I'm a geographer fascinated by nature. Currently, I'm a postdoc at AWI. The focus of my research is the past and present dynamics of ice-rich Yedoma 'mammoth' landscapes.
Noctilucent clouds are my favourite☺️
If you’re in the Northern Hemisphere this summer, keep your head to the skies at sunset and you might be lucky enough to catch a sight of one of the rarest types of cloud on Earth.

Why embed a research vessel in Arctic ice?
To study the climate where it is changing most rapidly.
#MOSAiC was the largest Arctic expedition to date.

If you need land cover datasets for the Arctic-boreal region, here is one great option for you at 1-km resolution: essd.copernicus.org/preprints/es.... It merges several regional products and separates dozens of key land cover types (e.g. bogs, fens, pine forest, spruce forest). 🌎🏞🏔
Fusing Regional and Global Datasets to Develop a Composite Land Cover Product Across High Latitudes
Abstract. Rapid warming across the Arctic is the primary driver of widespread permafrost thaw, with far-reaching consequences for local ecosystem resilience, the regional carbon budget, and the global...

🌸Plant diversity dynamics over space and time in a warming Arctic 🌸
Our new study @nature.com analysed plant diversity change in >2000 tundra plots over 4 decades. We found that plants changed unevenly, mostly driven by warming and biotic interactions.

A note about what is going on. No NOAA sites are going dark right now, but NOAA has until July 31st to move the websites in question to a different host platform.
And who knows if there is funding for that or what the options are. We are nowhere near out of the woods.

Update: All NOAA Research websites will now remain online w/ no interruptions in service, according to a statement from the agency. The reason for the reversal isn't clear, nor is the status of the contract supporting those sites.
