The Challenger expedition departed from Portsmouth, England and this map shows the route of the first part of the journey. Along the way the crew were engaged in dredging, trawling and sounding operations. Challenger visited Lisbon, Gibraltar, the West Indies, Nova Scotia, Brazil, Tristan da Cunha, South Africa, Antarctica, Australia, New Zealand, the Pacific and Marianas Islands, Japan, Hawaii, Chile and Tierra del Fuego. While in the Marianas region in early 1875, the Challenger crew sounded the Mariana Trench; the first people to do so. They recorded a depth of just over eight kilometres. The trench, in the Pacific Ocean, is the deepest the world over.
