| log in | [Texas fish muscle stable isotopes] - Stable isotope compositions (carbon, nitrogen, and sulfur) of muscle tissue in three species of fish from the Matagorda Bay region of Texas in the northwestern Gulf of Mexico from 2021 to 2023 (Collaborative Research: Shifting the Hypoxia Paradigm – New Directions to Explore the Spread and Impacts of Ocean/Great Lakes Deoxygenation) | This dataset describes stable isotope compositions (carbon, nitrogen, and sulfur) of muscle tissue in three species of fish (Red Drum Sciaenops ocellatus, Southern Flounder Paralichthys lethostigma, and Atlantic Croaker Micropogonias undulatus) in the Matagorda Bay region of Texas in the northwestern Gulf of Mexico. Fish carcasses were obtained from anglers at boat docks, fish cleaning stations, or other locations in the region. Fish were also obtained from bait shops where the proprietors verified the fish were sourced from the Matagorda Bay study region. These fish will be dissected to subsample white muscle tissue from each fish (skin and scales removed). Muscle samples were then dried, pulverized, and analyzed for stable isotope compositions to assess potential shifts in dietary or habitat-specific residence patterns within and between species. This dataset is part of a larger project assessing fish dietary and habitat use patterns in response to environmental stressors including hypoxia and pollutant accumulation.\n\ncdm_data_type = Other\nVARIABLES:\nFishID (unitless)\nDuplicate (unitless)\nSpecies_Code (unitless)\nSpecies (unitless)\nC13 (permil (‰))\nN15 (permil (‰))\nS34 (permil (‰))\nlatitude (Station_latitude, degrees_north)\nlongitude (Station_longitude, degrees_east)\nDate_Collected (unitless)\n | BCO-DMO | bcodmo_dataset_961706_v1 | ||||||||||||
| 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 | ||||||||||||
| log in | [Western Pacific Precipitation Data] - Total organic carbon and total nitrogen content; and nitrogen and oxygen isotope composition of precipitation collected at Qindao, Yantai and Changdao Island, China from May 17, 2019 to August 31, 2020. (Collaborative Research: Characterization of Reactive Nitrogen in The North Pacific Atmosphere) | These data include the content of total organic carbon content and total nitrogen, and nitrogen (15N) and oxygen (17O and 18O) isotope composition of precipitation collected at three fixed locations: Qindao (121°28'15\" E, 31°37'21\" N), Yantai (121°27'40\" E, 37°31'20\" N), and Changdao Island (120°45'20\" E, 38°10'23\" N) in China. the rainwater samples collected on the Changdao Island were via an automatic rainwater collector (Model XHARS30C, Jinshui Huayu Scientific Inc. Weifang, China), and all other rainwaters collected in Yantai and Qindao were via stainless buckets from May 17, 2019 to August 31, 2020. Recognizing the deposition from precipitation has the potential to understanding the important role of atmospheric deposition to the nitrogen cycle and biogeochemistry in the ocean.
