Short summary
Short summary
The western Mediterranean suffered unprecedented marine heatwaves in 2022. We focus on the coastal ocean, which is highly vulnerable to global warming and extreme events. Using satellite and in situ observations, strong spatiotemporal variations in the marine heatwave characteristics have been observed in 2022 and over the last decade. Differences between datasets also invite us to continue with efforts to sustain multi-platform observing systems from open-ocean to coastal ocean waters.

Short summary
Short summary
The sensitivity to the wave and sea-level forcing sources in predicting a 6-month embayed beach evolution is assessed using two different morphodynamic models. After a successful model calibration using in situ data, other sources are applied. The wave source choice is critical: hindcast data provide wrong results due to an angle bias, whilst the correct dynamics are recovered with the wave conditions from an offshore buoy. The use of different sea-level sources gives no significant differences.

Short summary
Sandy beaches, shaped by tides, waves, and winds, constantly change. Studying these changes is crucial for coastal management, but obtaining detailed shoreline data is difficult and costly. Our paper introduces a unique dataset of high-resolution shorelines from five Spanish beaches collected through the CoastSnap citizen-science program. With 1721 shorelines, our dataset provides valuable information for coastal studies.
