Sampling of Lake Banyoles, The Home of the Olympic Rowing in 1992

Water collection from Basin C-III

May 9th 2010

Sunday May 9th was a much better morning than the previous one. Emilio had taken us out to one of the best dinners I have ever eaten, plus the German teenagers were no longer patrolling the hallways all night long. So after a great seafood dinner and a good nights rest we drove back to Lake Banyoles to sample Basin C-III, Basin C-III is a meromictic area of the lake.

Like in Lake Siso, a dinghy was rowed out to the long term research site and a profile of the water column was taken. From the profile we picked two sample depths, one above the anoxic zone and one sample in the anoxic zone.

This section of the lake is also high in biomass and clogged all 3 size filters. Notice the diffence in color on the 3.0um filter from the 3.0um from Lake Siso on my previous blog. From the color alone we can tell we have a different group of organisms utilizing different nutrients available to them.
