| Abstract: | Data obtained from a site at mean tide level on Belfast Lough, Northern Ireland, show temperature fluctuations on various timescales. Hourly means differ markedly from month to month but are similar for different depths during the same month. The short-term temperature fluctuations recorded at the surface are largely dissipated at a sediment depth of 20 cm with the proportion of total flux occurring at any depth remaining similar irrespective of the absolute temperature range. It is suggested that temperature flux ratios may provide an objective in situ assessment of beach exposure and/or water flow through sediments. A plea for a standardized methodology is made. |
