Water samples from 11 venting and near venting locations were collected using a Seabird 911 conductivity, temperature, and depth (CTD) titanium rosette using conducting Kevlar wire with an oxidation-reduction potential (ORP) sensor to detect plumes. Teflon coated OTE (Ocean Test Equipment) bottles were pressurized to approximately 7 psi with 0.2 μm filtered air using an oil-free compressor. A Sartobran 300 (Sartorius) filter capsule (0.2 μm) was used to collect filtered seawater samples into clean 250 mL LDPE sample bottles. Bottles and caps were rinsed 3 times with the filtered sample before being filled. Samples were stored frozen at -20°C for organic iron-binding ligand characterization by voltammetry using competitive ligand exchange adsorptive cathodic stripping voltammetry. All dissolved organic iron-binding ligand samples were measured with a BASi controlled growth mercury electrode with an Ag/AgCl¬- reference electrode and platinum auxiliary electrode (Bioanalytical Systems Incorporated) using previously established methods for forward titrations (Buck et al., 2015, 2018; Bundy et al., 2018; Abualhaija and van den Berg, 2014; Hawkes et al., 2013 (Planet. Sci. Lett.)). Reverse titrations (Hawkes et al., 2013 (Anal. Chim. Acta)) were completed on 10 samples from Broken Spur, and TAG hydrothermal vent fields with dissolved iron concentrations between 19.01-90.25 nM.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nlatitude (Latitude_deg_n, degrees_north)\nlongitude (Longitude_deg_e, degrees_east)\nStation (unitless)\nGeotraces_ID (unitless)\ndepth (Depth_m, m)\ndFe_nM (nanomoles per liter (nmol L-1))\nL1_nM (nanomoles per liter (nmol L-1))\nL1_err_nM (nanomoles per liter (nmol L-1))\nL2_nM (nanomoles per liter (nmol L-1))\nL2_err_nM (nanomoles per liter (nmol L-1))\nL3_nM (nanomoles per liter (nmol L-1))\n...

| log in | [Trace metal and organic iron ligand data] - Trace metal and organic iron ligand data collected during the PLUME RAIDERS cruise (RR2106) on the R/V Roger Revelle from 18 September – 6 November 2021 along the 16-18ºS section of the Southern East Pacific Rise. (Collaborative Research: Are Low-Temperature Hydrothermal Vents an Important but Overlooked Source of Stabilized Dissolved Iron to the Ocean?) | This dataset includes the concentrations of total dissolvable iron and manganese, dissolved iron and manganese, and dissolved organic iron-binding ligands collected on the PLUME RAIDERS expedition. Samples were collected during the PLUME RAIDERS cruise (RR2106) on the R/V Roger Revelle from 18 September – 6 November 2021. The main study area was located along the 16-18ºS section of the Southern East Pacific Rise, and the sampling was focused near the ride crest at depths below 1,500 m. Both the total dissolvable and dissolved iron and manganese concentrations were determined shipboard using flow injection analysis. The total organic iron-binding ligand data was generated both shipboard and in the lab using competitive ligand exchange adsorptive cathodic stripping voltammetry. The siderophore concentrations were measured following a solid phase extraction step, and then eluents were measured using inductively coupled plasma mass spectrometry. The dissolvable and dissolved metal data was generated by Dr. Joe Resing and Nathan Buck at NOAA-PMEL and the ligand and siderophore data was generated by Dr. Laura Moore and Dr. Randelle Bundy at the University of Washington.\n\ncdm_data_type = Other\nVARIABLES:\nGT_number (unitless)\nCruise (unitless)\nStation (unitless)\nCast_number (unitless)\nRosette (unitless)\nSite_Name (unitless)\nStation_ID (unitless)\nBottle_Position (unitless)\nNisken_number (unitless)\nDate (unitless)\nTime_GMT (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nPressure_dbar (dbars)\ndepth (Depth_m, m)\nTemp_degC (degrees celsius)\n...
