摘要 提出了北大西洋副极地环流区域、位于北纬 53° 至 60° 之间的告别角和爱尔兰之间的体积、热量和淡水的准经向通量估计，其中存在计算误差。该数据集由 1991 年夏季英国控制体积实验在 RRS Charles Darwin 上收集的三个大约 500 公里边长的 CTD 站箱组成，并辅以 R/V Anton Dohrn 国际地球物理年调查的站来代表东格陵兰洋流 (EGC)，并给出了使用它们的理由。环流是通过应用于勘测框的逆方法确定的，来自安装在船上的声学多普勒电流剖面仪的原位电流测量形成对 EGC 强度的估计。气候风应力数据用于估计埃克曼通量。主要结果是确定整个调查区域的极地热通量为 0.28 ± 0.06 PW，以及淡水增益...
Abstract Quasi-meridional flux estimates for volume, heat, and freshwater, with computed errors, in the region of the subpolar gyre of the North Atlantic between Cape Farewell and Ireland between 53° and 60°N are presented. The dataset consists of three approximately 500-km-sided boxes of CTD stations collected as the U.K. Control Volume Experiment during summer 1991 on the RRS Charles Darwin, supplemented by stations from the International Geophysical Year surveys of the R/V Anton Dohrn to represent the East Greenland Current (EGC), and justification is given for their use. The circulation is determined by an inverse method applied to the boxes of the survey, with in situ current measurements from a vessel-mounted acoustic Doppler current profiler forming an estimate of the strength of the EGC. Climatological wind stress data are used to estimate Ekman fluxes. The principal results are the determination of the poleward heat flux across the survey region as 0.28 ± 0.06 PW, and of the freshwater gain by th...
