Data from tide gauges at Iceland and Bermuda combined with data on atmospheric pressure at both stations plus hydrographic serial observations at Bermuda are utilized to analyze sea-level variations in both regions. Residual sea-level anomalies (raw sea-level anomaly minus barometric and steric effects) are computed and discussed for Bermuda. The analysis, which indicates a periodicity of four months, is regarded as very tentative....
