There's a huge hole that extends over thousands of square miles in the Atlantic seafloor between the Cape Verdes Islands and the Caribbean nearly 2 miles below the ocean surface where Earth's deep interior is exposed without any crust covering and a team of scientists wants to find out why.
"It's quite a substantial area," said Chris MacLeod, a marine geologist at Cardiff University in the UK, who will be part of the expedition.

SALT LAKE CITY -- A 17-year U.S. study shows the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than thought.
At least 40 people have been killed and scores more are missing in landslides on the Indonesian island of Flores, officials have said.
The Mont Blanc tunnel connecting France and Italy has been closed to traffic due to a landslide on the French side, the ATMB company which jointly runs the tunnel said on Saturday.
Experts were on site to decide on how to clear the blockage but the company said the 11.6 km (7 mile) tunnel beneath western Europe's highest mountain was unlikely to be reopened to traffic before the end of the day.
On THE morning of December 26, 2004, villagers from Bang Koey in Thailand noticed something strange. Buffalo grazing on the beach lifted their heads, pricked their ears and looked out to sea, then stampeded to the top of a nearby hill. For the baffled villagers who chose to follow them, it was a live-saving move. Minutes later, the tsunami struck.
Since then, there have been hundreds of reports of animals seemingly foretelling catastrophe - not just minutes, but sometimes hours and even days before it occurred. These include tales of bizarre behaviour by wild beasts including elephants, antelopes, bats, rats and flamingos, plus stories of dogs refusing to go for their usual morning walk.
Could these creatures have sensed the massive earthquake that triggered the 2004 tsunami? It is an outlandish assertion, given that seismologists have so far failed to come up with any sign that a quake is imminent. Yet, for the same reason, the possibility animals might hold the answer cannot be ignored. After all, an advance warning system could save thousands or even millions of human lives.
The unseasonably warm weather this winter has set records in the Tohoku region, hurting business at ski resorts but helping other industries.
The warmth has also led to bigger hauls of fish, especially anchovies, with the December catch of the species 45 times larger than usual.
In Iwate Prefecture, 21 of the 34 meteorological observation posts--including those in Morioka, Ofunato and Miyako--did not record a single day below 0 C between December and the end of February. In Morioka, temperatures stayed above freezing through the end of February for the first time since records were first kept there in 1924. In Hachinohe, Aomori Prefecture, it was the first time that temperatures had stayed so high since the city began keeping records in 1937.
In Maebashi, meanwhile, it was the first time since records began being kept there in 1897 that snow did not accumulate.
A major clean-up operation is under way in several states in America's south and mid-west after tornadoes and storms left at least 20 dead.
Hardest hit was Alabama, where at least eight people died when a tornado struck a high school building on Thursday. Nine more people died in Georgia.
US President George W Bush is due to visit some affected areas on Saturday.
The tornadoes were part of a major storm system that stretched across a swathe of the United States.
Scientists probing the Earth's interior have found a large reservoir of water equal to the volume of the Arctic Ocean beneath eastern Asia.

UNITED NATIONS - UN Secretary General Ban Ki-moon said on Thursday that global warming posed the same threat to humanity as war and warned of an "unconscionable legacy" being left for future generations.
In a speech to a UN International School Conference, Ban acknowledged that the "majority" of the UN's work still focuses on the prevention and resolution of conflict.
"But the danger posed by war to all of humanity -- and to our planet -- is at least matched by the climate crisis and global warming," he said.
Canberra was last night bracing for a second major storm as it cleaned up from Tuesday night's damaging "supercell" storm, which dropped up to 1m of hail and caused chaos in the centre of the capital.
Hailstones as large as golf balls and winds over 50kmh lashed the city for less than 30 minutes on Tuesday night but left trees defoliated and turned nature strips into mud baths.
