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 ...

Controlling near shore nonlinear surging waves through bottom boundary conditions

open access: yes, 2016
Instead of taking the usual passive view for warning of near shore surging waves including extreme waves like tsunamis, we aim to study the possibility of intervening and controlling nonlinear surface waves through the feedback boundary effect at the ...

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.

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 ...

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.

Alumni of the First Ten Years of Nippon Foundation/GEBCO Postgraduate Certificate in Ocean Bathymetry Training Program [PDF]

open access: yes, 2014
The Nippon Foundation/GEBCO Training Programme is a twelve-month course leading to a Postgraduate Certificate in Ocean Bathymetry (PCOB). It is held at the University of New Hampshire, USA and is helping to develop a new generation of seafloor mappers ...

The first ultra-high resolution Digital Terrain Model of the shallow-water sector around Lipari Island (Aeolian Islands, Italy) [PDF]

open access: yes, 2015
Very high resolution bathymetric map obtained through multibeam echosounders data are crucial to generate accurate Digital Terrain Models from which the morphological setting of active volcanic areas can be analyzed in detail. Here we show and discuss

The effect of trait choice on hybrid species distribution model projections under climate change

open access: yesEcography, EarlyView.
Species distribution models (SDMs) have been increasingly combined with thermal performance data to enhance their transferability and to provide a physiological explanation for the predicted geographic patterns. Yet, while it is widely acknowledged that thermal sensitivities may vary among biological traits, it remains largely unexplored to what extent

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 ...
