Name: Carbon_Nitrogen_Organic_Isotopes

Display Field: GA_Sample_ID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This data layer comprises bulk organic carbon and nitrogen concentrations (and isotopes) from the upper 2 cm of seabed sediment. Bottom sediments were collected using either a Smith McIntyre grab or a Box Core. Surface sediments (~0-2 cm) within the grab were spooned into falcon vials and the pore waters were removed by centrifugation. The samples were then frozen for transport to the laboratories at Geoscience Australia where they were freeze-dried, ground in a tungsten carbide mill and decarbonated. The decarbonated powders were sent to Environmental Isotopes Pty Ltd (Sydney) for isotopic analysis by mass spectrometry. Samples were back-corrected to account for the carbonate removal, using carbonate concentrations derived from the bomb method. Error estimates for the C and N isotope values are ±0.15. The carbonate measurements (used to back correct) were better than 5%.
