Scanning The Ocean Floor

Mapping the deep ocean.

Scanning the ocean floor.

Scientists scanning the deep interior of earth have found evidence of a vast water reservoir beneath eastern asia that is at least the volume of the arctic ocean. Back in 1977 a very interesting discovery was made on the deep ocean floor where no light penetrates. But ocean infinity the. Geoscience australia and the search for mh370 a short film describing the processes of bathymetric mapping and side scan sonar used.

Second the data is projected to the sea floor. While most life on this planet requires sunlight to live there is an. Shipping containers on seafloor scientists surveying the bottom of the pacific ocean have discovered something they knew was there but had never seen before. While faster and more accurate than traditional methods echosounding only measures a single location directly under the ship and is inefficient for mapping large areas of the ocean floor.

However side scan sonar instruments are towed behind ships and often called towfish or tow vehicles. Researchers today published the most detailed map of the ocean floor ever produced. Data collected by satellites and remote sensing instruments were used to created a model at least twice as. One of the best systems for imaging large areas of the ocean floor is side scan sonar the basic concept is much the same as the basic echosounder.

This is achieved by explicitly taking into account the sss operation as follows. Seismic reflection and seismic refraction used to study the layers below the sea floor also produce an ocean sea floor map. Seafloor mapping also called seabed imaging is the measurement of water depth of a given body of water bathymetric measurements are conducted with various methods from sonar and lidar techniques to buoys and satellite altimetry various methods have advantages and disadvantages and the specific method used depends upon the scale of the area under study financial means desired measurement. A shipping container.

The goal of this study is to generate high resolution sea floor maps using a side scan sonar sss. First the raw sensor data is corrected by means of a physics based sss model.
