MOSAiC Leg 3 This year, things seem to happen differently. It is true, globally, for all the changes induced by the corona pandemic. And it was also true for our leg 3 of MOSAiC, where moods of nature and covid-19 created confounding effects… Before leaving for the field study in […]

You know those days when nothing goes as you though it would? You have a plan and then life happens and everything gets thrown out of the window, but somehow you make a comeback and it turns out to be a great day? I had one of these days on […]

The dramatic mountains and glaciers of the Himalayas draw visitors from around the world.  ‘Himalaya’ means ‘the abode of snows’, yet many of the region’s visitors may not realize that these glaciers are themselves composed of snow, slowly transformed over time into ice. Although the compaction, metamorphism and densification of […]

The Laboratory of Hydraulics, Hydrology and Glaciology received funding from the SPI to perform fieldwork in summer 2019 on Bowdoin Glacier, an outlet glacier of the Greenland icesheet. This glacier is quite special, because despite its high flow velocity (up to 2m/day where the glacier ends in the sea), it […]

End of the campaign Last Saturday I packed the W-band Doppler radar (WProf), which has been measuring clouds and snowfall above Princess Elisabeth Antarctica base since early December. All the rest of the equipment was already dismounted in the previous days and stored in the base, so this moment assumes […]

Together with Alfonso Ferrone, PhD student at Environmental Remote Sensing Laboratory LTE, we arrived in Antarctica at Princess Elisabeth Station on 22 November. We have been since then busy deploying a variety of instruments to monitor clouds and precipitation, with of course many expected and unexpected issues. The SPI Exploratory […]

With the research vessel Polarstern moored to a suitable ice floe, SLF researcher David Wagner and his colleagues start to explore their surroundings and install measuring instruments. Things rarely go entirely to plan, with visiting polar bears and abrupt ice shifts complicating the work. After arriving at ‘our’ flow, we […]

What’s in an ice core? That seems like an odd question. But essentially, that is what we are trying to figure out. We use climate records from ice cores all the time to learn about the past climate and its variability and they are amongst the most important contributors to […]

Measuring glacial movements in-situ is a challenging, but necessary task to model glaciers and predict their future evolution. However, installing GPS stations on ice can be dangerous and expensive when not impossible in the presence of large crevasses. In this project, the ETHZ Autonomous Systems Laboratory develops UAVs for dropping […]
