AUV/ASC cooperative survey [PDF]
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.

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.

Towards Autonomous Coordination of Two I-AUVs in Submarine Pipeline Assembly
Inspection, maintenance, and repair (IMR) operations on underwater infrastructure remain costly and time-intensive because fully teleoperated remote operated vehicle s(ROVs) lack the range and dexterity necessary for precise cooperative underwater ...

Development of an autonomous surface vehicle for monitoring underwater vehicles [PDF]
JAMSTEC has developed and operated several AUVs (Autonomous Underwater Vehicle) as platform for scientific investigation and explorations of seabed mineral resources. Conventionally, a support vessel monitors only one AUV during its whole dive for safety

Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Underwater Localization and Mapping Based on Multi-Beam Forward Looking Sonar
SLAM (Simultaneous Localization And Mapping) plays a vital role in navigation tasks of AUV (Autonomous Underwater Vehicle). However, due to a vast amount of image sonar data and some acoustic equipment's inherent high latency, it is a considerable ...

Underwater acoustic slant range measurements related to weather and sea state [PDF]
Underwater range measurements are key factor in underwater acoustic positioning, used in Long Base-Line (LBL) or Ultra Short Base-Line (USBL) computing techniques. These measurements are commonly carried out through acoustic communications between modems
