Data below the bottom was removed, as well as small bits of data at the bottom of the sonars range was removed.

Check visual oddities ------------------------------------------------------------------------------ # I ran this to look for gaps in the cruise track. plot_nav.py nav/a*.gps # I ran this to look for gaps in the heading correction. figview.py # I ran this to look for missing heading correction values or missing positions. dataviewer.py # I ran this. catwt.py catxy.py **watertrack** ----------- Number of edited points: 11 out of 12 median mean std amplitude 0.9920 0.9928 0.0160 phase -0.2500 0.0374 0.8246 ----------- **transducer-gps offset** ----------- guessing ADCP (dx=starboard, dy=fwd) meters from GPS positions from a_ftoo.agt calculation done at 2023/08/07 11:01:09 xducer_dx = -0.293893 xducer_dy = -1.088317 signal = 127.803550 ----------- # Everything looks good. No gaps in the heading correction exist, so # patch_core.py is not needed. Some data below the bottom and at the bottom # of the sonar's range will need to be removed manually. ------------------------------------------------------------------------------ ### 2. ADCP calibration ------------------------------------------------------------------------------ # So we're at a point where we do not need perform further phase calibration or a # dxdy correction. ------------------------------------------------------------------------------ ### 3. Editing points ------------------------------------------------------------------------------ # To go through the dataset and edit out bad values. dataviewer.py -e # To recompute the calibration residuals. quick_adcp.py --steps2rerun navsteps:calib --auto ------------------------------------------------------------------------------ ### 4. Check edited, calibrated dataset against original dataset ------------------------------------------------------------------------------ # Has this corrected the problems in the original? dataviewer.py -c . ../wh300 # To compare this sonar with another sonar. dataviewer.py -c ../os38nb . # The differences in water velocity I attribute to the difference in the sonar # resolution. That is, the wh300 has much higher resolution than the os38nb. ------------------------------------------------------------------------------ ### 5. Make plots and files ------------------------------------------------------------------------------ # To divvy up the cruise into sections I ran this. mkdir webpy cp ../os38nb/webpy/sectinfo.txt ./webpy/ quick_web.py --redo # Run this to extract matlab files quick_adcp.py --steps2rerun matfiles --auto # Run this to extract a netCDF file adcp_nc.py adcpdb contour/wh300 FKt230802 wh300 --ship_name "Falkor (too)" # Run this to check the headers ncdump -h contour/wh300.nc | egrep '(cruise_id|sonar|yearbase)'
