Understanding how OMZ vertical structure changed during past glacial/interglacial cycles will help elucidate the drivers and patterns of OMZ expansion/contraction on longer timescales. \n\nHere, radiocarbon measurements from planktic and benthic foraminifera from core MAZ-1E-04 collected on cruise MAZ-I aboard the R/V El Puma in April 2015 are used to construct an age model and calculate ventilation ages. Universidad Nacional Autónoma de México financed ship time and M. Alejandro Rodríguez Ramírez directed the oceanographic campaign to retrieve the core.\n\ncdm_data_type = Other\nVARIABLES:\nPlanktic_Core_Depth (centimeter (cm))\nPlanktic_species (unitless)\nPlanktic_weight (milligrams (mg))\nRaw_planktic_14C (14C yr BP)\nPlanktic_14C_error_1_SD (14C yr BP)\nBenthic_Core_Depth (centimeters (cm))\nBenthic_species (unitless)\nBenthic_weight (milligrams (mg))\nRaw_Benthic_14C_Uvigerina_spp (14C yr BP)\nBenthic_14C_error_1_SD (14C yr BP)\nVentilation_Age_B_Atm_14C (years)\nMarine_Reservoir_Age (years)\nMRA_corrected_planktic_14C (years)\nIntcal20_corrected_planktic_14C (years before present (yr BP))\nd14C (per mil)\nRemoved_from_analyses_flag (unitless)\n | BCO-DMO | bcodmo_dataset_991470_v1 | ||||||||||||

On-ship aerosol sampling was conducted on the R/V Dong Fang Hong-3 during a cruise to the western North Pacific from October 31 to December 1, 2019. Sampling was conducted using two portable aerosol particle samplers (model 2030, Qingdao Laoying Environmental Technology Co.) with a filter size of 9 cm O.D. Recognizing the deposition of atmospheric particulates has the potential to further understanding of the role of atmospheric deposition in the carbon cycle and biogeochemistry in the ocean. These data assess the contribution of atmospheric deposition to organic carbon and were conducted by Prof. XuChen Wang of the Key Laboratory of Marine Chemistry Theory, Ocean University of China, Qingdao 266100, China.\n\ncdm_data_type = Other\nVARIABLES:\nSample_number (unitless)\nDate (unitless)\nStart_time (unitless)\ntime (Start_iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nSampling_period (hours (h))\nLatitude (degrees_north)\nlongitude (degrees_east)\nTotal_air_volume (liters (L))\nParticle_weight (milligrams (mg))\nTotal_particulates_concentration (micrograms per cubic meter (ug/m3))\nPOC (percent (%))\nTN (percent (%))\nPOC_d13C (per mil (‰))\nd14C (per mil (‰))\nd14C_stdev (per mil (‰))\nAge_14C (Year BP)\nAge_14C_stdev (Year BP)\n | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_917642_v1/index.htmlTable | https://www.bco-dmo.org/dataset/917642
