Sr-Nd-Hf isotopes, REEs and particle size of dust collected across the Atlantic Ocean

Saharan dust was collected using subsurface sediment traps mooried in the tropical North Atlantic Ocean in 2012-2013, and by shipboard aerosol collection during three trans-Atlantic research cruises in 2005, 2012 and 2015. The samples were analysed for radiogenic Strontium (Sr), Neodymium (Nd), and Hafnium (Hf) isotopes, rare earth element (REE; La-Lu) abundances and particle size. In addition, soil sediments from Mauritania, a potential source area, were analysed
