Wet and dry deposition fluxes of soluble elements in the Canary region (2002-2022)
In this work, a data set of 20 years of dry (DD) and wet (WD) depositional fluxes in the Canary Islands region for the period February 2002 to February 2022 is presented. This is the longest time series of depositional fluxes in the eastern North Atlantic to our knowledge. The samples were collected...

Using the results obtained from Principal Component Analysis (PCA), a multivariate statistical method, three main sources from DD fluxes have been determined: marine (Na+, Cl-, K+, Mg2+), crustal-anthropogenic mixed (Ca2+, PO4 3-, C2O4 2-, HCOO-, CH3COO-) and anthropogenic source (NO3 -, nssSO4 2-). Besides WD fluxes were characterized mainly by a marine component (Na+, Br-, Cl-, Mg2+) and two different anthropogenic sources: (HCOO-, CH3COO-, NH4 +) and (NO3 -, nss-Ca2+, nss-SO4 2-). Although WD accounted for only 8.42 % of the total particle flux in the study period, the amount of atmospheric soluble metal inputs to the Region increased significantly during the raining seasons (more than 50% of the total Fe flux). 74 73 2 Conference Object North Atlantic Universidad de Las Palmas de Gran Canaria: Acceda |
