Revision History
- 20180503: Initial release
Formats
Format is .acc, consisting of comma-separated numeric values as shown in the section below.
Oceans 2.0 API filter: extension=acc
In the near future, ONC will be also sending the .acc files to IRIS, as currently done with seismometer data (102).
Examples
A sample .acc file would look as follows:

Each line contains the following information:
1 | NTP time | YYYY-MM-DD HH:MM:SS.sss format. | The time that the NTP client reports. This is reset automatically per the configured NTP refresh rate while the NTP source is accessible. |
2 | Logger time | YYYY-MM-DD HH:MM:SS.sss format. | The time that the internal logger reports. Drift should be ±60s/year. |
3 | Accelerometer X period (picoseconds) | Double precision (64 bit) floating point number. | The period of the X (first) channel of the triax accelerometer. |
4 | Accelerometer Y period (ps) | Double precision (64 bit) floating point number. | The period of the Y (second) channel of the triax accelerometer. |
5 | Accelerometer Z period (ps) | Double precision (64 bit) floating point number. | The period of the Z (third) channel of the triax accelerometer. |
6 | Accelerometer temperature period (ps) | Double precision (64 bit) floating point number. | The period of the temperature (fourth) channel of the triax accelerometer. |
7 | BPR pressure period (ps) | Double precision (64 bit) floating point number. | The period of the pressure (first) channel of the BPR. |
8 | BPR temperature period (ps) | Double precision (64 bit) floating point number. | The period of the temperature (first) channel of the BPR. |
