The vessel selected would be called upon to continue and exceed the remarkable accomplishments of Glomar Challanger and the Deep Sea Drilling Project. During 1984, the Sedco/BP 471 drillship was selected for that mission and was converted to a scientific drilling/coring vessel. In addition to a more than twofold increase in scientific laboratory and berthing accommodations in comparison to the Challanger, the following operational upgrades have been incorporated: 1. Increased drill string capability to 30,000 feet (9144 meters) by means of a tapered drill string with additional racking capacity. 2. Increased available power for dynamic positioning, pipehandling and increased transit speed. 3. Riser handling capability. 4. State-of-the-art drilling systems, including in-line heave compensator, electric top drive, \"Iron Roughneck\" and dual-drum coring winch. 5. New downhole systems, including high resolution sonar and television capabilities for reentry, and the use of downhole motors for coring and bare-rock spudding. The Sedco vessel, unofficially rechristened \"JOIDES Resolution\", has now completed several months of ODP operations with only minimal \"teething problems\". In nearly all respects the desired capabilities have been achieved or exceeded. This paper describes the improvements and discusses planned additional upgrading of capabilities.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123357063","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 goal of the development is to provide vertical sections of electrical conductivity under the ocean crust to a depth of a few kilometers. The method is an outgrowth of successful profiling experiments in which the electromagnetic source consists of an electric dipole dragged on the sea floor, and several electric receivers also on the sea floor are spaced out at various distances from the source. The electromagnetic signals propagate down from the source into the crust, laterally through the rocks and then up to the receiver. Direct propagation through the water is avoided by use of such high frequency signals that practically complete absorption of the water signals occur. The system is most sensitive for detection of layers that have a low conductivity compared to their surroundings.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125655490","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 Ranger 1 buoy, an extension of the Active Driftter concept developed at the Institute of Ocean Sciences, Patricia Bay, B.C., is an autonomous, self-propelled vehicle. It is designed to perform the functions of intelligent drifting buoys: oceanographic and meteorological data acquisition, but at the same time can self-position or travel a programmed course. The Ranger is powered by an 192 watt solar array, and hence the buoy travel will be a function of insolation. To examine the feasibility of solar-powered propulsion in the marine environment, a simulation of buoy performance under sample conditions was performed. A comparision of the solar energy budget at Stn. P (50degN,145degW) and the buoy power requirement of 36 watts shows that the Ranger buoy travelling at a net speed of 0.36ms^{-1}will cut the average annual drift by 80%. A buoy deployed at the latitude of the Hawaiian Islands would have sufficient solar energy to propel the Ranger 4100 km a year against the prevailing currents. With the projected performance in wind, a list of potential applications for the Ranger platform is given.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130526467","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 paper presents some definitions and examples of what the authors consider to be \"polluted\" or \"inhospitable\" waters. It goes on to discuss briefly some of the effects of such waters; and to recount some instances in which several of the types of problems have been encountered.

Speed sensors employed by the meters included a horizontal-axis ducted impeller (Endeco-174), vertical-axis rotor (Aanderaa RCM-4), inclinometer (General Oceanics 6011 MKII), and electromagnetic sensor (InterOcean Systems S4). Meters were deployed from June to September 1984 at 1.2 m above bottom using bottom platforms and a taut-wire mooring. Water depth ranged between 2.0 and 5.1 m during the study. Comparison of velocity records showed that near slack water when wind speed was about 5 m/s or greater and water depth was about 3.5 m or less, Aanderaa and General Oceanics meters recorded higher current speeds than did Endeco and InterOcean meters. Endeco and InterOcean meters recorded speeds that approached zero near slack water regardless of wind and water depth. However, as current speeds increased after slack water, speeds recorded by the InterOcean meter were 20 to 50 percent higher than those recorded by the Endeco meter. During low wind periods or when water depth exceeded about 3.5 m, speed readings from Endeco and Aanderaa meters showed close agreement even at slack water. At higher current speeds, InterOcean and General Oceanics meters recorded consistently higher speeds than did the Endeco or Aanderaa meters. Directional data differences were insignificant. Whereas the Endeco and InterOcean meters (as tested) appear suitable for measuring low velocities in the wind wave zone, further testing is required to determine which meter type records mere accurately at higher current speeds.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134230167","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}
