Ice dynamics simulations are used to determine ice forces on an assumed structure. The simulations examine the role of variables that can be altered by IM operations such as floe size, ice confinement and ice pressure. The results provide means for quantifying the benefits from icebreaking operations, which is a needed input for the design and optimization of IM systems. Ongoing work employs related techniques to determine icebreaking requirements and IM efficiency.","PeriodicalId":177475,"journal":{"name":"Day 4 Thu, September 20, 2012","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114861447","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}

Spring season operation at each of these sites is presented with a focus on engineering design and monitoring of conditions relative to accepted standards for safe operation. Ice profile temperatures and borehole jack strength measurements are a key parameter discussed in this paper to ensure safe operation. Date of ice road closure during a particular year or years of operation is presented for each site.","PeriodicalId":177475,"journal":{"name":"Day 4 Thu, September 20, 2012","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126876374","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}

Of particular interest is the Northeastern Baffin Bay area off West Greenland, which is a promising frontier area for oil and gas exploration. The break-up dates, along with other characteristics of the Ice-free season, are analyzed using weekly Canadian Ice Service Digital Archive ice chart data on ice concentrations and ice types. The reductions in the early summer ice concentrations occurred quite abruptly in the late 1990’s, prior to which, much higher ice concentrations prevailed back to the mid-1980’s. The underlying causes of the change in the sea ice conditions are explored in this paper.","PeriodicalId":177475,"journal":{"name":"Day 4 Thu, September 20, 2012","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116896677","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}
