Maybe the Post-Gazette has this story somewhere buried below Rich Lord's excellent series on the local "Network", which itself is being buried below Steeler mania. But Yahoo only listed the Tribune Review for this story (the author is "Wire Reports"). I also saw it on Treehugger dot com.
So instead of floating on the top of the water as Lisa Margonelli tells us it should (June 2010) , there is a bunch of oil on the sea floor in the gulf, covering lord knows how much area (zero miles from the Deepwater Horizan well, 80 miles from the well, yada yada). Of course, the Wire Reports story the Trib chose includes lots of doubting experts. But personally I blame those kooky dispersants that BP (and the stupid government) said was evaporating the oil (as if airborne oil is somehow better). One thing I do know is that I am not going to be eating any shrimp for the next few years (or any warm water fish).
