1. CEAMARC marine sediment samples [CEAMARC-200708_V3_MARINE_SEDIMENT_SAMPLES]   PARENT METADATA
Marine sediment samples were obtained from box corer, Smith-MacIntyre and Van Veen grabs. Samples were named by: 1. CEAMARC site (e.g. 16) 2. Instrument (e.g. box corer = BC; Smith-MacIntyre = GRSM; ...


2. Cape Cod Bay Marine Monitoring [gomc_161]
The Provincetown Center for Coastal Studies' Cape Cod Bay Monitoring Project was a four-year study on the effects of the treated effluent from the Boston Outfall, funded in part by the Massachusetts ...


3. Denitrifying Activity in Deep Soil Profiles [USDA0406]
The "Denitrifying Activity in Deep Soil Profiles" dataset contains data on what factors control denitrifying activity in deep soil profiles. Its purpose is to evaluate an N-based method for measuring ...


4. Firn Air Isotope and Temperature Measurements from Siple Dome and South Pole [NSIDC-0098]
This data set includes d15N, d18O/2, dO2/N2/4, d40Ar/4, d38/Ar/2, d84Kr/48, and d132Xe/96 values for air drawn from the top 15 to 50 m of firn at the South Pole (summer and winter 1998) and a site ...


5. Lower Jurassic Stable Isotope and Chemical Data [NOAA_NCDC_PALEO_2002-001]
Bulk sedimentary nitrogen-isotope (d15Ntot) data have been generated from Lower Jurassic black carbon-rich shales in the British Isles and northern Italy deposited during the Early Toarcian Oceanic ...


6. Measurements of Trapped Air from Mullins Valley, Dry Valleys, Antarctica [NSIDC-0597]
These data describe the analyses of the elemental and isotopic composition of O2, N2, and Ar and total air content made on the trapped air from three shallow ice cores (<34m depth) collected during ...


7. Nitrogen and Carbon Isotope Data from the Central Arctic Ocean [NOAA_NCDC_PALEO_2001-037]

8. Nitrogen and Oxygen Gas Isotopes in the Siple Dome and Byrd Ice Cores, Antarctica [NSIDC-0407]
This data set consists of Gas-isotopic data from the Siple Dome and and Greenland Ice Sheet Project 2 (GISP2) ice cores covering roughly the last 100,000 years (100 ka), consisting of d15N (15N/14N) ...


9. ODP1094 South Atlantic Diatom Carbon and Nitrogen Isotope Data [NOAA_NCDC_PALEO_2005-063]
High-resolution d13C and d15N records of diatom-bound organic matter (d13CD, d15ND) from ODP site 1094, South of the Polar Front, are combined with reconstructions of summer sea surface temperature ...


10. Southern Ocean Carbon and Nitrogen Isotopic Ratios [NOAA_NCDC_PALEO_2002-014]
Oceanic nutrient cycling in the Southern Ocean is supposed to have an important impact on glacial-interglacial atmospheric CO2 changes and global climate. In order to characterize such nutrient ...
