Abstract:
Mean I/Ca ratios, number of measurements (n) and errors for recent benthic foraminifera at different sampling sites of the Peruvian oxygen minimum zone. The variability represents the standard deviation between all measurements of the sample/standard. In addition, core locations and bottom water oxygen concentrations (O2BW) are listed. I/Ca ratios were measured with Q-ICP-MS after the protocols described in Glock et al. (2014). Samples were taken during RV Meteor cruises M77/1 and M77/2 in the framework of the SFB754.
