By Catherine Brahic Yearning to re-enact 20,000 leagues beneath the sea, but a bit squeamish having tonnes of water above your head? Then dive into Ocean, the new upgrade to Google Earth. Thanks to space missions like the Mars Rovers, many people are more familiar with the landscape on other planets than with our own ocean floor. But Google’s new modelling tool may change that. To get you started, New Scientist has dredged up some of the oceans’ most exciting features you will want to put on your tour of the deep. Have a look at the mid-Atlantic ridge (Google Maps, Google Earth), Mariana trench (Google Maps, Google Earth) – the deepest point in the oceans – and the Pacific “ring of fire” (Google Maps, Google Earth). The hottest water found anywhere on Earth (outside laboratories, that is) comes spewing out of two black smokers called Two Boats and Sister Peak on the floor of the southern Atlantic. Their discovery helps explain how gold and other metals are drawn out of our planet’s entrails and deposited on the sea floor. (See Found: The hottest water on Earth) In 1995, researchers showed that the Indo-Australian plate, once thought to be a single slab of rock, had in fact split 8 million years ago. The two resulting plates now move independently of each other. Hydrothermal vents are key spots where minerals are brought up to the surface of tectonic plates from deep inside the planet. In 2006 a Canadian company announced its intention to mine dormant vents off the coast of Papua New Guinea, much to the dismay of marine ecologists. The project’s environmental assessment is underway. If granted, the project would be the world’s first seafloor copper and gold mine. The seascape around Hawaii is quite well studied, so the detail on Google Ocean should be good. One peak to look out for is Loihi (Google Maps, Google Earth), a submarine volcano which is slowly making its way to the surface. “We’re hoping to see how a Hawaiian island develops from womb to birth,” Alex Malahoff, director of the Hawaii Undersea Research Laboratory, Honolulu, told New Scientist. Research suggests the 1185 tourist-friendly Dalmatian islands could soon be more numerous yet as Italy inches towards Croatia, pushing the Adriatic seafloor up. On 9 August 2006, yachts sailing around Tonga reported sightings of a submarine volcanic eruption at Home Reef, south of Late Island. Three days later the crew of the Norwegian yacht Maiken caught sight of an island not found on any nautical chart. By mid-October,
