Added value of Med-CORDEX in representing sea surface temperature and MHWs
Marine heatwaves are becoming more frequent and intense, with significant implications for marine ecosystems, fisheries, tourism, and coastal communities across the Mediterranean. A new study in Ocean Science journal, led by ObsSea4Clim colleagues, assesses whether high-resolution regional climate models provide a better representation of sea surface temperatures and marine heatwaves…

ObsSea4Clim policy brief: tackling the increasing risk of marine heatwaves
Climate change dramatically reshapes the ocean conditions, manifested by ocean warming that extends from surface to subsurface waters across all ocean basins. Marine heatwaves (MHWs) are becoming more frequent, intense, and long-lasting across European seas. They are only partially predictable, and highly disruptive tomarine ecosystems, coastal communities, and ocean-based economies,…

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…
