Future directions in hydrography using satellite-derived bathymetry [PDF]

open access: yes, 2013
Satellite remote sensing provides useful reconnaissance tool for mapping near-shore bathymetry, characterizing a coastal area and monitoring any seafloor changes that may have occurred since the last hydrographic survey of the area.

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Spaceborne active-passive optical fusion bathymetry in coastal waters: the implications of ICESat-2 photons

open access: yesInternational Journal of Digital Earth
Up-to-date bathymetric data is essential for global coastal management and protection. Conventional surveying equipment is not only inefficient but also difficult to reach on remote island coasts.

Improved Arctic Ocean Bathymetry Derived From DTU17 Gravity Model

open access: yesEarth and Space Science, 2019
The existing bathymetry map of the Arctic is a compilation of ship soundings and digitized contours. Due to the presence of all‐year sea ice, costly operations and political restrictions, dense and full coverage of the Arctic is not possible, leaving ...

OESbathy version 1.0: a method for reconstructing ocean bathymetry with generalized continental shelf-slope-rise structures [PDF]

open access: yesGeoscientific Model Development, 2015
We present a method for reconstructing global ocean bathymetry that combines a standard plate cooling model for the oceanic lithosphere based on the age of the oceanic crust, global oceanic sediment thicknesses, plus generalized shelf-slope-rise ...

The Influence of Camera Calibration on Nearshore Bathymetry Estimation from UAV Videos

open access: yesRemote Sensing, 2021
Measuring the nearshore bathymetry is critical in coastal management and morphodynamic studies. The recent advent of Unmanned Aerial Vehicles (UAVs), in combination with coastal video monitoring techniques, allows for an alternative and low cost ...

New gravity-derived bathymetry for the Thwaites, Crosson, and Dotson ice shelves revealing two ice shelf populations [PDF]

open access: yesThe Cryosphere, 2020
Ice shelves play a critical role in the long-term stability of ice sheets through their buttressing effect. The underlying bathymetry and cavity thickness are key inputs for modelling future ice sheet evolution.

Monitoring Near-Shore Bathymetry Using a Multi-Image Satellite-Derived Bathymetry Approach [PDF]

open access: yes, 2015
Two advanced survey systems for hydrographic surveying are multi-beam echsounder (MBES) and airborne lidar bathymetry (ALB). Compared to more traditional hydrographic surveying methods, these systems provide both highly accurate and a dense coverage of ...

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.
