Years 2018-2020. Paros S/N 107673. This instrument was deployed on the W rim of the caldera (in sediment) and showed a strong deflationary signal (as it did in the last deployment). Not sure if this is due to site instabilty. Note we do not have an MPR benchmark here, so we cannot constrain the drift of this BPR. Deployment ship R/V Kilo Moana, recovery ship R/V Thompson. Mooring height = 15 m. BPR ID E-016. Dynamic range (psi) = 10,000. Position is surveyed location. Associated NSF awards OCE17-36926, OCE17-36882.

AKA NeMO2005-south. On recovery didn't reply because battery voltage was only 2V. The release reported it was horizontal when the first release command was sent (was the BPR on an unstable or tilted surface?). Data good (except for gaps Dec 31, 2006 to Jan 08, 2007), but batteries died in BPR March 20, 2009, so file ended before it was recovered on June 18, 2009. End of data file is 3/20/2009.

Position surveyed with Workboat. This is the same BPR that was NeMO2005-middle, so it still had the bad component and had a few spikes in the data. On recovery had a checksum error.

Note the data file needed to be edited by Scott Stalin before it could be read, because the BPR firmware needed to be updated. Calculated drift rate is -17.693 cm/yr.
