Der im Artikel angesprochene Erosionskanal mit Wänden aus Eis sah im März 2024 so aus. Man sieht die großen Eiskeile die mehr als die Hälfte des Volumens des Permafrostes einnehmen können.

In 2010, I had the opportunity to pass by the cliffs of Taba Ba'astakh on the Lena River near its delta. Speleothems from eroded caves were collected in 2014 and analyzed in the study by @drumbo.bsky.social et al. @speleoseb.bsky.social @scitobias.bsky.social

In 2012, there were so many cloudberries during our #permafrost fieldwork on Muostakh Island in the Laptev Sea that we cooked jam in the field camp and took it home with us.

No #fieldwork this year, so time to look back. 2017 was my fieldwork at the #Batagay Megaslump in #Siberia, the largest known retrogressive thaw slump on earth. A prime example of abrupt #permafrost thaw that exposes ancient permafrost. In two photographs, see ellipses with people for scale.
