Two fascinating journal entries. Once again I delight in the scientific range of your journal. You might like to compare yours, both from the previous trip and current one, with those of other teachers, which tend to be narrower in scope, dealing only with their particular work.
So two sets of questions:
If the whistlers are following geomagnetic field lines at the speed of light, how do they spread out from the single lightening pulse to the whistle?
Do they diffuse and follow different paths like light through a prism?
Would this imply that each frequency followed a different field line?
Do the components of the pulse (the Fourier spectrum) form standing waves so that the lower frequencies must travel farther?
Would this mean that the conjugate point was actually spread out, a line segment whose length was frequency dependent?
Something completely different?
How does the the work on the impact of increasing acidity deal with mutation rates in their various fauna? (This has a unit of measure, appropriately named a "Darwin".)
Are these organisms part of your ice fishes food chain?
Is your team looking also looking at the impact of changes in dissolved gasses and PH on the ice fishes?
