This expedition had no major issues with underway instrumentation. As always there are a few kinks to work through but overall it was a success. With a long initial transit from Cape Town to our drilling sites and a very long transit from there to Reykjavik we were able to record two mostly complete underway data sets including navigation, bathymetry, and magnetometer data. There are a few gaps in the data during the second transit due to going through EEZs of different islands as we traveled north. The only issues with data collection during the first transit were caused by very deep water and rough seas in which the bathy could not pick up the seafloor and therefore has some gaps.
System Status:
Underway PCs
- On may 29th WinFrog2 user profile became corrupted and had to be completely reset by the MCS. This was found when computer would freeze anytime user tried to access the C: drive. Unclear what the cause was but it did occur after a few windows updates.
Navigation
- Installed new SPS365 Trimble receiver (tag # 53949) in BLO to replace SPS351(tag # 52267). The SPS351 will be kept onboard as a working spare and is stored in UWGL drawer B2 with the rest of the spare Trimble GPS cables. The new antenna was not installed and is stored in B2 as well.
- Had issues getting JRData Server to receive NMEA data from WinFrog over the network. Port 128 has rules and everything set up my the MCS to make the transfer happen but it is still being blocked by windows defender. Right now the only work around that the MCSs and I could find was to disable the firewall.
- Collected navigation data using WinFrog with no issues. Other than JRData Server and its work around, all instrumentation data connections to and from WF were stable.
