Optimal trajectory generation in ocean flows [PDF]

open access: yes, 2004
In this paper it is shown that Lagrangian Coherent Structures (LCS) are useful in determining near optimal trajectories for autonomous underwater gliders in a dynamic ocean environment.

Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

open access: yesSedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

Multi-Auv Distributed Task Allocation Based on the Differential Evolution Quantum Bee Colony Optimization Algorithm

open access: yesPolish Maritime Research, 2017
The multi-autonomous underwater vehicle (AUV) distributed task allocation model of a contract net, which introduces an equilibrium coefficient, has been established to solve the multi-AUV distributed task allocation problem.

Characteristic Geometry of Keels in Arctic Sea Ice Ridges

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Deformation within and between sea ice floes creates pressure ridges, which compose a considerable volume fraction of the Arctic sea ice cover and complicate sea ice volume measurements. An important parameter for quantifying the ice volume contained in these deformation features is the keel shape.

Cooperative bathymetry-based localization using low-cost autonomous underwater vehicles [PDF]

open access: yes, 2015
We present a cooperative bathymetry-based localization approach for a team of low-cost autonomous underwater vehicles (AUVs), each equipped only with a single-beam altimeter, a depth sensor and an acoustic modem. The localization of the individual AUV is
