Synchronization of distributed measurements in a borehole

A method of synchronizing distributed measurements in a borehole, the method comprising:

• disposing a known number of wired segments coupled together by couplers in the borehole;
• disposing nodes along the wired segments, the nodes being disposed at two or more of the couplers or between couplers and each node comprising a local clock and configured to measure or relay information obtained in the borehole to a surface processing system;
• generating a time-stamped signal at an nth node based on the local clock of the nth node;
• receiving the time-stamped signal at the surface processing system;
• and
• the surface processing system computing a time offset between a master clock associated with the surface processing system and the local clock of the nth node.
