Stable isotopic composition of total, deionized-water-soluble, and dilute-acetic-acid-soluble aerosol iron from analysis of composite aerosol samples collected at Tudor Hill, Bermuda between Nov 2018 and March 2020

Abstract

These data include the stable isotopic composition (δ56Fe relative to the IRMM-014 standard) of total, deionized-water-soluble, and dilute-acetic-acid-soluble aerosol Fe, from analysis of composite aerosol samples collected during ~weekly intervals on the sampling tower at Tudor Hill, Bermuda, between November 2018 and March 2020. These provide estimates of the δ56Fe signature of Fe deposited to the region during the BAIT project. Dust samples were collected by staff of the Bermuda Institute of Ocean Sciences, and the Tudor Hill tower facility is managed by Dr. Andrew Peters, with funding from NSF. Aerosol sample processing was done in the laboratory of Dr. Peter Sedwick at Old Dominion University, and analysis for δ56Fe was carried out in the laboratory of Dr. Tim Conway at the University of South Florida.
