In 1962 another scientist called Hess made a further discovery. The coastal structure proves that the Mid-Atlantic Ridge is home to newer rocks and the older rocks are closer to the USA. From this he concluded that the sea floor was slowly moving outwards from the Mid Atlantic Ridge, and moving towards the USA coast. The sea floor was spreading out from the middle, by up to 5cm every year!
Habitats:Corals were observed on most sites inspected from depths around 800 m down to around 2600 m. Octocorals dominated the coral fauna which comprised a total number of 30 taxa. The coral diversity was higher in the southern area compared with the northern. Live reef structures are main habitats in the mid-atlantic ridge.
