New landmass has been unearthed under the frozen waters of the Davis Strait.
This strait is the narrow ocean channel between Baffin Island in Canada and Greenland.
The newly identified featureis now called the Davis Strait proto microcontinent.
It is made up of abnormally thick continental crust and is about 12 to 15 miles (about 19 to 24 kilometres) wide.
The Microcontinents are pieces of continental crust that have separated from extended landmasses but did not completely detach in major tectonic episodes.
For this proto-microcontinent, it seems to have remained partially attached when Greenland and North America rifted.
