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 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

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. 🌐🧪

Upcoming #WARR talks on water chemistry + pollution in substantially modified urban streams flowing through densely populated landscapes Drs. Elizabeth Herndon + Anne Jefferson @annejefferson.bsky.social REgister: psu.zoom.us/meeting/regi... @waterbarnes.bsky.social @devonkerins.bsky.social

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 esajournals.onlinelibrary.wiley.com/doi/10.1002/...

Il y a moins de 3 ans, personne n'utilisait ChatGPT. Aujourd'hui, c'est semble-t-il devenu indispensable pour des millions de Français. Mais à quel prix ? Consommation d'électricité, consommation d'eau, extraction de matières premières... l'intelligence artificielle est un gouffre énergétique.

📢 #ArticleIRBio: Dr. Camille Minaudo (IRBio–UB) publish OLIGOTREND: a global database with 4.3M water quality & chlorophyll a records 🌍💧 🔗 doi.org/10.5194/essd... Web IRBio: shorturl.at/YESFZ #AquaticEcology #RecercaUB 🗺️ Map: 1894 sampling stations worldwide!

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: www.ub.edu/irbio/new-gl...

Historical satellite imagery provides crucial insights, not only for penguin colonies but also for establishing realistic baselines to support conservation efforts and effective management across broad spatial scales. academic.oup.com/bioscience/a...

Our overview of the impressive paper by Jensen et al in PNAS about under-ice oxygen levels is out. "Small lakes are suffocating as winters warm" www.pnas.org/doi/10.1073/...

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!

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. @biologiaub.bsky.social @irbio-ub.bsky.social @sibecol.bsky.social doi.org/10.5194/essd...

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

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 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.

Sur l'engagement des scientifiques en présence de risques clairs, documentés de manière transparente & plurielle👇. Dénoncer les projets qui aggravent les risques en conscience & connaissance au détriment de l’intérêt général, l’habitabilité pour toutes&tous, est une devoir moral, éthique, humaniste.

They’ve done it again. @primavera-sound.bsky.social has been covered in artificial grass, i.e. plastic with chemicals that end up in the sea. A threat to human health, a risk to marine ecosystems, and a source of plastic pollution to the Mediterranean. Year after year. @beyondplastics.bsky.social

This is today at 6pm! #EGU25 #Geocinema

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.

#Sau, the emblematic Catalan reservoir, providing drinking water for the city of Barcelona, is filling up quickly after the recent rainfall. It's now a bit more than 50% filled, last time it happened was in July 2022. Data from #ACA and Copernicus #Sentinel2.

Work with me on getting depth-discrete profiles of water quality using high-frequency loggers and microCTD measurements! And then let’s be creative to infer mechanisms that could improve mechanistic modeling.

It's hard to comprehend the scale at which supertrawlers are murdering life in the oceans.

📣 Our new study is out now! The importance of ditches and canals in global inland water CO2 and N2O budgets @globalchangebio.bsky.social @peatymike.bsky.social @jackiewebb.bsky.social onlinelibrary.wiley.com/doi/full/10....

We are hiring a postdoc at Umeå University in aquatic ecosystem ecology. See the link for details! www.umu.se/en/work-with... @grocherros.bsky.social

🌊Study out now in @pnas.org from @msunatsci.bsky.social and a great group of collaborators! Part 2: Findings & Resources (1/10) In our previous thread, we described why algal growth and open science matter. Now let’s get to the paper 👇🏻🧪

"How much of the excess CO2 in running waters comes from in-stream respiration of organic carbon?" To answer this, Jake Diamond et al. have used 30 years of hourly data in the River Loire. This is a spectacular and inspiring work on metabolism-carbonate system interactions. doi.org/10.1002/lno....

I love this journal - it's a treasure trove of great datasets. AND another cool thing is OPEN COMMENT PERIODS ON PREPRINTS! Along with assigned reviewers, members of the science community can also comment on the preprint to help improve the manuscript. Also OLIGOTREND sounds amazing

"OLIGOTREND, towards a global database of multi-decadal #chlorophyll-a and #waterquality timeseries for #rivers, #lakes and #estuaries". 🧪 Preprint open for discussion in Earth System Science Data until end of March: essd.copernicus.org/preprints/es...

#carbon biogeochemistry & #climate scientists: a paper from 2022 that was retracted for MANY reasons has found a new home & is more extreme than the prior version. Time for experts to speak out & correct the peer-reviewed record on this topic (again). ascelibrary.org/doi/10.1061/... 🧪🌎💧

Processing some @esaearth.esa.int #Sentinel2 scenes taken over the Gambia River... Kilometers of mangroves on either side of the river flowing through the savannah make for wonderful images to work with!

🧪⚒️I have to admit, as a scientist it's bleak. So to add a bit of glimmer to your week- tune into this month's #WARR talks!

Imaginer en 2025 une ministre qui s'oppose à inscrire dans la loi "lutte" contre le changement climatique (CC) car ce serait suicidaire pour l'agriculture qui ne contribuerait en rien au CC qui, ben voyons, serait une opportunité 🤯 Là j'avoue, j’étais pas prêt. Le climatoscepticisme2.0 me dégoûte! 😡

Hydrology Paper of the Day @caminaudo.bsky.social on measuring the optical properties of a water column in Lake Geneva: processing algorithms and estimates of physical quantities; validation using remote sensing; and understanding linkages between phytoplankton light reactions and chlorophyll-a.

How can we build better predictive models? And what can AI tell us about complex ecosystem mechanisms? I’m hiring a PhD student to work with me on applying data-driven discovery methods on high-frequency lake data to begin September 2025. Application is due on May 4.

Using data from the Thetis profiler in Lake Geneva, Gupana et al. demonstrate how disentangling quenching mechanisms improves the relationship between sun-induced fluorescence with chlorophyll-a concentration estimates, with implications for remotely sensed retrievals. Read: doi.org/10.1109/JSTA...
