At the sites of existing superconducting gravimeters, the modeled gravity changes have root-mean-square (RMS) values of as much as 7 Gals, with ranges of up to 22 uGals. Variations much larger than these values can be found over large regions the globe. We find that the gravity effects are predominantly annual in char acter. We also find that the modeled responses to water loading exhibit long-period variations that could be mistaken for secular tectonic trends when observed over a time span of a few years.","PeriodicalId":39875,"journal":{"name":"Journal of the Geodetic Society of Japan","volume":"47 1","pages":"249-254"},"PeriodicalIF":0.0,"publicationDate":"2001-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64260961","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 long, continuous record from these sites enables the accumulation of observations coherently with respect to the driving tidal forces, and estimates of the ocean-loading signal can be made from these accumulated observations. Techniques like this defeat atmospheric, geometrical, and multipath effects which can have a comparable magnitude, but do not have the same period as ocean-loading. A project to estimate ocean-loading effects at sites globally was undertaken at the Geodetic Research Division of the National Geodetic Survey. The technique used in and results of that project are presented here. Emphasis will be placed on the diurnal and semi-diurnal tidal signals. Although excellent agreement with existing models is found for most sites, a large fraction, generally those at higher latitudes where the complex coastlines and poorer ocean tidal data begin to dominate, show significant differences from standard ocean-loading models.","PeriodicalId":39875,"journal":{"name":"Journal of the Geodetic Society of Japan","volume":"47 1","pages":"237-242"},"PeriodicalIF":0.0,"publicationDate":"2001-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64260862","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}
