Short summary

This study analyzes 24 years of coastal monitoring in Normandy (Blainville-sur-Mer, Saint-Vaast-la-Hougue, Utah Beach), assessing climate change and human impact. Results show rising winter temperatures since 2013, increasing acidification at Blainville-sur-Mer, and nutrient shifts, with high ammonium in the East and declining phosphates. Nutrient limitations vary by coast. Findings emphasize the need for better nutrient management to sustain ecosystems and aquaculture amid environmental change.
