Abiotic factors influencing soil microbial activity in the northern Antarctic Peninsula region
(Elsevier BV, 2020)Microorganisms play a key role in the carbon (C) cycle through soil organic matter (SOM). The rate of SOM mineralization, the influence of abiotic factors on this rate and the potential behaviour of SOM are of particular ... -
Geomorphological mapping of ice-free areas using polarimetric RADARSAT-2 data on Fildes Peninsula and Ardley Island, Antarctica
(Elsevier, 2016)Satellite-borne Synthetic Aperture Radar (SAR) has been used for characterizing and mapping in two relevant ice-free areas in the South Shetland Islands. The objective has been to identify and characterize land surface ... -
Insights on the environmental impacts associated with visible disturbance of ice-free ground in Antarctica
(Cambridge University Press, 2019)The small ice-free areas of Antarctica provide an essential habitat for most evident terrestrial biodiversity, as well as being disproportionately targeted by human activity. Visual detection of disturbance within these ... -
A method for assessing the physical recovery of Antarctic desert pavements following human-induced disturbances: A case study in the Ross Sea region of Antarctica
(Elsevier, 2012)With increasing visitor numbers an understanding of the impacts of human activities in Antarctic terrestrial environments has become important. The objective of this study was to develop a means for assessing recovery of ... -
Scott Base Redevelopment CEE environmental monitoring report: Year one (January 2019)
(Environmental Research Institute, The University of Waikato, Hamilton, New Zealand, 2019)An understanding of the soils and the underlying permafrost surrounding Scott Base is important to detect impacts of environmental change or human activities, such as the redevelopment of Scott Base, on the unique soil ...

An evaluation of GPS technology as a tool to aid pasture management
(The University of Waikato, 2022)In countries with temperate climates such as New Zealand and Ireland, grazing pasture plays an essential role in dairy production and farm profitability. In these climates, pasture growth occurs year-round in a seasonal ... -
The role of mānuka (Leptospermum scoparium) riparian plantings in the mitigation of diffuse agricultural nitrogen
(The University of Waikato, 2021)The disruption of nutrient cycles in agricultural settings, particularly pastoral farming, is responsible for up to 70% of the nitrogen (N) loads entering streams in New Zealand (NZ) — resulting in the widespread degradation ... -
The effects of varying intensity cultivation on soil quality in a maize cropping system
(The University of Waikato, 2020)Maize is the primary crop grown on arable land in the Waikato region, predominantly established on Allophanic soils due to their well-drained and resilient properties. Full cultivation (FC) is universally adopted in cropping ... -
Spatial and temporal changes in soil climate and active layer depth in the Ross Sea Region, Antarctica, 1999-2018
(The University of Waikato, 2020)The depth of seasonal thaw (the active layer depth) integrates a range of soil and atmospheric climate variables and has potential to provide a clear signal of a changing climate. Nine soil climate monitoring stations (SCS) ... -
The effects of irrigation on soil carbon and nitrogen stocks of pumice soils
(The University of Waikato, 2018)The use of irrigation has become important for sustaining the production of food, fibre and biofuel. In New Zealand (NZ), irrigation of pastures is increasing in areas with seasonal water deficits, such as the Central North ...
