Numerical modeling and simulation technique in time-domain for multibeam echo sounder
International Journal of Naval Architecture and Ocean Engineering, 2018 A Multibeam Echo Sounder (MBES) is commonly used for rapid seafloor mapping. We herein present a time-domain integrated system simulation technique for MBES development. The Modeling and Simulation (M&S) modules consist of four parts: sensor array signal

High‐resolution multibeam sonar bathymetry of the deepest place in each ocean
Geoscience Data Journal, 2021 AbstractOver the course of 10 months, the global Five Deeps Expedition (2018–2019) mapped ~550,000 km2 of seafloor of which 61% comprised new coverage over areas never before surveyed and ~30% was acquired from some of the ocean's deepest trenches and fracture zones.

Discovering the Fine-Scale Morphology of the Gulf of Cádiz: An Underwater Imaging Analysis
Journal of Marine Science and Engineering, 2022 The dense and deep water flow that leaves the Mediterranean Sea to the Atlantic flows through the upper and middle slope of the Gulf of Cádiz as a powerful bottom stream that models and interacts with bathymetry.

Bathymetry and Geomorphology of Shelikof Strait and the Western Gulf of Alaska
Geosciences, 2019 We defined the bathymetry of Shelikof Strait and the western Gulf of Alaska (WGOA) from the edges of the land masses down to about 7000 m deep in the Aleutian Trench.

Improved Arctic Ocean Bathymetry Derived From DTU17 Gravity Model
Earth and Space Science, 2019 The existing bathymetry map of the Arctic is a compilation of ship soundings and digitized contours. Due to the presence of all‐year sea ice, costly operations and political restrictions, dense and full coverage of the Arctic is not possible, leaving ...

Multibeam Bathymetry and CTD-Measurements in two fjord systems in Southeast Greenland [PDF]
Earth System Science Data, 2017 Abstract. We present bathymetry and hydrological observations collected in the summer of 2014 from two fjord systems in Southeast Greenland, using SS Activ with a multibeam system temporally installed over the side of the ship. Our results provide a detailed bathymetric map of the fjord complex around Skjoldungen Island and the outer part of ...
