The article by Sedwick et al., 2023 is the first publication of the U.S. GEOTRACES Process Study GApr13. The study focuses on the Bermuda region of the North Atlantic Ocean, where deposition of airborne soil dust is the major source of dissolved iron (DFe) to surface waters. By combining measurements of the atmospheric loading and solubility of iron in soil dust over Bermuda with measurements of DFe in adjacent ocean waters over a full year, they estimate the rate of supply of DFe from dust deposition in this region, and the average time that this DFe persists in the surface ocean, with an estimated residence time of ∼0.8–1.9 years for DFe with respect to aeolian input. The integration of the iron analyses from water samples collected during the four seasonal Bermuda Atlantic Iron Time-series (BAIT) 2019 cruises with water samples and measurements of aerosols and rain from the Bermuda Atlantic Time-series Study (BATS) stations during that year is a great example of collaborative research sponsored by different agencies that U.S. GEOTRACES would like to promote as part of the Synthesis Phase.
