Current temperature: -15C
Food: Another hot lunch AND dinner! Lunch was actually “breakfast”: baked French toast, steel-cut oats, real maple syrup, Canadian bacon and fruit salad (kiwi, grapefruit, orange, apple, pineapple). Yum! Dinner was Sriracha and wasabi glazed halibut, Basmati brown rice, dal, fresh salad with raspberry chocolate cake for dessert!
Today was a bit long … starting at 0800 (morning meeting) and returning to camp at 2300. We did quite a bit … in a manner of speaking. We cleaned up our “mess” (storage of sample bottles in the Greenhouse) and began, in earnest, my melt experiment. Bob helped wire the data logger and I, well … I soldered a whole bunch of wires! We have thermocouples running down two bamboo poles, and tomorrow we will see what (if anything) happens when melt occurs at the surface. In addition to monitoring temperature, we’ll dig snowpits to evaluate physical stratigraphy, density and we’ll sample for snow chemistry. Fingers crossed.
We also helped set up the drill that we used at “North Drill Camp” in Summit Camp today. They are conducting an experiment (“firn-air cooling”) to keep frozen foods frozen based on calculations of snow-air permeability and thermal conductivity. Basically, they are drilling a 10-meter hole to “suck” air from the firn to keep an above-ground food-storage structure at the USDA-approved temperature of -18C. Right now, Summit Camp keeps its frozen food in an underground “freezer trench”, but that has to be moved and redone every couple of years.
Tonight, after dinner, we went out to borehole log the site we just drilled. Bob uses a novel technique to optically record stratigraphy in a borehole. While he logged the North Drill Camp borehole, Zoe and I attached the thermocouple setup to the data logger, and the three of us set up an experiment site just northwest of the borehole.
I can’t believe its 12.30am! All I know is, out there at North Drill Camp, its business … its business time! [that’s why they call them ‘business socks’] Cheers!
