Log File
The log file contains our rawest form of instrument data. These are daily files of all the communications between the instrument and its driver at the shore station, providing an excellent resource for interpreting and trouble-shooting data. Drivers are customized software developed to interact with an instrument.

Formats
Log files are available in TXT format. Every line begins with a timestamp (ISO8601) that indicates the time that the corresponding record was received at the shore station. There are three types of records, which can be identified by the character immediately after the timestamp: '<','>', or ' ' (space).
- The '>' indicates driver-initiated communications (e.g., commands, descriptive text).
- The '<' indicates non-data responses from the instrument (e.g., acceptance of commands, output of metadata).
- The ' ' indicates a data record (e.g., measurements). The format and contents of the data record vary significantly from one instrument to another, depending on the manufacturer and configuration choices. Common formats include comma or tab-delimited text, xml and binary (stored as hexadecimal for readability).
