The Science Behind Water Depth
On Aurora pond, home school students did their weekly measurements today. Before the students showed up, we arrived early to measure water depth. Fishing weights attached to a measuring tape for water depth measurements is another one of Martin's homemade devices. Mean water depth including ice was 17 meters (approximately 55 feet). Ice thickness alone is only .75 meters and that counts roughly 4% of the entire water depth. See below for photos.
Heat Flow at Jalpertia Pond
Mean temperature gradient
(-15.2579 C/m) x 0.05994 W/m/K = -0.91461W/m2
This is a mild heat flux.
