Global Average Absolute Sea Level Change

This dataset shows cumulative changes in sea level for the world’s oceans since 1880, based on a combination of long-term tide gauge measurements and recent satellite measurements. It also shows average absolute sea level change, which refers to the height of the ocean surface, regardless of whether nearby land is rising or falling.

本数据集展现了自1880年以来全球海洋海平面的累积变化，该变化基于长期潮汐观测数据与近期卫星测量的综合。此外，数据集还展示了平均绝对海平面变化，该指标关注海洋表面高度，无论邻近陆地是上升还是下降。
