First, briefly, the administrative information. The National Science Board (NSB) is the body which governs the National Science Foundation (NSF). Board meetings are held roughly quarterly...the schedule, agenda, summary report, and open session minutes, are published here. Additionally, the open portion of the meetings are videoconferenced live, and archived.
One of the significant discussion points at the July meeting was the status of obtaining an icebreaker to support the 2011-12 resupply...an agenda item listed on the public agenda as "McMurdo Station Resupply Issues." I have watched the video several times, the archived webcast was still available in October 2012 but is no longer. Go to the conference summary link for more detailed information. The meegint video included an explanation by Karl Erb, the director of the Office of Polar Programs, along with Brian Stone and George Blaisdell. More information than you probably cared to know...including discussions about what happens if we DON'T get an icebreaker...as well as NSF Arctic science...the status of the Antarctic support contract award...the fact that more than 300 tourists are expected to be at Pole on 14 December, the centenary of Amundsen's arrival...
After outlining the fact that the US Coast Guard polar class icebreakers aren't available, and neither is the Oden (because of complaints in previous years that it was doing science in the Antarctic when heavy ice disrupted Swedish ports)...the three options were discussed:
Other less likely options, perhaps viable in future seasons, were also discussed...a Canadian icebreaker, the Australian science icebreaker/supply vessel...or even a hovercraft to transfer fuel to McMurdo from a tanker on the ice edge. And the options for a curtailed season were described as well...including the statement that the decision to curtail the season needed to be made in mid-August, and that once that decision had been made, it would be difficult to reverse.
[Note...the above information has been overtaken by events...in late August 2011 NSF announced they had signed an agreement with a Russian company to charter a diesel icebreaker for the 2011-12 season.]
