Eutrophication is a significant threat to aquatic ecosystems worldwide, and the Mar Menor hypersaline lagoon exemplifies coastal at risk of algal blooms due excessive nutrient loads, nitrogen, phosphorus. These nutrients originate from various sources within lagoon’s catchment area, including urban, agricultural, livestock activities. Regular occasional loads—during flood events—produce that can significantly reduce water oxygen content cause massive mortalities, as observed in recent years. A daily growth model (Mmag) was developed better understand processes determine key elements such phosphorus water–sediment interchange deep plants effect entire ecosystem growth. The analysis be applied other wetlands around world facing similar challenges. In Menor, both nitrogen have high relevance depending on period year legacy sediments. Floods are main input (80–90%), which goes sediment released after during warm months following At end summer, regular nitrate inputs increase bloom risk. good status plants, reduces release element An integrated set measures required mean chlorophyll levels under 1 or 0.5 µgChla/L make more robust resilient.

The Mar Menor is a coastal lagoon of great socio-ecological and environmental value; in recent years, different localized episodes hypoxia eutrophication have modified the quality its waters. are due to drop dissolved oxygen levels below 4 mg/L some parts rise chlorophyll over 1.8 mg/L. Considering that monitoring watershed essential understand dynamics cause these dramatic episodes, efforts focused on carrying out periodic measurements biophysical parameters water. Taking advantage data collected versatility offered by neural networks, this paper evaluates performance dozen advanced networks oriented time series forecasted for estimation parameters. used obtained water body means sensors carried multiparameter oceanographic probe two agro-climatic stations located near Menor. For forecast, models based Time2Vec architecture, accompanied BiLSTM Transformer, offer an R2 greater than 0.95. In case a, three above 0.92. These metrics corroborated forecasting first step set used. Given satisfactory results obtained, work integrated as new parameter forecast component platform Observatory developed IMIDA. demonstrate it feasible concentration using specialized forecasts.

Submerged aquatic vegetation plays a fundamental role as habitat for the biodiversity of marine species. To carry out research and monitoring submerged more efficiently accurately, it is important to use advanced technologies such underwater robots. However, when conducting missions capture photographs videos near meadows, algae can become entangled in propellers cause vehicle failure. In this context, neurobiologically inspired control architecture proposed unmanned vehicles with redundant thrusters. The learns robot non-stationary environment combines associative learning method vector map generate transformations between spatial velocity coordinates actuator. experimental results obtained show that exhibits notable resilience capabilities while maintaining its operation face thruster failures. discussion obtained, importance highlighted context conservation meadows. Its resilience, robustness, adaptability make an effective tool challenges meet mission objectives critical environments.
