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!

Close up of a sediment core with a small channel of samples removed (plus a couple of bigger gaps from previous sampling). A labelled drainpipe lies alongside, plus a centrifuge tube rack with labels filled tubes in it.

Our good old friend the Laacher See Tephra in a speleothem! #tephratastic @swinnyy.bsky.social

Excited to share our latest research published in @science.org #ScienceAdvances! 🎉
We've discovered the Laacher See eruption 🌋 in a speleothem from Germany, which allows to synchronize European and Greenland Late Glacial climate change.

Discovery of Laacher See eruption in speleothem record synchronizes Greenland and central European Late Glacial climate change
A volcanic sulfur spike links the Laacher See eruption to Greenland ice cores and synchronizes the timelines to European records.

@danmclean.bsky.social also visited the #LakeSuigetsu Fukui Varve Museum in November to give a guided #tephratastic tour of the layers. 🌋🇯🇵

You had me at tephratastic…which I believe is the aerial version of clastic-fantastic.

Respect. This may be the first time my interest has been piqued by a cricket fact! This is one #tephratastic trophy 🤩🌋🏏
icelandcricket.bsky.social Iceland Cricket @icelandcricket.bsky.social · Nov 16
The most iconic trophy in Icelandic cricket is the Volcanic Ashes. It's set in a basaltic base and stuffed full of real ash from recent volcanic eruptions in Iceland. It sits in a triple-glazed case in our cricket museum in Reykjavík and is permanently guarded.

Mt Etna keeps giving. Thanks to COT24 Catania for the recent ash sample. Prepped for delivery to volcano-keen kids and year 3 projects. #tephratastic
Three small glass vials and an old black camera film pot, on a yellow table top, containing black ash from the 15th August eruption of Mt Etna. Using a kitchen funnel to decant ash from the film pot to a small glass jar. There’s a marker pen and sample bag also on the table.

Documenting this day so we can attribute all the Mt Etna tephra we are about to find in our cryptotephra lab to the correct isochron 🫣🌋🤔🕵🏻‍♀️

6 people in outdoor gear stood on ashy ground with a mountain/volcano in the background. It’s cloudy, but clear from shorts and sone bare arms that it is still quite warm. The same 6 people, this time with a view below into the cones and lava flows on the volcanoes slopes. You can just make out the sea in a bay in the distance.

Who else could lose themselves for hours looking at volcanic ash on the SEM? 🤩🤩
These tiny glass shards show some of the textures created when gases exsolve from magma of different compositions during explosive eruptions. #tephratastic
A four panel picture of SEM images of volcanic glass particles. They all have shapes defined by bubble-relics, bubble walls or lots of small bubbles (“vesicles”) held together by smooth-surfaced, sharp-edged amorphous glass.

Welcome blue sky during a brief EPMA break. Has been a busy week on the probe but getting that Friday feeling not all of these #tephratastic samples are going to be run in this batch. Guess I’ll be back again soon…
Blue sky viewed between sandstone college buildings. An electron microprobe, which looks like a large white machine in a metal cage and has lots of large computer monitors next to it.
