  • Imaggeo On Monday: Križna jama
    by Peter Huber on January 24, 2022 at 11:45 am

    The Križna jama Cave on the east side of the periodic Cerknica Lake in Slovenia is an underground karstic cave primarily famous as a rich site of bones of the extinct cave bear, Ursus speleus. The eight kilometer long cave is full of stalagmites and stalactites (sometimes called drip-stone decorations) and also boasts 50 underground lakes […]

  • Congratulations to the winners of the EGU Best Blog Posts of 2021
    by Gillian D'Souza on January 21, 2022 at 11:45 am

    At EGU, we like to believe that a new year is more meaningful when we pause to look back at the year gone by – just a brief glimpse to appreciate all our good work and progress! 2021 was certainly an excellent year for our blogging network at EGU. Across the EGU’s official blog, GeoLog and division blogs we had so many inspiring, […]

  • Imaggeo On Monday: Quartz – sericite mylonite, Calamita, Elba
    by Samuele Papeschi on January 17, 2022 at 11:45 am

    Concomitant thrusting and magmatism resulted in the development of ductile mylonites in the Calamita Schists, part of the contact aureole of the Late Miocene Porto Azzurro pluton. This mylonite is made up of stretched and recrystallized quartz layers, interlayered with thin sericite-rich levels. Sericite resulted from the crushing of […]

  • The James Webb Telescope may forever alter our view of the universe
    by Gillian D'Souza on January 14, 2022 at 11:45 am

    Where is Webb? This seemingly simple question is quickly making its way into everyday conversation, and not just in scientific and astronomy circles. After a long 32-year wait, NASA officially launched the James Webb Telescope a couple of weeks ago on 25 December 2021. More recently, the telescope deployed its final primary mirror segment on 8 […]

  • What if a tsunami’s magnetic field could predict the height of the wave?
    by Gillian D'Souza on January 12, 2022 at 11:45 am

    It’s been well established that tsunamis generate magnetic fields as they move seawater (which is conductive unlike freshwater) through the Earth’s magnetic field. Although researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, they lacked the means to simultaneously measure […]

  • Imaggeo On Monday: Artificial peridotite takes its gold coat off
    by Thomas P. Ferrand on January 10, 2022 at 11:45 am

    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 […]

  • GeoPolicy: What’s new in 2022?
    by Chloe Hill on January 7, 2022 at 11:45 am

    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 […]

  • Imaggeo On Monday: Geometric Microscape of Agate
    by Bernardo Cesare on January 3, 2022 at 2:05 pm

    “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. […]

  • Imaggeo On Monday: A meander in the meltwater valley
    by Julien Seguinot on December 27, 2021 at 11:45 am

    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 […]

  • Imaggeo On Monday: Contorted Streams on the Gates Glacier
    by Allen Pope on December 20, 2021 at 11:45 am

    Annual ridges and troughs (called wave ogives) are formed as the ice of the Gates Glacier (in Alaska’s Wrangell Mountains) flows through a steep icefall. Down-glacier, as the ice melts, the rushing meltwater is funnelled into streams, carving ice canyons as it flows, but ultimately directed by these topographic constraints.   […]
