Moonrise over Lake Balaton on World Lake Day. (TBH I think these "World <insert some random thing here> Days are kinda dumb, but whatever).

At least so far, biggest accomplishment of the Lake Balaton project is (possibly?) being able to pronounce the city Székesfehérvár.

What's this? A paper on lake restoration that not only acknowledges but also addresses internal sediment N loading? 😱😱😱 What next, external N loading targets for Lake Erie? (Likely not, barring some retirement parties/progress.) www.sciencedirect.com/science/arti...

“The most durable solution…is still to remove the nutrient source and, ideally, remove algal biomass from the water. If you only kill algae in place, some of that biomass can break down and release nutrients back into the water, which means the bloom can return later.” phys.org/news/2026-06...

So the ‘theory’ has some validity, but there are problems (see my comments within the thread), starting with the bloom not being caused by cyanos, and the usual and incorrect ‘dismissal’ of the importance of nitrogen.

I don't need to be paid or recognized to accept a review. I need journals to better match manuscripts to my expertise (most are not even close) and give me a reasonable amount of time. How about ask me (1) are you interested, and (2) if so, how much time do you need to complete a thorough review?

Multi-layered “look what you made me do” lie. Because Norway didn’t give a him prize (it doesn’t decide winners) for ending wars (he didn’t end) the US won’t be peaceful anymore (bombing multiple countries) and will take Greenland (part of Denmark, not Norway) to stop Russia (it’d help Russia).
