Mount Etna (Italy), one of the world's most active volcanoes, is located in the oligotrophic Mediterranean Sea (MedSea). Despite the active volcanism on Mount Etna, the biogeochemical impacts of volcanic ash fallouts on the marine primary productivity (MPP) remain largely unknown. Here we ...
i.e. input/output, according to land-use type. Because the results are presented in units of sej/g C, higher values of R/NPP correspond to higher required energy consumption per gram of carbon produced. This value could be used as an indicator to evaluate the productivity...
Earth has experienced intervals of glacial and interglacial periods in its history including Snowball Earth events [1,2]. Today, glaciers and ice sheets are integral to the Earth’s climate and hydrological system—they influence regional and global climate, are sensitive to climate change, and are...
ImpactsVolcanoAtmospheric chemistryTroposphereEmissionVolcanoes are an important source of aerosols to the troposphere. Within minutes after emission, volcanic plume aerosol catalyses conversion of co-emitted HBr, HCl into highly reactive halogens (e.g. BrO, OClO) through chemical cycles that cause ...
