| log in | [Western Pacific Cruise Data] - Total organic carbon, total nitrogen content; and nitrate, ammonium and oxygen isotope composition of atmospheric particulates collected aboard R/V Dong Fang Hong-3 in the western North Pacific from October 31 to December 1, 2019. (Collaborative Research: Characterization of Reactive Nitrogen in The North Pacific Atmosphere) | These data include the content of total organic carbon content, carbon isotope (13C and 14C), total nitrogen, nitrate isotope (15N), ammonium isotope (15N), and oxygen isotope (17O and 18O) composition of atmospheric particulates collected during western North Pacific Cruise. 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. Instruments used were 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 understanding the important role of atmospheric deposition to the nitrogen cycle and biogeochemistry in the ocean. These data assess the contribution of atmospheric deposition to inorganic nitrogen and were collected by Chief Scientist Zaohui, Chen (chenzhaohui@ouc.edu.cn) at the Ocean University of China.\n\ncdm_data_type = Other\nVARIABLES:\nSample_Number (unitless)\nDate (unitless)\nStart_time (unitless)\ntime (Start_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nSampling_period_h (hours (hrs))\nlatitude (degrees_north)\nlongitude (degrees_east)\nDuplicate (unitless)\nTotal_Air_Volume_L (liter (L))\nTotalAirVolume_m3 (cubmic meters (m3))\nParticleWeight_mg (miligrams (mg))\nTOC_percent (percentage (%))\nTN_percent (percentage (%))\nC_N_Ratio (unitless)\nCarbon13_12_Ratio (parts per thousand (permil) (‰))\nDelta15N_Nitrate (parts per thousand (permil) (‰))\nDelta15N_NH4 (parts per thousand (permil) (‰))\nDelta18Oxygen_Nitrate (parts per thousand (permil) (‰))\nDelta17O_Nitrate (parts per thousand (permil) (‰))\n | BCO-DMO | bcodmo_dataset_947080_v1 |
