Abstract
Techniques are described for measuring gravity using towed streamers. In an embodiment, a towed streamer apparatus comprises a plurality of micro electro-mechanical system (MEMS) sensors. One or more MEMS sensors of the plurality of MEMS sensors are configured to generate gravity measurement data. The one or more MEMS sensors transmit a digitized version of the gravity measurement data to a processing unit. In another embodiment, an apparatus is configured to receive gravity measurement data via an interface that is communicatively coupled to a plurality of MEMS sensors in at least one towed streamer. The apparatus may further be configured to combine the gravity measurement data received from the plurality of MEMS sensors to compute a target gravity measurement value and detect changes in gravity based on the target gravity measurement value.
