    Description: A total of 125 aerosol samples were analysed for their lithium concentrations and deposition flux. Daily aerosol samples were collected from the Pacific Ocean during CLIVAR-CO2 Repeat Hydrography Sections P16 and P2. The P16 section follows 150°-152°W and was divided into two legs, a southern leg from 17°S to 71°S in January-February 2005, and a northern leg from 16°S to 56°N in February-March 2006. CLIVAR-CO2 section P2 from Japan to San Diego, along 30°N, was visited in June-August 2004. The aerosol data from both CLIVAR-CO2 sections include aerosol lithium concentration measured following digestion in HF:HNO3:HCl mixture and corrected for sea-salt contributions (Li xs total), the P16 data also includes aerosol lithium extracted with ultrapure deionised water (≥18 MΩ) by pulling 100 mL of deionised water within ten seconds through the filter (Li xs MQ). Aerosol lithium deposition flux was calculated based on the local rain rate.

    Description: During RV Sonne cruise SO289 from Valparaiso, Chile to Nouméa, New Caledonia (GEOTRACES GP21 transect) during February – April 2022 two SeaBird SBE911Plus CTD were deployed at 44 different stations. One CTD was mounted on a stainless-steel rosette and was connected to the following sensors: Pressure (Digiquartz with TC), two temperature sensors (ITS90 °C), two conductivity sensors, oxygen (SBE43), PAR (Biospherical Licor Chelsea sensor), fluorometer (Wet Labs ECO-AFL/FL), turbidity (Wet Labs ECO-NTU) and an altimeter. The second CTD was mounted on a titanium rosette used for trace metal clean collection of water samples, and was connected to the following sensors: Pressure (Digiquartz with TC), two temperature sensors (ITS90 °C), two conductivity sensors, two oxygen sensors (SBE43), transmissometer (Wet Labs C-Star), turbidity (OBS Seapoint) and an altimeter. The oxygen and salinity data were calibrated against discrete water samples.

    Description: This dataset contains concentrations of dissolved trace metals (Al, Mn, Co, Ni, Cu, Zn, Cd, and Pb), macro-nutrients (Si and PO4), major elements (Li, Ca, K, Mg, and Sr) and Pb isotope compositions (206Pb/207Pb, 208Pb/206Pb) from a time-series station (Station A, ~700 m water depth) at the Gulf of Aqaba, northern Red Sea. Vertical water column profiles were collected between January 2017 and November 2018 on a monthly-daily resolution as part of the GEOTRACES REDMAST campaign. Seawater samples were collected using GO-Flo bottles, filtered (0.2 µm) and acidified to pH〈1.8. Samples for trace metal concentrations and Pb isotopes were pre-concentrated using the the NOBIAS chelate PA-1 resin and measured using an Agilent 7500cx Magnetic Sector ICP-MS and a Thermo-Scientific Neptune Plus Multi Collector ICP-MS, respectively (Benaltabet, T., Lapid, G., & Torfstein, A. (2020). Seawater Pb concentration and isotopic composition response to daily time scale dust storms in the Gulf of Aqaba, Red Sea. Marine Chemistry, 227, 103895.‏). Macro-nutrient concentrations were measured using a Flow Injection Quik-Chem 8500 Auto-analyzer (Grasshoff, K., Kremling, K., & Ehrhardt, M. (Eds.). (2009). Methods of seawater analysis. John Wiley & Sons.‏). Major elements were analyzed as their ratio to Na by sample-standard bracketing using an Agilent Technology Varian-720 ICP-OES (Steiner, Z., Turchyn, A. V., Harpaz, E., & Silverman, J. (2018). Water chemistry reveals a significant decline in coral calcification rates in the southern Red Sea. Nature communications, 9(1), 3615.‏).

    Description: Samples were collected at six oceanographic stations during cruise CDisK-IV on board RV Kilo Moana from Hawaii to Alaska in August 2017 using an 8-barrel multi-corer. Sediment porewaters were extracted in a cold room, using Rhizon samplers inserted into pre-drilled holes in the core liner, from two cores with undisturbed sediment-water interfaces, from each multi-corer cast. Pre-treatment of the Rhizon samplers and the sampling protocol was different for each of the two cores. Rhizons inserted to core number 1 from each cast were new from the box, and the samples were used for nutrient and major element analyses. A 20 ml syringe was filled from each Rhizon, inserted dry, and the extracted water was filtered again via a 0.45 µm filter. Rhizons inserted to core number 2 were acid-cleaned with 0.001 N HNO3 for at least 24 hours, rinsed with de-ionised water (Milli-Q, Millipore) and kept in de-ionised water until use. The first 1 mL extracted was discarded, and the next 2 mL were stored in acid cleaned polypropylene (PP) vials. These samples, destined for analyses of trace and major elements, were acidified with HNO3 to final acid concentration of 0.035 M.

    Description: Duplicate cores from each station were incubated in a cold room (2°C) for 6-14 days to provide constraints on elemental fluxes to and from the seafloor. An incubation cap was inserted into each core, and the water level adjusted to ~12 cm above the sediment surface. A 12 V motor in the incubation cap stirred the overlying water at 30 rpm. 5-7 samples were collected during the incubation period and filtered through 0.45 µm PES filters. The table provides information regarding the change in overlying water concentrations of Ca, Sr, K and Mg during the incubation experiments.

    Description: Sediment PIC concentration profiles were determined from dried and ground sediment powder. Splits were weighed into 10 mL exetainer test tubes (5-20 mg) and acidified with 10% phosphoric acid. The evolved CO2 was measured using a Picarro 2131i. Total CO2 in the Picarro analysis was standardized by running known masses of optical grade calcite standard material.
