从利物浦，英格兰西北部的高水潮汐信息的“数据考古学”的练习，导致在建设的时间序列的“调整后的平均高水”跨越1768年到现在，可以被用作代理平均海平面（MSL）的记录。这个时间序列虽然不完整，但可以说是世界上第二古老的海平面相关记录，仅次于阿姆斯特丹的（1682年，尽管我们掌握的数据仅从1700年开始），与斯德哥尔摩的（1774年）相当。它描述了直到1880年的长期趋势为0.39+/−0.17毫米/年，20世纪的趋势为1.22 +/−0.25毫米/年，整体低频加速度为0.33+/−0.10毫米/年/世纪。当与该地区的地质海平面信息一起考虑时，证据表明，与从地质信息得出的长期预测相比，20世纪世纪海平面的长期趋势更大，主要是上个世纪下半叶加速的结果，与以前对极少数其他欧洲长期MSL记录的分析推断的结论一致。
An exercise of ‘data archaeology’ of high water tidal information from Liverpool, NW England has resulted in the construction of a time series of ‘Adjusted Mean High Water’ spanning 1768 to the present which can be employed as a record of proxy Mean Sea Level (MSL). The time series, although gappy, is arguably the second oldest sea level‐related record in the world, after Amsterdam's (1682, although the data we hold are from 1700 only) and of comparable age to Stockholm's (1774). It describes a secular trend for the period up to 1880 of 0.39+/−0.17 mm/year, a trend for the twentieth century of 1.22plus;/−0.25 mm/year, and an overall low frequency acceleration of 0.33+/−0.10 mm/year/century. When considered alongside geological sea level information from the area, the evidence suggests that the greater secular trend of sea level in the twentieth century, compared to long term projections derived from geological information, is primarily the result of an acceleration towards the second half of the last century, consistent with conclusions inferred from previous analyses of the very small number of other long European MSL records.
