Consistency and uncertainty in marine heatwave monitoring using multi-source satellite sst products: insights from marginal seas and open oceans

Marine Heat Waves and Cold Spells – Multiple Analysis/Definitions (MHW-MAD): A Multi-Definition Global Marine Heatwave Database from Satellite Sea Surface Temperature Data

Marine heatwaves (MHWs) are prolonged anomalies of warm sea surface temperature (SST) that can disrupt marine ecosystems, physical climate processes, and human coastal activities. MHW definitions vary due to different stakeholders requirements, such as ecological scientists and climate scientists having differing yet s...

Revealing Enhanced Signals of Future Marine Heatwave Changes in the East/Japan Sea Through a High‐Resolution Dynamical Downscaling Ensemble

The East/Japan Sea (EJS) is a semi‐enclosed marginal sea that has experienced rapid sea surface temperature (SST) warming exceeding 0.9°C since the 1980s, which has intensified the occurrence of marine heatwaves (MHWs). Its semi‐enclosed nature amplifies the influence of external climate forcing, making reliable projec...

Spatiotemporal characteristics of marine heatwaves driven by different factors in the South China Sea

Quantitative evaluation of mesoscale eddies in the North Atlantic using satellite altimetry and ocean reanalyses

Ocean mesoscale eddies (10–250 km) play a key role in transporting heat, momentum, and nutrients. Accurately evaluating their representation in ocean reanalysis becomes important given that ocean reanalysis is widely used in ocean and climate research due to their temporal and spatially consistent coverage. This study...

Intensifying concurrent marine–atmospheric heatwaves in the marginal seas of the Arabian Peninsula: implications for coral bleaching and ocean productivity

Marine heatwaves (MHWs) and atmospheric heatwaves (AHWs) are intensifying under climate change, yet their concurrent occurrence can amplify thermal stress and pose greater risks to marine ecosystems than either event alone. This study investigates the spatiotemporal variability, physical drivers, and ecological impacts...

The added value of Med-CORDEX coupled high-resolution regional climate models in representing sea surface temperature and marine heatwaves in the Mediterranean Sea

Marine heatwaves (MHWs) pose significant threats to Mediterranean marine ecosystems and coastal economies, with frequency and severity projected to increase under future climate change. While Med-CORDEX fully-coupled Regional Climate System Models (RCSMs) offer enhanced resolution and improved representation of local p...
