Trace metal concentrations and lipid biomarkers used in the interpretation of a sediment record (IODP U1419) from the Gulf of Alaska (NERC Grant NE/N011112/1)
"Three spreadsheet tables of biomarker data, element ratios, and accumulation rates. Sediment samples from IODP Expedition 341, Site U1419 in the Gulf of Alaska. Site U1419 is located in 721 m water depth on the continental slope above the Khitrov basin. Extracted lipids were analysed by HPLC-MS. Two independent methods for bulk element geochemistry analyses were applied to the samples. More details available in the paper Zindorf et al., 2020 https://doi.org/10.1016/j.chemgeo.2020.119864"

Data Quality
For this study, sediment samples from IODP Expedition 341, Site U1419 in the Gulf of Alaska have been used. Site U1419 is located in 721 m water depth on the continental slope above the Khitrov basin . Five holes (A-E) were drilled (average recovery 82%) yielding a composite core length of 177 m. All depth information in this paper will be given in mbsf (meters below sea floor) on the CCSF-B depth scale (Composite Coring depth below Sea Floor), a composite depth scale combining all drilled holes at the same site and corrected for sediment expansion. Extracted lipids were analysed by HPLC-MS. Two independent methods for bulk element geochemistry analyses (i.e., wavelength-dispersive X-ray fluorescence (XRF) and inductively coupled plasma mass spectrometry (ICP-MS)) were applied to our samples.
