Sea-level changes and crustal deformations at the southern Baltic Sea during the last 200 years

这项提议的目的是详细调查过去200年来波罗的海南部沿海的海平面变化。对于这一所谓的“仪器时期”，将绘制沿海平均海平面趋势和海平面极端情况的精确图景。主要数据来源是历史和最近的验潮仪数据和风暴潮基准。将对全球定位系统(GPS)卫星的历史水准以及重复和永久观测进行分析，以调查地壳垂直形变。获得的高度变化将与全球参照系有关，并将适用于芬诺斯坎迪亚地区的区域调查。高空间分辨率的最终结果(平均海平面变化、某一级别风暴潮的概率计量、新构造垂直地壳运动)是项目1.1、1.5、2.1和2.2的重要投入信息。它们还将有助于理解更长时间尺度上的过程，并验证/校准各自的模型。

The aim of this proposal is the detailed investigation of sea-level variations at the coast of the southern Baltic Sea for the last 200 years. For this so-called "instrumental period" a precise picture of mean sea-level trends and sea-level extremes along the coast will be developed. Main data sources are historical and recent tide gauge data and storm surge benchmarks. Historical levellings as well as repeated and permanent observations of satellites of the Global Positioning System (GPS) will be analyzed to investigate vertical crustal deformations. The obtained height changes will be related to a global reference frame and will be fitted to regional investigations in the Fennoscandian region. The final results (mean sea-level changes, probability measures for storm surges of a certain magnitude, neotectonic vertical crustal movements) with high spatial resolution represent important input information for projects 1.1, 1.5, 2.1 and 2.2. They will also help to understand processes on longer time scales and to validate/calibrate respective models.
