Seamount resolution in satellite‐derived bathymetry [PDF]
Geochemistry, 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.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical 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
Earth 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
Frontiers 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.

Bathymetry Estimation from Satellite Altimeter-Derived Gravity Data
, 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.
