For secure communications, high bandwidth applications and large step-out distances fiber optic technology is superior to electrical data transfer. Despite these significant advantages, perceived reliability of fiber optic technology especially subsea wet-mate connectors has been heavily debated in the industry. This paper examines some of the common industry concerns over fiber optics and the recent advancements in the industry that have improved the robustness and reliability of subsea fiber optic interconnections. The paper also looks at accelerated aging tests and field data that demonstrate repeatable performance of subsea connectors over hundreds of mate cycles. This paper will also present information concerning the robustness of fiber optic interconnects to handle subsea interventions and installations, highlighting recent advancements in the connector designs to allow easy and repeatable mating and demating of these devices in the harsh subsea environments. Finally, another impediment to common use of the fiber-optic connectors is the perceived technology readiness with successful deployment history. The paper dissects the relevant reliability data from the use of these connectors over the past 15 years and uncovers important inferences on the reliability of subsea fiber optic interconnects.","PeriodicalId":363534,"journal":{"name":"OCEANS 2010 MTS/IEEE SEATTLE","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117027240","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}

Prior research showed classification using the SD1(1a/b) vocalization performed 23% better compared to classification using the SD3(1) vocalization. One possible theory for this observation was the presence of a broad band buzz at the initiation of the SD1 call. It was theorized the broad band buzz of the vocalization was more continuously sampling the frequency response of the vocal production mechanism, (classically described as the filter in the source-filter model of speech) and potentially contributed to the observed increase in recognition. Experiments were performed with vocalizations provided by Hubbs-SeaWorld Research Institute and consisted of 20 SD1(1a/b) vocalizations for each of four whales (2 male, 2 female). The broadband component was hand segmented from the vocalization. Classification was performed on the full and segmented vocalizations with a Gaussian mixture model, using mel-frequency cepstral coefficient feature vectors. Using the full vocalization, overall accuracy was 75 +/- 2% using a 95% confidence interval. Using only the segmented broad band component, overall accuracy was 56 +/- 2% using a 95% confidence interval. Chance performance was 25%. These results cannot definitively support or reject a source filter model, but do point to the need for focused research to develop appropriate feature vectors for individual identification using acoustic cues.","PeriodicalId":363534,"journal":{"name":"OCEANS 2010 MTS/IEEE SEATTLE","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124203019","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}

The OTTB is located off the coast of Vancouver Island, Canada. It resides in 80m of water and covers 2-square kilometers of the seafloor A seafloor cable provides power and communication to a recoverable platform. The platform sits inside of an Integrated cabled long baseline Acoustic System (IAS), which provides precision tracking and acoustic communication throughout the OTTB arena. The facility has the tools researchers require to develop new underwater technologies, such as: oceanographic sensors, autonomous underwater vehicles (AUVs); underwater AUV docking systems; guidance, navigation and control algorithms; multiple vehicle cooperation; acoustic communication; and autonomous remote sensors. The OTTB project is a satellite off of the Victoria Experimental Network Under the Sea (VENUS) observatory in Saanich Inlet, and was originally proposed as an engineering laboratory to facilitate the development and testing of new underwater technology for use on cabled ocean observatories, and as a proving ground for demonstrating the suitability of existing technology for long term deployments in remote locations. The facility has subsequently come to fill a broader role, serving as a test facility for surveying, security and other ocean sensing applications. The first phase of the OTTB installation has been completed and operational testing is now underway. This document describes the development and installation of this unique facility and presents case studies for the first few experiments to capitalize on the capabilities of the OTTB.","PeriodicalId":363534,"journal":{"name":"OCEANS 2010 MTS/IEEE SEATTLE","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121265617","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}
