USGS CMG FACS Operation Log

The Operations Log is a list of information about operation events.

For events with no duration (e.g., core, photo), use only starting time.

For events with a duration (e.g., dredges, lines, sleds, rolls, system on/off, video), use both starting and ending times.

Use the Equipment Code column to distinguish information by equipment type.

Define your Equipment Codes on the Equipment Log.

All times must be Zulu (Greenwich) time, not local times.
