Sure it can. The p-38 was under 260 ft, in 50 years. That's 50 feet per year accumulation. The lake is under 13,000 feet of ice and is 20 million years old- however, with that thick of an ice sheet the basal ice is compressed immensely. So, each year's accumulation can be compressed to an inch. Also, the lake is 20Ma. But how old is the ice directly above it? As the article says, Antarctica was significantly more northward for awhile. And, the atmosphere was significantly warmer than today, pushing the ice limit closer to the poles. I don't have empirical data on all this, but I'll buy it.
Do I agree with drilling the lake? Eh, I dunno. Part of me says yes- potential for cool creatures is really high. But another part of me says no- that continent is the only one we haven't significantly, directly messed with.
Has anyone here been to Antarctica? Just curious. Kyle
