Celebrating World Hydrography Day

TAS ’19 Meg Stewart took this photo of hydrographers preparing a small survey vessel, a “launch,” for survey work.

Often [before starting to survey], the launch drives in a circle eight in order for the positioning receivers to be “seen” by the satellites, as a stationary object is more difficult to detect than one that is moving. Setting up the day’s project using the multibeam echosounder software also takes some time but all the steps need to be done properly and to the correct specifications prior to starting the sounder. If not, the locational data will be wildly off and the depths inaccurate.
