Atmospheric deposition of the essential micronutrient, iron (Fe), can have an important influence on primary production and marine biogeochemistry. In the Arctic Ocean, the ongoing shift towards seasonal ice coverage means that summertime atmospheric deposition increasingly takes place direct to the surface ocean, rather than onto sea ice. As a result, atmospheric deposition of material emitted from natural and anthropogenic sources may become a more relevant Fe input to the region. As part of the U.S. GEOTRACES GN01 section, aerosols and precipitation samples were collected to quantify the atmospheric delivery of Fe and other trace elements to the Arctic Ocean. Aerosol Fe solubility was assessed using three different leaching approaches. The readily soluble fraction, determined by rapid exposure leaches with ultrapure water (UPW) and filtered seawater (SW) was low throughout GN01, averaging 0.7 % and 1.4 %, respectively. Solubility determined using a more aggressive acetic acid (HAc) leach as an upper limit estimate of post-deposition aerosol Fe bioavailability averaged 44 %. Comparison to Fe UPW-solubility data from winter (median 6.5 %) and springtime (median 1.9 %) aerosol samples collected during the MOSAiC expedition suggests a strong seasonality to Arctic aerosol Fe solubility, potentially associated with winter/springtime Arctic haze. Iron stable isotope analysis of GN01 total Fe (d⁵⁶Fe_Tot = +0.10 ± 0.13 ‰) and UPW-soluble Fe (d⁵⁶Fe_Sol = −0.17 ± 0.33 ‰) indicate the low summertime total Fe loading was dominated by mineral aerosols, albeit with anthropogenic contributions to the small soluble Fe fraction in some samples. Bulk deposition fluxes, calculated using the beryllium-7 method, were estimated at 0.8 ± 1.2 nmol m^-2 d^-1 UPW-soluble Fe, 1.8 ± 1.9 nmol m^-2 d^-1 SW-soluble Fe, and 46 ± 48 nmol m^-2 d^-1 HAc-soluble Fe, with the UPW-soluble Fe flux around an order of magnitude lower than that measured during the winter months.
