在海流模型和速度观测的约束下,对几个测深数据集进行了比较和评估。在浅海对马/朝鲜海峡,各数据集之间的均方根(RMS)差异达到20m。利用4种不同的地形资料对对马暖流进行了数值模拟试验。JTOPO1数据(MIRC,2003)给出了长期水平速度观测的最小均方根差异。然后寻求地形数据集的几个最小二乘组合,以最小化观测到的正压速度和模拟的正压速度之间的均方根差异。大多数数据集显示,与独立测深相比,西海峡有30-60米的大偏差
Several bathymetric data sets are compared and assessed with constraints of an ocean current model and velocity observations. The root-mean-square (rms) differences among the data sets reach 20 m in the shallow Tsushima/Korea Straits. The numerical experiments to simulate the Tsushima Warm Current are performed using four different topography data sets. The JTOPO1 data (MIRC, 2003) give the smallest rms difference to long-term horizontal velocity observations. Several least-squares combinations of the topography data sets are then sought to minimize the rms difference between the observed and modeled barotropic velocities. Most of the data sets reveal a large bias of 30–60 m at the Western Channel compared to independent sounding depths
