Short summary
Short summary
Coastal flooding is becoming more frequent and damaging, but warnings often rely on single forecasts that miss important uncertainty. We developed and tested a new early warning approach that uses multiple weather scenarios to better describe possible flood outcomes, while reducing computing costs. Applied to severe storms in northern Italy, the method preserved key information and showed that reliable flood alerts can be produced efficiently, supporting practical early warning systems.

Short summary
In the Western Alboran Gyre, waters from the Atlantic and Mediterranean meet, creating density differences that cause some water to sink, affecting ocean ventilation and nutrient cycles. We collected data showing patches of water with higher oxygen and chlorophyll levels moving towards the gyre's center, with active mixing at their edges. This mixing diluted the patches, and other factors like water density and light penetration likely played a role in these dynamics.
