GeoRock 2022 Quiz
Test your knowledge on marine survey data and challenges with the GeoRock 2022 quiz! This quiz is tailored for professionals in the geophysical and hydrographic fields, focusing on various data interpretation scenarios.
- Assess your understanding of Multibeam Echo Sounder (MBES) issues
- Evaluate your knowledge on Side Scan Sonar (SSS) and Sub-bottom Profiler (SBP)
- Identify client comments and processing quirks in a fun way
What is wrong with the MBES data?
It is an SVP issue, the surveyor dropped the probe in the water, the rope was too old and broke
It is seabed migration, the survey took too long to complete
It is a latency issue, the skipper wanted to come home early
What is wrong with the SSS data?
It is an SVP issue
It is too shallow for a SSS survey
It is a thermocline issue
What is wrong with the SBP data?
It is marginal weather, the vessel is heading back to port
It is engine noise, the skipper struggles to keep the vessel on the line
It is an interference from the multibeam, the surveyor keeps touching F3
What object is detected on the SSS?
It is an exposure from a cable or pipeline
The transducer of the SSS is broken
It is an artefact from the towed TVG
What is wrong with survey?
Nothing, it is not the surveyor or the skipper’s fault. The processor used ‘Shift Ping to neighbour’ without doing a QC
The skipper drifted too fast to get the border
They lost RTK corrections during acquisition, the dam is masking the GPS antenna of the platbodem
What object is detected on the MAG?
It is a BOMB!!!
No worries, it’s just a fishing gear :)
Actually it’s just an artefact, the MAG touched the seabed, oupsi!!!

When Émeline is off
Find the four differences between Rev1 on the left and Rev2 on the right
A panel was deleted
Contours are smoother on the new revision
Trackplot colors is different because the client doesn't see the yellow
The geological model is different
Background information is different on the MBES and slope panels
The color scale is different.
KP are different
Target name is different
What is the worse?
Émeline says : "Hey I have something for you."
The data coordinator says : "When do you think you're going to finish your processing?"
The CAD/GIS charter: "Can you reexport this?"
The processor says: "The deadline is tomorrow? I'll finish processing in 14 days!"
People working remotely: "Can someone restart my computer, it's not working? "
The surveyor says: "We had a big problem with the equipment, but processing shouldn't take long."
What is the funniest comment received from a client?
On the printscreen of the SBP, I want the layer of the unit 1 in light blue, not dark blue. Can you amend all pictures of the report, the charts and the geological model?
Caption is too long. Use 1st sentence and paragraph the rest below and reference figure 15
Can you change the shading orientation of the multibeam depending on the inter-array cable orientation represented on the chartlet?
Can you change KP0 and amend all target lists and references in reports and charts?
