Determination of B/Ca of natural carbonates by HR-ICP-MS (2014)
Journal Article
Misra, S., Greaves, M., Owen, R., Kerr, J., Elmore, A., & Elderfield, H. (2014). Determination of B/Ca of natural carbonates by HR-ICP-MS. Geochemistry, Geophysics, Geosystems, 15(4), 1617-1628. https://doi.org/10.1002/2013gc005049

We report a new method for HR-ICP-MS based accurate and precise B/Ca determination from low mass natural carbonates (≤5 µg CaCO3), utilizing a mixed acid matrix (0.1 M HNO3 and 0.3 M HF) and accurate matrix matching technique. Our procedural B/Ca bla... Read More about Determination of B/Ca of natural carbonates by HR-ICP-MS.

A global evaluation of temperature and carbonate ion control on Mg/Ca ratios of ostracoda genus Krithe (2012)
Journal Article
Elmore, A., Sosdian, S., Rosenthal, Y., & Wright, J. (2012). A global evaluation of temperature and carbonate ion control on Mg/Ca ratios of ostracoda genus Krithe. Geochemistry, Geophysics, Geosystems, 13(9), Article Q09003. https://doi.org/10.1029/2012gc004073

[1] Improving estimates of past ocean temperatures is paramount to our understanding of ocean circulation and its role in climate change. Magnesium/calcium (Mg/Ca) ratios of carapaces of the benthic ostracod genus Krithe were determined from new, glo...

Testing the extraction of past seawater Nd isotopic composition from North Atlantic deep sea sediments and foraminifera (2011)
Journal Article
Elmore, A., Piotrowski, A., Wright, J., & Scrivner, A. (2011). Testing the extraction of past seawater Nd isotopic composition from North Atlantic deep sea sediments and foraminifera. Geochemistry, Geophysics, Geosystems, 12(9), Article Q09008. https://doi.org/10.1029/2011gc003741

Neodymium isotopes provide a paleoceanographic proxy for past deep water circulation and local weathering changes and have been measured on various authigenic marine sediment components, including fish teeth, ferromanganese oxides extracted by acid-r...
