An experiment to assess the effects of diatom dissolution on oxygen isotope ratios (2015)
Journal Article
Smith, A. C., Leng, M. J., Swann, G. E., Barker, P. A., Mackay, A. W., Ryves, D. B., Sloane, H. J., Chenery, S. R., & Hems, M. (2016). An experiment to assess the effects of diatom dissolution on oxygen isotope ratios. Rapid Communications in Mass Spectrometry, 30(2), 293-300. https://doi.org/10.1002/rcm.7446

Rationale: Current studies which use the oxygen isotope composition from diatom silica (δ18Odiatom) as a palaeoclimate proxy assume that the δ18Odiatom value reflects the isotopic composition of the water in which the diatom formed. However, diatoms... Read More about An experiment to assess the effects of diatom dissolution on oxygen isotope ratios.

In comparison to other sectors of the marine system, the palaeoceanography of the subarctic North Pacific Ocean is poorly constrained. New diatom isotope records of δ13C, δ18O δ30Si (δ13Cdiatom, δ18Odiatom and δ30Sidiatom) are presented alongside exi...

Silica stable isotopes and silicification in a carnivorous sponge Asbestopluma sp. (2015)
Journal Article

The stable isotope composition of benthic sponge spicule silica is a potential source of palaeoceanographic information about past deep seawater chemistry. The silicon isotope composition of spicules has been shown to relate to the silicic acid conce... Read More about Silica stable isotopes and silicification in a carnivorous sponge Asbestopluma sp..
