Use of remotely-derived bathymetry for modelling biomass in marine environments [PDF]

open access: yes, 2013
The paper presents results on the influence of geometric attributes of satellite-derived raster bathymetric data, namely the General Bathymetric Charts of the Oceans, on spatial statistical modelling of marine biomass. In the initial experiment, both the

Understanding satellite-derived bathymetry using Sentinel 2 imagery and spatial prediction models [PDF]

open access: yes, 2019
Optical satellite data is an efficient and complementary method to hydrographic surveys for deriving bathymetry in shallow coastal waters. Empirical approaches (in particular, the models of Stumpf and Lyzenga) provide a practical methodology to derive ...

Seamount resolution in satellite‐derived bathymetry [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2005
I compare satellite‐derived global relief data on 13 seamounts in the northeast Pacific Ocean to echosounder‐derived multibeam values from the Gulf of Alaska Seamount Expeditions and the West Coast Seamounts and Ridges Multibeam Surveys for peak height, latitude, longitude, and midsection area.

Evaluation of the Accuracy of Bathymetry on the Nearshore Coastlines of Western Korea from Satellite Altimetry, Multi-Beam, and Airborne Bathymetric LiDAR

open access: yesSensors, 2018
Bathymetric mapping is traditionally implemented using shipborne single-beam, multi-beam, and side-scan sonar sensors. Procuring bathymetric data near coastlines using shipborne sensors is difficult, however, this type of data is important for maritime ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

An Improved Gridded Bathymetric Data Set and Tidal Model for the Maldives Archipelago

open access: yesEarth and Space Science, 2021
The Maldives faces a unique range of environmental challenges. While the country is almost entirely dependent upon oceanic resources with more than 99% of the area covered by ocean, the absence of a suitable bathymetric map of the seafloor of the ...

Pan-European Satellite-Derived Coastal Bathymetry—Review, User Needs and Future Services

open access: yesFrontiers in Marine Science, 2021
Low-lying coastal zones are home to around 10% of the world’s population and to many megacities. Coastal zones are largely vulnerable to the dynamics of natural and human-induced changes.

Green Turtle <i>Chelonia mydas</i> Spatial Use Within the Gorgona National Natural Park, Colombian Pacific: Implications for Local Conservation. [PDF]

open access: yesEcol Evol
This study explores the spatial ecology of green turtles within the Gorgona National Natural Park (GNNP), providing insights into habitat preferences, movement patterns, and conservation implications for this vulnerable species in the Colombian Pacific. Ten green turtles were tracked in the GNNP using satellite telemetry, with tracking duration ranging

Bathymetry Estimation from Satellite Altimeter-Derived Gravity Data

open access: yes, 2023
Bathymetry underpins all marine and ocean research. It is common knowledge that there is a global deficit of high-resolution bathymetry based on modern acoustic techniques. Satellite altimetry enabled modeling of the global seafloor topography and revealed new morphological features in the unmapped areas of the oceans and seas.
