35,000 years of hydrological variability in northern New Zealand from speleothem magnetism
(2018)Speleothem magnetism is the study of the origin and geo-enviromagnetic significance of magnetic minerals in speleothems. Allogenic magnetic particles are transported to speleothem sites from soils and sediments by hydrological ... -
Aqueous copper bioavailability linked to shipwreck-contaminated reef sediments
(Nature Publishing Group, 2019)Pollution from the grounding or sinking of ships can have long lasting effects on the recovery and dynamics of coastal ecosystems. Research on the impact of copper (Cu) pollution from the 2011 MV Rena shipwreck at the ... -
Assessing acid rain and climate effects on the temporal variation of dissolved organic matter in the unsaturated zone of a karstic system from southern China
(Elsevier, 2018)Acid rain has the potential to significantly impact the quantity and quality of dissolved organic matter (DOM) leached from soil to groundwater. Yet, to date, the effects of acid rain have not been investigated in karstic ... -
Association of arsenic and phosphorus with iron nanoparticles between streams and aquifers: Implications for arsenic mobility
(American Chemical Society, 2015)The microbial oxidation of organic matter coupled to reductive iron oxide dissolution is widely recognized as the dominant mechanism driving elevated arsenic (As) concentrations in aquifers. This paper considers the potential ... -
Biogeochemical feedbacks to ocean acidification in a cohesive photosynthetic sediment
(Nature Portfolio, 2021)Ecosystem feedbacks in response to ocean acidification can amplify or diminish diel pH oscillations in productive coastal waters. Benthic microalgae generate such oscillations in sediment porewater and here we ask how CO₂ ...

The effects of ocean acidification on microbial nutrient cycling and productivity in coastal marine sediments
(The University of Waikato, 2022)Ocean Acidification (OA), commonly referred to as the “other CO₂ problem,” illustrates the current rise in atmospheric carbon dioxide (CO₂) levels, precipitated in large by human-related activity (e.g., fossil fuel combustion ... -
Improved determination of nitrate concentrations and flow rates in freshwater using ‘Diffusive Gradients in Thin-films’
(The University of Waikato, 2021)Nutrient pollution, particularly by nitrate, is a persistent issue in waterways. Numerous mitigation strategies have been developed to address this pollution, such as denitrifying bioreactors. The monitoring, however, of ... -
Effects of organic matter complexation on partitioning of first-row transition metals into calcite: cave-analogue crystal growth studies
(The University of Waikato, 2020)Speleothems are important archives of terrestrial paleoclimate due to their wide geographical coverage and the ability to date their growth layers using U-Th and U-Pb radiometric dating. Extensive research into various ... -
The terrestrial carbon cycle in transition: tracking changes using novel tracers on multiple timescales
(The University of Waikato, 2020)Soils store more carbon than the atmosphere and terrestrial vegetation combined, therefore, changes in soil carbon storage can affect the global carbon budget. One of the forms in which carbon is exported from soil is as ... -
Response and resilience of estuarine benthic ecosystems to anthropogenic pressures
(The University of Waikato, 2020)Human activities are altering coastal environments at local and global scales with largely unknown consequences. Catchment land-use changes increase the rates of delivery of fine sediments and nutrients to estuaries, ...
