Multibeam bathymetry data of Discovery Gap in the eastern North Atlantic [PDF]

Data in Brief, 2020
We present a multibeam bathymetry dataset of Discovery Gap; a narrow gap in ridge of the Azores-Gibraltar Fracture Zone (eastern North Atlantic). The gap serves as gateway for the exchange of deep water between the Madeira and Iberian abyssal plains.

Sparse Gaussian Process SLAM, Storage and Filtering for AUV Multibeam Bathymetry

2018 IEEE/OES Autonomous Underwater Vehicle Workshop (AUV), 2018
With dead-reckoning from velocity sensors, AUVs may construct short-term, local bathymetry maps of the sea floor using multibeam sensors. However, the position estimate from dead-reckoning will include some drift that grows with time. In this work, we focus on long-term onboard storage of these local bathymetry maps, and the alignment of maps with ...
