Exploring Our Oceans: The Challenger Expedition and Its Legacy
This exhibition has now closed. It ran from July to January 2023.
This free display of historic and contemporary images and specimens marks the 150th anniversary of the Challenger expedition - a ground-breaking scientific endeavour to sail around the world and systematically study the oceans for the very first time.
Until the Challenger expedition, the depths of the oceans were one of the great unknowns, having never been explored before. At the time, questions were being raised about whether life could even be sustained in their greatest depths. From 1872 to 1876, the Challenger expedition recorded data and collected thousands of specimens, fundamentally transforming our knowledge of the oceans.
Scientists both at the Museum and around the world continue to study the data and the specimens collected by the expedition 150 years ago. Using new techniques, they are gaining a deeper understanding of the impact that human activities and climate change are having on the ocean ecosystems we all rely on.
