The MICS Romanian Case study is led by GeoEcoMar with support from WWF Romania, and focuses on the Carasuhat Wetlands, located in Mahmudia on the Danube Delta. The citizen-science activities (water quality monitoring, bank stability, water level) continued throughout 2021. During the winter and spring, the monitoring activities took place once per month, and during the summer and autumn they increased to twice per month. The monitoring activities were performed with the support of FreshWater Watch (FWW), who provided FWW kits for the monitoring of water quality.
