Others incorporate visualization in real-time monitoring but these are generally customized to the particular application. The ability to interactively navigate through geospatial data is common but interactive navigation along the time dimension is not. And yet, visualization of data from interacting dynamic systems is increasingly necessary to interpret biological process, physical oceanographic processes, the motion of instrument platforms (such as ships, ROVs and AUVs), and the interactions between all of these. To address this need, GeoZui3D system has been enhanced so that it seamlessly handles multiple time varying data sets: anything can be handled that can be represented through time varying surfaces, curved colored lines, curved colored tubes, arrow arrays, or color-, shape-, and size-coded points. The system can be used in both real-time and replay modes and data sets that have different sampling rates can still be visualized together. GeoZui3D can visualize events over a wide range of time scales from sensor readings at the millisecond scale to glacial movements evolving over tens of thousands of years. The system is illustrated with examples from collaborative research projects including modeled ocean and estuarine currents, tides, ship movements, changes in surface topography, AUV and ROV movements and the movements of marine mammals.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

Near real-time information about the coverage, thickness and motion of the ice cover in the navigation channel are required to coordinate icebreaking for maintaining the shipping route, and to prevent and identify ice jams as they develop. Aerial and satellite surveillance provides ice coverage data, but not thickness. This work describes a test installation in the St. Lawrence that provides real-time ice thickness, ice motion, current velocity and meteorological data from a remote site. The IPS (Ice Profiling Sonar) and ADCP Data Display System (IADDS) consists of two submerged instruments (IPS and ADCP), connected by cable to a nearby lighthouse that is equipped with a computer, weather station, appropriate display software and data transmission capability to shore and the Fisheries and Oceans Department's network. The principles and operation of the IPS and the use of an ADCP to measure ice velocity are described. The IPS and ADCP are installed at 13 m depth in the navigation channel in Lac St. Pierre in the St. Lawrence River. Real-time data from the instruments and the weather station are collected at the lighthouse site, and then formatted and transmitted to the Coast Guard headquarters in Quebec City, approximately 200 km away. Web-compatible graphs of the data are then produced for display on the Coast Guard Intranet. The structure of the control, data transmission and storage software is described, and examples are given of the data and its use for managing navigation and detecting ice jams. The results of on-site validation measurements made in the winter of 2002-2003 are also described.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

This paper proposes that instrument, data, and observatory control processes be wrapped with Web services which will provide a global software standard for these observatory functions. In addition to facilitating interoperability, state-full Web services with workflow bindings for observatory instrument and data services will enable dynamic user control of the observatory configuration and the creation of multiple virtual instrument networks within one or more ocean observatories.

The embedded steel plate cell method is executed by first inserting steel plate cells shaped like cylinders and made by welding steel plates into the seabed, then filling the interiors of the steel plate cells with sand or rock material to form the wall body, but it had never been used to build a breakwater and a design method had not been established. So in order to adopt the embedded steel plate cell method, hydraulic model testing was done to clarify the hydraulic properties of the breakwater and acting wave force and development was conducted to incorporate a design method that evaluates the decline of the strength of the ground in which the cells are embedded under repeated wave load into an actual design for the first time. This report describes the hydraulic properties of the breakwater based on the hydraulic model test results. Next it describes the design method established for repeated wave load. It concludes with an introduction to the state of execution of the breakwater.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

Aoyama et al., (2004)]. We carried out high-resolution mapping of methane plumes using a quantitative echo sounder with positioning data from GPS and also measured averaged echo intensity from the methane plumes both in every 100 m range and every one minute by the echo integrator. We obtained a number of interesting results from the present echo-sounder survey. We registered 36 plumes on echogram, ranging about 100m in diameter and 200 m to 700 m in height, reaching up to 300 m to 600 m below sea level and measured the integrated volume backscattering strength (SV) of each methane plume. The strongest SV, -33 dB, of the plumes was stronger than SV of fish school. Averaged SV tend to show the highest values around the bottom and the middle of plumes, whereas the SVs are relatively low at the top of plumes. We recovered several fist-sized chunks of methane hydrate by piston coring at the area where we observed methane plumes. Methane hydrate was recovered throughout two meters-long piston core interval, indicating thick hydrate deposits in shallow sediments near the methane plumes. A follow-up project, we are planning to measure SV of methane bubbles and methane hydrate floating in water columns through an experimental study in a large water tanks.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

As for composite breakwaters, the most significant performance requirement is usually the stability against sliding. Several criteria, such as the expected sliding distance and the exceedance probability for certain sliding distance during its lifetime, are proposed in order to optimize the design from an economical standpoint. In this paper, the verification procedures of the sliding stability are described and the most rational thresholds of these criteria according to the significance of the structures are proposed. This design method guarantees the structures for same stability irrespective of design conditions, such as extreme wave statistics, water depth, and tidal range. This procedure can be applicable not only to composite breakwaters, but also to other coastal structures.","PeriodicalId":390971,"journal":{"name":"Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat.

The survey was carried out during June 23-30, 2003 at 12 sampling stations for zooplankton. The vertical migration mechanisms of zooplankton are very variable to the taxa. In this study, after we grasp the vertical migration of zooplankton through results of echo-sounder we verify mechanisms of their vertical migration in the East China Sea, the southwestern regions and the southern Sea of Korea where the characteristics of currents are different. Also, to estimate effectively the biomass of zooplankton, we research the acoustic scattering strength according to the species. On the basis of these results we devise the most effective method for estimating zooplankton biomass through comparing and analyzing estimated by a net and echosounder. We obtained the results by a net, as a follows: zooplankton abundance ranged from 21 to 175 indiv./m3. Copepods made up about 44.1 (station 6) to 91.1% (station 1).
