The mesocosm experiment has officially begun! After a cold morning on the dock, the students have finished sampling for T0 – the first day of the experiment. Amy, Phil, Kiely, and Daneil went down to the dock early to remove the domes and read the light levels in the mesocosm. Afterwards, the rest of the students came down to help with the integrated water sampler, niskin casts, and with collecting their water samples. The lab is now filled with the sounds of filter rigs and classic rock as the students work hard filtering, fixing, and processing their samples.
