led scientific mission discovered it diving near the cents of the ocean known as the twilight zone. 100 to 200 feet below the surface where there s just enough light to sustain life. the coral reef appearing unaffected by climate change, stunning since warming waters have wiped out nearly half of the earth s known reefs and over the next couple of decades there will be a 90% decline according to the latest projections. it shows us still how little we know about our own planet and how important it is to gain more knowledge to better understand the processes of those oceans that will, again, influence life on our planet. reporter: norweigian oceanography everett is hoping to lead an international network of government, ocean scientists, industry and volunteers in a mission to map the world s sea bed by 2030. the shape of the sea bed and how deep it is and the ocean currents all influence toss a
their discovery underscoring how much we have yet to uncover in our ocean s depths. cnn s rene marsh has the story for us. reporter: here off the coast of tahiti, a stunning discovery. resting up to 230 feet below the surface was this, a huge untouched rose shaped coral reef nearly 2 miles long. researchers on a united nations led scientific mission discovered it diving near the depths of the ocean known as the twilight zone. 100 to more than 200 feet below the surface where there s just enough light to sustain life, that s where they found one of the world s largest coral reeves, appearing unaffected by climate change, stunning since warming waters have wiped out nearly half of the world s known reeves. and over the next couple of decades there will be a 90% decline according to the latest projections. it shows us still how little we know about our own planet and how important it is to gain more

i want my children to be able to see and experience the beauty of it. his passion is coral reeves. they re home to a quarter of all sea life. they re vital to global ecology, and they are dying. he is a lead instructor with the group diving with a purpose. what is your purpose? my purpose has morphed over time. at first the wreck-diver of 30 years joined dwp because the scuba group assembled mostly black divers to help look for a sunken slave ship. a watery tomb. spending so much time in the water, he noticed other mysteries. there are a lot less fish and there s a lot less coral. so he and his dive partner added an ecosystem monitoring program to the group s mission. they call it diving with a
