13. What is Water Column Data?
•
•
•
•
•
Data showing features between
the multibeam echo sounder and
the seabed
Showing details which have to
weak signals for the depth
detection
Typical use; Locate seabed
leakages, e.g. gas seeps and fresh
water seeps
Locate biomass like fish schools
Wreck surveys, find details not
visible on multibeam data (e.g.
masts, anchor chains …)

14. Why analyze Water Column data?
Presentation by Terje Thorsnes, NGU,
Geilo 2013
We have seen several other
presentations showing the use and
need of water column data

19. Challenge with Water Column data
•
•
•
Many survey lines
Large areas
Huge amount of data
–
–
–
Size of depth value file (*.all) : 245 Mb
Water column file (*.wcd): 1 642 Mb
~ 12 Gb/hour
•
Time consuming to manually check
all lines
•
Brick technology can automate
analysis

20. Geocap Water Column Explorer for ArcGIS
•
Import MBES Water Column data
–
•
•
•
•
Currently Kongsberg Maritime datagrams (*.all, *.wcd)
Build Brick cube
Automatic conversion to depth
Automatic conversion to world coordinates
3D visualization
–
–
Together with bathymetry
Together with seismics
•
Use ArcGIS (ArcScene) to visualize “bricked” water column wedges.
•
Also available as module in Geocap Seafloor

Geocap Interpreter Machine for water
column data
–
–
Automatically filter away “nothing”
Use seismic interpreter techniques to automatically
find features in the water column
•
Locate seabed leakages, e.g. gas seeps, fresh
water seeps
•
Wreck surveys, find details not visible on
multibeam data
•
Locate anchor chains
Expression from seismics 3D body generation:
«Put Fire to the Fish» (or gas, freshwater etc)
