Developing an acceptance test for non-hydrographic airborne bathymetric lidar data application to NOAA charts in shallow waters [PDF]
, 2013 Hydrographic data of the National Oceanic and Atmospheric Administration are typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for nearshore areas.

Submarine depositional terraces at Salina Island (Southern Tyrrhenian Sea) and implications on the Late-Quaternary evolution of the insular shelf [PDF]
, 2018 The integrated analysis of high-resolution multibeam bathymetry and single-channel seismic profiles around Salina Island allowed us to characterize the stratigraphic architecture of the insular shelf.

Limnology and Oceanography: Methods, EarlyView.Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...

Gravity inversion for sub-ice shelf bathymetry: strengths, limitations, and insights from synthetic modeling [PDF]
The CryosphereSub-ice-shelf bathymetry strongly influences ice shelf stability by guiding melt-inducing water masses and through pinning points that resist the flow of the overriding ice.

Seafloor Segmentation Based on Bathymetric Measurements from Multibeam Echosounders Data [PDF]
, 2003 Bathymetric data depicts the geomorphology of the seabottom and allows characterization of spatial distributions of apparent benthic habitats. The variability of seafloor topography can be defined as a texture.

Remote Sensing in Ecology and Conservation, EarlyView.A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

The Development of A Rigorous Model for Bathymetric Mapping from Multispectral Satellite-Images
Remote Sensing, 2022 Models for bathymetry retrieval from multispectral images have not considered the errors caused by tidal fluctuation. A rigorous bathymetric model that considers the variation in tide height time series, including the tide height calculation and ...
