Ending the Season
On January 27th, Erin and I flew back to McMurdo to begin our teams' closing of the season. John, Jen and Karen stayed in the field to winterize and close the stream's gage boxes, while we transported all of the samples collected in the field to Crary Lab where the job of preserving and processing the algae took place.
You may remember from previous journals, at each algae transect we collected four samples at five sites for each color of algae and moss. One of the samples was preserved with formaldehyde to be shipped back to the University of Colorado, CU. One sample is tested in the lab at McMurdo for chlorophyll A. Another is frozen and will be shipped back to CU, and the last is one that we performed an ash free dry mass technique to determine the amount of carbon in it. Except for the sample in formaldehyde, all had to be filtered first.
Erin and I worked in the lab all week filtering, labeling, packing, drying and weighing the samples. Permits had to be obtained to carry the samples through customs in New Zealand and back into the US. They have to be kept frozen as they travel, so special arrangements were made to be met in New Zealand and Los Angeles with fresh ice. This part of the work is extremely important. If the samples are lost or mishandled, a whole season of research could be lost. It was a busy week!
I will post a few more journals as stories come to mind, but essentially the research season has ended and my time here is coming to an end. I am just waiting now for a flight home.
