The Nippon Foundation—GEBCO Seabed 2030 Project: The Quest to See the World’s Oceans Completely Mapped by 2030 [PDF]
Geosciences, 2018 Despite many of years of mapping effort, only a small fraction of the world ocean’s seafloor has been sampled for depth, greatly limiting our ability to explore and understand critical ocean and seafloor processes.

Geomorphometric Characterization of Pockmarks by Using a GIS-Based Semi-Automated Toolbox [PDF]
Geosciences, 2018 Pockmarks are seabed depressions developed by fluid flow processes that can be found in vast numbers in many marine and lacustrine environments. Manual mapping of these features based on geophysical data is, however, extremely time-consuming and ...

Numerical Imaging of the Seabed and Acoustic Flares with Topography and Velocity Variance
Remote Sensing, 2022 During seabed mapping, anomalous acoustic events in the seawater layer often degrade bathymetric quality. Acoustic-flare-like events that are induced by gas seepage occur accompanied by small seabed depressions known as pockmarks.
