...Harvard men’s ice hockey team has been used to skating as the underdog for most of its current four-game unbeaten streak...
What Barber's expedition further discovered was that some Arctic sea ice is not only whisper thin, but that even in places with thick ice, the ice was not as solid as satellites had indicated. That thick ice was still there, but largely as individual chunks covered with a veneer of new ice that masked their true nature. "It's significant and it's surprising," says Maslanik. "I wouldn't have expected that the ice would be as rotten and weak as what David Barber's team found...
This suggests that the analysis of satellite observations might be due for updating. "The algorithms we use to monitor ice extent were developed a long time ago," says Stroeve, "based on what 'typical' ice looked like at that time. We know there are errors with the measurements." The weakness in multiyear ice also suggests that if the unfavorable winds and currents that caused the 2007 meltback should recur, the Arctic Ocean could undergo another especially dramatic summer melt. Not just the first-year ice might go, but also some of the "rotten" multiyear ice that Barber encountered...
That in turn would trigger one of the many positive feedback mechanisms that could speed up the warming effects of greenhouse gases. Open ocean reflects less of the Sun's energy than ice does, so a large-scale summer melt would mean more absorption of heat in the ocean. The warmer ocean would heat the air above it, which would slow the refreezing of ice in winter, which would in turn become even more susceptible to melting in summer...
Over the past five games, in which Harvard has taken down No. 5 Yale and No. 13 Union, improved performance has come on both ends of the ice. Offensively, the Crimson has notched at least three goals in its past five ECAC games. Defensively, the improvement is even more pronounced. Harvard has given up 1.6 goals per game in its last five ECAC contests compared to 3.9 goals per game for the rest of the ECAC season...
