There is a survey NC_GLOBAL.doc_110: tech. data coming from ship, I tried to apply that gyro NC_GLOBAL.doc_111: data for the calibration, it does not help for the navigation NC_GLOBAL.doc_112: that much. For the roughly on-station part, it seemed to NC_GLOBAL.doc_113: improve a little bit. But for the two north-bounds, the NC_GLOBAL.doc_114: navigation performance were even worse. Besides, the survey NC_GLOBAL.doc_115: tech. data were very noisy and there were things unexplainable. NC_GLOBAL.doc_116: (The gyro data sometimes had the value 0.6.0 type of display, NC_GLOBAL.doc_117: sometimes had 3580 type of display). I cannot trust that data NC_GLOBAL.doc_118: unless there is a better document to explain the data file NC_GLOBAL.doc_119: itself. I then tried to apply gyro gps data for the calibration. NC_GLOBAL.doc_120: After I rotate the database by gps heading offset angle file, NC_GLOBAL.doc_121: Reference layer U component seemed to improve a little bit but NC_GLOBAL.doc_122: not V component.

NC_GLOBAL.doc_212: Because ds9401 does not have many data points, we do not count that NC_GLOBAL.doc_213: cruise's calibration data. For cruise ds9402, ds9403, ens=9 have minimum std(phase) NC_GLOBAL.doc_214: and they have reasonable number of good data points. NC_GLOBAL.doc_215: Therefore, we use mean values from these two cruises as the final NC_GLOBAL.doc_216: rotation values for P18 Leg1, 2, 3. They are: NC_GLOBAL.doc_217: phase = mean([3.9633 4.1077]) = 4.0355 NC_GLOBAL.doc_218: amp = mean([1.0125 1.0071]) = 1.0098 NC_GLOBAL.doc_219: ------------------------------------------------------------------------- NC_GLOBAL.doc_220: One problem with the above calibration is that the amplitude increased after NC_GLOBAL.doc_221: angle file rotation. Therefore I tried to apply the ensemble length 11 and NC_GLOBAL.doc_222: 13. (Because this cruise has big variation for gps_heading - gyro_heading.) NC_GLOBAL.doc_223: The increased ensemble length does decrease the std(amp) but leg2 and leg3 NC_GLOBAL.doc_224: do not agree well enough. I then talked with Eric about this. He suggested NC_GLOBAL.doc_225: I should apply thermosaliniograph data througout leg3 for the temperature NC_GLOBAL.doc_226: correction, in stead of applying to the totally corrupted part at the beginning NC_GLOBAL.doc_227: of cruise. I also double checked the accuracy of thermosaliniograph data by NC_GLOBAL.doc_228: comparing with the CTD data. It turned out that CTD data matches with NC_GLOBAL.doc_229: thermosaliniograph data pretty well. The thermosaliniograph data was in Julian NC_GLOBAL.doc_230: day, not decimal day. (In Greg/PMEL's message, he said time was not in Julian day, NC_GLOBAL.doc_231: so I thought it was decimal day. Late on, I checked with him, he confirmed that NC_GLOBAL.doc_232: time WAS in Julian day.) I made the correction for both leg2 and leg3 on that NC_GLOBAL.doc_233: issue. After applying all the corrections, not only the std(amp) reduced but NC_GLOBAL.doc_234: also got the agreeable result for leg2 and leg3's calibration. I applied NC_GLOBAL.doc_235: amp = 0.993 and phase = 0.38 for further rotation.
