First DAS observations from the GeoLab fibre in Madeira, Portugal
Year: 2025
Type: article
Abstract: Distributed Acoustic Sensing allows extremely dense acquisition geometries of strain data. The GeoLab fibre, installed on the southern coast of Madeira Island, extends for ∼56 km and is exclusively dedicated to research. This fibre provides an invaluable resource for continuous data collection and analysis. Between October 26th and November 3rd , 2023, ∼7 TB of data were collected at 500 Hz with gauge length of 10.2 m at each 5.1 m. This report highlights the versatility of the GeoLab fibre and the present dataset for seismological, oceanographic, and biological research with a non-exhaustive collection of examples in various scientific domains, such as local and teleseismic events, calls from different species of baleen whales, waves and their interaction with the shoreline, ocean-bottom currents and temperatures, and anthropogenic noise sources.
