Primary uses of these sonar data include mapping of fish schools and other mid-water marine organisms, assessing biological abundance, identifying species, and characterizing habitat. Additionally, it is used to map underwater gas seeps and remotely monitor undersea oil spills.

2024年9月18日 · Water column sonar data focus on the area from near the surface of the ocean to the seafloor. Primary uses of these specific sonar data include 3-D mapping of fish schools and other mid-water marine organisms; assessing biological abundance; species identification; and habitat characterization.

Thanks to water-column sonar data, NOAA scientists are able to explore the ocean, understand habitats, and identify organisms that reside from the ocean surface, all the way to the ocean floor.

What is water column mapping? As with most things, it can take on different definitions depending on the user or application. At CCOM/JHC, it is a form of acoustic remote sensing that is used to explore aspects of the marine environment that are found between the …

2014年5月20日 · Here we review the wealth of studies using water column multibeam data to address questions in fisheries, marine mammal and zooplankton research as well as seeps and hydrothermal vents.

Espresso is a free and open-source app to visualize and process water-column data acquired by multibeam echosounders. The main feature of this tool is the possibility to vertically echo-integrate water-column data so as to visualize and examine acoustic anomalies. Espresso uses the CoFFee multibeam data processing toolbox (hence the name

Water-column sonar data archived at the NOAA National Centers for Environmental Information. New water-column sonar data are added regularly as they are provided to the archive. The data may be used and redistributed for free but is not intended for legal use, since it …

2014年6月9日 · Water column sonar data are collected on NOAA fishery survey vessels and academic and international fleets, and are used to assess the physical and biological characteristics of the ocean. Primary uses include 3-D mapping of fish schools and other mid-water marine organisms, assessing biological abundance, species identification, and habitat ...

Water column sonar data are collected by active acoustic (or sonar) technology and contain acoustic scattering information from the near- surface to the seafloor. Scientists use these data to assess physical and biological characteristics of the ocean, including the spatial distribution of plankton, fish, methane seeps and underwater oil plumes.

Users can identify and download water column sonar data, the acoustic backscatter from the near-surface to the seafloor, to ascertain physical and biological characteristics of the seafloor including the spatial distribution of plankton, fish, methane seeps, and underwater oil plumes.
