Silixa will be presenting at AGU’s Fall Meeting in San Francisco, California, USA on 17 and 18 December, 2015. The first presentation, entitled Challenges in Ecohydrological Monitoring at Soil-Vegetation Interfaces: Exploiting the Potential for Fibre Optic Technologies, will detail the methodological background to a DTS based soil moisture monitoring project carried out in the United Kingdom in 2015. It will also offer an insight into data interpretation. (Session Number and Title: H42B: Hot Spots and Hot Moments at System Interfaces: Novel Sensors and Modeling Approaches for Transforming Understanding of Catchment Heterogeneity I )

Traditional solutions for monitoring soil moisture and temperature such as remote techniques and point sensors show limitations in fast acquisition rates and spatial coverage, respectively. Hence, spatial patterns and temporal dynamics of heat and water fluxes at this interface can only be monitored to a certain degree, limiting deeper knowledge in dynamically evolving systems (e.g. in impact of growing vegetation).

Fibre optic Distributed Temperature Sensors (DTS) can measure soil temperatures at high spatio-temporal resolutions and accuracy, along kilometers of optical cable buried in the soil. Heat pulse methods applied to electrical elements embedded in the optical cable can be used to obtain the soil moisture.

A detailed analysis of the data of the same same project will be presented at a poster session titled Estimation of Spatial and Temporal Variability of Land Surface Hydrological and Thermal Processes on 18 December, 2015. (Session Number: H51D; poster title: Active Distributed Temperature Sensing to Characterise Soil Moisture and Heat Dynamics of a Vegetated Hillslope)

AGU’s Fall Meeting is the largest worldwide conference in the geophysical sciences, showcasing current scientific discoveries and technologies that ensure a sustainable future.
