Water depth, seabed temperature, and temperature change along transects across the tidal front.

Temperature change from high to low tide is shown for the parts of transects where seabed temperature is influenced (Y) or not influenced (N) by frontal movement. Station pair groups (column 2) are numbered in each area from north to south (1–10; i.e. off-bank to on-bank). Each pair group contains up to 8 pairs of CTD stations, at which temperature was recorded at high or low tide. H Temp and L Temp are the ranges of seabed temperatures within the pair group measured at high and low tide, respectively. H-L ΔT is the range of temperature differences between high and low tides at stations within the pair group. This value is the criterion on which frontal influence is based. If the minimum value for H-L ΔT is >1.0°C, the pair group is considered influenced by frontal movement. Note that all station pairs in area D, Transect 23 were influenced. Area names (A-E) are as in Figure 1; names of transects (TXX) across the tidal front are as in Figures 2,3,4,5,6. See Figure 7 for locations of individual stations along CTD transects. Table S1 includes data for all 60 station pairs.
