In the last few years extreme weather events, including changes to storm frequency and intensity, have increased across all continents. In this note we assessed, for the first time in the Mediterranean Sea, the impact of a violent storm and consequent flood on offshore water contamination and benthic community along the Calabrian coast (Ionian Sea). Three sites (at 500, 1000, and 2000 m off the coast) were sampled along three parallel transects in 2013, 2014 (before), and 2015 (after the flood). After the flood, metals (especially Al, Cr, Ni, Cu, Zn) in the water column increased in concentration. The flood affected the structure of the benthic community, causing a decrease of diversity, the dominance of few opportunistic species, and the decrease of M-AMBI values.
在过去的几年里，极端天气事件，包括风暴频率和强度的变化，在各大洲都有所增加。在本说明中，我们首次评估了一次剧烈风暴和随后的洪水对沿卡拉布里亚海岸（爱奥尼亚海）的近海海水污染和海底生物群落的影响。2013 年、2014 年（洪水前）和 2015 年（洪水后），在三个平行的横断线上，在距海岸 500、1000 和 2000 米处的三个地点进行了采样。洪水过后，水柱中的金属（特别是铝、铬、镍、铜、锌）浓度增加。洪水影响了海底生物群落的结构，导致多样性减少，少数机会主义物种占主导地位，M-AMBI 值降低。
