BATHYMETRY AND HYDROGRAPHY

To accurately measure the water depth we have different models of echo sounders available.

Multi Beam Swath Bathymetry

The Reson 7101 Seabat MBES and Edgetech 4600 MBES can completely map the seafloor with 100% coverage, and complies with IHO Special Order, and USACE standards of accuracy.

For shallow water surveys we use the Reson or Odom Echotrac which is a small, portable, self contained unit suitable for operation in small boats that provide a digital output of the depth.

To remove the tidal effects from measured water depth we can use recording, automatic tide gauges. Alternately, if accurate predictions are available, we can apply a tidal correction correlated to the nearest standard port.

Seafloor Mapping

To map the sea bottom features, or as an aid to a bathymetric survey we can provide Edgetech Side Scan Sonar recorders.

These instruments are dual channel scanning sonar that can display an image of the sea floor, and bottom features such as reefs, trenches, cables, pipelines, well heads and wrecks can be detected..

Side Scan Sonar is also a useful aid to geological marine studies as, used in conjunction with bottom samples, can differentiate/identify surface deposits/nodules of minerals, gravels, sand and mud..
