FKt231024 – Ultra Fine-Scale Seafloor Mapping
Seafloor mapping is integral to oceanographic research. Bathymetric data illustrate the seafloor’s depth, contours, and physical features, and it is often the first essential step in planning a successful submersible operation. The typical tool for seafloor mapping, multibeam sonar, creates three-dimensional topographical outlines—rather than visual images. Physical hardware limitations can hamper the resolution, or level of detail, of these data and cannot fully reveal important details on the seafloor. There is, though, a ground-breaking technology on oceanography’s horizon. On this expedition, Chief Scientist Dr. John Jamieson, Memorial University of Newfoundland, and his team will test the capabilities of a sonar system new to scientific seafloor mapping: Interferometric Synthetic Aperture Sonar (InSAS). This technology combines bathymetric data with acoustic imagery (“photographs” using sound instead of light) and is capable of unmatched resolutions fine enough to depict individual animals dwelling in the depths. Jamieson and his team will put InSAS through its paces on hydrothermal vent fields of the Eastern Galapágos Spreading Center as they assess its potential as a revolutionary seafloor mapping tool.
