It involved on site measurements of water properties, bird observations, investigations on local sea fauna and flora and different types of mathematical modeling procedures starting from wave hindcast and ending with different types of spill analysis (oil and suspended material). The main idea was to confirm that no harm come to the bird protection area and to work out a disaster recovery plan if an accident of some kind would happened in the harbour. The present paper describes only a part of the whole set of investigations: wave and current hindcast and sediment transport balance investigations.","PeriodicalId":287811,"journal":{"name":"2004 USA-Baltic Internation Symposium","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132264486","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}

Samples from on-water spills and fuel tanks from possible sources (moored ships) were taken from the Norfolk Navy Base in Norfolk, VA (USA) and volatile organic compound (VOC) samples were taken from a multiple leaking underground fuel tank site in Hazleton, PA (USA). Individual compound stable carbon isotope ratios were measured and the data subjected to several multivariate statistical tests to determine similarity between sample hydrocarbon source(s). Multiple analysis of variance, principal components analysis and hierarchical clustering showed similarities between discreet samples at both sites and in the case of the Norfolk samples confirmed a shipboard leak. CSIA coupled with multivariate statistics was found to be a useful tool for source-apportioning hydrocarbons.","PeriodicalId":287811,"journal":{"name":"2004 USA-Baltic Internation Symposium","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134218202","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}

An accurate geoid can be used to connect the ellipsoid referenced positioning capabilities of GPS with sea-level referenced quantities. The US Naval Research Laboratory (NRL) and the Danish National Survey and Cadastre (KMS) have been developing capabilities in airborne gravity and altimetry that can simultaneously improve the geoid, provide precise water level profiles and transfer absolute vertical coordinates to tide-gages and bottom-moored inverted echo-sounder or pressure gage systems. Examples of high-precision geodesy and altimetry in the Gulf of Mexico demonstrate the general possibilities of the technique and its potential application to the Baltic. Recent airborne gravity surveys of the Baltic performed by KMS, when combined with regional historical terrestrial and marine gravity measurements and the new intermediate wavelength gravity data from the CHAMP and GRACE satellite gravity missions allow the production of a precise gravimetric geoid for the area. This msl reference can provide a unified vertical reference frame for water-level measurement systems and future advanced circulation models of water level and currents in the Baltic.","PeriodicalId":287811,"journal":{"name":"2004 USA-Baltic Internation Symposium","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129800020","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}
