IDENTIFICATION OF SEAFLOOR HABITATS IN COASTAL SHELF WATERS [PDF]
Modern, high-resolution multibeam sonar systems are capable of mapping acoustic backscattering strength coinciding with fine bathymetry, which improves substantially the capability of sonars to discriminate different types of seafloor habitats.

Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).

Magnetic Signature of Oceanic Transform Faults and Their Fracture Zones
Abstract Oceanic transform faults (TFs) offset mid‐ocean ridges, juxtaposing different‐aged crust and causing fracture zones (FZ) crossing ocean basins. Mounting evidence challenges the consensus that TFs are conservative plate boundaries, instead supporting the existence of extensional tectonics and two phases of magmatism.

Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV MARIA S. MERIAN during cruise MSM55 [PDF]
Multibeam bathymetry raw data using the ship's own Kongsberg EM 122 multibeam echosounder was not continuously recorded during RV MARIA S. MERIAN cruise MSM55. Data were recorded on 8 days between 13.06.2016 and 29.06.2016 at different locations.

Seabed Classification Using Multibeam Echosounder Measurement Data
Abstract Multibeam Echosounder (MBES) utilizes acoustic waves emitted to the seafloor through a transmitter or transducer and records its reflective. The information obtained by MBES are depth data and the scattering value of the acoustic signal reflected by the object or the seabed, called backscatter.

The Deep‐Sea Preyscapes of Mammalian Top Predators
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

Applications of Multibeam Backscatter: Using Multibeam Echosounder Backscatter to Characterize and Map Seafloor Features in Shallow and Deep Water [PDF]
Recent developments in multibeam echosounder backscatter processing are now included in most commercially available processing software. These tools allow end users to produce properly corrected backscatter mosaics and add more robust qualitative and ...

A Multibeam-Based SLAM Algorithm for Iceberg Mapping Using AUVs
Using autonomous underwater vehicles (AUVs) for mapping underwater topography of sea-ice and icebergs, or detecting keels of ice ridges, is foreseen as enabling technology in future arctic marine operations.

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...
