Geoff Tanner Remembered

By SGA Member Dr Bruce Mair

With input from Alexandra Tataran, Archivist and Records Officer, British Antarctic Survey

It is with regret that I report on the passing of Peter William Geoffrey (Geoff) Tanner earlier this year. He played a significant role in completing the geological mapping of South Georgia in the 1970s.

Read more: Geoff Tanner Remembered

Geoff was a graduate of Sheffield University in the 1960s and moved to Imperial College London to work on his doctorate. His thesis, entitled “Structural and Metamorphic history of the Kinloch Hourn area, Inverness-shire” was submitted in 1965, and established his specialisation in structural geology. Thereafter, at the University of Leeds, he worked on the Precambrian of Connemara, and in the early 1970s on the structural setting of ore bodies in the Rwenzori of Uganda. Complex geology in complex field areas!

He joined the British Antarctic Survey (BAS) in 1973 as a Principal Scientific Officer (PSO) with the Earth Sciences Unit (Birmingham University) and in 1976 transferred to Earth Science Division (BAS Cambridge). He was responsible for coordinating the final geological mapping programmes of South Georgia, and management of BAS geologists tasked previously to do so, both in the United Kingdom and in the field.

He conducted field work from King Edward Point (Base M), and along the southwestern coastline during the 1973-74 and 1975-76 austral summers respectively. His team of geologists included Roger Clayton, David Macdonald, Bruce Mair, Rory Mortimore, Tim Pettigrew, Phil Stone and Bryan Storey. Under Geoff’s leadership, their field work and research, was published in a series of BAS Scientific Reports, BAS Bulletins and external geological publications. Geoff and his team finally completed the first comprehensive geological mapping of South Georgia, established the ages of the various stratigraphic and lithological units, and placed South Georgia in its regional context within the Scotia Arc and in relationship to the Antarctic Peninsula and the Southern Andes.

Geoff left BAS in 1979 and joined the Geology Department of Glasgow University, and subsequently became an Honorary Research Fellow in 1990. He suffered from Parkinson’s Disease in later life but nevertheless maintained his formidable reputation as an authority on the structural geology of the Scottish Highlands. In recognition, he was awarded the Clough Medal by the Edinburgh Geological Society in 2008. Geoff leaves his wife, Judith, a daughter and a son.

For a photo of Geoff see the official obituary on the Geological Society website:

Geoff is commemorated on the map of South Georgia by Tanner Island. The APC Gazetteer states “It is the largest and westernmost of Pickersgill Islands, rising to 145 m, [and] was named after Peter William Geoffrey Tanner (b. 1938), BAS geologist, who worked on the island, 1975-76 (APC, 1979, p. 3).

SGHT Crow’s Nest Return Event, 7 September 2023

Please join the South Georgia Heritage Trust (SGHT) for an event at All Hallows by the Tower in London (the oldest church in the City of London AD675) to mark the safe return of Sir Ernest Shackleton’s Quest crow’s nest. After tens of thousands of miles travelled, and featuring in exhibitions in Athy, Ireland and Grytviken, South Georgia, the crow’s nest returns to its home in the crypt of All Hallows by the Tower Church.

The event will begin with a drinks reception and optional tours of the church. There will then be a series of speakers connecting the histories of Shackleton, South Georgia island, All Hallows by the Tower and the City of London. An insight into current South Georgia projects to preserve the island’s rich polar heritage and protect its unique wildlife and marine environment will also be shared. The event will conclude with a short liturgy and music from the Square Mile Choral Scholars.

SGA Initiative Fund Award to Shackleton Stage Project

This year the Association has awarded a grant to James Burke and colleagues for a project entitled ‘Beyond South Georgia’ the aims of which are the production of marketing materials to promote the story of Shackleton’s incredible journey from Antarctica to South Georgia and the subsequent rescue of his expedition from Elephant Island. The ultimate aim is to bring this story, and the people and the environments in it, to the stage.

The project will involve a series of workshops to experiment with applying sound and movement to a text in order to generate the artistic ideas to captivate audiences from the stage. Using a videographer to film the workshops, a stage designer to create concept art and a graphic designer to knit it into a cohesive marketing image for moving towards a full stage production. The South Georgia Association is very proud to support such an unusual and worthwhile project.
