Dynamic Draft Survey (Vessel waterline with respect to vessel reference frame and vessel speed) The dynamic draft survey was performed during the Sea Acceptance Test (SAT) offshore of Charleston, South Carolina in March of 2006. Representatives from the NOAA Aviation and Marine Operations (NMAO) performed the survey and evaluated the results. The dynamic draft was determined using the reference surface method as per the NOS Field Procedures Manual. Results of the dynamic draft survey are entered into the CARIS vessel configuration file, NF_7125.hvf Tabular Summery of Dynamic Draft Results Dynamic Draft Table, R352_MB.hvf 90
Calibration Survey Information A patch test was performed three times for the 7125. Each time the patch values were not consistent throughout the data. A representative from Reson was onbard for the mobilization, calibration and data acquisition for the cruise. The representative was unable to determine the reasoning for the inconsistencies in patch values. The data was later delivered to Reson B.V. to resolve the issues. Reson determined that the problem was caused by the real time Reson SVP70 sound velocity sensor reporting wrong sound velocity values to the 7-P processor, even though the sound velocity values observed were close to values measured by the SBE-19. Additionally the angle values reported by the 7125 were not right. Instead of the normal 128.1 degree swath width, the 7125 reported a swath width of 131.2 degrees. To address this, Reson applied a 0.2 degrees correction to the outer beams. This was achieved by changing the sound velocity profile at the sonar head by 1 m/s to create an artificial thermo cline during post processing. Reson performed the biases calculations in PDS2000. The CARIS vessel configuration file NF_7125.hvf was updated with the values obtained from the Reson patch test. These values were used for NF-09-01-USVI post-processing.

Conduct SV observations as often as necessary to monitor changing conditions and acquire a SV observation at the conclusion of calibration proceedings. If SV measurements are measured at the transducer face, monitor surface SV for changes and record surface SV with profile measurements.
