The world’s oceans cover 70% of the Earth’s surface and plays an important role in carbon cycling. Unlike coastal waters, where new nutrients are supplied by riverine or anthropogenic input, open ocean relies on atmospheric deposition as a source to waters stimulate primary productivity CO2 sequestration. Terrestrially sourced aerosols, such Saharan dust, ocean. During boreal summer, much 72 Tg aerosol is transported west from North Africa, about 18 far Caribbean. As dust across Atlantic, it...
During the “Godzilla” dust storm of June 2020, unusually high fluxes mineral traveled across Atlantic from Sahara Desert, reaching Caribbean Basin, Gulf Coast, and southeastern United States. Additionally, an eruption La Soufrière volcano on St. Vincent in April 2021 generated substantial ashfall Caribbean. While many studies have analyzed dust’s ability to relieve nutrient limitation phosphorus (P) P-stressed North Atlantic, less is known about impact extreme events other natural aerosols P...
Abstract We report results of a field campaign conducted in the Nevada desert with suite electric instruments consisting mill (FM) and short dipole antenna (SDA). Furthermore, we show that combination measurements these two allows estimation resistivity air, an important quantity is extremely difficult to measure near Earth's surface. The air found vary between 1.5 · 10 13 6 Ω m correlate changes field. Vertical DC fields amplitudes up kV −1 were observed correspond clouds dust blowing...
Abstract. The chemical processing (“aging”) of mineral dust is thought to increase light scattering efficiency, cloud droplet activation, and nutrient solubility. However, the extent African aging during long-range transport western Atlantic poorly understood. Here, we explore in wintertime samples collected from Barbados when transported at lower altitudes. Ion chromatography (IC) analysis bulk nitrate, sulfate, oxalate reaches Barbados, indicating aging. aerosol mixing state...
