The Global Extreme Sea Level Analysis (GESLA) Version 3 dataset: Part 2.

This dataset is a major update to the quasi-global, high-frequency (at least hourly) sea level dataset known as GESLA (Global Extreme Sea Level Analysis). Versions 1 (released 2009) and 2 (released 2016) of the dataset has been used in many published studies, across a wide range of oceanographic and coastal engineering-related investigations concerned with evaluating tides, storm surges, extreme sea levels and other oceanographic processes. The third version of the dataset (released 2021), presented here, contains twice the number of station-years of data (91021), and nearly four times the number of station records (5119), compared to version 2. The dataset consists of records obtained from 36 sources around the world, including some data archaeology efforts. The oldest record dates from year 1805 (spanning 217 years), followed by a few other stations starting during the 1840s and 1850s. However, the vast majority of records start during the 1950s. Data have been updated until mid-2021 whenever possible. We have archived the dataset into two parts. This second part contains the 592 records that are can be used for research purposes, but not consultancy. The higher-frequency sea-level dataset in this second part of GESLA-3 was obtained from 3 international and national data providers, specifically: City of Venice, Tide Forecasts and Reporting Center, University of Zagreb and the Copernicus Marine Environment Monitoring Service.
