 We humans are natural explorers. We can't help ourselves. Whether it's new worlds across treacherous landscapes or planets and galaxies beyond our imagination the unknown calls to us and we are driven to discover what's out there. But in all of our centuries of exploring we've barely scratched the surface of one of the most fascinating places in the universe. Our own ocean. It covers two-thirds of our planet yet since the dawn of time we've only explored five percent of it. Crushing pressures, extreme temperatures and all-consuming darkness make exploration nearly impossible. The ocean remains the greatest mystery on Earth. What's going on down there? What discoveries await us? What new and fascinating forms of life will we find? The $7 million Shell Ocean Discovery XPRIZE is a global competition challenging teams to push the boundaries of existing ocean technologies and create safer, faster and affordable ways of exploring the deep sea. This includes a $1 million bonus funded by NOAA for breakthroughs in chemical and biological sensors. By harnessing the power of autonomous underwater robotics teams will illuminate the deep with high-resolution mapping and advanced imaging systems on a scale never seen before. The answers to some of humanity's oldest questions or the cures to our most deadly diseases could be waiting to be discovered. Imagine a future in which our ocean is healthy, valued and understood. Be part of the discovery, form a team or follow the competition online. The Shell Ocean Discovery XPRIZE Getting to the bottom of our ocean. Find out more at oceandiscovery.xprize.org
