Mooring Identification and Field Mooring Log

Mooring Identification

Every nearshore and offshore site (see Field Program page) deployed during this study was assigned a three- or four-digit mooring number that is used as a key to all information about the mooring and the associated data. The mooring numbers were assigned in anticipated order of mooring deployment in the field and are roughly sequential, although logistics can alter mooring deployment schedules.

Field Mooring Log

The field mooring log is the notebook of the field team that physically deploys the instrumentation at sea. The field mooring log includes the following information: mooring number, date and time deployed, date and time recovered, three-dimensional spatial location, instrument serial numbers, deployment platform, and descriptions of significant events which occurred during field operations (for example, a mooring or tripod damaged, divers needed for recovery, sensors fouled). A hard copy of the field mooring log is maintained that documents mooring deployments and recoveries. The entries in this mooring log (985, 986, 987, 988, 989, 990, 991, 992, 993, 994, 995, 996, 997, 998, 999, 1000, 1001, 1002, 1003, 1004) include USGS mooring number, date deployed, date recovered, and other documentation of each mooring and the instrumentation on it. A part of this record is available in this report (see Instrument Log).

In addition to the field mooring log, paper logbooks are maintained to track instrumentation and field deployments. These instrument logbooks are also kept for each instrument to record upgrades, failures, calibrations and other maintenance actions. The field mooring log and field instrument logbooks are not included in this report.
