PhD Project PhD The Importance of Anthropogenic Vs. Natural Sources of Aerosols into the South Atlantic Ocean (SAO) PhD Aims Characterise key aerosol sources in South America and Southern Africa Characterise aerosols collected from D357 and JC068 cruises Make interpretations on anthropogenic vs. natural trace metal aerosol sources in the South Atlantic Ocean

Outline of Talk Aims & Objectives Materials & Methods Results Conclusions

Aims & Objectives Aims Characterise the major ion, trace metal and REEs concentration and isotopic ratios (of Pb, Nd and Zn) of potential sources of aerosols entering the SAO and identify characteristic sources for the proxies Objectives Identify important emission regions that transport aerosols to the SAO Collect data and samples of potential sources of these emissions Create a database of Pb, Nd and Zn isotope data and element data of these sources Identify anthropogenic vs. natural sources

Types of Sources Anthropogenic Urban AerosolTraffic emissions Road dust Fuel (e.g. gasoline, coal) Lichens Industrial EmissionIndustrial plant (e.g. smelters) and factory emissions Coal (e.g. fuel burning at power plants) Natural Natural AerosolAeolian/windblown dust Desert dust Volcanic dust Lichen Volcanic MaterialAsh Debris Soil Volcanic Rock Natural SedimentRock (e.g. rock type besides volcanic) Soil Sand Loess Riverbed sediment Sea Spray

Important Emissions Sao Paulo & Rio de Janeiro Patagonia Andes Buenos Aires Namibia South Africa Anthropogenic Urban AerosolTraffic emissions Road dust Fuel Lichens Industrial EmissionIndustrial plant and factory emissions Coal Natural Natural AerosolAeolian/windblown dust Desert dust Volcanic dust Lichen Volcanic MaterialAsh Debris Soil Volcanic Rock Natural SedimentRock (e.g. rock type besides volcanic) Soil Sand Loess Riverbed sediment Sea Spray

Sample Collection Collected and analysed/will analyse for : - Total concentration of major ions (Al, Ca, Fe, K, Mg, Na) on ICP-AES Total concentration of trace metals and REEs (Cu, Co, La, Mn, Nd, Ni, Pb, Sn, Zn, Y) on ICP-MS Pb, Nd and Zn isotopic ratios on MC-ICP-MS Pb & Nd data collected, but limited Zn data for Southern Africa sources (anthropogenic and natural) Important to collect more samples from at least Southern Africa

Source Database Pb, Nd, Zn Isotopic Ratio Database Multielement Concentration Database

Source Characterisation: Pb

Conclusion Anthropogenic Vs. Natural sources between South America and Southern Africa can be characterised using Pb isotopic ratios Anthropogenic sources between South America and Southern Africa can be characterised by Nd isotopic ratios Possibly, natural sources between South America and Southern Africa can be characterised by Nd isotopic ratios Zn identifies some variation between anthropogenic vs. natural sources but unable to distinguish between region of origin yet as dataset is limited Further work to be carried out to be able to use multielement data to characterise sources
