    Details
    Publication Date: 2023-12-12
    Description: Size segregated aerosol samples were collected during the Very short lived bromine compounds in the ocean and their transport pathways into the stratosphere (TransBrom) cruise (FS Sonne, SO202) during 9 - 25 October 2009 in the western Pacific Ocean (~141 E - 146 E, 20 S – 43 N). The samples were collected by Christian Müller, Sebastian Wache and Arne Lanatowitz of GEOMAR, Kiel, Germany. The aerosol sampler was situated on the roof of the ship's wheelhouse. Samples were collected using a Sierra-type cascade impactor to separate the aerosol particles at an aerodynamic diameter cutoff of 1 µm. Collection time for the samples varied between 20.3 and 26.8 hours. Samples were extracted with ultrapure water and the major ions Na+, NH4+, Mg2+, K+, Ca2+, Cl-, NO3-, SO42-, oxalate, Br- and methanesulfonate were determined by ion chromatography (IC). Total soluble iodine (TSI) was determined by inductively coupled plasma - mass spectrometry (ICP-MS) and iodide (I-) and iodate (IO3-) were determined by IC-ICP-MS. The dataset contains the atmospheric concentrations of all measured soluble major ions (in nmol/m³) and iodine species (in pmol/m³).

    Aerosol chemical composition (major ions and iodine species) in samples collected during the M138 cruise in the eastern Pacific Ocean, June 2017 (2021)
    PANGAEA
    Details
    Publication Date: 2024-06-25
    Description: Size segregated aerosol samples were collected during the M138 cruise (FS Meteor) during 6 June - 1 July 2017 in the eastern Pacific Ocean (~86 W - 76 W, 16 S – 5 N). The samples were collected by Hermann Bange of GEOMAR, Kiel, Germany. The aerosol sampler was situated on the roof of the ship's wheelhouse and its operation was controlled by an automatic wind sector controller to prevent contamination from the ship's stack. Samples were collected using a Sierra-type cascade impactor to separate the aerosol particles at an aerodynamic diameter cutoff of 1 µm. Collection time for these samples varied between 14.3 and 65.2 hours. Samples were extracted with ultrapure water and the major ions Na+, NH4+, Mg2+, K+, Ca2+, Cl-, NO3-, SO42-, oxalate, Br- and methanesulfonate were determined by ion chromatography (IC). Total soluble iodine (TSI) was determined by inductively coupled plasma - mass spectrometry (ICP-MS) and iodide (I-) and iodate (IO3-) were determined by IC-ICP-MS. Analysis work was performed by Andrew Smith of University of East Anglia, Norwich, UK. The dataset contains the atmospheric concentrations of all measured soluble major ions (in nmol/m³)) and iodine species (in in pmol/m³). The data are reported in “Soluble iodine speciation in marine aerosols across the Indian and Pacific Ocean basins”, E. Droste et al., Frontiers in Marine Science, in preparation, (2021).

    Description: Size segregated aerosol samples were collected during the OASIS (“Organic very short lived substances and their Air Sea Exchange from the Indian Ocean to the Stratosphere”) cruises (FS Sonne, SO234-2 & SO235) during 8 - 20 July & 23 July – 7 August 2014 in the southern Indian Ocean (~30 E - 75 E, 30 S – 5 N). The samples were collected by Birgit Quack of GEOMAR, Kiel, Germany. The aerosol sampler was situated on the roof of the ship's wheelhouse and was connected to an automatic wind sector controller to prevent contamination of the samples from the ship's stack. Most samples were collected using a Sierra-type cascade impactor to separate the aerosol particles at an aerodynamic diameter cutoff of 1 µm. Collection time for these samples varied between 27.7 and 46.9 hours. For one sample, 6 impactor stages and a backup filter were used to give more detailed information aerosol size distribution. This sample was collected over 91.7 hours. Samples were extracted with ultrapure water and the major ions Na+, NH4+, Mg2+, K+, Ca2+, Cl-, NO3-, SO42-, oxalate, Br- and methanesulfonate were determined by ion chromatography (IC). Total soluble iodine (TSI) was determined by inductively coupled plasma - mass spectrometry (ICP-MS) and iodide (I-) and iodate (IO3-) were determined by IC-ICP-MS. The dataset contains the atmospheric concentrations of all measured soluble major ions (in nmol/m³) and iodine species (in pmol/ m³).

