The impacts of trampling and ground disturbances on Antarctic soils

Pablo Tejedo & Tanya O'Neill
Antarctic soils are particularly vulnerable to disturbance due to their biological and physical properties and naturally slow recovery rates that are suppressed by low temperatures and sometimes low moisture availability. As most human activities are concentrated in relatively small scattered ice-free areas, the potential for adverse human impacts is great. Antarctic soils provide habitat for fauna and flora which are regionally important and, in some cases, include endemic representatives. Thus, protection of this component of...

Quantifying uncertainty within an ecologically-coupled lake hydrodynamic model: Lake Wairarapa case study

Mat Allan
The present study investigated uncertainty within an ecologically coupled 1-D hydrodynamic model of Lake Wairarapa and uncertainty of total chlorophyll a (TCHLA) estimation. This uncertainty was compared and resulted from both model history matching or model parametrization (within lake) and uncertainty generated from inflowing nitrate concentrations derived from prior and posterior catchment modelling. The study indicated that catchment model calibration effort has significant implications for lake modelling uncertainty. The posterior catchment model scenario led to...
