Coastal and Marine Geology Metadata and Data

Dictionaries: Data Dictionary   Metadata Dictionary


- refers to the magnetic field of a body of rock.
Local differences from the surrounding rocks are usually the primary concern.
These anomalies when used with other geophysical information (such as gravity) indicate different types of rocks and magnetic reversals.
Gradiometer information is generated by a pair of magnetometers.

Magnetics information:
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

Magnetic data file names:
