Global Bathymetry and Topography at 15 Arc Sec: SRTM15+

open access: yesEarth and Space Science, 2019
An updated global bathymetry and topography grid is presented using a spatial sampling interval of 15 arc sec. The bathymetry is produced using a combination of shipboard soundings and depths predicted using satellite altimetry.

Multisource Mapping of Lagoon Bathymetry for Hydrodynamic Models and Decision-Support Spatial Tools: The Case of the Gambier Islands in French Polynesia

open access: yesGeomatics
Precise lagoon bathymetry remains scarcely available for most tropical islands despite its importance for navigation, resource assessment, spatial planning, and numerical hydrodynamic modeling.

The role of Internal Solitary Waves on deep-water sedimentary processes. The case of up-slope migrating sediment waves off the Messina Strait [PDF]

open access: yes, 2016
Subaqueous, asymmetric sand waves are typically observed in marine channel/canyon systems, tidal environments, and continental slopes exposed to strong currents, where they are formed by current shear resulting from a dominant unidirectional flow ...

U.S. Extended Continental Shelf Cruise to Map Gaps in Kela and Karin Ridges, Johnston Atoll, Equatorial Pacific Ocean [PDF]

open access: yes, 2014
The objectives for cruise KM14-17 are to map the bathymetry of two gaps in two submarine ridges in the vicinity of Johnston Atoll. One ridge gap occurs along the informally named Keli Ridge (Hein et al., 2005) south of Johnston Atoll and the other ridge ...

Mapping Seamounts in the Gulf of Alaska [PDF]

open access: yes
Students will investigate the physical description and mapping of seamounts in a Gulf of Alaska chain as they discover how seamounts in the Axial-Cobb-Eikelberg-Patton chain can be mapped to facilitate their exploration with a manned submersible.

AUV/ASC cooperative survey [PDF]

open access: yes, 2016
In this paper we describe a solution to perform autonomous surveys taking advantage of a cooperative multivehicle setup. In the proposed configuration, an ASC provides –through an USBL- absolute positioning and communications to an AUV.
