Airborne and Spaceborne Ocean Remote Sensing

Chair Dr. David Weissman eggdew@hofstra.edu
Co-Chair (Europe) Dr. René Garello r.garello@ieee.org

Technical Scope: The challenges facing ocean remote sensing are as unlimited as the variety of sea surface dynamics and meteorological conditions across the globe, and their range of spatial and time scales. The ultimate goal is to be able to make accurate estimates of a selected set of geophysical variables, with the intention of either making predictions across time and spatial boundaries, or advancing fundamental knowledge through developing empirical relationships and/or theoretical models. Advances are constantly being sought in both our understanding of the geophysical processes themselves (the electromagnetic and microwave properties of the surface and its associated air-sea interface) and their monitoring using the vast number of specialized technologies that can be selected to concentrate on one or a few of the physical processes for accurate measurements. The blending of deployed sensor programs (satellite-based or other platforms) with geophysical monitoring demands skills in making continuous observations and real-time interpretations that never seem fully adequate. The wide range of spatial scales of the sea surface (from millimeters to kilometers) must be matched by a broad spectrum of sensor technologies that have the optimum capabilities based on their electromagnetic frequency, polarization, incidence angle, coherence, Doppler characteristics and spatial/time resolution. Progress seems to be at an exponential pace, and the more effort a specialist devotes to advancing his or her own field, the more they may feel that there is a wider gulf between themselves and their colleagues. The OCEANS Conferences and the Journal of Oceanic Engineering are valuable means for immediate contacts with colleagues and professionals in related fields, and keeping abreast of their accomplishments and gaining ideas and insights for future directions.

 

Current, Wave, and Turbulence Measurement

Chair Dr. Bruce Magnell bmagnell@whgrp.com
Co-Chair Dr. Albert J. Williams 3rd awilliams@whoi.edu
Co-Chair (Asia-Pacific) Dr. Malcolm L. Heron mal.heron37@gmail.com

Technical Scope: The Current, Wave, and Turbulence Measurement Technology Committee is concerned with methods of measuring current for studies of the general circulation; vertical and horizontal profiles of current in harbors and rivers; spatial mapping of currents in estuaries, rivers and dams; and boundary layer studies.  Our members include those who use current meters and want to know how good they are; those who test current meters to discover how good they are; and those who develop current measuring technology.  Acoustic Doppler current profilers and acoustic Doppler velocimeters have taken a major position in our technology below the surface while HF and VHF radar are used to map surface currents.  Studies of the surface boundary layer, wave motion, the bottom boundary layer, the wave boundary layer, and sediment transport require fast, small, precise, non-invasive velocity probes and acoustic Doppler and travel-time current meters are being applied there.  These instruments represent a continuation of the development of direct current sensors but other techniques including correlation sonar and drifting floats offer alternatives for current sensing.  Survivability of sensors remains an issue, particularly in harbors and where fishing is intense on the shelf.  Trawler proof mountings for ADCPs have been developed by several of our constituents and tested by others.  Horizontal current profiling is a recently employed technique to avoid losses from shipping and fishing.

 

Environmental Acoustics

Chair Timothy F. Duda tduda@whoi.edu
Co-Chair (Asia-Pacific) Ruey-Chang Wei rcwei@mail.nsysu.edu.tw

Technical Scope: The Environmental Acoustics Committee covers the theory, design and operation of acoustic systems that are strongly affected by the complexities of propagation through the environment, or are intended to measure the environment.  One focus is on the influence of temporal fluctuations and model mismatch on performance.  Another is on the effects of spatial and temporal decorrelation on array systems. Other topics include intensity and phase fluctuation, multiple scattering, sub-bottom variability, and noise (ambient or event-like).

 

Environmental Technology

Chair Dr. Toru Sato sato-t@k.u-tokyo.ac.jp
     

Technical Scope: The Environmental Technology Committee is chartered to examine the impact that oceanic engineering sensors and systems have on the ocean environs and the impact the ocean has on the performance of oceanic systems and sensors. This involves the performance prediction of acoustic and non-acoustic sensors as modified by the natural environment e.g., bathymetry interaction with active sonars, and the level of disturbance that the systems bring to the ocean, e.g., high energy levels associated with active sonars with respect to mammal behavior.

 

Environment and Observation Systems 

Chair Dr. Jay S. Pearlman jay.pearlman@ieee.org
Co-Chair, Data Standards Stephen M. Holt sholt@ieee.org
Co-Chair, Ocean and Coastal Research Dr. Hans-Peter Plag  hpplag@odu.edu
Co-Chair (Europe) Dr. Christoph Waldmann waldmann@marum.de

The Environment and Observation Systems (EOS) Technology Committee addresses the interrelationships between the oceans (and other bodies of water) and the built and other natural environments to identify and better understand ways in which engineering can contribute to environmental sustainability. To support applications and the necessary creation of knowledge for this, the EOS addresses the areas of ocean and coastal observation and water monitoring at system of systems and system levels along with the management of related observation information. The technology domain for the EOS Technology Committee is in all aspects of the complex system of systems of sensors, communication devices, storage systems, computational and other hardware elements. These entities are used in concert to improve the monitoring of the state of the Earth, to increase the understanding of Earth processes, to enhance prediction of the behavior of the Earth system, and to further the ability to understand ways in which engineering can contribute to environmental sustainability. The EOS Technology Committee will track developments in systems engineering and integration, architecture, and standards related to sensor systems, communications, data processing, data archiving and cataloging, data searching and access, data portrayal, and decision support systems. The EOS committee will be an OES interface with international activities such the European Blue Growth, the IEEE Environmental Engineering Initiative, and the Group on Earth Observation Blue Planet Initiative. As part of these interactions, the EOS committee will encourage improved understanding of the impacts of environmental information on society.

