“…Reported seasonality of dust concentrations and deposition is different on either side of the Atlantic, peaking in winter in the east (Bory et al, 2002;Fischer et al, 2016;Fomba et al, 2014;Neuer et al, 2004;Ratmeyer et al, 1999;Skonieczny et al, 2013), and in summer in the west (Jickells et al, 1998;Prospero et al, 2014). These differences can be related to seasonal atmospheric dynamics like the altitude at which the dust is transported, with dust at lower altitudes deposited close to the source in the east, while dust transported at higher altitudes can reach the remote western Atlantic ( Van der Does et al, 2016;Yu et al, 2019). In addition, most of the studies on the eastern side of the Atlantic were carried out at latitudes above the main dust cloud and the northern position of the ITCZ, which could result in the opposing seasonal signal compared to the western Atlantic.…”
