(1995) and Heller et al. (2017).\\r\\n\\r\\nFrom published and ongoing work in the Peru and Chile oxygen minimum zones an optimized methodology for Fe(II) detection by luminol has been described in Croot et al. (2019). This work details some of the challenges and limitations of using luminol for dFe(II) detection. It should be noted that as Fe(II) is a transient redox species with a short half life in oxygenated seawater that is dependent on dissolved oxygen and pH, it is not possible to archive (preserve) samples for later analysis. Intercalibrations for Fe(II) have yet to be conducted in the context of GEOTRACES studies and should be pursued where logistically possible.\n\ncdm_data_type = Other\nVARIABLES:\nStation_ID (unitless)\nStart_Date_UTC (unitless)\ntime (Start Time UTC, seconds since 1970-01-01T00:00:00Z)\nEnd_Date_UTC (unitless)\nEnd_Time_UTC (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nEnd_Latitude (Latitude, degrees North)\nEnd_Longitude (Longitude, degrees East)\nEvent_ID (unitless)\nSample_ID (unitless)\ndepth (Sample Depth, m)\nFe_II_D_CONC_BOTTLE_07ordp (nanomoles per kilogram (nmol/kg))\nSD1_Fe_II_D_CONC_BOTTLE_07ordp (nanomoles per kilogram (nmol/kg))\nFlag_Fe_II_D_CONC_BOTTLE_07ordp (unitless)\nFe_II_D_CONC_ICE (nanomoles per kilogram (nmol/kg))\nSD1_Fe_II_D_CONC_ICE (nanomoles per kilogram (nmol/kg))\nFlag_Fe_II_D_CONC_ICE (unitless)\n...

Seawater samples were collected using the ODF rosette. Both GEOTRACES samples and GO-SHIP samples from the same cruise were analyzed. Methane was analyzed using cavity ringdown spectroscopy to determine its concentration in an equilibrated headspace. Arctic waters are a possibly significant source of this Greenhouse Gas to the atmosphere and global change is likely exacerbating its release. Methane is also a potentially valuable indicator of interactions with the shelf as well as of river inputs. Dissolved methane concentrations in this section were highest over the continental shelves and slope, which supports our understanding of the major sources of methane (i.e., from microbes in oxygen-limited sediments, from gas seeps, and from gas-hydrates).\n\ncdm_data_type = Other\nVARIABLES:\nStation_ID (unitless)\nEvent_ID (unitless)\nStart_Date_UTC (unitless)\nStart_Time_UTC (unitless)\ntime (Start_iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nlatitude (Start_latitude, degrees_north)\nlongitude (Start_longitude, degrees_east)\nRosette_Position (unitless)\nSample_ID (unitless)\ndepth (Sample_depth, m)\nCH4_D_CONC_BOTTLE_fiwgyy (nanomoles per kilogram (nmol/kg))\nSD1_CH4_D_CONC_BOTTLE_fiwgyy (nanomoles per kilogram (nmol/kg))\nFlag_CH4_D_CONC_BOTTLE_fiwgyy (unitless)\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_946112_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_946112_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_946112_v1/index.htmlTable https://www.bco-dmo.org/dataset/946112 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_946112_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_946112_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_946112_v1

The fraction of aerosol trace metals that can potentially dissolve after deposition is of interest for improving knowledge of aerosol/surface ocean interactions. This dataset provides acetic acid leachable trace metal values from bulk aerosol from the Equatorial Pacific along the US GEOTRACES EPTZ transect (TN303) from Peru to Tahiti. This region is characterized as one of the lowest atmospheric deposition regimes in the ocean. Bulk aerosols were collected from the boundary layer (~15 m above sea level) using a high-volume aerosol sampler drawing approximately 1.2 cubic meters of air per minute over Whatman 41 ash-less filter discs. Despite low aerosol loadings, triplicate agreement for most samples was good for Al, Ti, V, Mn, Fe, and Cu. Away from the coast, Cd and Pb values in most samples were close to, or below detection limit. Acetic acid leaches were carried out with a combination of 25% acetic acid and a reducing agent. Leachable trace metal concentrations were determined at the University of Alaska Fairbanks by inductively coupled plasma mass spectrometry (Thermo Element-2) using external calibration curves.

