Asked by Rose Hello, I came upon ur topics about Ice velocity, I have a question regarding it. So what would be the difference between the ice velocity of Glacier during summer and winter? considering the velocity for the top and bottom of the glacier? am I correct that summer would be faster and basal […]

Asked by Yve Question:Hi Bethan,I work as a natural history presenter on expeditions ships in Antarctica. I talk a lot about the ice but I am having difficulty finding answers to a couple of questions. Can you please help?In some parts of NW Antarctic Peninsula, the surface of many large glaciers draining the ice cap

I live in southern Wisconsin, USA, an area full of glaclal geology features.  Drumlins seem such an enigmatic glacial feature. Easily recognized, but seemingly a mystery of  how it is formed.  What is the latest thoughts on how drumlins were formed.  Are any noted from Antartica or Greenland? Asked by Daniel Many people think that

Asked by MessiHe A great question! When we look at most glaciers and ice sheets, the velocity is higher at the marine-terminating snout. So what is going on? There are several factors at play here. Firstly, if the glacier is floating at its terminus, then there is zero friction or basal drag to slow down

Question: regarding Thwaites:  I note that tectonic sources create warm water currents that are increasing the melt rate of the shelf and glacier, moving the grounding line inland. It seems that this is a “natural” occurrence, not related to climate change. If we are using Thwaites as an example of climate change, how do we

Hi John, Great question! A 2021 study on the Thwaites glacier by Wild et al. suggests that the Thwaites pinning point will detach from the sea bed and reach floatation within the next decade, which has some serious implications for the Eastern Ice Shelf, and in turn, the whole Thwaites Glacier. They suggest that the

Question:  I read somewhere that lead deposits from Roman times (approx 2,000 years ago) have been discovered in ice cores approx 400 metres below the current ice surface in Greenland. As a non-scientific person, I am asking a very basic question: if the above information is correct, then that suggests that around 400 metres of

Question: My name is Alexander Chladzynski, I am 11 and curious about many things. For a school project I am doing it on how Antarctica is melting. It would be awesome if you could give me some facts about Antarctica. Great question Alexander, the majority of ice melt in Antarctica is around the edges of

Question: I’m teaching A-level Glaciation, and we have to talk about Ice Sheets and the landforms that they create and the one that is talked about often is an Ellipsoidal Basins especially related to the Laurentide Ice Sheet and Minnesota . I was wondering if you have any diagrams or simple explanation to explain the
