Surface and Subsurface Biogeochemical Impacts of the 2019 Northeast Pacific Marine Heatwave
A new study supported by ObsSea4Clim provides a multi-model statistical approach to the dispersion monitoring services in the Mediterranean. There is growing concern about the impacts of short-term extreme conditions in the ocean, including marine heatwaves. In the summer of 2019, a marine heatwave occurred in the Northeast Pacific, similar…

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…

Outcomes of Marine Heatwaves hackathon: advancing the MHW definition
As part of the ObsSea4Clim Annual Meeting and Clustering Event, a dedicated hackathon on Marine Heatwaves (MHWs) took place on March 10-11, 2023, bringing together experts and early-career scientists to refine our understanding of MHWs definitions. The opportunity to meet in person in Sopot created perfect conditions to work efficiently…

Identification of indicators for marine extremes – MS5
ObsSea4Clim investigates extreme events in the ocean, such as marine heatwaves. For the purpose of this work, we have identified ocean indicators to study these extremes and published this list in a Milestone 5 report. What are ocean indicators? The Global Ocean Observing System (GOOS) currently defines ocean indicators as…

Marine heatwaves in the Baltic Sea
In September 2024, the Baltic Sea has experienced a marine heatwave recorded on the coast of Finland. This is the second heatwave of the year in the region, with the previous heatwave observed at the turn of May and June. Unusually high temperatures have been persisting for several weeks, exceeding…
