it s often said that we know more about the surface of the moon than we do about the ocean floor. only about a fifth of it has so far been mapped. this discovery is part of a larger mission to fill in those gaps in our ocean knowledge. and coral reefs like this are the sea floor hotspots for marine life. about a quarter of known ocean species can be found around these living ecosystems. the team is now planning more investigative dives to work out what lives here and, crucially, how their remarkable newly discovered habitat can be protected. victoria gill, bbc news. a 19 year old has become the youngest woman to fly solo around the world. zara rutherford has landed in belgium, at the end of herjourney which began in august last year. she flew across more than 50 countries on her own as jessica parker reports.
this is opening a new insight in science. this could suggest that we have many more large reefs in our ocean, at depths beyond 30 metres, which we simply do not know about. the depth of this reef means there is far less sunlight here than in the shallows. this part of the ocean is known as the twilight zone. there s stilljust enough light here for the algae that lives inside the bodies of the coral to survive and thrive. and critically, for the health of this reef, waters at these depths are not warming as quickly. it s often said we know more about the surface of the moon than we do about the ocean floor only about a fifth of it has so far been mapped, and coral reefs like this are the sea floor hotspots for marine life. about a quarter of known ocean species can be found around these living ecosystems. the team is now planning more investigative dives to work out exactly what lives here, and crucially, how their newly discovered remarkable habitat can be protected. victoria gill, b

from the coast is thought to be a key reason for its pristine condition. the researchers say it shows no signs of damage from pollution or from warming ocean temperatures, something that poses a major threat to swallower reefs. it looks beautiful but scientifically, how important is this as a discovery? it might be today one of the largest coral reefs in the world that actually lies at that sort of depth of more than 30 metres so from that perspective, this is opening a new insight in science. this could suggest that we have many more large reefs in our ocean at depths beyond 30 minutes which we simply do not know about. it is often said we know more about the surface of the moon than we do about the ocean floor. only about a fifth of it has so far been mapped. this discovery is part of a larger mission to fill in those gaps in our ocean knowledge. and coral reefs like this are the sea floor hotspots for marine life. about one quarter of known ocean
