Volcanic Eruption in Deep Ocean Ridge Is Witnessed by Scientists for First Time Researchers diving in a submersible in the eastern Pacific realized that the landscape they had studied the day before had been glassed over by fresh lava.

Eruptive activity wiped out all the habitats at Tica - a famous site among hydrothermal vent scientists.

An ERC-funded fluid chemistry team led by Mustafa Yucel are busy understanding the effects on deep-ocean chemistry.

The details of the new “super grants” funding instrument are being developed by the Scientific Council and will be announced soon.

🚨New preprint alert!🚨

We mapped Mo-dependent pathways across microbes and show this reliance emerged before oxygen showed up. Our results challenge assumptions about Mo scarcity on early Earth. Study led by Aya Klos!

Biology’s been metal since the very beginning🤘

Finally on board R/V Atlantis and on our way to East Pacific Rise 9 north. The team met with the submarine Alvin for the first time. We’re busy preparing labs, with safety briefings and science meetings. @whoi.edu @erc.europa.eu

Final online meeting as we finalize our preparations for our upcoming expedition to the hydrothermal vents of the East Pacific Rise. In 2 weeks we’ll board R/V Atlantis in Costa Rica! @erc.europa.eu @udelaware.bsky.social @whoi.edu @metu

hi Alessandro! No George is not sailing with us, he will be supporting us from home.

Hello, Bluesky! ☀️

We fund frontier research in Europe—bold ideas, unexpected discoveries and science that shapes the future. So it’s only fitting we’ve landed here. Sorry for being late.

Follow us for updates on ERC funding, research policy, and our grantees' discoveries.

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.

Sketch showing the main environmental settings characterized by oxygen deficiency and related processes. A: In restricted and marginal settings, such as lagoons, embayment or epicontinental seas, the freshwater influx and the evaporation flux result in a positive water balance, with low salinity water overlying more dense and salty water. The restricted exchange with the open Ocean and the nutrient delivery from land contribute to the oxygen deficiency at the bottom. Examples of this type of environment can be deep, as in the case of the Black Sea, or rather shallow, such as the marine karstic lakes of Mljet (42°47′ N, 17°21′ E; Adriatic Sea) (Wunsam et al., 1999; Sondi and Juračić, 2010) and the silled Etoliko lagoon (38°27′ N, 21°20′ S; Western Greece).

We talk a lot about ocean warming and ocean acidification... but we should also be talking more about ocean deoxygenation, as it is an ongoing problem. To understand just how bad it can get (extinction event bad), we must turn, as usual, to the geological record. 🧪⚒️🌊

thank you so much, Julie!

Countdown for April 2025 Alvin Pacific expedition is on! We will participate in this @UDelaware -led expedition in the frame of our @ERC_Research DeepTrace project. So excited to be back to this special area of the world ocean once again.

Stay tuned for updates!

line plot, each line shows one individual estimate of the ocean carbon sink from models or observation-based models. the black line shows the best estimate. Barplot at bottom right shows number of surface ocean CO2 observations.

The ocean takes up anthropogenic CO₂ emissions, 26% on average over the past decade.

The #GlobalCarbonBudget 2024 confirms that the ocean sink increased in 2023 after 3 years of stagnation due to rare triple La Niña event. 2023 was an El Niño year, with an expected increase in the sink.

There's not much good news about the new Global Carbon Budget, but here's one.

Two methods are used to estimate the ocean carbon sink; the final number (10.6 ± 1.5 GtCO₂/yr in 2023) is an average. A few years ago, there was a huge discrepancy between the two methods but they're converging. 🌊

Hi, can I join too?

So, is anyone interested in and wants to follow people doing marine biogeochemistry?
I might have a starter pack for you!
(also, I blame @malinodalen.bsky.social for this)

Spot anyone not there (maybe you?), say something.

Ocean Metaproteomics intercomparison study out. Really fun project working together with colleagues to examine this method. And Intercomparisons are really valuable to connect between dstasets across time and space in the environment bg.copernicus.org/articles/21/...

Preparations for our busy @ERC_Research DeepTrace 2025 field season have started. On board RV Lamas of @METU_IMS, we have successfully conducted the first underwater tests of the new deep-sea electrochemical analyzer, to be deployed over Pacific hydrothermal vents and Black Sea redox zone next year.

thanks David, can you please add me as well?
