The Bottom Temperature of Snow cover (BTS) is defined as the temperature measured at the snow/ground interface (Haeberli 1973). This is different to Ground Surface Temperature (GST), which is measured in the ground (soil or rock) slightly below the surface. … Continue reading →

My former colleague Ben Marzeion (now at Bremen University) developed a simple way to calculate the changes in glaciers using only air temperature and precipitation as inputs. What is critical to a glacier is how much snowfall it gets per … Continue reading →

Recently, well, ok now that I get round to posting this, not so recently, as this happened at the end of last year …. we found a mistake in one of papers: Collier, E., Nicholson, L. I., Brock, B. W., … Continue reading →

Since the launch of Mariner 9 in 1071 we have been getting better and better images and information about Mars, from improved satellite imagery, radar and ground sampling from the amazing Mars rovers. We now know that both water and … Continue reading →

In 2016, the World Glacier Monitoring Service (WGMS) celebrated its 30 year existence, although some of the data series held by the WGMS extends much further back in time. In 1986, two former ICSI (now IACS: International Association of Cryospheric … Continue reading →

The research project ‘Calving rates and impact on sea level’ (CRIOS) has kept a number of my colleagues in Svalbard and elsewhere busy over recent years. Penny How, a PhD student at Edinburgh University is a bit of a pro-star at … Continue reading →

In June 2016, a team of scientists visiting the Khumbu region observed a flood near Chukhung. Rare footage of floodwaters exiting the nearby Lhotse glacier and flowing towards Chukung on 12 June 2016, was recorded by Elisabeth Byers, and now … Continue reading →

Dr Mauri Pelto has a great blog called From a Glacier’s Perspective in which twice a week he posts case studies of glacier change observed from freely available satellite data. Its a great tour of the worlds glaciers and an … Continue reading →

One challenge in science is framing quantities that we are used to dealing with in a way that people who are not used to dealing with them can understand. For global glaciology the challenge is in explaining mass changes from … Continue reading →

On 11 February it was International Day of Women and Girls in Science. Which is a UN Event apparently. To be honest my usual way of tackling gender imbalance in science is just to try and get on with being … Continue reading →
