Laguna Blanca Refuge, Bolivia

Experimental Stations:
Each experimental station consisted of two clear plastic squares, about a foot and a half on each side and open on the top, attached to which was a specially made piece of plexiglass, suspended horizontally within the square, about 8 inches off the ground. In each pair of chambers, one piece of plexiglass let UV through; the other blocked it.

About half of the dozen or so stations were in good enough shape to provide useful results. In some, the plexiglass had been stolen, most likely by local people who thought they would make good windows. In others, the plexiglass had collapsed, partially or fully, perhaps because of being weighed down by snow during the winter. Some had been completely destroyed by the fierce winds that blow here every afternoon. And one was completely underwater.

Later in the expedition, team members will return to each station, collect samples of the organisms underneath them where possible, and remove the remains of the destroyed stations. Some will be rebuilt and placed back on the lakeshore to be examined next year.

This is the refuge where we are staying. The sun has just come up; that's why there are no people in the picture.

Matthieu (l), Nathalie, Rob, Edmond and Cristian examine on of the partially collapsed stations.

Another collapsed station, but it may be possible to collect some sample from the corner sticking up off the ground.

This station was one of the best. The plexiglass had dropped a bit, but it wasn't touching the water.

This is one of the stations destroyed by wind.

This station, by the shore of Laguna Verde, was in the best shape of all of them. Although Laguna Verde is windier than Laguna Blanca, team members last year had built a wall to protect the experiment from the wind.

This station was underwater. Last winter was brutal and there was a lot of snow. The level of the lakes had risen quite a bit.

Those of us willing to get up at 5:30 or 6:00 am (which is not many) are greeted every morning by a beautiful sunrise. This is Laguna Verde mountain, which we see out the windows of the refuge.

I did not think I would start writing so soon upon arrival...
