AbstractThis study examines the occurrence and characteristics of high-frequency (<6h) sea level variations in the Solent, UK – a mesotidal estuarine strait located in the central English Channel. A 14-year time series (2000–2013) of sea level observations sampled at 15-min intervals from the Southampton tide gauge was analyzed. The 8 highest-energy events have a mean amplitude of approximately 0.6m and a dominant period of around 4h. These events correspond with periods of enhanced meteorological activity, namely a marked reduction in air pressure and onset of strong southwesterly-southeasterly winds. Sea level observations from tide gauges around the Solent and the wider English Channel region (23 in total) were used to assess the spatial...
