Overview
Pressure incorporates tidal pressure gauges sampling at rates varying from 0.0667 Hz to 1.0 Hz. Each instrument also carries a housing temperature channel.
The product spans two generations of instruments: existing gauges on the Regional Cabled Array at Slope Base, Southern Hydrate Ridge, and Axial Base, and new COSZO Paroscientific Series 8000 gauges at Outer Shelf, Oregon Offshore, and Mid Slope.
Stations
The table below lists the station, location code, and channels for the data.

Entries without a link under Channel are data that will be available once COSZO comes online.
Additional Data
Absolute pressure data from Axial Base, served through the same OOI infrastructure.
| Site | Station | Location | Data type | Channel |
|---|---|---|---|---|
| Axial Base | OO.AXBA1 | 10 | Absolute pressure | UDO (0.0667 Hz) |
| Axial Base | OO.AXBA1 | 10 | Housing temperature | UK1 (0.0667 Hz) |
Data Access
More station information, data quality status, and deployments are available through the GitHub webpage: github.com/coszo-hub/absolute-seafloor-pressure.
Scripts for detiding and drift-correcting the data are available through the COSZO GitHub.
Raw pressure data are released within 24 hours of acquisition.
