| dc.description.abstract | Ground-level concentrations of particulate matter with less than 10μm in diameter were measured in Azores Archipelago, mid-North Atlantic Ocean. Three intensive research campaigns took place between April and August 99. Observed average concentrations were 3.28±2.16 μgmˉ³ for non-sea-salt sulphate, 0.98±0.72μgmˉ³ for nitrate and 0.57±0.44μgmˉ³ for ammonium. The average value for non-sea-sulphate is higher than levels previously reported for other North Atlantic sites. The higher variability in non-sea-salt sulphate data collected in Azores Region most likely reflects a contribution due to active submarine volcanoes near the collection site (10–20 miles). We tried to make the connection between mass ratio sulphate/chloride maximums and maximum volcanic activity using seismic data. Average ratio between organic carbon and black carbon concentrations is 4.1±1.9. | en |
