Methodology
  • SPR0901-03KC contains two cores (core 1 and core 2), with each core cut into two sections. Three core sections were scanned and the 'core 1, sec 1' is used to recover the age gap between the two sections for core 2. The cores were scanned at 200-µm resolution on an ITRAX X-ray fluorescence (XRF) core scanner (Cox Analytical Instruments) at the Large Lakes Observatory, University of Minnesota, Duluth in 2010. The scanner is equipped with a Cr X-ray tube, and operated with an 8-second scan time at 30 kV and 15 mA.
Description
  • This dataset includes scanning X-ray fluorescence (XRF) data for the core SPR0901-03KC (34.2832°N, 120.0401°W, 586 m water depth). SPR0901-03KC was collected by the research vessel R/V Sproul off Southern California in 2009.1. The research is funded by NSF OCE-0752093.

Overview: This dataset includes scanning X-ray fluorescence (XRF) data for the core SPR0901-03KC.

Methods: SPR0901-03KC contains two cores (core 1 and core 2), with each core cut into two sections. Three core sections were scanned and the 'core 1, sec 1' is used to recover the age gap between the two sections for core 2. The cores were scanned at 200-µm resolution on an ITRAX X-ray fluorescence (XRF) core scanner (Cox Analytical Instruments) at the Large Lakes Observatory, University of Minnesota, Duluth in 2010. The scanner is equipped with a Cr X-ray tube, and operated with an 8-second scan time at 30 kV and 15 mA.
