GeoPolicy: What’s new in 2022?

Chloe Hill January 7, 2022

2021 was yet another year of uncertainty, with many changes and disruptions to our plans, activities, and goals. EGU’s science for policy programme was no exception to this with the Science for Policy Pairing Scheme and annual Science for Policy Event taking a back seat. We hope that 2022 will not only bring new activities but also rekindle those that were put on hold as a result of the pandemic. ...[Read More]

Climate Change & the Cryosphere: Fjord sediments reveal how melting ice impact the marine ecosystem

Mimmi Oksman and Anna Bang Kvorning January 7, 2022

It is scary how fast the Greenland Ice Sheet is melting and how much freshwater it is discharging to the coastal areas around Greenland. This freshening is having a serious impact to coastal marine primary production, which is the foundation of the Arctic marine food web. Now, because of increased melting and freshwater discharge, we need to understand how coastal ecosystems will react. How will A ...[Read More]

Imaggeo On Monday: Geometric Microscape of Agate

Bernardo Cesare January 3, 2022

“Crazy Lace” is an agate collected in Mexico, which offers great opportunities for aesthetic photomicrography. Here we see the common arrangement of fibers of chalcedony (microcrystalline quartz) in parallel bands alternating with black thin layers of Fe oxides. Polarized light photomicrograph, crossed polarizers and red tint plate. width 5.4 mm. Sample kindly provided by Denise M. Har ...[Read More]

Psychology in outcrop studies: heuristic biases – our ‘best’ enemies?

Ramon Lopez December 30, 2021

There are not many scientific publications that tackle the issue of subjectivity in geological studies and its impact. In one of them, Baddeley et al. (2004), they state it clearly in some sentences: “the judgements of experts can be biased by their use of heuristics to guide the formation of their opinions” or “accepted or prior opinions of existing experts certainly affect the judgement of other ...[Read More]

Imaggeo On Monday: A meander in the meltwater valley

Julien Seguinot December 27, 2021

At the edge of the Greenland Ice Sheet, surface melt releases old layers of dust, that have travelled thousands of years into the ice. Under sunny weather, the dust heats up with radiation, melts the ice underneath, and thus accumulates in tiny potholes and meltwater creeks. However, this photo was taken after a rainy day. The rain triggered increased melt on the surface of the ice irrelevant of i ...[Read More]

Additional teaching tips

Menno Fraters December 22, 2021

In June 2020 I made (my first!) blog post for the EGU blog on the topic of teaching, describing what I learned by for the first time teaching a full class on my own. It was at the time when teaching suddenly had to shift from in person to online teaching. Last quarter I was teaching again, but now the situation was the reverse. We had to move from online teaching back to in person teaching. In thi ...[Read More]
