Geomythology. Hawaii islands and the journey of Pele

Hotspot Theory How would you explain a series of volcanoes in the middle of the ocean such as the Hawaii, the Midway or the Canary islands? J.T. Wilson, in 1963, suggested they are formed by relatively small, long-lasting, and exceptionally hot regions of magma located beneath the Earth crust, so-called “hotspots” (Wilson, 1963). Firstly, he applied this idea to the Hawaiian Islands, but the conce ...[Read More]

Imaggeo On Monday: Artificial peridotite takes its gold coat off

Sometimes in order to test a theory about how processes work below the surface of the Earth, scientists need to recreate minerals found in very specific circumstances. This photograph was taken through a binocular microscope during a critical step of the creation of artificial peridotite: extraction of the artificial peridotite from its gold capsule. The sample is a little cylinder, 3 mm long with ...[Read More]

Geoscience communication series: the perfect vlogging recipe

Last year, we left you with an inspiring post about scientific blogging, where Giulia Roder, one of the authors of the EGU-NH blog, shared her ‘blogging survival kit’. Today we continue the series of EGU WEBINARS: Digitalk: online (geo)science communication exploring ‘the best vlogging recipe’ with Iris van Zelst, a researcher at the German Aerospace Center with a great passion for geoscience comm ...[Read More]

GeoPolicy: What’s new in 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

Glacier debris ice floating in a bay

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

“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?

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

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]
