Applying a Multi-Method Framework to Analyze the Multispectral Acoustic Response of the Seafloor
Frontiers in Remote Sensing, 2022 Improvements to acoustic seafloor mapping systems have motivated novel marine geological and benthic biological research. Multibeam echosounders (MBES) have become a mainstream tool for acoustic remote sensing of the seabed.

Assessing the use of harmonized multisource backscatter data for thematic benthic habitat mapping
Science of Remote Sensing, 2021 Legacy seabed mapping datasets are increasingly common as the need for detailed seabed information is recognized. Acoustic backscatter data from multibeam echosounders can be a useful surrogate for seabed properties and are commonly used for benthic ...

Acoustic estimates of methane gas flux from the seabed in a 6000 km2 region in the Northern Gulf of Mexico [PDF]
, 2014 Seeps of free methane gas escaping the seabed can be found throughout the ocean basins. To understand the role of methane gas seeps in the global carbon cycle—including both gas added to the atmosphere and that which is dissolved and potentially oxidized
