补充资料：平均海平面
| 平均海平面 mean sea level 水位高度等于观测结果平均值的平静的理想海面 。观测时间范围不同，有不同概念的平均海平面，如日平均海平面、年平均海平面和多年平均海平面等等。一些验潮站常用18.6年或19年里每小时的观测值求出平均值，作为该站的平均海平面。 因为观测值受天气状况而变，且具有季节性、周期性的变化。一年中月平均海平面的最大值与最小值之差，称为年较差。例如渤海的月平均海平面的年较差为60～70厘米，黄海为35～50厘米，东海为30～35厘米，南海为20～40厘米，而恒河口可达170厘米 ，太平洋的檀香山仅约8厘米。年平均海平面的差异，可达10厘米左右。 1956年 ，中华人民共和国规定以青岛验潮站的多年平均海平面为中国统一的高程起算面，称为青岛平均海平面或黄海基准面。中国出版的地图上的海拔高度都由这个基准面起算。至于航海图上的深度，则从海图的基准面向下计算。 |
