Overview

Observational study corrects clock drift in ocean-bottom seismometers, suggesting enhanced accuracy for seismic data.

Key Points

This research aims to address the non-linear clock drift in ocean-bottom seismometers to improve the accuracy of seismic data collection.
Deployed eight ocean-bottom seismometers in the Bransfield Strait for 13 months.
Utilized noise cross-correlations to assess clock drift.
Implemented careful selection of data pre- and post-processing parameters.
Calculated time shifts between consecutive days using daily Green’s functions.
Observed clock drift ranged from -15.3 to 5.4 seconds.
Identified non-linear components of drift varying between -1.2 to -0.6 seconds.
Successfully corrected clock drift across all OBSs using overlapping reference stations.
