Tóm tắt

A variety of techniques have been used for baseline benthic habitat characterization and monitoring at marine and hydrokinetic (MHK) sites. A lack of standardization has led to expensive efforts that can be confusing for regulators and stakeholders evaluating these sites. Benthic habitat maps have traditionally been developed from a suite of geophysical data, including ultibeam echosounder (MBES) bathymetry and backscatter, side scan sonar, imagery from deployed camera systems, and/or sediment sample chemical and biological data. Integral is developing a computer vision (CV) system for automating the measurement of key physical and biological features in sediment profile image (SPI) and seafloor plan view (PV) imagery so that image-derived data can be efficiently integrated with other data sets to create standardized benthic habitat maps at MHK facilities.
