Congrats to Crow Emily, best Physical Science Paper at Western Research Forum! #westernu
Total 3 Crows waxed eloquent at the Western Research Forum. They all gave great talks, I enjoyed them. We just found out that Emily’s talk won best Physical Science paper! Her plaque says:
2011 Western Research Forum
The Society of Graduate Students
is pleased to award Emily McCullough
First Place in the Physical Sciences Oral Category

Didn't know this, NASA's Plutonium-238 situation "Cry Foul Finding And Funding Fuel" (via Satnews Publishers)
Well there you go, I didn't realize that (a) the US didn't make its own plutonium for the thermoelectric generators for spacecraft and (b) they USED to buy it from Russia but there is no deal in place now and (c) Congress won't pony up for US production. This shortage is starting to affect approved and planed missions. Yet another thing I like about doing ground-based science.

@globejunius: Saving Canada’s Arctic atmospheric lab - The Globe and Mail
On Sunday, for the first time in four months, the sun rose over Eureka on Ellesmere Island, 10 degrees from the North Pole. The sun's return brings rays that break up ozone, and the Arctic climate and atmosphere are changing every year.
But we are about to lose our main source of knowledge about these intricate, and life-altering, processes, because our northernmost environmental research laboratory, known as PEARL, is in jeopardy. If Canada is serious about scientific discovery, and its status as an Arctic nation, the lab must be saved.

No one questions the lab's merit. Its instruments have collected Arctic surface and atmospheric data used by the world's major research organizations, including the Intergovernmental Panel on Climate Change and the World Meteorological Office. The lab houses Canada's northernmost high-speed Internet connection, allowing for rapid dissemination of results. Research done at the lab has already found, for instance, that water evaporation in the Arctic is far more complicated than had been thought. The lab is the only one of its kind in the high Arctic, and has produced 37 refereed publications and trained over 50 young scientists in 10 years.
PEARL is in trouble because one of its main sources of funding, the Canadian Foundation for Climate and Atmospheric Sciences, has lost federal support and is slated to wind down this year. A few of its instruments could, in theory, be moved, but our scientific heritage would be lost. As with the demise of the long-form census, data will no longer be comparable over long time-periods, making the data already collected less valuable.
Atmospheric research is important for all of Canada, but northerners are particularly vulnerable. “It's in the Canadian High Arctic where the global warming process is proceeding most rapidly,” says Richard Peltier, professor of physics at the University of Toronto. In addition, pollution from the south (and from the North itself, as it industrializes) leads to ozone loss and threatens the North's more fragile ecosystems and populations.
“How else would we expect to learn about the Arctic, if we don't do it ourselves?” asks James Drummond, professor of physics at Dalhousie University and principal investigator at PEARL. It's a challenge that puts the question of Canadian sovereignty in high relief, and deserves a response from our elected officials.
Thanks to the Globe and Mail for helping to inform Canadians of our government’s choice to abandon Canada’s northern-most lab for studying the atmosphere from the surface to the edge of space. The doomsday clock is almost at midnight, but we are hoping the lab and the important time series of atmospheric measurements we have obtained can be saved.

Some terrific auroral pictures by Øystein Lunde Ingvaldsen in National Geographic.
Terrific auroral pictures, see the full National Geographic story http://bit.ly/gxxCk8 for more pictures and information. I spend many years in Alaska observing aurora and took a few shots in my time, but these photos have both beautiful detail and great color in the red lower borders.

Emily went for a walk
This wouldn't be noteworthy, except that it's my last walk in the sunshine for a few weeks, and it was a giant four-hour walk in frigid temperatures all the way around Frame Lake in Yellowknife. I (and my camera) are currently thawing out. Also, I heard a raven warble and sing today, and whistle, and he snapped his beak a lot - I hadn't realized before that they don't only "Caw!" (although, as usual, it turns out that Wikipedia could have told me that in advance). It was neat, anyways.
Northern Lights in Yellowknife
A timely text message from my Dad woke me up in time to see the sky lit up with aurora yesterday evening.
