Early days (1983-1989)

The first activities related to the environmental biogeochemistry of surface waters in the CRAM started in 1984 in Lake Redon (named Redó before the revision of the official toponymy to restore the local names in the late 1990’s). They consisted in a two-year monitoring of the chemistry and the planktonic populations of the lake. This  provided the data set used in Jordi Catalan’s Ph. D. Thesis, supervised by Prof. Margalef, which was the first of a series of theses dealing with Pyrenean dynamic limnology that spans until present. In 1986, a survey of the water chemistry of 100 lakes in the Central and Eastern Spanish Pyrenees was carried out, in parallel to the study of the macrophyte populations and the littoral epilithic flora of diatoms as indicators of water quality. Simultaneously (1986-87 period), the chemistry of the atmospheric deposition was studied in four sampling stations at high altitude located along the same area.
