Short summary
Marine heatwave (MHW) standard detection methods use a fixed baseline, showing rising MHW frequency and intensity due to global warming. To address this, alternative approaches separate long-term warming from extreme events. Here we compare two in the Balearic Sea: a moving baseline and detrended data. From 1982 to 2023, we found a warming trend of 0.036 °C per year, with major MHWs in 2003 and 2022 identified by all methods. Only the fixed baseline shows rising MHW duration and intensity.

Understanding how the ocean moves heat, nutrients, and pollution is vital for climate studies and ecosystem health. We examined eddies in the western Mediterranean Sea using innovative satellite observations from the Surface Water and Ocean Topography mission. Compared to existing data, we detected major differences in eddy patterns. These advances improve our ability to monitor the ocean, manage marine pollution, and support sustainable maritime activities.

Short summary
The Southern Ocean helps regulate Earth's climate, and its winds have strengthened for decades, raising the question of whether the current circling Antarctica is speeding up. Using twenty-five years of satellite data, we find little evidence of this. Much of the extra wind energy seems absorbed by small swirling currents, which show signs of intensifying, while current speed and position appear fairly stable. This suggests the ocean may continue absorbing heat and carbon as winds strengthen.

Short summary
Over the last three decades, satellites have revealed rising activity of swirling ocean currents in the Mediterranean Sea. We show that the strength of this increase depends strongly on how satellite data are combined. Products that merge many satellites may give the impression of stronger changes simply because coverage improved over time. This work underlines the importance of using stable and consistent data sets to track long-term changes in ocean variability.

Short summary
This study investigates the changing pattern of the Gulf Stream over the last 3 decades as observed in the altimetric record (1993–2022). Changes in the Gulf Stream path have an effect on its speed (and associated energy) and also on waters transported towards the subpolar North Atlantic, impacting Europe's climate. The observed shifts in the paths seem to be linked to variability in the North Atlantic Ocean during winter that may play an important role.

This paper assesses the performance of the latest version (DT2021) of global gridded altimetry products distributed through the CMEMS and C3S Copernicus programs on the retrieval of sea level in the coastal zone of the European seas with respect to the previous DT2018 version. This comparison is made using an external independent dataset. DT2021 sea level products better solve the signal in the coastal band.

This work analyzes an original high-resolution data set collected in the Mediterranean Sea. The major result is the impact of a fine-scale frontal structure on the distribution of phytoplankton groups, in an area of moderate energy with oligotrophic conditions. Our results provide an in situ confirmation of the findings obtained by previous modeling studies and remote sensing about the structuring effect of the fine-scale ocean dynamics on the structure of the phytoplankton community.

Short summary
In 2024, the Mediterranean Sea experienced more marine heatwave days than any other year in the past two decades, regardless of the detection method: a fixed baseline (1982–2011), a 20-year moving baseline, or detrended temperature data. The eastern Mediterranean also recorded the highest mean durations across all methods and mean intensities under the fixed baseline. Stating the baseline used is critical in marine heatwave studies, as it affects comparability and interpretation of results.