    Atmospheric fluxes of organic N and P to the global ocean (2012)
    AGU (American Geophysical Union)
    In:  Global Biogeochemical Cycles, 26 (3). GB3026.
    Details
    Publication Date: 2020-11-04
    Description: The global tropospheric budget of gaseous and particulate non-methane organic matter (OM) is re-examined to provide a holistic view of the role that OM plays in transporting the essential nutrients nitrogen and phosphorus to the ocean. A global 3-dimensional chemistry-transport model was used to construct the first global picture of atmospheric transport and deposition of the organic nitrogen (ON) and organic phosphorus (OP) that are associated with OM, focusing on the soluble fractions of these nutrients. Model simulations agree with observations within an order of magnitude. Depending on location, the observed water soluble ON fraction ranges from similar to 3% to 90% (median of similar to 35%) of total soluble N in rainwater; soluble OP ranges from similar to 20-83% (median of similar to 35%) of total soluble phosphorus. The simulations suggest that the global ON cycle has a strong anthropogenic component with similar to 45% of the overall atmospheric source (primary and secondary) associated with anthropogenic activities. In contrast, only 10% of atmospheric OP is emitted from human activities. The model-derived present-day soluble ON and OP deposition to the global ocean is estimated to be similar to 16 Tg-N/yr and similar to 0.35 Tg-P/yr respectively with an order of magnitude uncertainty. Of these amounts similar to 40% and similar to 6%, respectively, are associated with anthropogenic activities, and 33% and 90% are recycled oceanic materials. Therefore, anthropogenic emissions are having a greater impact on the ON cycle than the OP cycle; consequently increasing emissions may increase P-limitation in the oligotrophic regions of the world's ocean that rely on atmospheric deposition as an important nutrient source.

    Impact of atmospheric deposition on the contrasting iron biogeochemistry of the North and South Atlantic Ocean (2013)

    Description: Dissolved iron (dFe) distributions and atmospheric and vertical subduction fluxes of dFe were determined in the upper water column for two meridional transects of the Atlantic Ocean. The data demonstrate the disparity between the iron biogeochemistry of the North and South Atlantic Ocean and show well-defined gradients of size fractionated iron species in surface waters between geographic provinces. The highest dFe and lowest mixed layer residence times (0.4–2.5 years) were found in the northern tropical and subtropical regions. In contrast, the South Atlantic Gyre had lower dFe concentrations (〈0.4 nM) and much longer residence times (〉5 years), presumably due to lower atmospheric inputs and more efficient biological recycling of iron in this region. Vertical input fluxes of dFe to surface waters ranged from 20 to 170 nmol m–2 d–1 in the North Atlantic and tropical provinces, whereas average fluxes of 6–13 nmol m–2 d–1 were estimated for the South Atlantic. Our estimates showed that the variable dFe distribution over the surface Atlantic (〈0.1–2.0 nM) predominantly reflected atmospheric Fe deposition fluxes (〉50% of total vertical Fe flux to surface waters) rather than upwelling or vertical mixing. This demonstrates the strength of the connection between land-derived atmospheric Fe fluxes and the biological cycling of carbon and nitrogen in the Atlantic Ocean.

    Particulate phases are key in controlling dissolved iron concentrations in the (sub)-tropical North Atlantic (2017)

    Description: The supply and bioavailability of iron (Fe) controls primary productivity and N2-fixation in large parts of the global ocean. An important, yet poorly quantified, source to the ocean is particulate Fe (pFe). Here we present the first combined dataset of particulate, labile-particulate (L-pFe) and dissolved Fe (dFe) from the (sub)-tropical North Atlantic. We show a strong relationship between L-pFe and dFe, indicating a dynamic equilibrium between these two phases whereby particles ‘buffer’ dFe and maintain the elevated concentrations observed. Moreover, L-pFe can increase the overall ‘available’ (L-pFe + dFe) Fe pool by up to 55%. The lateral shelf flux of this available Fe was similar in magnitude to observed soluble aerosol-Fe deposition, a comparison that has not been previously considered. These findings demonstrate that L-pFe is integral to Fe cycling and hence plays a role in regulating carbon cycling, warranting its’ inclusion in Fe budgets and biogeochemical models.

    The Cd isotope composition of atmospheric aerosols from the tropical Atlantic Ocean (2017)

    Description: Stable isotope compositions can potentially be used to trace atmospheric Cd inputs to the surface ocean and anthropogenic Cd emissions to the atmosphere. Both of these applications may provide valuable insights into the effects of anthropogenic activities on the cycling of Cd in the environment. However, a lack of constraints for the Cd isotope compositions of atmospheric aerosols is currently hindering such studies. Here, we present stable Cd isotope data for aerosols collected over the Tropical Atlantic Ocean. The samples feature variable proportions of mineral dust-derived and anthropogenic Cd, yet exhibit similar isotope compositions, thus negating the distinction of these Cd sources using isotopic signatures in this region. Isotopic variability between these two atmospheric Cd sources may be identified in other areas, and thus warrants further investigation. Regardless, these data provide important initial constraints on the isotope composition of atmospheric Cd inputs to the ocean.
