assistance of brandi (uw science tech) and knudesn techs, we have now
the correct settings (ping rate) to correctly compensate for heave
(motion of the ship up and down). this way, the software can plot the
ocean bottom flatly, if it is flat.
this image shows how the data looked before (on left) and after (on
right) we made this correction. we are quite pleased as the second
half of the cruise will collect this better-cmpensated data... woot
woot.
to give brandi, bran, and tim credit, they had, the night before,
figured out how to process the data to compensate for this. this took
many days with conversations with the person who wrote the software
they were using to do the processing (sioseis and seisee, linux and
windows, along with kingdom suite, windows). this processing will need
to be done eventually on all the data, as we are collecting the raw
unprocessed segy files... but the binary file plotted on the software
during acquisition is correct now (what the screen dump shows in this
image). thanks all.
