In urban environments, shallow geothermal heating and cooling systems can play a crucial role in the transition towards renewable energy sources. One such site (USquare) is transformed military barracks Brussels, where over one hundred boreholes were drilled (~120 m) equipped with heat exchangers as part of low-enthalpy network for multi-use development project. Fourteen these fiber optic cables that provide continuous temporal monitoring downhole conditions during operation. This includes...
This study demonstrates how the sounds of subaqueous gas seeps can be used to measure volume volcanic being released into an active crater lake, weeks before eruptive period. A hydrophone placed in Poás lake recorded changes soundscape over course one month. Using new passive acoustic inversion techniques, we were able from lakebed at a sample rate 5 min, far higher than traditional sub aerial sampling techniques. Comparing these findings local seismic measurements allowed us observe...
This research aims at assessing the potential of an semi-unsupervised approach to create labeled samples for predicting deprivation probability 100x100m. We compare Machine Learning (ML) and Deep approaches (DL) with a combination Sentinel-1 (S1) Sentinel-2 (S2) data. Our results confirm that propose creating labelled using semi-supervised method works. The best performance is achieve by ML combining S2 S1 data reach overall accuracy 95.34%.
Estimations of bedrock topography below glaciers and ice thickness are vital for quantifying freshwater availability surrounding populations understanding the contribution melting to sea-level rise in context global warming. While active seismology is commonly used estimation, utilization passive methods remains relatively rare. Passive solutions offer cost-effectiveness, non-invasiveness continuous monitoring capabilities that present valuable benefits glaciological research. Over past two...
An in-depth knowledge of local geology and temperature gradient around wellbores is essential in order to characterize understand geothermal systems. Fiber-optic sensing allows for the measurement strain with high spatial temporal resolution. For downhole applications, deployment relatively easy does not interfere production, making fiber-optic based technologies attractive monitoring operations. We aim demonstrate potential distributed (DSS) fiber Bragg grating sensors (FBGs) monitor energy...
