Welcome to NIRVANA
Non-traditional Isotope Research on Various Advanced Novel Applications
Though the WHOI campus remains closed, NIRVANA team members are meeting virtually to discuss their projects, publications, and plans!
Welcome back Jule!
Jule Middleton returns to Woods Hole after two months collecting samples in the Southern Ocean (Indian Sector) aboard the R/V Thomas G. Thompson (cruise TN376).
NIRVANA at Ocean Sciences Meeting
Emilie Le Roy is at the 2020 Ocean Sciences meeting in San Diego presenting her research on radium cycling along the GEOTRACES GP15 transect. Other research featuring NIRVANA team members at the meeting: Dalton Hardisty on iodide cycling in oxygen-minimum zones Laura Whitmore on barium cycling in the Arctic
Congratulations to Maureen Auro, who today was promoted to Research Associate III!
Paper in press: Barium-isotopic mass balance of subduction zones
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.

Paper in press: Oceanic oxygen dynamics during the Ediacaran
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…
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
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…
Congratulations to Ann Dunlea, who today starts her new position as Assistant Scientist in the Department of Marine Chemistry & Geochemistry at Woods Hole Oceanographic Institution.
NIRVANA in Arizona
Logan Tegler is at the 2019 Geological Society of America Annual Meeting in Phoenix presenting her research exploring primary productivity before the Great Oxidation Event.
