AR93 Underway!
One current—and two former—NIRVANA Lab members are aboard the R/V Neil Armstrong as she heads to the Gulf Stream. Jordyn Wemhoner (current), along with Peter Crockford and Ichiko Sugiyama (former), will be collecting seawater for decay experiments similar to those carried out on AT50-10 (CliOMZ), sampling particles with in situ pumps for cadmium isotope analysis,…
3D printing: Designs now on Thingiverse
If you’ve ever browsed our facilities page, you’ll know under ‘3D printer’ it says: “If we don’t have it—fabricate it!” Well, I finally got around to sharing the designs we’ve been using in the lab over the past few years—they’re now all available on Thingiverse. The 3D printer was purchased as I was nearing the…
Paper in press: Modeling the marine barium cycle
I’m excited to share that a new study led by Hengdi Liang, ‘Modeling the global oceanic barium cycle and implications for paleoceanographic proxies,’ is out today in Earth and Planetary Science Letters. As the title suggests, we developed a model of the global oceanic barium cycle and explored what it means for barium-based paleoceanographic proxies.…
Farewell, Ichiko!
Today we say goodbye to Ichiko Sugiyama, who wraps up her time with the NIRVANA Lab. Ichiko joined us in late 2022 to study microbial metal demand in the Eastern Tropical Pacific, working jointly with Mak Saito and myself. She sailed on the AT50-10 CliOMZ expedition, where she conducted an impressive number of isotope tracer…
Tristan tenured!
I’m delighted to share that, earlier today, the President and Director, Peter de Menocal, notified me that my application for tenure at the Woods Hole Oceanographic Institution has been granted. This is a big personal milestone, and I want to take a moment to say how deeply grateful I am; for the guidance of my…
Paper in press: Treatise on Geochemsitry
I’m pleased to share that our chapter, Tools to trace past productivity and ocean nutrients, has been published in the third edition of the Treatise on Geochemistry. My involvement in this chapter began on a flight to the 2021 AGU Fall Meeting in New Orleans. I happened to be seated near Jesse Farmer, the lead…
Congratulations Dr. Ștreangă!
Congratulations to Dr. Iulia-Mădălina Ștreangă, who successfully defended her Ph.D. thesis today! Iulia’s dissertation, Marine iodine biogeochemistry: inorganic speciation, redox dynamics, and organic complexation, is available to download from DSpace@MIT. Well done, Iulia—incredible work and a major milestone!
AGU Annual Meeting 2024
Evren Arif (SSF, 2024) is presenting his research at the AGU Annual Meeting this week in Washington, D.C. His poster, ‘Mapping Dissolved Iodide in Seawater: Insights from a Machine Learning-based Climatology’ (Poster OS21H-0677), will be featured in Session OS21H: Trace Element Distributions and Cycling Across Ocean Basins on Tuesday, December 10, from 08:30 to 12:20…
Lab Writing Retreat 2024
Seven members of the NIRVANA Labs ventured to South Dennis for our annual Lab Writing Retreat. We were once again joined by special guest Laura Motta, the newest hire in the Department of Marine Chemistry & Geochemistry. This year’s venue was the historic Obed Baxter House, White Pillars, built in 1849. Lots of exciting manuscripts…
Paper in press: Barium in the Red Sea
I’m excited to share that our recent study, led by Kim Mayfield, has been published in Frontiers in Earth Science. In this research, we set out to understand the barium cycle in the Gulf of Aqaba, located in the northern Red Sea. To do this, we collected an extensive set of samples—including aerosols, groundwater, seawater,…
