deepest point on earth

Scientists of the BedMachine project have revealed the latest topographical map of Antarctica. BedMachine is a new map of the Antarctic ice sheet believed to be of high precision. In which researchers have found the deepest point on continental Earth.

Till now we know the lowest exposed point on land is the Dead Sea at 430.5 meters (1412 feet) below sea level. It is a majestic and mysterious looking lake of light turquoise waters with salt crystals jutting out of it, and golden-brown hills surrounding it.

But the lowest point on land goes even deeper, as revealed by the new BedMachine data. At about 3500 meters ( about 11500 feet) below sea-level, the world’s deepest canyon on land was found beneath Denman Glacier in East Antarctica.

As per the previous data, the canyon was believed to be shallow, but the new study has uncovered its real depth. This time researchers have calculated the real depth of the hidden canyon by calculating the amount of ice that filled it and the law of conservation of mass. Using radar data of moving ice in the 20 kilometers-wide Denman Glacier, the researchers found that the ice was descending to over 3,500m below sea level.

“Ultimately, BedMachine Antarctica presents a mixed picture: Ice streams in some areas are relatively well-protected by their underlying ground features, while others on retrograde beds are shown to be more at risk from potential marine ice sheet instability,” said Mathieu Morlighem of the California university, the report added. you had read this article in science blog of our website.
