Seismic Soundoff

In this episode, host Andrew Geary speaks with Les Denham on his new book, Blizzards and Broken Grousers: A Year of Antarctic Glaciology. Detailing one year of Antarctic field operations in 1970–71 acquiring ice thickness data with radar, gravity, and magnetometer measurements, this book depicts the pioneering spirit of geophysics in the time when field operations spanned the globe. Moreover, the data collected now underpin models of ice behavior used to assess climate change. Les offers a rare personal account of a scientific journey. This book (https://seg.org/shop/products/detail/237626086) provides a detailed account of the author’s Antarctic experience in a time before GPS, satellite communications, internet, and even links to Antarctica by air. In this conversation, Les shares the inspiration behind the book, his most memorable field trip in Antarctica, and how the technology he utilized in 1970 can help the geophysicists of today.
