Weather High 15, Low 9

Saturday Routine Data from the three main Poker Flat ponds (MST & two Secondary) are collected on Saturdays. All three are within the research range, safe from snow machines (snowmobiles) and pedestrians. A transect is an imaginary line marked with stakes posted at intervals of 5 or 10 meters. Snow samples, snow depth, snow temperature, and ice thickness are measured at each marker.

1. Stakes posted every 5 meters in this transect. Drilling occasionally causes minor floods. (see slushy trail in front of Martin)

2. Hotwire gauge is a less destructive instrument used to measure ice thickness. More information on hotwire gauges will be provided soon.
