Greenland meltwater lakes

After Tuesday’s brilliant lecture about Greenland’s meltwater lakes, I found these images taken in 2012 on a flight between Ilullisat and Kangerlussuaq, on the west coast, so about 68° N. The big problem with photos like these is that it is impossible to work out the scale.

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.

UNESCO Earth Sciences Lectures

Earth Materials for a Sustainable and Thriving Society

Minerals and other Earth materials are a key component in the development of a sustainable global society, providing essential raw materials for technologies and economic growth while respecting the natural world.

This Lecture Series, sponsored by UNESCO, has been organised in collaboration with IUGS and iCRAG. The Series will boost knowledge of Earth materials and lectures will be delivered in webinar format by recognized global experts. Presentations will be framed in the context of the United Nations Sustainable Development Goals.

Lectures will be freely accessible, and recordings will be made available online soon after presentation. To book a place visit:

Wirral Geology and Landscape project.

As you might know this is a joint project involving members of the LGS and the University of Liverpool. Before lockdown we had a very successful day at the Heritage Fair at Birkenhead Town Hall. Several local talks were also given.
We have now established a mailing list for a wide range of people with interests in understanding the role of geology and geomorphology on the history and heritage of the area. We will shortly be launching an online noticeboard with ‘postcards’ pointing people at resources and hopefully developing displays that can be used at local scenic sites. We have already recruited a few new LGS members through this project,
All LGS members are welcome to join in – to participate or just get emails. Please email to start with. Future messages will be sent (Bcc) via

Request for help from U3A Heswall

Heswall U3A have 40 or more people waiting for the end of lockdown, so that they can set up a geology group Please would any LGS members who feel they could help out by offering basic topics or field trips, get in touch.
You don’t need to be a professional geologist . If you have time and enthusiasm to share let us know to and please give him permission to pass on your details to the local course organisers.
