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!!!

Find the four differences between Rev1 on the left and Rev2 on the right

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.

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?