 

Information Processing and Data Fusion  

Chair William (Bill) Porto bporto@natural-selection.com
Co-Chair Arjuna Balasuriya arjuna@ieee.org

Technical Scope: The focus of the Information Processing and Data Fusion Technology Committee encompasses virtually all aspects of data presentation, database design, filtering, modeling, and analysis. This committee directly benefits from advances in computer science, mathematics, and all physical sciences. Key research areas include data fusion, neural networks, computational intelligence, artificial intelligence, and visualization tools, among many others. Though there is considerable overlap with other technical committee areas, the focus of this committee is to utilize information acquired from one or more external sources (e.g., sonar imagery) and derive/implement/apply state-of-the-art computational methods to represent this data in a meaningful manner. Information processing techniques span the range from graphical user interface design to evolution of models that optimally classify ocean mammal signals.

 

Innovative Technology

Chair William Kirkwood kiwi@mbari.org
     

Technical Scope: The focus of the Innovative Technology Committee is to identify and bring to the attention of the Oceanic Engineering Society developments that may have significant impact on our future but that are not yet identified with any particular existing committee.  These will be presented as papers and talks and by organization of special sessions at conferences where rapid unfolding of some innovative technology has produced many embodiments of the new technology.  Often the innovative technologies will come from other fields such as physics, computational science, materials, and social networks.  The characteristic of this committee is outward looking for things not presently recognized within existing other committees.

 

Numerical Modeling, Simulation, and Data Visualization

Chair Professor Gopu Potty potty@egr.uri.edu
Co-Chair Professor Ananya Sen Gupta ananya-sengupta@uiowa.edu

Technical Scope: The technology focus of the Modeling, Simulation, and Visualization Technology Committee encompasses all activities and products associated with computer oriented modeling, simulation and databases within ocean engineering and science. The Committee identifies three major issues to be focused on in the next few years. The first one concerns quality control in existing and developing databases and their user interfaces. The second relates to the need for a better description of applicable models, introducing the notion of an informal “sunset law” for their codes. The third issue is attainment of a greater interdisciplinary interaction with workers in the other technical fields under OES cognizance. The Committee considers the activities in its domain to be primarily a service tool for solving concrete problems in the other areas of the ocean engineering arena, and intends to serve as a bridge - in a advisory capacity - between application needs and solution means.

Underwater Cables and Connectors

Chair Dr. M. A. Atmanand  atma@niot.res.in

Technical scope: The technology foci of the Underwater Cables and Connectors Technology Committee are engineering activities and products associated with underwater telecommunications and cables including those that use optical fibers. The fiber optic telecommunications focus subsumes systems, networks, and underwater observatories, including transoceanic and festooned fiber applications, and the revitalization and reuse of first- and second-generation fiber optic technologies for acoustic information and data transfer for scientific ocean engineering.  Also included in the focus are development and use of underwater vehicles for repair, observation, and maintenance of underwater cable technology and associated sub-systems. The connectors focus recognizes that connections to instruments and to one another must sometimes be made underwater, not simply submerged after being assembled in air.  The underwater connector is a highly evolved, relatively expensive component used extensively in ocean engineering.  The connector focus thus involves various materials, their electrical and mechanical properties, long-term integrity in a harsh environment, and operations involving disassembly, sometimes underwater, and the recovery of separated cables and instruments for potential redeployment.  Also included in the focus are seals, marine corrosion, watertight integrity, electrical and optical continuity, and impedance matching, all of which may be critical in such devices.  The committee provides a focal point for technical information exchange and promotes cooperation and coordination among fiber optic component manufacturers, connector manufacturers, and installers serving the telecommunications, ocean science, oil and gas industry, government, and special applications communities.

 

Underwater Communication, Navigation, and Positioning

Chair Dr. Milica Stojanovic millitsa@ece.neu.edu
Co-chair Lee Freitag lfreitag@whoi.edu
Co-Chair (Europe) Christophe Laot Christophe.Laot@telecom-bretagne.eu
Co-Chair (Asia-Pacific) Mandar Chitre mandar@arl.nus.edu.sg

Technical scope: The technology domain of the Underwater Communication, Navigation, and Positioning Technology Committee includes all aspects of information transmission underwater (acoustic, optical, radio).  Topics include, but are not limited to, propagation and communication channel modeling; link-layer techniques (modulation/ detection, coding, signal processing methods such as equalization, synchronization, and array combining); network-layer techniques (channel access and sharing, routing, transport control); and functions of localization, navigation, and positioning as they relate to the overall architecture and mission of autonomous underwater systems. 

 

Unmanned Maritime Vehicles and Submersibles

Chair William Kirkwood kiwi@mbari.org
Co-Chair (Asia-Pacific) Hayato Kondo hkondo@ieee.org
Co-Chair Dr. Hanu Singh hsingh@whoi.edu

 Technical Scope: Autonomous Underwater Vehicles are unoccupied but may be under completely autonomous control or may have periodic communications with a controller at the surface by radio or underwater through acoustic communication.  Data may be acquired by the AUV for internal storage, for internal analysis and programmed response, or may be returned to the controller in real-time or pseudo real-time.  Propulsion, power, materials, sensors, navigation, and operational constraints are issues with AUVs.  When a subsurface vehicle is occupied it is a submersible and a new set of constraints is critical such as life support, ports for viewing and penetrators for mechanical arms or electrical control of experiments.
