Have you ever wondered what dark secrets the Arctic sea ice holds during the harsh winter months? Imagine total darkness in the central Arctic, making it almost impossible to gather scientific information. At this time of the year, usually only satellite observations are available. This changed in September 2019 when a team of scientists collected …[Read More]
The Caucasus is one of the most studied glacierized regions in the world (see previous Cryoblogs on Caucasus glaciers here and here). In this week’s blog, Levan Tielidze tells us about the health of the Greater Caucasus glaciers. His first study published this year indicates that the rate of decline in glacier extent between 2000 …[Read More]
Reduced and thinner sea ice makes Arctic waters increasingly appealing for shipping, fishing, tourism, and mineral exploration. However, with increased accessibility and more dynamic ice conditions comes a greater risk for ship crews to encounter sea ice and icebergs outside of their usual seasonal limits. To help them navigate, timely and reliable sea ice information …[Read More]

Three years have passed since sea-ice scientists from both climate modeling and remote sensing backgrounds met for an international workshop in Hamburg. The goal was to discuss how to further improve our understanding of sea ice and reduce uncertainties in climate models and observations (see this previous post). One suggestion was to work on observation …[Read More]
With over 198 000 glaciers in the world, you can always find a glacier that fits your mood or a given occasion. So why not for example celebrate the first Image of the Week of May with a picture of the aptly named May Glacier? May Glacier is in fact not named after the month, …[Read More]
On September 15th, 2018, at 18:02 local time, NASA launched its newest satellite – the second generation Ice, Cloud and land Elevation Satellite (ICESat-2). ICESat-2 only contains one instrument – a space laser that fires 10,000 pulses per second to Earth to measure elevation. Its primary purpose is for monitoring the ever changing cryosphere, so …[Read More]
Common images associated with climate change include sad baby polar bears, a small Arctic sea ice extent, retreating glaciers, and increasing severe weather. Though slightly less well-known, river ice is a hydrological system which is directly influenced by air temperature and the amount and type of precipitation, both of which are changing under a warming …[Read More]
On 22 March 2018, large amounts of Saharan dust were blown off the Libyan coast to be further deposited in the Mediterranean, turning the usually white snow-capped Mountains of Turkey, Romania and even Caucasus into Martian landscapes. As many people were struck by this peculiar color of the snow, they started documenting this event on …[Read More]
Mapping Earth’s most remote continent presents a number of unique challenges. Antarctic cartographers and scientists are using some of the most advanced mapping technologies available to get a clearer picture of the continent. We asked Brad Herried, a Cartographer and Web Developer at the Polar Geospatial Center at the University of Minnesota, a few questions …[Read More]
Our image of the week shows the area around the calving front of Petermann Glacier through the spring, summer, and autumn of 2016. Petermann Glacier, in northern Greenland, is one of the largest glaciers of the Greenland Ice Sheet. It terminates in the huge Petermann Fjord, more than 10 km wide, surrounded by 1000 m …[Read More]
