What triggers marine heatwaves in the Mediterranean?
Marine heatwaves – periods of unusually high sea surface temperatures – pose growing risks to both ecosystems and societies. Yet, until now, the atmospheric drivers behind these events in the Mediterranean Sea have remained uncertain. A new study supported by ObsSea4Clim and published in Nature Geoscience sheds light on these…

Is the global ocean mesoscale variability becoming more energetic?
New publication from ObsSea4Clim explores if the global ocean mesoscale variability is becoming more energetic. Why is this important? Ocean mesoscale variability, including meanders and eddies, is a crucial component of the global ocean circulation. The Eddy Kinetic Energy (EKE) of these features accounts for about 90% of the ocean’s…

D6.2 Stakeholder Reference Group setup is published!
We have just published a deliverable outlining the setup of our Stakeholder Reference Group (D6.2)! The full document is available here on Zenodo: https://zenodo.org/records/15304431 This deliverable outlines the establishment of the Stakeholder Reference Group (SRG) for the ObsSea4Clim project. The SRG provides a structured and inclusive platform for engaging diverse…

D6.1 Clustering Event Nr. 1 is published!
The Clustering Event Nr.1 took place on 11-12 March 2025 at the Institute of Oceanology, Polish Academy of Sciences (IOPAN), gathering project participants from both ObsSea4Clim and BioEcoOcean, and featuring an introduction from the third sister project, BioGeoSea. We published the insights and lessons learned from the event in this…

Constraining CMIP6 simulations for the Atlantic Water in the Arctic
New study published with support from ObsSea4Clim! The study aims to improve the representation of the Atlantic Water layer in the Arctic Ocean within #CMIP6 climate model simulations. This is crucial because Atlantic Water inflow significantly influences Arctic climate change, yet current models show large biases and uncertainty. By selecting…

EOV Reliability, Accuracy and Uncertainty Maps (V.1) are here!
We are very excited to share the first part of ObsSea4Clim Essential Ocean Variables (EOV) Reliability, Accuracy, and Uncertainty Maps (V.1) in our newest deliverable D2.1. The EOV Reliability, Accuracy, and Uncertainty Maps (V.1) focus on assessing in situ data availability and uncertainties for key parameters like temperature, salinity, and…

Studying Arctic Marginal Ice Zone
Arctic sea ice is thinning and retreating because of global warming. Thus, the region is transitioning to a new state featuring an expansion of the marginal ice zone – a region where sea ice interacts with the open ocean. A new paper published in EGUsphere explores how accurate the Global…

What is the value of ocean carbon sink? New research supported by ObsSea4Clim
Oceans are one of the key natural carbon sinks, meaning that they absorb more carbon dioxide (CO2) than they release. By absorbing ~25-30% of all anthropogenic carbon dioxide emissions, oceans create a considerable value to society. Once quantified and assessed, the information on the value of the annual ocean sink…

When are ocean practices mature, and what is best practice?
Ocean practices, which include various methods supporting ocean research and operations, are continually developed and improved to aid informed decision-making. These practices often begin with an idea from an individual or group and evolve into what might be called good or even best practices. However, this evolution of ocean practices…
