Marine Trackline Geophysical Database for M77 Data

Description

Marine Trackline Geophysical data represented by the M77 tag are inclusive of singlebeam bathymetry, marine magnetic, and gravity data and were collected during marine cruises from 1933 to the present. These data are traditionally stored in the M77T format and are a foundational dataset for NOAA. Coverage is worldwide. One Header record and multiple Data records are available for a particular cruise/leg (port to port operation). The Header record documents both the content and the structure of the subsequent Data records, containing that part of the data that remains invariant throughout the cruise. The Data records present geophysical data (bathymetry, magnetics and gravity) with a corresponding time and position. Documentation that varies within the cruise is also included with the data records. Data are fully searchable on-line by geographic area, year of cruise, institution, platform, cruise, date or data type.
