Description:
The Alliance for Coastal Technologies (ACT) Workshop on Towed Vehicles: Undulating PlatformsAs Tools for Mapping Coastal Processes and Water Quality Assessment was convenedFebruary 5-7,2007 at The Embassy Suites Hotel, Seaside, California and sponsored by the ACT-PacificCoast partnership at the Moss Landing Marine Laboratories (MLML). The TUV workshopwas co-chaired by Richard Burt (Chelsea Technology Group) and Stewart Lamerdin (MLMLMarine Operations). Invited participants were selected to provide a uniform representation of theacademic researchers, private sector product developers, and existing and potential data productusers from the resource management community to enable development of broad consensus opinionson the application of TUV platforms in coastal resource assessment and management.The workshop was organized to address recognized limitations of point-based monitoring programs,which, while providing valuable data, are incapable of describing the spatial heterogeneityand the extent of features distributed in the bulk solution. This is particularly true as surveysapproach the coastal zone where tidal and estuarine influences result in spatially and temporallyheterogeneous water masses and entrained biological components. Aerial or satellite based remotesensing can provide an assessment of the aerial extent of plumes and blooms, yet provide no informationregarding the third dimension of these features. Towed vehicles offer a cost-effectivesolution to this problem by providing platforms, which can sample in the horizontal, vertical, andtime-based domains. Towed undulating vehicles (henceforth TUVs) represent useful platformsfor event-response characterization. This workshop reviewed the current status of towed vehicletechnology focusing on limitations of depth, data telemetry, instrument power demands, and shiprequirements in an attempt to identify means to incorporate such technology more routinely inmonitoring and event-response programs. Specifically, the participants were charged to addressthe following: (1) Summarize the state of the art in TUV technologies; (2) Identify how TUVplatforms are used and how they can assist coastal managers in fulfilling their regulatory and managementresponsibilities; (3) Identify barriers and challenges to the application of TUV technologiesin management and research activities, and (4) Recommend a series of community actions toovercome identified barriers and challenges.A series of plenary presentation were provided to enhance subsequent breakout discussions bythe participants. Dave Nelson (University of Rhode Island) provided extensive summaries andreal-world assessment of the operational features of a variety of TUV platforms available in theUNOLs scientific fleet. Dr. Burke Hales (Oregon State University) described the modification ofTUV to provide a novel sampling platform for high resolution mapping of chemical distributionsin near real time. Dr. Sonia Batten (Sir Alister Hardy Foundation for Ocean Sciences) providedan overview on the deployment of specialized towed vehicles equipped with rugged continuousplankton recorders on ships of opportunity to obtain long-term, basin wide surveys of zooplanktoncommunity structure, enhancing our understanding of trends in secondary production in the upperocean.
