Zusammenfassung:	Disclosed are methods and systems for calibration of an accelerometer used in a geophysical sensor while deployed in the water. An embodiment may include towing a streamer behind a survey vessel in a body of water, wherein the streamer comprises an accelerometer; causing at least a portion of the streamer to twist; receiving data from the accelerometer at a selected plurality of times during the twist; and based at least in part on the data, determining at least one calibration parameter of the accelerometer.
