| dc.description.abstract | The possibility of using data from a cable-based observational system for long-term monitoring of barotropic flow in the Baltic Sea was investigated. Measurements were made of the induced potential differences between Visby on the island of Gotland and Västervik on the Swedish mainland and a yearlong period was studied in order to ensure the presence of seasonal fluctuations. The predictions from a 2D electric-potential model, forced by velocity fields from a shallow-water circulation model, proved to be well correlated with the observations. A winter and a summer period were selected for a thorough analysis, the results of which indicated a stronger correlation during winter. This implies that the relative importance of the barotropic forcing tends to weaken during summer. The spatial coverage of the induced potential differences for the cable region was found to encompass a considerable part of the Baltic proper. The correlation study indicated that the winter circulation in the Baltic proper showed “broad-scale” motion, whereas summer conditions were characterized by a barotropic gyre. An overall result of the investigation is that geoelectric monitoring is capable of providing useful data for oceanographic purposes. | en_US |
| dc.description.sponsorship | The authors are very grateful to Dr. Kristofer Döös for providing shallow-water data and for patient support when the modeling was in its primary stage. We also thank Prof. Peter Lundberg for his continuous support in the form of invaluable guidance on the science and the grammar. We would also like to thank Skanova, who made the measurements possible by making their cable available for our purposes. The Miljöfonden managed by the Swedish Association of Graduate Engineers supported part of this work. Valuable support for disseminating the results was given by the Stockholm Marine Research Centre and Stockholm University Donation Grants. Participation by R. H. Tyler was supported by the U.S. Office of Naval Research and the National Aeronautics and Space Administration. We appreciate the valuable comments from the two anonymous reviewers. | en_US |
