Do forest recovery + higher soil organic C elevate production of dissolved inorganic C? No, because cooling soils + lower moisture reduce soil respiration.

On the other hand, drier climate does diminish carbonate weathering + reduce DIC export

Phosphorus release and microbial community alterations in submerged areas of Qinghai Lake The formation of submerged areas in Qinghai Lake, driven by rising water levels, has resulted in substantial changes in environmental characteristics,…

As Qinghai Lake climbs the shore, newly drowned edges remobilize phosphorus. Particles and chlorophyll rise, pH and redox shift, microbes reorganize into denser networks. These zones become engines of internal loading, amplifying eutrophication risk in alpine waters. 🌐🧪

Clarifying the trophic state concept to advance macroscale freshwater science and management For over a century, ecologists have used the concept of trophic state (TS) to characterize an aquatic ecosystem's biological productivity. However, multiple TS classification schemes, each relying on....

It takes patience to have a conversation about definitions as a collaboration begins... but it is important!
"Trophic state" in lakes is one of those concepts! It really makes a difference which definition we use... @mishafredmeyer.bsky.social

New global database reveals trends in oligotrophication in aquatic ecosystems

OLIGOTREND was featured in the last @irbio-ub.bsky.social post, with a great summary of what this database consists of, and what it already tells us about #oligotrophication in aquatic ecosystems:

Assessing water quality recovery begins with a global multi-decadal database of inland and coastal ecosystems The OLIGOTREND project has compiled a comprehensive global database on long-term water quality trends in lakes, rivers and estuaries. Spanning nearly four decades (1986–2023), this publicly avai...

News of the large-scale OLIGOTREND database have reached the multi-disciplinary EurekAlert! www.eurekalert.org/news-release...

If you want to reminisce about some #EGU25 inland water GHG highlights, I wrote a little something for the BG division blog! ✍️

While the database is not exhaustive, its flexible structure and reproducible processing pipeline facilitate the inclusion of additional datasets in the future. Please get in touch with us if you feel you can help us fill the void.
OLIGOTREND v2.0 starts now!

OLIGOTREND, a global database of multi-decadal chlorophyll a and water quality time series for rivers, lakes, and estuaries Abstract. Reversed eutrophication, called oligotrophication, has been widely documented globally over the last 30 years in rivers, lakes, and estuaries. However, the absence of a comprehensive and har...

A little side project has grown into a wonderful collective effort! We're thrilled to see the #OLIGOTREND data published on #EDI, along with its detailed companion paper released in #EarthSystemScienceData.

Awesome work here from a @steps-stc.bsky.social scholar.

Scars from wildfire are even clearer when #Sentinel2 #MSI SWIR is shown instead of True Colour image.

Are you, like me, wondering about the effects of this compound event on downstream water quality?

In less than a week, the #ElsPorts mountain range near Tortosa, on the west side of the large river Ebre (Catalonia), has endured two extreme events: a 3,300 ha #wildfire, followed by #torrential rainfall (100 mm/day) in the #riucanaletes watershed... All of this is visible from space.

Although we typically consider photosynthetic allochthonous and autochthonous carbon in stream food webs, chemoautotrophic sources (ammonia or sulfur oxidation) can contribute substantially, and incorporate ancient C. Recently accepted to FWS, online at www.journals.uchicago.edu/doi/10.1086/...

El mar Mediterráneo se tropicaliza: agua a 30 grados, noches tórridas y llegada de especies invasoras La ola de calor marina marca temperaturas de récord dos meses antes de lo habitual y afecta a la salud de quienes viven en las costas españolas

El agua del Mediterráneo arde: de Málaga a Sicilia supera los 28 grados. En algunos puntos es peor: el 30 de junio, la boya de Dragonera (Baleares) marcó 30,55 ºC. “Son temperaturas de mares tropicales; si seguimos así, no sé qué va a pasar en agosto” social.elpais.com/7i1g25

🧵Junio de 2025 ha pulverizado récords.

→ Temperatura media de 23.6 °C. Supera por 0.8 °C al anterior junio más cálido: el de 2017.

→ Su carácter ha sido extremadamente cálido. Supera en nada menos que 3.5 °C el promedio del período 1991-2020.

The publisher of my recently accepted paper announces a minimum of 10 weeks to produce the proofs from the final revised version I had sent.
With the current rules of the game (unfortunately), every publication and citation matters to secure a permanent position, it is hard to wait and stay quiet.

Good morning #EGU25 !
If you are using chamber measurements in #aquatic ecosystems to calculate #GHG fluxes, you might be interested in my talk today.
I'll show how and why experts (dis)agree when it comes to estimating fluxes from concentration time series.

Announcement of projection of documentary "Salbia, a salinity threat to the river Gambia" during the EGU25 conference in Vienna. This will take place 1st of May 2025, 18:10, room E1 at the Conference Center.

We went to the #Gambia to evidence how rising salinity in the river is affecting both local communities and the ecosystem, and @milevafilms.bsky.social made a documentary about it.
It will be shown for the first time to the public next week at @egu.eu #egu25.
Don't miss it if you are there!