In this project, we measured Be-7 concentrations in aerosol particles and in seawater samples (depths < 200 meters) collected on the GEOTRACES GP17-OCE cruise aboard R/V Roger Revelle. The cruise originated in Papeete, Tahiti, French Polynesia on 1 December 2022 and concluded on 25 January 2023 in Punta Arenas, Chile. Sixteen aerosol samples and seawater from twelve stations in the South Pacific and Southern Oceans were collected. The dataset will be used to study the deposition of trace elements and isotopes (TEIs) and upper ocean mixing processes. Aerosol deposition is an important source of TE micronutrients to open ocean areas that are far removed from riverine sources. But, while the collection aerosol of samples for TEI analysis is straightforward, estimating the deposition flux also requires an appropriate deposition velocity (i.e. deposition flux is the product of the aerosol concentration and deposition velocity). Because Be-7 is supplied to the open ocean exclusively through aerosol deposition and it is removed through radioactive decay, the water column inventory and aerosol concentration of Be-7 can be used to derive the deposition velocity applicable to aerosol TEIs. The penetration of dissolved Be-7 below the ocean mixed layer is limited by the isotope's half-life and the rate of vertical diffusive mixing. Through modeling, the shape of the Be-7 profile below the mixed layer provides an estimate for the vertical diffusivity coefficient (Kz), which can be used to calculate fluxes of chemical species (e.g. oxygen) and physical properties (e.g. heat).\n\ncdm_data_type = Other\nVARIABLES:\nStation_ID (unitless)\nEvent_ID (unitless)\nStart_Date_UTC (unitless)\nStart_Time_UTC (unitless)\ntime (Start_iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nEnd_Date_UTC (unitless)\nEnd_Time_UTC (unitless)\nEnd_ISO_DateTime_UTC (seconds since 1970-01-01T00:00:00Z)\nStart_Latitude (degrees_north)\n...

The cruise sampled formation regions for globally distributed water masses, the return flow of Pacific Deep Water into the Southern Ocean, hydrothermally influenced waters, margin waters, and a gradient of low to high productivity with varying limiting nutrients. The cruise track investigates circulation through the Antarctic Circumpolar Current (ACC) and formation of intermediate waters important for upper ocean nutrient supply. The overall circulation/productivity/export/recycling trap of this region also affects how oceanic element-element relationships develop. For Ga, its distribution can provide insight into dust delivery, which recent work has suggested may be higher than previously thought in the study area. Ga's limited reactivity also allows its distribution to be used for water mass deconvolution, which could be usefully applied to the ACC and intermediate water formation regions.

Consequently, its distribution and speciation in marine environments is an important factor in understanding the activity of marine biota. Dissolved cobalt often displays a 'hybrid' profile type, with biological uptake dominating in the surface waters and removal by scavenging onto particles in the mesopelagic and below. These scavenging processes limit the accumulation of dissolved Co in the deep ocean. The relative contributions of scavenging and surface biological uptake are variable regionally due to both chemical and biological factors: recent research shows that dCo inventories may be intimately tied to the manganese redox cycle and formation of Mn oxides, and thus is heavily influenced by oxygen availability and local microbial community structure. Variability in Co usage - and by extension, its stoichiometry with respect to macronutrients - could be the result of differing uses of and needs for Co-utilizing metalloenzymes between taxa, and the plasticity of individual organisms with regards to metal availability. This dataset includes dissolved total (dCo) and labile Co (lCo) measurements from the GP17-OCE expedition, which occurred from 1 December 2022 to 25 January 2023, and traversed the South Pacific and a portion of the Southern Ocean. dCo samples are UV-irradiated before measurement, and so include both ligand bound and free Co. lCo samples are not UV-irradiated, thus represent the free Co inventory and that which is very weakly bound. lCo can be considered as the more bioavailable fraction. These samples were analyzed using competitive ligand exchange cathodic stripping voltammetry with a hanging mercury drop electrode. The dissolved Co distribution is understudied in much of the ocean, including the Southern Ocean. Given the contribution of the Southern Ocean to global deep water formation, the influences on the dCo inventory in this region likely impact Co supply in all ocean basins.\n\ncdm_data_type = Other\nVARIABLES:\nStation_ID (unitless)\nEvent_ID (unitless)\nGear_ID (unitless)\ntime (Start_iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nStart_Date_UTC (unitless)\n...

In this project, we measured Be-7 concentrations in aerosol particles and in seawater samples (depths < 200 meters) collected on the French GEOTRACES section GS02 SWINGS cruise aboard R/V Marion-Dufresne. The cruise originated at Réunion Island on 11 January 2021 and concluded at Réunion on 8 March 2021. Nineteen aerosol samples and seawater from eleven stations in the South Indian Ocean were collected. The dataset will be used to study the deposition of trace elements and isotopes (TEIs) and upper ocean mixing processes. Aerosol deposition is an important source of TE micronutrients to open ocean areas that are far removed from riverine sources. But, while the collection aerosol of samples for TEI analysis is straightforward, estimating the deposition flux also requires an appropriate deposition velocity (i.e. deposition flux is the product of the aerosol concentration and deposition velocity). Because Be-7 is supplied to the open ocean exclusively through aerosol deposition and it is removed through radioactive decay, the water column inventory and aerosol concentration of Be-7 can be used to derive the deposition velocity applicable to aerosol TEIs.\n\ncdm_data_type = Other\nVARIABLES:\nStation_ID (unitless)\nEvent_ID (unitless)\nStart_Date_UTC (unitless)\nStart_Time_UTC (unitless)\ntime (Start_iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nEnd_Date_UTC (unitless)\nEnd_Time_UTC (unitless)\nEnd_ISO_DateTime_UTC (seconds since 1970-01-01T00:00:00Z)\nlatitude (Start_latitude, degrees_north)\nlongitude (Start_longitude, degrees_east)\nEnd_Latitude (degrees_north)\nEnd_Longitude (degrees_east)\nSample_ID (unitless)\n...
