Jemma Wadham – författare

Longlisted for the Wainwright PrizeShortlisted for the Richard Jeffries AwardThe story of one woman's passion for glaciersAs one of the world's leading glaciologists, Professor Jemma Wadham has devoted her career to the glaciers that cover one-tenth of the Earth's land surface. Today, however, these 'ice rivers' are in peril. High up in the Alps, Andes and Himalaya, once-indomitable glaciers are retreating; in Antarctica, meanwhile, thinning ice sheets are releasing meltwater to sensitive marine foodwebs, and may be unlocking vast quantities of methane stored deep beneath them. The potential consequences for humanity are almost unfathomable.Jemma's first encounter with a glacier, as a student, sparked her love of these icy landscapes. There is nowhere on Earth she feels more alive. Whether abseiling down crevasses, skidooing across frozen fjords, exploring ice caverns, or dodging polar bears - for a glaciologist, it's all in a day's work.Prompted by an illness that took her to the brink of death and back, in Ice Rivers Jemma recalls twenty-five years of expeditions around the globe, revealing why the glaciers mean so much to her - and what they should mean to us. As she guides us from the Alps to the Andes, the importance of the ice to crucial ecosystems and human livelihoods becomes clear - our lives are entwined with these coldest places on the planet. This is a memoir like no other: an eye-witness account by a top scientist at the frontline of the climate crisis, and an impassioned love letter to the glaciers that are her obsession.

The Antarctic continent carries the greatest diversity of lake environments on the planet: freshwater and saline lakes, tidal freshwater epishelf lakes, lakes on ice shelves and glacier surfaces, and over three hundred subglacial lakes; extraordinary ecosystems that have been separated from the atmosphere for up to millions of years. This book provides a unique and cutting edge synthesis of Antarctic limnology, drawing together current knowledge on geomorphology, morphometry, chemistry, community structure and function. It emphasises throughout the value of these near-pristine ecosystems as barometers of climate change, showing how responsive and vulnerable they are to the indirect impacts of anthropogenic activity. Antarctic Lakes begins with an introduction to their physical, chemical, and biological characteristics, providing a basis for understanding the subsequent detailed chapters on different lake types, and ends with a chapter considering the application of new technologies to polar limnology as well as identifying future research directions. This accessible text is suitable for both senior undergraduate and graduate students taking courses in Antarctic and polar limnology, and will also be of broad interest to researchers working in the areas of polar science, microbial ecology (and extremophiles), climatology, glaciology, and astrobiology.
