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. Raw data can't be read with BPR Plotter software v.3.12. After recovery the BPR board was replaced, but the paros sensor was kept.

Position surveyed with Workboat. This instrument was deployed for 5 days (08/08/07 to 08/12/07) and was released to get BPR data during our ROV MPR survey. It then was redeployed on 08/15/07. 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. Four small gaps in the data between Jan 7-17, 2008. NSF awards OCE-0725605, 0726093.

Years 2010-2011. Paros S/N 103402. Deployment ship R/V Thompson (TN253), recovery ship R/V Atlantis (AT18-08). Mooring height (m) = 15 m. BPR ID E-046. Dynamic range (psi) 10,000. Position surveyed with Workboat. Updated the BPR firmware when we turned it around in 2010, so it should be OK now. Release wouldn't enable on first attempt. On recovery, it did not respond to any commands or ranging, but it DID release. Calculated drift rate is -17.693 cm/yr. Two 24-hour data gaps in file. RECORDED April 2011 ERUPTION! NSF awards OCE-0725605, 0726093.

Years 2011-2013. Paros S/N 51185. Deployment ship R/V Atlantis (AT18-08), recovery ship R/V Thompson (TN300). Mooring height (m) = 15 m. BPR ID E-004. Dynamic range (psi) 10,000. Position is drop target (not surveyed). Recovered by Delaney so the BPR could be serviced at PMEL between cruises. Gaps in data file. Oscillator failed in the lab during servicing. NSF awards OCE-1155849, 1155381.
