Dept of Geography's Prof Christine Lane @chslane.bsky.social was at the Romanian Academy, Cluj, for the "Integrating ice core, marine & terrestrial environments" network meeting. The two-day event was a great success, with current and former @camtephra.bsky.social members presenting their research.

Last week PhD student @yqnatdeng.bsky.social and @chslane.bsky.social were sampling cores from an Ethiopian lake…in Aberystwyth! Here’s hoping there’s lots of ancient cryptotephra to be found!

LST floating in LST. Small pleasures 🤓🌋

the heavy liquid, lithium metatungstate)

A close up of a purple gloved hand in a lab, holding a transparent centrifuge tube, hand-labelled CT5015. The tube is approx 1/3 full with a clear liquid, floating at the top of which is a brownish cloud of fine particles. There is a dark residue at the very base of the tube, barely seen.

Volcanic ash originating from Russia’s Kamchatka Peninsula canceled Alaska Airlines flights to Nome and Kotzebue Tuesday morning.

The ash plume came from the Klyuchevskoy volcano, prompting an advisory from the Alaska Volcanic Ash Advisory Center.

Klyuchevskoy erupted shortly after a magnitude 8.8 earthquake two weeks ago.

Cambridge tephrochronologists discover Holocene wall art from the “other place”… 👀

Come visit anytime @oxfordtephra.bsky.social

A photo of a whiteboard with doodles on it. In red marker is a crude sketch of an erupting volcano depositing ash in the sediments beneath a lake. Some strange dancing figures appear (are they volcanic bombs with legs?!) in the distal zone. Above the volcano someone has drawn a face with long hair and glasses (that could be a few of us in the lab past/present) and written “Oxford Tephra says Hi!!” In upper case. There is also an irregular spiky tephra shard outline. You can make out the feint reflection of the photographer and an academic poster on the wall opposite.

Megadrought Reveals Volcanic Ash at Lake Mead

Volcanic ash from volcanoes in Wyoming, Idaho, and California was deposited in the rocks along the shore. The ash samples ranged from 6 million to 12 million years old.

Volcanic ash is a silent killer, more so than lava: What Alaska needs to know with Mount Spurr likely to erupt

When volcanoes like Alaska’s Mount Spurr erupt, the ash can damage people’s lungs, smother crops and kill animals, and the harm can continue to spread long afterward.

Welcome home, my beloveds, to #FossilFriday 🧪⚒️.

I've spent most of the week deep in the collection, trying to get a basic count together as we look at moving to a new home. Sometimes you find things you never realized were there all along. Here, plant fossils from the Florissant Fm.

Wow! Huge changes in federal funding for grad students and post-docs. They have gone up in value AND 15% of PhD and 20% of post-doctoral fellowships are available to non-citizens. Me and my crew at VARG @tephrotastic.bsky.social always are interested in new colleagues! Finally good news!

…Here’s a close up of a beautiful microvesicular glass shard from the ~8 kyr BP Mercato tephra, sampled near Naples 🤩

A greyscale SEM close up of a vesicular (shaped by gas bubbles) microscopic volcanic glass shard. Curved glass surfaces, bubble forms, some dust particles and some delamination (hydration?) of the glass can be seen. A scale bar indicates the whole image is less than 200 microns across. Text at the top says “Cambridge Tephra Lab”.
