Details of Trapped low frequency waves on the Northern Israeli continental shelf


Dataset identification

Title of datasetTrapped low frequency waves on the Northern Israeli continental shelf
Narrative summary of datasetTime series of sea level measurements from different instruments deployed around the Haifa Bay area are analyzed. All observations indicate the existence of persistent low frequency oscillations with periods corresponding to approximately one hour and half-an-hour. These oscillations are persistent throughout most of the year and reached maximal wave heights of around 30 cm, a comparable value to tidal variations, making these oscillations an important factor in determining the average sea level elevation. The work identifies the phenomenon as resonant trapped waves which are normal modes of the continental shelf extending from Haifa promontory to Achziv Canyon. Their temporal and spatial characteristics are learned through field measurement data analysis, wavelet analysis, numerical simulations and exploration of an analytic solution. Finally, possible mechanisms for the generation of these waves are discussed. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
