Site Fix was used at each hole that was cored to depth with no issues collecting and displaying location data or saving site reports. Two times we ran into the issue of a report being saved with no data(blank). The fix was to simply make the report again and the second one would save normally and overwrite the blank report.
Bathymetry
Bathy 2010 was run on all transits and used to obtain a PDR before drilling on each site. It was entirely run using Zoom(Bottom) mode with the processed SEGY data recording mode selected. We tested trying to use the manual SEGY start time option in order to more consistently capture accurate SEGY data but quickly realized that this method was not feasible.

Magnetometer
The magnetometer was run as much as possible depending on the sea conditions and permissions allowed. No connection issues occurred with the maggie and Sealink software. During L4T the breaker tripped on the port side winch just as we began to reel it in. However once reset it was brought in with no further issue.
