Paper in press: Barium-isotopic mass balance of subduction zones

By Tristan Horner | 2020-02-05

Study led by Sune Nielsen published in Geochim. et Cosmochim. Acta exploring the ‘ins and outs’ of the Aleutian and Ryukyu Arcs, showing only minor fractionations associated with Ba mobilization from the down-going slab, thus underscoring the utility of Ba isotopes to apportion fluid sources to arc magmas. Full citation: Nielsen, S. G., Shu, Y.,…

Paper in press: Oceanic oxygen dynamics during the Ediacaran

By Tristan Horner | 2020-01-14

Study led by Haifeng Fan published in Geobiol. showing a significant perturbation to marine redox conditions during the Shuram negative C isotope excursion. Full citation: Fan, H., Nielsen, S. G., Owens, J. D., Auro, M., Shu, Y., Hardisty, D. S., Horner, T. J., Bowman, C. N., Young, S. A., & Wen, H. (2020). Constraining oceanic…

Welcome Dani!

By Tristan Horner | 2019-11-17

We’re pleased to welcome Danielle Santiago Ramos, WHOI Postdoctoral Scholar, to the NIRVANA Labs! Dani will be working with Sune Nielsen (G&G) and Frieder Klein (MC&G) on potassium isotope cycling in subduction zones.

Paper in press: Observing oxidation of iodide

By Tristan Horner | 2019-11-09

Study led by Dalton Hardisty published in Chem. Geol. reporting direct evidence of iodide oxidation under marine-analogue conditions, made possible by the development of a highly-sensitive new MC-ICP-MS method. Full citation: Hardisty, D. S., Horner, T. J., Wankel, S. D., Blusztajn, J., & Nielsen, S. G. (2020). Experimental observations of marine iodide oxidation using a…
