This image was taken during the Arctic Ocean 2016(AO16) expedition that ventured to the central regions of the Arctic Ocean, including the North Pole. It shows a pressure ridge, or ice ridge, as viewed from onboard the deck of the icebreaker Oden. It was quite striking that the ice ridge resembled an image of a spine – sea ice being a defining characteristic of the broader Arctic environment and b ...[Read More]

Take some ice, mix in some rock, snow and maybe a little mud and the result is a rock glacier. Unlike ice glaciers (the ones we are most familiar with), rock glaciers have very little ice at the surface. Looking at today’s featured image, you’d be forgiven for thinking the Morenas Coloradas rock glacier wasn’t a glacier at all. But appearances can be misleading; as Jan Blöthe (a researcher at the ...[Read More]

This month’s GeoRoundUp is a slight deviation from the norm. Instead of drawing inspiration from popular stories on our social media channels and unique or quirky research featured in the news, we’ve rounded up some of the stories which came out of researcher presented at our General Assembly (which took place last week in Vienna). The traditional format for the column will return in May! Major st ...[Read More]

In 2008 the NEEM Deep Ice Core Project was initiated by 14 partner countries in Northwestern Greenland (camp position 77.45°N 51.06°W) with the aim to drill from the very top of the Greenland ice cap to its base; obtaining ice from as far back as the last interglacial period- the Eemian – some 130,000 years old. At the start of the 2008 field season, the NEEM camp consisted of a single hea ...[Read More]
