Advancing multi-vehicle deployments in Oceanographic field experiments
Autonomous Robots, 2019Co-Authors: António Sérgio Ferreira, José Pinto, Alex Nimmo-smith, Frédéric Py, Maria Da Costa, Monica A Silva, Tor Arne Johansen, João Borges De Sousa, Kanna RajanAbstract:Our research concerns the coordination and control of robotic vehicles for upper water-column Oceanographic observations. In such an environment, operating multiple vehicles to observe dynamic Oceanographic Phenomena, such as ocean processes and marine life, from fronts to cetaceans, has required that we design, implement and operate software, methods and processes which can support opportunistic needs in real-world settings with substantial constraints. In this work, an approach for coordinated measurements using such platforms, which relate directly to task outcomes, is presented. We show the use and operational value of a new Artificial Intelligence based mixed-initiative system for handling multiple platforms along with the networked infrastructure support needed to conduct such operations in the open sea. We articulate the need and use of a range of middleware architectures, critical for such deployments and ground this in the context of a field experiment in open waters of the mid-Atlantic in the summer of 2015.

Conclusion and Perspectives
2020Co-Authors: Hervé Claustre, Lionel Guidi, Antoine SciandraAbstract:Due to its particular characteristics, the Mediterranean Sea is often viewed as a microcosm of the World Ocean. Its proportionally-reduced dimensions and peculiar hydrological circulation render it susceptible to environmental and climatic constraints, which are rapidly evolving. The Mediterranean is therefore an ideal site to examine, in order to better understand a number of key Oceanographic Phenomena. This is especially true of the Ligurian Sea where, due to its geology, oceanic conditions are found close to the coast. As such, 30 years ago, an offshore time-series site provided a fresh impetus to a long history of marine biology research, which has generated a very important body of data and knowledge. This is the second volume, in a two-volume series, that summarizes this research. Across these two books, the reader will find 13 chapters that examine the geology, physics, chemistry and biology of the Ligurian Sea ? always with the goal of providing key elements of oceanography in a changing world.

Synthetic Aperture Sonar Primer
1997Co-Authors: Frank S. Henyey, Kevin L. WilliamsAbstract:Abstract : The goal of the Synthetic Aperture Sonar (SAS) primer is to understand the effect of the ocean water properties on the propagation of acoustic signals for frequencies and horizontal ranges that are applicable to SAS Navy systems currently being developed. The Oceanographic Phenomena being examined in this regard are internal waves and turbulence.

Internal Wave Theory, Modeling and Theory of the Internal Wave Field.
1995Co-Authors: Frank S. HenyeyAbstract:Abstract : The goal of this research is to understand internal waves in the ocean, and their relationship to other Oceanographic Phenomena, especially the dissipation of energy. Work carried out included a study of the energetics of the coastal region tidally generated internal waves we call solibores, and two topics in the formal theory of the Hamiltonian description of ocean dynamics.
