Abstract

Temperature, salinity, oxygen saturation and sulphide levels fluctuated widely both
seasonally and with depth at a station on the upper Derwent estuary just downstream from a
pulp and paper mill. In summer (February) oxygen saturation at the bottom reached a minimum
of about 20% and sulphide levels peaked at 11 mg L- Conditions at this time would
be expected to be lethal to a wide variety of organisms. Some of the possible causes for
these changes are discussed.
