heterogeneity and the temporal variation of environmental conditions, hydraulic properties …

Core Ideas OZCAR is a network of sites studying the critical zone. OZCAR covers various
disciplines. OZCAR will help disciplines to work together for a better representation and …

Understanding the mixing between surface water and groundwater as well as groundwater
travel times in vulnerable aquifers is crucial to sustaining a safe water supply. Age dating …

The modeling and prediction of heat transfer in fractured media is particularly challenging as
hydraulic and transport properties depend on a multiscale structure that is difficult to resolve …

Since the first great oxygenation event, photosynthetic microorganisms have continuously
shaped the Earth's atmosphere. Studying biological mechanisms involved in the interaction …

Multiple reflection has been proven to be an effective method to enhance the gas detection
sensitivity of Raman spectroscopy, while Raman gas probes based on the multiple reflection …

Stream networks can retain or remove nutrient pollution, including nitrate from agricultural
and urban runoff. However, assessing the location and timing of nutrient uptake remains …

Transport in fractured media plays an important role in a range of processes, from rock
