Shocked to hear that Stream, which has given Esri huge sums of bill payer money to create an extremely basic API, has won an award from…. Esri! Trebles all round…

In our new preprint we describe in detail the software & workflows behind www.SewageMap.co.uk! One for the open environmental data nerds out there :) 💩 🧑💻 🏞️

Putting together a NERC proposal and somewhat baffled by what NERC mean when they want a Summary to be suitable for "opinion-formers". Who are these people and how am I meant to write for them?!

I don’t think this is true at all. Crushing rocks makes up 1% of all energy usage globally and is proportionally one of the biggest energy outlay of the entire mining sector (source: www.ceecthefuture.org/resources/mi...)

Really excellent news, and should never have been doubt. The original protest on Dartmoor was a hugely moving event and has sparked a new wave of R2R movement ⛰️ 🏕️ 🌱

Stop-Start data (i.e., *when* spills happened) is much more informative as it identifies potential links to rainfall, capacity etc... but only Thames Water actually readily share this data (see screenshot from sewagemap.co.uk). So, water co's don't help themselves! More open-data please!!!

The new government policy on bathing water status seems to be taking direct inspiration from the survivorship bias meme, for some reason?!?

Question for #hydrology #dataviz and #webdev folks… has anyone seen a visualisation like the below from earth.nullschool.net (by @cambecc.bsky.social)
but for river discharge not wind speed?? Sure I saw something similar previously but now can’t remember where!

Finally, On Thursday 08:30 - 12:20 I'm presenting a poster "A Role for Dynamic Topography in the Global Weathering Carbon Budget"... come learn why we think landscapes like these, uplifted by the mantle 🇦🇺 🦘⛰️🌋
, are important for controlling long-term climate! 5/5

Really pleased that my sewage pollution tracking package POOPy (github.com/AlexLipp/poopy) merged in its first public contribution (thank you github user JTC-0!), so that it can now map out polluted rivers in Wales (in real time!) 💩🏴
