摘要本文分析了在贝儿岛海峡和东北部圣劳伦斯湾收集的海流计、海平面和水文数据。从1980年7月到10月，我们计算了海峡中的一系列系泊设备，计算出进入海湾的净输送量为0.13 × 106 m3 s-1，并表明通过海峡的平均和涡动热通量代表了海湾东北部的净热量损失。估计的热量损失率低于Bugden（1981）计算的长期平均值，但如果根据输送和水温的年际变化进行调整，则变得相当。此外，1980年的数据允许在西圣莫德斯特海峡和萨维奇湾的永久验潮站相对于彼此水平，从而允许仅从海平面计算表面电流。因此，在考虑了对流垂直结构的部分影响后，可以计算进入海湾的长期冬季输送。在一个普通的冬天，它似乎...
Abstract We present an analysis of current‐meter, sea‐level and hydrographic data collected in the Strait of Belle Isle and the northeastern Gulf of St Lawrence. From an array of moorings in the Strait from July to October 1980, we calculate a net transport into the Gulf of 0.13 × 106 m3 s−1 and show that the mean and eddy fluxes of heat through the Strait represented a net loss of heat to the northeastern Gulf. The estimated rate of loss of heat is less than the long‐term mean computed by Bugden (1981) but becomes comparable if adjusted for interannual changes of transport and water temperature. Moreover, the 1980 data permit the permanent tide‐gauge stations in the Strait at West Ste Modeste and Savage Cove to be levelled relative to one another, thus allowing surface currents to be calculated from sea‐level alone. Hence the long‐term wintertime transport into the Gulf can be calculated after fractional effects on the vertical structure of the flow are considered. During an average winter it appears tha...
