I’ve stopped making a to-do list. But - have started keeping a ‘have done’ list that I complete at the end of every day. Typically a far more positive exercise…

A wave train entering into the North Sea, seen by #Sentinel1 on 12 August. I am guessing it's tidal-related, but I have never seen this kind of signal in this region in SAR data before, pretty cool 😎

A satellite image of the southern North Sea, showing land in white and the sea in shades of grey. A semicircular pattern between UK and France can be seen in the English Channel. White dots in the sea are windmills and ships.

👀 There have been some exciting arrivals since I joined MMU Dept Natural Sciences: flume for the BiG Lab, LaVision PIV, Dr Lizzie Dingle and her very cool experiments, some feisty crayfish 🦞, & now, Prof. @tomcoulthard.bsky.social 🥳. Chuffed to bits that Tom is now a colleague. Exciting times ahead!

I’m delighted to share that our latest research has just been published in HESS.

We developed an unsupervised workflow to estimate river surface velocities from videos. Testing on 11,000+ videos against 274 gauging measurements showed excellent agreement.

Unsupervised image velocimetry for automated computation of river flow velocities

Abstract. Accurate, long-term measurements of river flow are imperative for understanding and predicting a broad range of fluvial processes. Modern technological advances are enabling the development ...

First cloud-free optical satellite imagery from @planet.com show the destruction of Dharali village in Uttarkashi, Uttarakhand, India. Unfortunately the source area in the mountains is still obscured by cloud and so the ultimate cause is still speculative. 🧪⚒️

Incredible story. Hg production fell to zero in 2020 but now rising (illegally it seems) to propel gold extraction in the Amazon financed and facilitated by Mexicos drug cartels… Horribly toxic - I thought mercury use had been nearly eliminated.

The Guardian @theguardian.com · Jul 24

It is one of the deadliest chemicals on Earth – but even Mexico’s cartels can’t resist the lure of mercury

An undercover investigation reveals 200 tonnes of the deadly substance is being smuggled across South America, where it is poisoning rivers, soil and air

Demand management now prevents any endless recycling of crap proposals - and NERC won’t allow any props to be fed into AI - which is why they switch off auto translate on meeting recording…

Here's a fun anomaly for an inland flood risk map. It's genuinely very helpful in places: check-long-term-flood-risk.service.gov.uk/map But it's based on scans of the ground, & the processing gets confused sometimes. I think the 4-storey pitched roof of this hospital is probably safe from flooding!

Part of the "check long term flood risk" service map, with settings at future, and 20cm depth, showing blue on a large area in a grid shape.

satellite view of the same building from google maps. Some of the roof is flat but the shadows indicate it is mostly pitched.

I’m fairly sure the report remit was for E&W - as env regulation is fairly heavily devolved? There’s certainly a large section on Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿 at the beginning…
