Most of the techniques are based on the amplitude related techniques, whereby the amplitude of the received echo is used to detect objects within specified bounds. Amplitude techniques however are prone to interference and attenuation, thus limiting the capabilities of such systems. Hence, the aim of this paper is to propose a new technique that detect and track underwater moving objects using the turbulence generated by the object. Wideband signals have proven to be a very efficient alternative for merging turbulent flow characteristics and waveform design in order to describe and explain the behavior of turbulence, both artificial and natural. Therefore, constructing adapted waveforms to the natural turbulence embedded in the flow, as well as to the artificial turbulence created by an unknown underwater moving object may hold the key for a new technique for underwater object tracking. When acoustic signals with a particular Instantaneous Frequency Law traveling into underwater environment will hit a moving object, their Instantaneous Frequency Law will capture the object's artificial turbulence, as well as the natural turbulence embedded in the flow. Experimental results carried out in our reduced scale facility provide the validation of the technique.","PeriodicalId":114739,"journal":{"name":"OCEANS 2014 - TAIPEI","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133453739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also a key way for furthering advancement in the area of the International Marine Science in the 21st century. China's first experimental seafloor observatory system named Xiaoqushan Seafloor Observatory has already been set up and put into operation since April 20th, 2009. Meanwhile, the state 863 program East China Sea Coastal Seafloor Observatory System and a research project concerning key technologies in seafloor observation are supposed to be completed in 2014. The East China Sea Seafloor Observatory System (ECSSOS) including the Xiaoqushan Seafloor Observatory and the coastal seafloor observatory system will be continually expanded in the near future. ECSSOS consists of multiple junction boxes and instruments performing full-time continuous monitoring. Thus how to store, transmit, analyze and share the large amount of received data will be an issue. To deal with this issue, the authors developed the WebGIS of ECSSOS. This paper aims to introduce the background, frame structure, function modules and technologies of this WebGIS, and make a detailed explanation of algorithms applied in real-time data querying module and historical data querying module.","PeriodicalId":114739,"journal":{"name":"OCEANS 2014 - TAIPEI","volume":"18 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131838749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accompanied by the development of marine resources from nearshore extension to the deep ocean, Unmanned Underwater Vehicles (UUVs) become key instruments. Generally, UUVs include autonomous and tethered types; each has its advantages and disadvantages. Through the use of combined vehicle systems, we could take advantages of both systems. With the recent advent of seafloor observatories, deep submergence science is poised to enter a new research era where scientists will gain a more detailed understanding of various seafloor features. In this study, the Autonomous Underwater Vehicle (AUV) path planning in west Good Weather Ridge (119 55', 22 15') with the multi-beam echo sounder to obtain underwater topography. In order to observation the environment, the Remotely Operated Vehicle (ROV) is hired to carry out the terrain image at 1350m water depth in detailed.
