Scientists have discovered four underwater mountains — the tallest of which is more than 2.5 kilometres long — while travelling from Golfito in Costa Rica to Valparaiso in Chile on a research vessel, announced the Schmidt Ocean Institute
The mountains they discovered range in size from around 1,591 kilometres high to around 2,681 kilometres, which is more than three times the height of Burj Khalifa, the tallest building in the world. This adds to the same crew’s discovery of a 1,600-metre tall mountain off the coast of Guatemela last November.
“We were fortunate enough to be able to plan an opportunistic mapping route using these gravity anomalies in satellite altimetry data. Examining gravity anomalies is a fancy way of saying we looked for bumps on a map, and when we did, we located these very large seamounts while staying on schedule for our first science expedition in Chile at the start of this year,” said John Fulmer, one of the researchers, in a press statement.
Scientists from the Schmidt Ocean have used the research vessels Falkor and Falkor (too) have mapped about 1.5 million square kilometres and discovered 29 underwater mountains, hills and trenches. The latest discovery was made using Falkor (too). This work is important because underwater trenches often host deep-sea coral reefs, sponges and anemones that live alongside organisms that find food, shelter and a rocky surface to cling to.
