Incomplete contents:
The present study was undertaken to describe and measure the diffuse light field in a lake with high abiotic turbidity and an optically deep mixing regime. We wished to determine experimentally the extent to which high backscattering modified the distribution of algal photosynthesis down the water column, and the responsiveness of phytoplankton from such a regime to near-surface bright light. In addition to the photosynthesis-light experimental work a range of limnological measurements was performed on Tekapo and three other silt-laden lakes of the Waitaki River system: Lakes Ohau, Pukaki and Benmore. The major ionic composition of the waters in these and several other contrasting South Island lakes was examined
