A journey through time and water, to the bottom of the ocean and the future of our planet. We do not see the ocean when we look at the water that blankets more than two thirds of our planet. We only see the entrance to it. Beyond that entrance is a world hostile to humans, yet critical to our survival. The first divers to enter that world held their breath and splashed beneath the surface, often clutching rocks to pull them down. Over centuries, they invented wooden diving bells, clumsy diving suits, and unwieldy contraptions in attempts to go deeper and stay longer. But each advance was fraught with danger, as the intruders had to survive the crushing weight of water, or the deadly physiological effects of breathing compressed air. The vertical odyssey continued when explorers squeezed into heavy steel balls dangling on cables, or slung beneath floats filled with flammable gasoline. Plunging into the narrow trenches between the tectonic plates of the Earth's crust, they eventually reached the bottom of the ocean in the same decade that men first walked on the moon. Today, as nations scramble to exploit the resources of the ocean floor, The Frontier Below recalls a story of human endeavour that took 2,000 years to travel seven miles, then investigates how we will explore the ocean in the future. Meticulously researched and drawing extensively on unpublished sources and personal interviews, The Frontier Below is the untold story of the pioneers who had the right stuff, but were forgotten because they went in the wrong direction.

The previously untold story of an extraordinary man and a great war photographer.Cameras were banned at the Western Front when the Anzacs arrived in 1916, prompting correspondent Charles Bean to argue continually for Australia to have a dedicated photographer. He was eventually assigned an enigmatic polar explorer - George Hubert Wilkins.Within weeks of arriving at the front, Wilkins' exploits were legendary. He did what no photographer had previously dared to do. He went 'over the top' with the troops and ran forward to photograph the actual fighting. He led soldiers into battle, captured German prisoners, was wounded repeatedly, and was twice awarded the Military Cross - all while he refused to carry a gun and armed himself only with a bulky glass-plate camera.Wilkins ultimately produced the most detailed and accurate collection of World War I photographs in the world, which is now held at the Australian War Memorial. After the war, Wilkins returned to exploring and, during the next 40 years, his life became shrouded in secrecy. His work at the Western Front was forgotten, and others claimed credit for his photographs.Throughout his life, Wilkins wrote detailed diaries and letters, but when he died in 1958 these documents were locked away. Jeff Maynard follows a trail of myth and misinformation to locate Wilkins' lost records and to reveal the remarkable, true story of Australia's greatest war photographer.
