Master thesis (In Norwegian) The thesis
was based on field work in the meromictic lake Sælenvannet and was finished in 1979. The work involved measuring
water chemistry and biological fluxes both in the oxic
and the anoxic zone. In addition the interface where oxygen and sulfide
coexist was given special attention (Børsheim, K.Y., Kuenen,
J.G., Gottschal, J., Dundas,
I.E.D. (1985) Microbial activities and chemical gradients in relation to the
precision of the sampling procedure. FEMS Microbiol.
Ecol. 31:337-350). Primary production was measured in the oxic
zone and sulphate reduction was measured to
characterize respiration in the anoxic zone. In the interface lithotrophic activity was demonstrated using carbon 14
rate measurements. Copies of the
thesis are available in two parts |
