由于（1）非气候、地质背景过程;（2）大气/海洋动力学;（3）冰和海洋质量再分布的重力、弹性和旋转“指纹”效应，局部海平面变化与全球平均海平面变化有很大不同。虽然研究这些不同影响的研究团体都有很长的历史，但将所有这些不同的过程整合到对过去变化的解释和对未来变化的预测中是一个活跃的研究领域。要充分描述这些过程过去的贡献，需要从涵盖一系列时间尺度的来源获得信息，包括地质代用指标、近三个世纪以来的验潮仪观测数据以及近二十年来的卫星测高数据。对当地海平面上升的预测必须考虑到不同过程的不同空间模式以及不同驱动因素之间的潜在相关性。
Local sea-level changes differ significantly from global-mean sea-level change as a result of (1) non-climatic, geological background processes; (2) atmosphere/ocean dynamics; and (3) the gravitational, elastic, and rotational "fingerprint" effects of ice and ocean mass redistribution. Though the research communities working on these different effects each have a long history, the integration of all these different processes into interpretations of past changes and projections of future change is an active area of research. Fully characterizing the past contributions of these processes requires information from sources covering a range of timescales, including geological proxies, tide-gauge observations from the last similar to 3 centuries, and satellite-altimetry data from the last similar to 2 decades. Local sea-level rise projections must account for the different spatial patterns of different processes, as well as potential correlations between different drivers.
