Marion Island and Prince Edward Island (collectively the ‘Prince Edward Islands’) are two small sub-Antarctic islands situated in the Indian sector of the vast Southern Ocean. These protected islands belong to South Africa and are managed as ‘special nature reserves’. Like a number of prominent South African scientists, Brian Huntley spent a substantial amount of time on these islands as a young researcher – one distinction being that he was one of the very first to visit these islands with the explicit mission of undertaking field research. Exploring a sub-Antarctic wilderness is a collection of his diary entries on the islands while he spent 15 months there as a recent graduate and as part of the First Biological and Geological Expedition to the islands in 1965/1966. This expedition was the brainchild of Professor E.M. van Zinderen Bakker Snr, a scientist working for the University of the Orange Free State (currently University of the Free State) in South Africa. He also later compiled a monograph (van Zinderen Bakker, Winterbottom, & Dyer, Reference van Zinderen Bakker, Winterbottom and Dyer1971), which included most of Huntley's work undertaken during his stay on the islands – Exploring a sub-Antarctic wilderness is appropriately dedicated to him.

The book is an enjoyable blend of diary entries, original photographs of the islands, expeditioners and animals, and even a few handy illustrations of data recorded during the expedition. It is structured in a way that clumps diary entries that fit into specific themes and sub-themes together (chronologically within these). This can be quite bewildering at times, since the reader effectively skips back and forth in time throughout the book, precluding a real appreciation of the temporal sequence of events and (perhaps subtle) changes in the perspective and mind-set of the author. It also leads to some, although limited, duplication of diary entries relevant to multiple themes. However, the grouping of themes does perhaps allow for a better understanding of the topics themselves and further gives the reader freedom to read only small sections at a time.

The first broad theme is an introductory one, focussing on the preparation period and early times on the island. Team recruitment and training was a remarkably simple process involving very little real preparation of the team members for the conditions they were to face. Perhaps inevitably, Huntley and the rest of the team had to learn for themselves in situ about the dangers and discomforts of undertaking research in the harsh sub-Antarctic. A case in point are the few diary entries detailing the events around the overnight disappearance of one of their team mates (Neville Fuller) after being separated from the rest of their hiking party in very strong wind conditions:

This is followed by a theme entitled Fieldwork before the age of field huts, which provides one with a glimpse of what it meant to do fieldwork in the perennially wet, windy and cold conditions of the islands without much of the modern-day amenities now available. The mention of field huts in the title here refers to the now very well-stocked field huts present on Marion Island at various strategic locations, making it possible for field researchers to traverse the island without having to carry tents and food. It is truly impressive to read here, and in later sections, how much time the author and colleagues spent in the field given that they had to be completely self-sufficient, carrying very heavy (approx. 40 kg) backpacks along as they went.

The third theme is entitled Teamwork on a remote island, which includes diary entries that epitomise the sometimes fun and sometimes less-fun aspects of living with a very small group of people as exclusive company in a remote place for a long time. It is striking how the author's descriptions of other team members remain remarkably positive and diplomatic throughout – perhaps the most critical entry being in regard to a team member upset with the author's experiments affecting the power supply to the station. Huntley simply concludes with:

These entries speak volumes of the evidently very affable, and mature, nature of the author.

Getting down to the research programme is the fourth major theme and features entries relevant to a wide array of investigations that the author either led or contributed to. This section makes up the single largest theme of the book and is filled with diary entries detailing the work undertaken on aspects as diverse as the geological origin of the islands to extensive work undertaken on the plant communities and even observations of the seabirds and seal populations. The breadth and detail of the entries here display the author's inspiring enthusiasm and yet remarkable maturity of understanding. As the botanist on the team, Huntley's diary entries include details on a variety of botanical surveys and experiments he undertook, ranging from the discovery of new plant inhabitants (four previously unrecorded indigenous species and nine introduced species), the description of vegetation complexes, through to studies of plant phenology and altitudinal zonation. Much of this work has proved invaluable to more recent work assessing how vegetation communities on Marion Island have responded to climate change (for example, le Roux & McGeoch, Reference le Roux and McGeoch2008). It is obviously a great pity that the author notes that the ultimate fate of many of his collections (including more than 1,500 herbarium samples) are unknown following their return to mainland South Africa.

The two visits that the author made to Prince Edward Island (the smaller of the two islands on the archipelago) are afforded a separate theme, entitled The jewel in the crown – Prince Edward Island. Having no permanent structure on the island and having never been surveyed or explored as part of a scientific expedition, these two sorties stand out as really special experiences for the author. The relatively pristine Prince Edward Island is still today only visited irregularly (roughly once every five years) as part of scientific expeditions, maintaining its extraordinary status as one of the least known and unspoilt pieces of land anywhere on the globe.

The book concludes with a Postscript and Annexes, which provide a short overview of how the research programmes (run through the South African National Antarctic Programme) and management plan of the islands have evolved during the past six decades or so.

Each theme and sub-theme is introduced by a short section providing some background to the topic covered in the subsequent section. These are generally very useful, providing relevant context to the diary entries that follow, particularly by introducing the people mentioned later on. They also often offer some interesting bits of historical information on topics such as the early understanding of the geology of the islands, origin of its fauna and flora, as well as human impacts on the islands. I found some of these bits of trivia to be superfluous (for example, we are reminded more than once about the advent of the internet), although this is probably personal preference. While there are very few errors, spelling or otherwise, in the book, I could not help but notice the niggling erroneous description of the location of the islands as being ‘some 1400 km southwest of the southern tip of Africa’. The islands are actually situated approximately 2000 km southeast of the southernmost point of Africa. This error would not have been so conspicuous had it not been printed on the cover flap!

All in all Exploring a sub-Antarctic wilderness is a testimony to the inquisitive nature of the author and the seemingly endless enthusiasm and drive he must have had to continue working so hard, taking breaks very rarely (such as for Christmas celebrations). And this as a 20-year-old without any direct supervision! The book provides a good viewpoint on what it meant to do field science in the 1960s before the dawn of the current metric-driven, super competitive scientific era. It will obviously be of interest to more recent visitors to Marion Island and unsurprisingly contains a few ‘South Africanisms’ (which are perhaps tricky for others to follow). However, I can happily recommend it to anyone with an interest in the early days of ‘modern’ scientific work in remote places, particularly the sub-Antarctic.
