SF6 concentrations were measured onboard using a gas chromatograph equipped with an electron capture detector (GC-ECD), following gas separation via a purge-and-trap SF6 analysis system. 3He concentrations were determined at the laboratory at the Institute of Environmental Physics at the University of Bremen, using a helium isotope mass spectrometer (MAP 215-50).\n\ncdm_data_type = Other\nVARIABLES:\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\ndepth (Depth_m, m)\ntemperature_C (degrees Celsius (°C))\nsalinity (PSU)\nHe3_excess (cubic centimeters at standard temperature and pressure per gram times 10^-16 (ccSTP/g*10-16))\nSF6_pmol_kg (picomoles per kilogram (pmol/kg))\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_988658_v1_fgdc.xml | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_988658_v1_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_988658_v1/index.htmlTable | https://osprey.bco-dmo.org/dataset/988658

To predict changes in oceanic MMHg concentrations, it is important to quantify its sources and sinks. Here, we study mercury speciation in the California Current System through cruise sampling and modeling. Previous work in the California Current System has found that upwelling impacts mercury biogeochemistry by transporting mercury-enriched deep waters to productive surface waters. These upwelled waters originate within the California Undercurrent water mass and are subsequently advected as a surface water parcel to the California Current. By comparing the two major water masses, we find that the California Undercurrent contains elevated dissolved total mercury (Hg) and Dimethylmercury (DMHg) concentrations by 57% and 60%, respectively, compared to the California Current. We explain that these differences result from losses during advection, specifically scavenging and DMHg demethylation. We calculate a net DMHg demethylation rate constant of 1.8 ± 0.9% per day; and build an empirically constrained mass budget model to demonstrate that DMHg demethylation accounts for 59% of surface MMHg sources. These findings illustrate that DMHg is a significant source of MMHg in this region, challenging the current understanding of the major sources of marine MMHg. These data are associated with Adams et al., 2024 (doi: 10.21203/rs.3.rs-3909481/v1).\n\ncdm_data_type = Other\nVARIABLES:\nWater_Mass (unitless)\nStation_Name (unitless)\nISO_DateTime_PDT (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nLatitude (degrees_north)\nlongitude (degrees_east)\nTrace_Metal_Cast_Num (unitless)\ndepth (Depth_m, m)\nTemperature_C (degrees Celsius)\nSalinity_PSU (practical salinity units (PSU))\nOxygen_umol_kg (micromole per kilogram (umol/kg))\nDensity_kg_m3 (kilogram per cubed meter (kg/m^3))\n...

Determining the influence of repetitive marine heatwaves on acclimatization of reef-building corals across biological scales) | This dataset arose from a project in which we investigated how hypoxia influences coral and sea anemone early life stages by comparing hypoxia responses across larvae and juveniles of three cnidarian species representing a range of life histories: the reef-building coral Galaxea fascicularis, a broadcast spawner with horizontal transmission of endosymbiotic algae (family Symbiodiniaceae); the reef-building coral Porites astreoides, a brooder with vertical endosymbiont transmission; and the estuarine sea anemone Nematostella vectensis, a non-symbiotic broadcast spawner. Specifically, larvae were exposed to normoxic (i.e., controls) or hypoxic (dissolved oxygen < 2 mg L−1 for 6 h) conditions before being cultured (under normoxia) through the juvenile stage. Data pertaining to organismal performance—including size, ash-free dry weight, protein content, chlorophyll content, symbiont density, photosynthesis and respiration rates, photochemical yield, heat tolerance (survival and Fv/Fm), settlement rate, and swimming behavior—were collected at several time points alongside environmental variables such as temperature, salinity, and dissolved oxygen concentration.\n\ncdm_data_type = Other\nVARIABLES:\nData_filename (unitless)\nSpecies (unitless)\nTreatment (unitless)\nCohort (unitless)\nGroup (unitless)\nLife_stage (unitless)\nHours_post_treatment (hours)\nAFDW_ug_mm (µg/mm)\nChlorophyll_pg_symbiont (pg/cell)\nHours_at_36_C (hours)\nDark_adapted_Fv_Fm_1 (unitless)\nLarvae_surviving (unitless)\nTotal_larvae (unitless)\nProportion_surviving (unitless)\nPercent_surviving (percent)\n...
