High-resolution bathymetry by deep-learning-based image superresolution.

PLoS ONE, 2020
Seafloor mapping to create bathymetric charts of the oceans is important for various applications. However, making high-resolution bathymetric charts requires measuring underwater depths at many points in sea areas, and thus, is time-consuming and costly.

Bathymetric map of Heron Reef, Australia, derived from airborne hyperspectral data at 1 m resolution

, 2012
A simple method for efficient inversion of arbitrary radiative transfer models for image analysis is presented. The method operates by representing the shape of the function that maps model parameters to spectral reflectance by an adaptive look-up tree ...

Deriving Highly Accurate Shallow Water Bathymetry From Sentinel-2 and ICESat-2 Datasets by a Multitemporal Stacking Method

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Empirical models have been widely used to retrieve shallow water bathymetry from multispectral/hyperspectral satellite imagery. In traditional studies on deriving the topography and monitoring its temporal changes, a single date satellite image ...

Bathymetric data coverage and density from single-beam and multibeam echo sounding surveys using unmanned surface vehicles in shallow inland waters [PDF]

Journal of Water and Land Development
Hydrographic surveys must comply with the IHO S-44 standard. For the most stringent orders (Exclusive, Special, and 1a), 100% seafloor coverage is required, posing challenges in shallow waters near the 1 m isobath. Recent advancements in unmanned surface

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...
