TL;DR: The Global Multi-Resolution Topography (GMRT) as discussed by the authors is a collection of bathymetry tiles with digital elevations and shaded relief imagery spanning nine magnification doublings from pole to pole.

TL;DR: The General Bathymetric Chart of the Oceans (GEBCO) as discussed by the authors has been updated with a new digital bathymetric model of the world ocean floor merged with land topography from publicly available digital elevation models.

TL;DR: The Nippon Foundation GEBCO Seabed 2030 Project will encourage and help coordinate and track new survey efforts and facilitate the development of new and innovative technologies that can increase the efficiency of seafloor mapping and thus make the ambitious goals of Seabing 2030 more likely to be achieved.

TL;DR: In this paper, the authors present a selection of these initiatives as best practice examples for bathymetry data collection, compilation and open data sharing as well as the Nippon Foundation-GEBCO (The General Bathymetric Chart of the Oceans) Seabed 2030 Project that complements and leverages these initiatives and promotes international collaboration and partnership.

TL;DR: In this article, the relative importance of variables that affect backscatter intensity varies at different sites, suggesting that backscatters alone alone cannot be used to quantitatively predict seabed characteristics.
