New Paper Alert: Inter-chamber variability and LA-ICPMS - ICP-OES inter comparison

 Whew! This is a long title, but a new paper is now out in Scientific Reports

This paper follows up on our work in the previous Nature Communications paper, and further examines the within-individual differences in Mg/Ca in T. sacculifer. We used LA-ICPMS to get chamber-by-chamber data on over 1000 individuals and over 5000 individual measurements. That's a lot of data.

We also compared the LA-ICPMS data to same-shell Mg/Ca data obtained using ICP-OES and found a remarkable correspondence when using a weighted average of the f0 and f1 LA-ICPMS data. 

I thank my co-authors for their guidance and patience, and encourage you to take a look.
