The Wall Street Journal article “Arctic Site Is Oozing Methane” of Friday, March 5, refers to “the frozen seafloor of the East Siberian Arctic Shelf.” A Friday, Jan 2, 2009 Journal article “The Warming Earth Blows Hot, Cold and Chaotic” had a similar reference: “... formerly frozen seafloor... along the Siberian coast.”
Wouldn't the normal Wall Street Journal reader interpret 'seafloor' as that part of the Earth's surface (70%) under water? And since water becomes less dense when it freezes, the resulting ice floats to the top. A widely available reference [World Almanac] says “The Temperature inside the earth increases about 1° F with every 100 to 200 feet in depth, in the upper 100 km of earth....”
So how can any 'seafloor' ever be, or have been, 'frozen'?
Is this 'problem' another result, like 'global warming/climate change' of one of those IPCC/East Anglia U. overnite pajama party sleepovers?
I've lived in Detroit, St Louis, Kansas City, Pittsburgh PA, Marblehead MA. Worked as tech rep in Southern CA, Bay area, NYC, I've been to Europe a dozen times (Ireland, UK, Scotland, Sweden, Finland, Belgium.

For about a year I had small offices in Clayton MO, in the Country Club Plaza in KC. I rode a ten-speed bike around Lake Michigan (The bottom half in one week in June 1978, another week for the top half in 1980, used the Badger both times.
Don't get to travel much anymore, but still try to rent a car and go around the Lake in March every year. Sure, there's still snow, and it's not warm, OTOH there are no bugs and no toursts. Greatest little tavern in the world is Sherry's Port Bar in Garden UP MI
