Submarine confinement is a key element in most underwater communication application. Acoustic communication of movable submarine networks face with many unmatched inquisitive like long arch, high communication power consumption and convergence mobility. Unrushed signal enlargement allows multiple packets to coordinate travel through the submarine channel, which is harsh to improve the overall t...

This paper provides an overview of the CLAM project, which aims at developing a collaborative embedded monitoring and control platform for submarine surveillance by combining cutting edge acoustic vector sensor technology and 1D, 2D, 3D sensor arrays, underwater wireless sensor networks protocol design, advanced techniques for acoustic communication, new solutions for collaborative situation-aw...

Meltwater from the Greenland Ice Sheet often drains subglacially into fjords, driving upwelling plumes at glacier termini. Ocean models and observations of submarine termini suggest that plumes enhance melt and undercutting, leading to calving and potential glacier destabilization. Here we systematically evaluate how simulated plume structure and submarine melt during summer months depends on r...

Successful submarine operations—those that accomplish the mission while maintaining security and safety—depend on numerous factors. Among the most critical elements driving success are the effectiveness of team behavior and the ability to understand when this behavior breaks down such that this degradation can be mitigated or avoided. While underway, submarine Commanders and other leaders must ...

When tasked with the development of a large and complex system of systems it is necessary that a project operates according to current best practice in all domains including systems engineering. These practices have been documented by organisations such as INCOSE and the International Organisation for Standardisation (ISO). Model-based systems engineering (MBSE) is currently considered a best p...

In late 2013, the Submarine Force decided to modernize the 1990's combat systems on OHIOClass submarines. In early 2014, as the Submarine Combat and Weapon Control Systems (PMS 425) Program Manager, I realized that due to the process we use for developing software and hardware, it would take until 2022 to modernize all SSBN combat systems. Based on this lengthy timeline, I challenged my team "H...

In coastal regions, the study of karst aquifers and the ground water resource exploitation require a specific methodology and exploration and monitoring techniques. Two directions are investigated, leading to new technological and methodological developments. The first investigation axis deals with the exploration of fresh water plumes from submarine karst springs. An Autonomous Underwater Vehi...

Our objective was to apply ideas from complexity theory to derive neurophysiologic models of Submarine Piloting and Navigation showing how teams cognitively organize around changes in the task and how this organization is altered with experience. The cognitive metric highlighted was an electroencephalography (EEG)derived measure of engagement (termed NS_E) which was modeled into a collective R....

In 1929, an earthquake off the Grand Banks of Newfoundland initiated a submarine mass movement that sheared undersea communication cables and generated a tsunami that resulted in deaths of 27 people along the south coast of Newfoundland. This event initiated the modern realization that the seafloor is a dynamic environment with potential to do harm. More recent catastrophic examples include sub...
