根据1982年8 ~ 10月8周的系泊海流计观测资料，描述了哈德逊海峡平均流和潮流的垂向结构。魁北克外强烈分层的沃茨中的剩余气流沿沿着向东南方向流动，具有高度斜压性，并集中在海岸附近（在近似内部Rossby半径的离岸长度尺度内）。在近地表（30 m）观测到的最大平均速度为0.3 m s−1。在海峡沿着巴芬岛北方侧的弱分层沃茨中，平均流为西北向。最大速度为0.1 m s−1近表面（30 m），电流振幅在100 m处降至0.05 m s−1。东南向的平均输送量估计为0.93 ±0.23 × 106 m3 s−1，西北向的输送量估计为0.82 ± 0.24 × 106 m3 s−1。在海峡的大部分区域，跨海峡余流流向魁北克海岸，流速范围为0.02至0.1 ms−1。电流互感器
Abstract The vertical structures of the mean and tidal flows in Hudson Strait are described from moored current‐meter data collected during an 8‐week period in August to October of 1982. The residual flow in the strongly stratified waters off Quebec is directed along the Strait to the southeast, is highly baroclinic and is concentrated near shore (within an offshore length scale of approximately an internal Rossby radius). Maximum mean speeds of 0.3 m s−1 were observed near‐surface (30 m). In the weakly stratified waters on the northern side of the Strait along Baffin Island the mean flow is northwestward. The maximum speeds are 0.1 m s−1 near‐surface (30 m) and the current amplitudes decrease to 0.05 m s−1 at 100 m. The mean southeastward transport is estimated to be 0.93 ±0.23 × 106 m3 s−1 with a northwestward transport of 0.82 ± 0.24 × 106 m3 s−1. Over most of the Strait the across‐channel residual currents are directed towards the Quebec shore with velocities ranging from 0.02 to 0.1 ms−1. Current var...
