New citizen science project

This project, launched on 12th January 2021, is inviting the public to help recover data from historic tide gauge ledgers from the North West of England and convert it into usable data by scientists.

The National Oceanography Centre’s (NOC) Permanent Service for Mean Sea Level (PSMSL) dataset is used globally to study climate change and sea level rise by many organisations including the Intergovernmental Panel on Climate Change (IPCC).

NOC’s Head of PSMSL and Marine Data Manager, Elizabeth Bradshaw, is coordinating the project, and commented “Around 3 million people live near the coast in the UK, and with global sea level rising, we need long records to be able to investigate how local tides and sea level are changing. One way this can be done is by recovering data from old documents. In this project, we are trying to convert data from old tide gauge ledgers from two locations in the North West of England into data usable by scientists.”

The first ledgers, comprising of around 16000 pages, focus on two locations: George’s Pier in Liverpool, now the site of the Cunard Building, and Hilbre Island, a tidal island on the Wirral peninsula.
