- Louis Sachar in Holes
|A Pisten Bully|
|Luana and I had fun lowering the zooplankton net into the|
hole. Yes, that is a bamboo flag pole and a spool of line serving
as our winch.
We spent the rest of the afternoon collecting samples of water and plankton from the ice hole. The water will be used to estimate the densities of bacteria and phytoplankton in the water, and the plankton net samples will be used to see what species of phytoplankton and zooplankton are there. In case you don't know, "plankton" refers to all organisms too small to swim against the current. Phytoplankton are microscopic algae, and zooplankton are tiny animals, including copepods and larvae (my favorite). It was an amazing day on the ice, and I can't wait to see what we caught!
