Jack Wilkin (UK) During April and May 2022, I had the fantastic opportunity to participate in a research expedition to the North Sea and Iceland on the RRS Discovery, as part of the SEACHANGE project. The following article is a brief description of the science that happened on the ship. What is the SEACHANGE Project? SEACHANGE is a six-year research project funded by the ERC Synergy Grant Scheme (part of the EU’s research and innovation programme, Horizon 2020). It is jointly run by the University of Exeter (UK), Johannes Gutenberg University Mainz (Germany) and the University of Copenhagen (Denmark). This is a collaborative project with scientists worldwide, from master’s students to professors working diligently to answer the question: What were the oceans like before large-scale human impact? To answer this question, we need to test the scale and rate of biodiversity loss resulting from fishing, whaling and habitat destruction over the last 2,000 years in the North Sea and around Iceland, eastern Australia and the Antarctic Peninsula. In addition, we need to find out more about the earlier transition from hunter-gatherer to farming communities in northern Europe around 6,000 years ago. However, before answering this question and starting to generate data, we first needed the raw materials. Because we were monitoring the oceans, we needed to go to the sea to gather our samples, so we need a boat … a very big boat. The RRS Discovery. The RRS Discovery (Fig. 1) is one of the most advanced research ships … Read More
I recently reviewed another of the guides in Crowood Press’s excellent “Landscape and Geology” guides, which was undoubtedly a great read. And this one is equally good, with great, full colour pictures, maps and diagrams, and easy to read text, with descriptions of interesting walks and what can be seen on them.That is, there are easy-to-understand explanations of how the rocks formed and how the geology affects the landscape, and there is also an n exploration of the long human story of the landscapes.
reviewed the 2nd edition of this guide a while ago and, as I said then, Iceland seems to set the hearts of certain geologists racing and, reading this field guide and that previous incarnation, it is abundantly clear why. Iceland’s fascinating geology is clearly set out in this concise and authoritative book. The island, astride the Mid-Atlantic Ridge, is a ‘natural laboratory’ where the earth sciences can be watched in real-time. Rifting of the crust, volcanic eruptions and glacial activity are among a host of processes and features that can be observed in this fascinating land.
As I said in my review of the first edition of this guide, I love geomorphology. In fact, I have loved it since my school days and deeply regret not having studied it at university. However, as I said in that review, I suspect many people are discouraged by its scientific name, but all it means is the study of the earth’s landforms and the processes that create the landscapes we see today.
I think the reason why this book is such a success is that River Planet not only introduces readers to the fascinating palaeo-history of the world’s rivers (both existing and disappeared), but also reveals the author’s personal account of his experience of rivers, together with a bit of history and interesting (and relevant) anecdotes, in the most entertaining of ways.
Dr Richard J Hubbard (UK) Introduction The Thanet Anticline is an uplifted area forming the northeast corner of Kent and is home to the four coastal towns of Birchington, Margate, Broadstairs and Ramsgate (Fig. 1). Historically, the area has been known as the Isle of Thanet and, in this article, … Read More

James O’Donoghue (UK) Did the destruction of forests by mammoths make the Pleistocene Ice Age even colder? It’s an extraordinary prospect. Yet, a leading fossil mammal expert thinks they did just that. Over many tens of thousands of years, mammoths and straight-tusked elephants ate their way through vast tracts of … Read More

Maybe it’s a result of my social anthropology and geological background, but I found this difficult but fascinating book a great read. It’s about nineteenth century India. It is not about the modern geological science or social anthropology of the subcontinent, but rather, the geological imagination of India, as well as its landscapes and people, and its history.

Jack Wilkin (UK) Palaeoclimatology is the study of past climates and environments using climate proxies, that is, the preserved physical characteristics of past, rather than using direct measurements of variables, such as temperature, levels of CO2 and so on. Many different types of proxies are used including, but not limited … Read More
If you can see past the somewhat robust title (a reference to James Hutton’s discomfort riding around Scotland on horseback during his geological investigations), this is an interesting read, combining both geological science and humour in just about the right measures.
Jan Willem van der Drift (The Netherlands) Historic finds In 1900, nobody knew what kind of tools man used before the handaxe. Some scholars assumed that early-man used ‘eoliths’ – handy natural forms. That theory turned out to be false. The earliest tools were manmade flakes and cores, and this … Read More
Robyn Molan (Australia) In an article in the Australian Age of Dinosaurs Journal (Issue 6, 2008) I dubbed the period between 1984 and 1994 ‘a decade of dedication’, thanks to the persistence of an American-Australian team headed by palaeontologists Tom Rich and his wife, Pat Vickers-Rich. (Tom wrote an article … Read More

Sea level change is something that probably everyone who does their best to keep up to date about climate change, thinks they know about and on which they will have an opinion.
