ABSTRACT: During summer, there is great spatial variability in bottom water temperature on the northern shelf of the Yellow Sea. This variability is associated with a thermal front along the shelf. Oscillatory currents from semidiurnal and fortnightly period tides transport water masses laterally, resulting in oscillations of bottom water temperature at fixed positions, sometimes with large amplitudes. Temperature variations, as demonstrated in the present work, can cause damage to bottom-cultured scallops. In particular, in the scallop sea ranching area near Zhangzidao Island, such oscillations are evident in late summer. We constructed a spatial index of aggregated temperature variability from current model results identifying how temporal variability during the summer period varies in space. This information can be useful both in selecting favorable ranching areas and designing laboratory stress experiments on aquaculture candidate species.

黄海北部陆架水温快速变化

摘要：夏季，黄海北部陆架底部水温存在很大的空间变化。这种变化与沿着架子的热锋有关。半日和每两周潮汐的振荡水流横向输送水团，导致底部温度在固定位置波动，有时幅度较大。如当前工作所示，温度变化可能会损坏底部养殖的扇贝。特别是在Zhang子岛附近的扇贝养殖区，这种波动在夏末时很明显。我们根据当前模型结果构建了一个汇总温度可变性的空间指数，用于确定夏季期间的时间可变性如何在空间中变化。
