- Magnetics information occurs in the
InfoBank
as:
scattered < Activity-ID >.2## files containing time sequential information along ship tracks. metadata information about magnetic analog paper rolls, inventory of gear, deployment of gear, operation of gear, magnetic tapes, and paper printer listings - InfoBank magnetic data file names:
<Activity-ID>.20# Raw observed reading <Activity-ID>.22# Edited magnetics information with regional and residual values <Activity-ID>.23# Edited magnetics information without regional values <Activity-ID>.24# Raw gradiometer readings <Activity-ID>.26# Edited gradiometer information with regional, residual and residual difference values <Activity-ID>.28# Geometrics information
- InfoBank magnetic metadata file names:
<Activity-ID>.bathgravmag bathymetry + gravity + magnetics systems metadata <Activity-ID>.bathgravmagnav bathymetry + gravity + magnetics + navigation systems metadata <Activity-ID>.bathmagnav bathymetry + magnetics + navigation systems metadata <Activity-ID>.electromagnetometer electromagnetometer systems metadata <Activity-ID>.gravmag gravity + magnetics systems metadata <Activity-ID>.magnetics magnetics (only) systems metadata
- The <Activity-ID>.2## files do not include navigation.
- Navigation must be obtained from <Activity-ID>.0## or <Activity-ID>.6## files.
- Navigation should therefore also be extracted when you retrieve these files.
- A "time" key is associated with each record for correlation with other scattered information datasets.
