Steps To Perform Bathymetric Surveys

What is Bathymetric Survey?

• Bathymetric is the study of the floor of a
  waterbody, which includes mapping of features on
  charts to offer details on water depth. These
  charts are usually made to help navigation and
  inform dredging activities. For instance, during
  maintenance of navigational channels. It is used
  as an echosounder attached to the survey board.
  They also analyze and define the tides,
  surroundings, currents, and shorelines to make a
  better model of the area features overall.

1. Equipment Inspections and Calibration
2. Mobilize Each Equipment

• In the survey area, mobilization of all equipment
  can involve transporting the survey boat and
  launching it. This is only transport of equipment
  which can then be used on a local hire boat as
  that can be more cost-effective in some cases.

• When appearing on site, this is crucial to make
  sure equipment is in the main condition.

3. Deployment and Equipment System

• This contains the setting up of a bespoke frame
  which is applied to add all the equipment tightly
  to the boat. When the boat is moving to make sure
  high-quality data, this keeps it firmly in place.
  The transducer is involved in the underwater
  portion of this frame and the GNSS (GPS)
  transmitters are affixed at the top of the frame
  to have as great a view of the sky as potential.
  The control hardware the echosounder and the
  GNSS controllers are then linked via marine
  cables to all additional equipment and the
  control computer. The software is then placed up
  with details about the survey noted in its
  records.

4. Sound Casting

• Measurement of the speed of sound at a Width site
  to calibrate the transducer. This is because the
  speed differs with salinity and temperature it
  can considerably affect the reading of depth.

5. Begin the Survey
6. Check the Data Before Demobilization

• Whilst monitoring the depth data over the whole
  area to be surveyed, this includes driving the
  boat. This is done by following subsequent lines.
  These lines will be very close together in narrow
  waters and where the accuracy needed is high.

• This is a fast look at overall data gathered to
  see whether any apparent areas require additional
  data collection.

7. Demobilize
8. Process the Data

• Power down all equipment, detach, and clean with
  fresh water.

• Utilizing specialized software, the data must be
  handled with a powerful workstation computer. Any
  inaccurate data is eliminated, and the final map
  is created.

• Bathymetric surveys will be beneficial if all the
  steps are performed effectively. The above
  information can be helpful to know more about
  these steps. These steps will guide how to make
  surveys and how to use data collected through
  them.
