South Georgia - major landscape change case study

South Georgia at risk... 

I've been following this story for the last few months. The huge iceberg called A68a which broke off the Larsen C Ice Shelf in 2017 has been drifting northwards since then. 

It is now being pushed by the Antarctic circumpolar current and is on a collision course with South Georgia. This would cause environmental catastrophe for the ecosystems, including a massive penguin colony and other activities including scientific work.

Full details are here in this excellent Reuters Graphic website resource, which includes some great images naturally. Notice the inclusion of Manhattan for scale on the image above. This is not going to be pushed out of the way...

If the berg lodges at the island’s flank, it could remain a fixture for up to 10 years before the ice melts or breaks away. That could block some of the island’s 2 million penguins – including King Penguins, Gentoos, Macaronis and Chinstraps – from reaching the waters to feed their young. The melting freshwater could also make the waters inhospitable for phytoplankton and other sea creatures that are crucial parts of the food chain.

A reminder that the resources that I wrote for the South Georgia Heritage Trust are now here, and can be used free of charge. Give them a go and let me know how you get on.

The iceberg is only around 50km away from South Georgia and collision seems inevitable, with the iceberg grounding itself close to the island and sitting there for a decade or more....

Ideal scenery

Check out this Robert MacFarlane tweet, and the replies that follow for a whole host of ideas on different people's ideal landscapes... Some wonderful images and brief descriptions ideal for sharing... "Tramlines and slagheaps, pieces of machinery, That was, and still is, my ideal scenery."

The path more travelled

I'm currently reading Nicholas Crane's new book on the history of Britain's footpaths: how they came about originally following the drowning of Doggerland , and were then refined by successive waves of change: horses, the Roman invasion etc. It's a dense and scholarly work, with plenty of points of interest and relevance to geographers exploring the connections between people and the landscape. He's taking his book on the road in a series of talks, with three confirmed so far. Here's the description for his talk at Stanford's book shop at the end of the month . He's also speaking in Exeter and Stamford. Walking is a cornerstone of British identity and the most popular form of exercise in the UK. But how much do we know about the paths that we walk? What is their history? Why do they follow the routes that they do? Are they permanent? Can we designate more of them?​ The Path More Travelled is a coast-to-coast history of footpaths from the stone age paths...

Glacier Melt Visualisation

This nice interactive infographic visualises the ice loss from Switzerland's glaciers. It is one of several from the VisQuill site , developed by Dr. Benjamin Niedermann.
