Long-term series of reliable sea level (SL) data are essential for understanding the trends and causes of SL changes, for furthering knowledge about the effects of current climate change and for predicting future SL evolution. This study aims to extend the SL time series of measurements along the Israeli Mediterranean coastline by revisiting historical benchmarks (BM) along the Israeli coast, first determined by the British Survey of Palestine (SOP) at 1922 and later by the Survey of Israel (SOI) in 1995. By identifying and remeasuring the historical BM from Gaza to Imera (1922) and in Jaffa (1936), this study reconstructs the historical mean sea level (MSL), anchoring it to the present national height network, and extending the SL time series of equipped measurements along the Israeli coastline. Accordingly, the study provides long-term SL trends for the Levantine Basin. The long-term SL time series reveals an increasing trend in the 1920s, which moderates during the 1930s, a decreasing trend from the 1960s to the 1990s, and a rapid increasing trend in the 1990s. As a result, it can be deduced that the historical datum can reflect the historical MSL of its period, extend the long-term SL data and by that indicate for environmental changes. Based on long-term SL data (1956–2016) it can be determined that the MSL of Israel is 0.082 m relative to the 1995 Israeli datum.

重温从英国托管时期到现在(1922-2017 年)以色列的历史海平面升高

长期系列可靠的海平面 (SL) 数据对于了解 SL 变化的趋势和原因、进一步了解当前气候变化的影响以及预测未来的 SL 演变至关重要。本研究旨在通过重新审视以色列海岸沿线的历史基准 (BM) 来扩展沿以色列地中海海岸线的 SL 时间序列测量,该基准线首先由英国巴勒斯坦调查局 (SOP) 在 1922 年确定,后来由以色列调查局 (SOI) ) 于 1995 年。通过识别和重新测量从加沙到伊梅拉 (1922) 和在雅法 (1936) 的历史 BM,本研究重建了历史平均海平面 (MSL),将其锚定到目前的国家高度网络,并扩展了 SL沿以色列海岸线装备测量的时间序列。因此,该研究提供了黎凡特盆地的长期 SL 趋势。长期 SL 时间序列显示 1920 年代呈上升趋势,1930 年代趋缓,1960 年代至 1990 年代呈下降趋势,1990 年代呈快速上升趋势。因此,可以推论历史数据可以反映其时期的历史MSL,扩展长期SL数据,从而指示环境变化。根据长期 SL 数据(1956-2016)可以确定以色列的 MSL 相对于 1995 年的以色列基准为 0.082 m。可以推论,历史数据可以反映其时期的历史MSL,扩展长期SL数据,从而指示环境变化。根据长期 SL 数据(1956-2016)可以确定以色列的 MSL 相对于 1995 年的以色列基准为 0.082 m。可以推断,历史数据可以反映其时期的历史MSL,扩展长期SL数据,从而指示环境变化。根据长期 SL 数据(1956-2016),可以确定以色列的 MSL 相对于 1995 年的以色列基准为 0.082 m。
