable sources tell us that BP has hired 40 boats from Venice to Grand Isle to lay boom around the Deepwater Horizon site – located just 50 miles off the Louisiana coast. The fleet rushed to the scene late last week and worked through the weekend to contain what was becoming a massive slick at the site of the Macondo wellhead, which was officially “killed” back in September 2010.

News reports of the failed attempt to contain the oil-spewing equipment on the bottom of the Gulf of Mexico have referred obliquely to things like "ice crystals" or an "icy slush" clogging the hardware that was intended to cap the leak. Anyone who is paying attention would recognize that there's a bit of a problem here, in that, even at the temperatures and pressures of the ocean at the site, the water there is very much in its liquid phase, as are the hydrocarbons that are spewing through the leak. The methane that caused the original explosion remains gaseous down to -161°C. The "ice" that's forming is actually a solidified mixture of methane and water called a clathrate. Clathrates have also been in the news because of a potential role in climate change, so it seems like an opportune time to explain what they are.
Methane is considered to be a more potent greenhouse gas than carbon dioxide. It only stays in the atmosphere for a few years on average, but the majority is removed by oxidation, which converts it into carbon dioxide. So there's a chance that clathrates could accelerate and/or enhance any climate change induced by high levels of atmospheric carbon dioxide.
Clathrates are composites in which a lattice of one substance forms a cage around another. Methane clathrates (in which water molecules are the cage) form on continental shelves. These clathrates are likely to break up rapidly and release the methane if the temperature rises quickly or the pressure on them drops quickly—for example in response to sudden global warming or a sudden drop in sea level or even earthquakes. Methane is a much more powerful greenhouse gas than carbon dioxide, so a methane eruption ("clathrate gun") could cause rapid global warming or make it much more severe if the eruption was itself caused by global warming. The most likely signature of such a methane eruption would be a sudden decrease in the ratio of carbon-13 to carbon-12 in sediments, since methane clathrates are low in carbon-13; but the change would have to be very large, as other events can also reduce the percentage of carbon-13. It has been suggested that "clathrate gun" methane eruptions were involved in the end-Permian extinction ("the Great Dying") and in the Paleocene–Eocene Thermal Maximum, which was associated with one of the smaller mass extinctions.

I've been keeping an eye on this ever since it started.
