As natural oil and gas seeps from the seafloor provide useful indicators of geological formations, pre-exploration surveys to detect natural emanations are getting increasingly common before conventional and expensive seismic campaigns.
The multi-mission SEA EXPLORER glider equipped with relevant sensors is a lightweight and very cost effective mean to persistently collect "in-situ" data along the complete water column.
Navigating autonomously at sea for weeks to months while collecting data, gliders avoid costly daily ship fee. Data are then transmitted by satellite in near-real time to operators located at onshore office for a better understanding of geological structures.
Following parameters, among others, can be detected:
