LAST CHANGED : 2023/12/22 CRUISE NAME(S) : FKt231202 CRUISE DATES : 2023/12/03 to 2023/12/15 SHIP NAME : Falkor (too) PORTS : Balboa, Panama to Golfito, Costa Rica CHIEF SCIENTIST : Beth Orcutt DATABASE NAME : a_ftoo DATA FILES : ftoo2023_336_32340.raw to ftoo2023_348_07200.raw STATUS : to do done ------ ----------- averaged [ X ] at sea loaded [ X ] at sea NOTE: heading correction instrument exists NOTE: time-dependent heading corrections applied IN the ensembles (see cal/rotate/ens_hcorr.ang) check heading correction [ X ] calibration [ X ] edited [ X ] re-check heading correction [ X ] check editing [ X ] figures [ X ] INSTRUMENT : wh300 ACQUISITION : PROGRAM : uhdas PROCESSING : python LOGGING : PARAMETERS : BT : bottom track mode (on or off) SI : sampling interval or averaging period for ensemble (sec) NB : number of bins BL : bin length (m) TD : transducer depth (m) BK : blanking length (m) HO : heading offset applied by DAS (deg) HB : heading bias (deg) CRPH : compensation for roll-pitch-heading, 1:on, 0:off) yy/mm/dd hh:mm:ss BT SI NB BL TD BK HO HB CRPH 2023/12/03 09:01:00 on 120 70 2 7 2 -1.33 0.00 0001 2023/12/05 19:55:55 off 120 70 2 7 2 -1.33 0.00 0001 HEADING : PRIMARY : heading from gyro1 CORRECTION : heading correction from seapath NOTE: time-dependent heading corrections applied IN the ensembles (see cal/rotate/ens_hcorr.ang) POSITIONS : gps positions from posmv_gps CALIBRATION : (check original processing parameters) (1) transducer alignment original transducer alignment: -1.33 additional rotation 0 final transducer angle is: -1.33 (2) scale factor original scale factor 1 additional scale factor (none) (3) ADCP (dx=starboard, dy=fwd) meters from GPS original: 1 -14 correction 0 0 final offset 1 -14 COMMENTS : No additional calibrations are needed. Acquisition parameters are consistent with recent cruises. Gaps in heading correction required patch_hcorr.py to be run. Data below the bottom was removed, as well as small bits of data at the bottom of the sonar's range.
