Abstract

This work presents a cabled system for collecting real-time seismic data on the coastal zones. It is deployed in the Western Mediterranean Cabled Observatory, OBSEA (www.obsea.es). A key component in this cabled system, COBS, is the use of IEEE standard 1588 that serves as a clock synchronization mechanism for the seismometer with Universal Time Coordinates (UTC) clock. Delivering of accurate timing to the seismometer, the seismic data can be time stamped using a UTC clock which is traceable to within the desired level of precision of sub milliseconds necessary for an accurate location of an earthquake.
