The Pressure of In-situ Gases Instrument (PIGI) – Software, Manuals and Hardware designs for an autonomous O2/N2 measurement system.

This release contains software for running the Pressure of In Situ Gases Instrument (PIGI). Contents include acquisition and data processing software, and technical drawings. The PIGI system was originally documented in Izett & Tortell (2020), with updates by Lowin et al. (in review).

Updates from previous version:

- new technical (CAD) drawings

- LabVIEW software that is compatible with multiple types of oxygen optodes. Technical drawings were provided by Edward Taylor (U. Georgia).
