Dynamics of silicon in lakes of the Taupo Volcanic Zone, New Zealand, and implications for diatom growth
(Freshwater Biological Assn, 2016)Intact sediment cores were taken from the deepest basins of 9 lakes in the Taupo Volcanic Zone, New Zealand, to investigate the factors controlling silicon (Si) concentrations in sediment pore waters and the flux of Si to ... -
Historical and contemporary perspectives on the sediments of Lake Rotorua
(Geological Society of New Zealand Inc., 2007-07)Lake Rotorua is probably the oldest continuously inundated lake in New Zealand, occupying a caldera formed by or closely associated with the eruption of the Mamaku ignimbrite and the collapse of the Rotorua caldera (Healy, ... -
Natural and anthropogenic lead in sediments of the Rotorua lakes, New Zealand
(Elsevier, 2010)Global atmospheric sources of lead have increased more than 100-fold over the past century as a result of deforestation, coal combustion, ore smelting and leaded petroleum. Lead compounds generally accumulate in depositional ... -
The nature, composition and distribution of sediment in Lake Rotorua, New Zealand
(The University of Waikato, 2007)Lake Rotorua has become increasingly eutrophic over the past 2 to 3 decades. The sediments of the lake have been shown to exert an important influence on this eutrophication process. Chemistry of the sediments has been ... -
Nitrogen-15 isotope enrichment in benthic boundary layer gases of a stratified eutrophic iron and manganese rich lake
(Springer, 2012)The applicability of the natural abundance of nitrogen gas isotope ratios was used to indicate the spatial distribution of nitrogen transformations in the water column and sediment pore waters of Lake Ngapouri, a small ...
