Scarista, Isle of Harris.
Wild, windswept and wonderful. With only a bevy of swans for company.
Yellow sands, lavender sea, solace and peace.

@zackpolanski.bsky.social @garyseconomics.bsky.social time to share these statistics with the UK and reform supporters?

Typhoon leaves flooded Alaska villages facing a storm recovery far tougher than most Americans will ever experience ‘As the storm approached Alaska, everything went sideways,’ leaving people no time to evacuate and little time to prepare. An Alaska meteorologist explains what happened and the challenges ahead.

I’ve got a short piece up in The Conversation on the catastrophic flooding in Southwest Alaska from ex-typhoon Halong and the challenges of recovery work. #akwx #ExtremeWeather #Alaska #AlaskaSky

Geochemically Heterogeneous Shallow Groundwater in an Urban Stream's Floodplain Contributes Negligible Quantities of Municipal Water Types to the Stream Using tracers of drinking water and untreated wastewater (e.g., optical brighteners and F−), we determined that shallow groundwater within the floodplain of an urban stream was not a major contributo....

Urban streams can wear a municipal fingerprint even when shallow groundwater doesn’t. In Deer Creek, heterogeneity over <0.5 km and likely deeper flow paths point to layered monitoring for infrastructure and ecosystem protection. 🌐🧪

Hallooo 👋 #Berlin!
Morgen abend dahin, Hintergründe zu #MoorMuusNass und so.

Some autumn impressions of our Scottish longterm research site the Girnock - some of you have been there 😉

ah the leaves are turning and the men are giving each other prizes again the first whispers of winter

This looks powerful, but students can't look into the model if they want, right? I had a very good experience with @jpgannon.bsky.social's cuahsi.shinyapps.io/HBV-model/ for a class of ~100 bachelor students with mixed backgrounds. I definitely recommend it. We need more of these educational apps!

In the tail winds (gales) of a diminishing storm (Amy).

A day when light, colour, sound and perspective play with the mind...

Congrats Maria we are all so proud of you securing this prestigious junior research group!

Thanks Matthias - and what a great meeting it was in Whitehorse!

Hot off the press! New paper characterizing storage and release processes in two permafrost catchments with @theoryofciaran.bsky.social @seankcarey.bsky.social. We characterized these processes by closing the water balance, EMMA, and StorAge Selection Functions (1/n) doi.org/10.1029/2024...

Super congrats to my long term collaborator, friend (and best husband) Chris Soulsby University of Aberdeen (not on Bluesky) for receiving the Langbein Lecture of the Hydrology Section. We couldn’t be prouder of you, it shows that hard work, mentoring, humbleness and kindness is still important! 🥳

🏆 AGU is excited to announce the recipients of the 2025 Union Medals, Awards and Prizes; Fellows; and Section Awards and Lectures. Honorees will be recognized this December in New Orleans, LA at #AGU25.

Yes a shame that none of the links is working

Great to see some natural regeneration of Scots Pine in the Cairngorms- usually on Estates which keep deer numbers at a normal rate (and don’t artificially keep numbers up for sport shooting). Then trees are just coming back … for free

St Cyrus Beach - just clouds, sky, the sea …

A week away from the autumn equinox and we're blessed with this...
Layers of gold, a whisper of cool wind, moth wings and a soothing peace.

I hope you can find solace wherever you are.

Sunset views across the croft and sea to Skye.

Happy cloud appreciation day!

Verborgene Spuren: Was der Mensch am Ostseeboden hinterlässt Geologen dokumentieren systematisch den Ostseeboden: Von Schleppnetzen bis zu mysteriösen Dreiecksstrukturen - auf einem Drittel der untersuchten Fläche hinterließ der Mensch seine Spuren

Vernarbter Boden: Es sieht aus wie ein #Kunstwerk, ist aber zerstörter #Meeresboden. Mithilfe eines akustischen Röntgenbilds machen Geologïnnen die Spuren von Schleppnetzen, Sprengungen und Ankern in der #Ostsee sichtbar: @tomma.bsky.social

🌊 This week in our #AGU25 #CatchmentHydrology Early Career series, we highlight: “Deciphering surface water–groundwater connectivity using chemical and stable isotope tracers (H and O) in the headwaters of São Francisco River, Brazil” by Marcela Aragão et al. (2025).

… and trying to do tree regeneration in tiny plots near the stream (which don’t even provide shading!) when 99% of the catchment area is overgrazed and burned! Whom are they kidding by calling it “re-gen”?

Today REALLY bad examples of land management in the Scottish Highlands: burning heather up to the stream, then being surprised about soil and land erosion!

Sieht aus wie ne "normale" Landschaft.
Aber wenn du mit bloßen Händen n Bohrer, oft viele Meter, in den Boden stecken kannst, dann ist es Torf und damit ein Moor.

Hier 👇 ein sogenanntes #Deckenmoor (Blanket Bog), typisch für die Britischen Inseln. Diesen Moortyp gibt es in Mitteleuropa nicht.

Council says street light dimming trial saved nearly £540,000 The council is considering fully adopting a scheme that sees lights dimmed to 30% brightness between 20:00 and 07:00.

HALF A MILLION POUNDS
