Rates of seabed temperature change at time-series sites in study areas A-E.

Data at sites were collected during tidal cycles, including at both high and low tide, over periods of 8 to 12 hr. Time-series start and end times are hours before (−) or after (+) high tide. Minimum temperature occurred at low tide (on-bank frontal movement) and maximum temperature occurred at high tide (off-bank frontal movement). Maximum rates (°C hr−1) of temperature change (ΔT) were recorded between sequential CTD observations during flood and ebb tidal phases within each time series. See Figures 2,3,4,5,6 for locations of time-series sites (TS) and Figure 8 for temperature cross sections at sites. See Table 4 for temperature data and timing (relative to tidal movement) of the 12 stations at the time-series site in study area A.

本研究于潮汐周期内采集各监测点位的数据，采样覆盖高潮与低潮时段，单次采样时长为8至12小时。时间序列的起始与结束时刻以距高潮时的小时数标注：负号代表高潮前的小时数，正号代表高潮后的小时数。最低水温出现在低潮时段（对应近岸锋面移动过程），最高水温则出现在高潮时段（对应离岸锋面移动过程）。各时间序列内，涨潮与落潮阶段的连续温盐深仪（Conductivity Temperature Depth, CTD）观测之间，记录了水温变化（ΔT）的最大速率，单位为℃·h⁻¹。时间序列监测点位（Time-series Sites, TS）的分布位置详见图2至图6，各监测点位的水温断面分布详见图8。研究区域A内时间序列监测点位的12个监测站的水温数据及相对于潮汐运动的时刻信息详见表4。
