Mjølnir Impact Crater

Friday, 2. November 2007, 13:25:27

,

The 40-km-diameter Mjølnir Crater is one of the best-preserved marine impact craters on Earth. It became interpreted as an impact structure in 1993. The structure is located in the central Barents Sea at latitude 73° 48´N, longitude 29° 40´E below ice-free waters. it is formed by the impact of an asteroid about 142 million years ago.

Drilling of the Mjølnir Crater - in The Mjølnir Scientific Drilling Project - has increased and will further increase our understanding of marine impacts and impact-induced processes along with the post-impact development of the Arctic.

Hi,

I have just checked both links, and here they worked, so probably the problem was only temporary?

Thank you for your interest!
