Quantifying, and Dealing With, the Deepwater Spill
Gooseygoose writes with a link to this analysis by Boston University professor Cutler Cleveland. "Some reports in the media attempt to downplay the significance of the release of oil from the Deepwater Horizon accident by arguing that natural oil seeps release large volumes of oil to the ocean, so why worry? Let's look at the numbers." Read on for a few more stories on the topic of the Deepwater Horizon spill.
theodp writes with some information on the remote-controlled efforts to stanch the oil's flow: "The work Tito Collasius does sounds a little like science fiction: Men on ships flicking joysticks that control robots the size of trucks as they rove miles beneath the sea in near-freezing depths no man could hope to reach. But BP's spill efforts rest in the hands of underwater remote-operated vehicle (ROV) pilots, who 'fly' the ROVs from command centers aboard ships, joysticks in hand and large banks of screens in front of them offering a view of the challenges they confront in the waters below. ROVs are typically used for commercial (as in the oil industry), oceanographic (science research and exploration), and military (mine reconnaissance and recovery) missions. If you're interested in joining Tito, training's available."
Even if BP were to effect a perfect block for the oil, though, there's still quite a bit of it swirling in the Gulf — you've probably seen some gut-wrenching pictures of the affected wildlife. Reader grrlscientist writes "Some people claim that we should euthanize all oiled birds immediately upon recovering them. But I argue it is our ethical responsibility to protect, clean, and save these birds, even after they've been oiled, just as we should preserve and clean their habitats."
Seems like there's far more oil than can be accounted for by dead organisms alone.
The total global biomass has been estimated to be 2000 billion tonnes with 1600 billion of those tonnes in forests.[13][14]
Net primary production is the rate at which biomass is generated in a given area, mainly due to photosynthesis. Some global producers of biomass in order of productivity rates are
* swamps and marshes: 2,500 g/m/yr of biomass[15]
* tropical rain forests: 2,000 g/m/yr of biomass[16]
* algal beds and reefs: 2000 g/m/yr of biomass[15]
* river estuaries: 1,800 g/m/yr of biomass[15]
* temperate forests: 1,250 g/m/yr of biomass[15]
* cultivated lands: 650 g/m/yr of biomass[15][17]
* deserts: 3 g/m/yr of biomass[17]
* open ocean: 125 g/m/yr of biomass[15][17]
* tundras: 140 g/m/yr[15][17]
(Multiply by millions of years...)
You can't take the sky from me...
While Palin's pretty shamelessly rent-seeking (drill in Alaska? why, how convenient!) the idea that we've been avoiding one ecologically sensitive area (pristine Alaska wilderness) in favor of drilling in another, potentially more sensitive area which is also much much riskier to drill in (the Gulf) for whatever reason (perhaps it's easier for people to conceive of the former as wilderness-y?)... that part of her idea is not without merit. Regardless of our ultimate course of action, we should be sure that we are weighing the potential environmental impact a bit more dispassionately, and with an eye to overall impact - including the impact of the risks, so elusive and difficult to grasp until disaster strikes.
