<![CDATA[Ingalls Lab at Penn State - Updates]]>Thu, 11 Dec 2025 02:12:37 -0800Weebly<![CDATA[New papers!]]>Tue, 15 Jul 2025 19:39:19 GMThttps://www.ingallslab.com/updates/new-papersIt's been awhile.... We've had several new papers come out in the group!

Former postdoc, Allie Wyman, published her work on anomalously cool clumped isotope-derived temperatures in lagoon carbonates from Kiritimati Lagoon: PDF here: the_depositional_record_-_2025_-__-_anomalously_cool_clumped_isotope_temperatures_in_tropical_lagoon.pdf

​Hanna Leapaldt published her work on trace metal partitioning into cyanobacterially mediated carbonates from her growth experiments! PDF: minerals_-_2025-_leapaldt.pdf

Old friend and colleague, Russell Shapiro (CSU-Chico), and I published a project we started in 2019 on ancient methane seeps in California in Sedimentology: sedimentology_-_2024_-_shapiro_-_challenges_to_the_ancient_methane_seep_search_strategy__the_bedford_canyon_formation_.pdf

AND both of our papers from the EPA-funded work in the Florida Keys on the fate of shallowly injected wastewater effluent have come out in the past year: 
Phosphate! acs_es_t_-_2024_-_meyers.pdf
Nitrogen! the_depositional_record_-_2025_-_ingalls_-_fate_of_wastewater_nitrogen_upon_injection_into_a_coastal_saline_groundwater.pdf

Miquela's NSF CAREER proposal, "CAREER: Understanding biosphere-geosphere coevolution through carbonate-associated phosphate, community archives, and open-access education in rural schools", was fully funded! This award will support two graduate students, six undergraduate students, and several local high school teachers in Central Pennsylvania to reconstruct the evolution of the global P cycle through the Proterozoic and develop Earth history curricula for rural high schools. The full description can be found here.]]><![CDATA[James Lee Wilson Award]]>Thu, 01 Feb 2024 08:00:00 GMThttps://www.ingallslab.com/updates/james-lee-wilson-awardMiquela was named the 2023 James Lee Wilson awardee for excellence in sedimentary geology by an early career geoscientist, adding to her affinity of awards endowed by the Wilsons of geology's yesteryear.

Hanna will officially be a NASA fellow 2023-2026. Congrats, Hanna!!]]><![CDATA[New paper out on clumped isotope systematics of hydrated carbonate transformations]]>Mon, 01 May 2023 20:11:24 GMThttps://www.ingallslab.com/updates/new-paper-out-on-clumped-isotope-systematics-of-hydrated-carbonate-transformationsCongratulations to friend-of-the-group, Eva Scheller, on FINALLY seeing one of her first PhD projects at Caltech out in the light of day many years later!!! Eva and I worked on these ikaite transformation experiments her first two years at Caltech. She's now a postdoc at MIT. Science, folks. It takes time, particularly in a pandemic!

Cole Stern, hailing from Ogden, Utah, will be joining us as a PhD student and University Graduate Fellow (so fancy). Cole is deeply interested in deep time. Cole will work on questions related to the role of phosphate in early Earth biogeochemistry and microbial evolution!

Dr. Ellen Olsen will be joining us as a postdoc and lab manager starting in August. Ellen recently defended her dissertation on stable isotope systematics of calcite at the University of Oregon. Ellen will be steering the 253+/IBEX ship while also working on our recently funded NSF project on clumped isotope kinetics of abiotic terrestrial carbonates.

Hanna also recently received a fellowship from the Biogeochemistry Dual Title program for the 2022-23 year. Congrats, Hanna!
]]><![CDATA[Fieldwork in the Wind River Basin, WY]]>Mon, 25 Jul 2022 07:00:00 GMThttps://www.ingallslab.com/updates/fieldwork-in-the-wind-river-basin-wyRan, Miquela, and collaborator Brian Currie spent a week in the Wind River Basin, Wyoming to collect Paleocene Fort Union siderite nodules in outcrop. This sampling was a part of Ran's work understanding the impact of shallow, low-temperature diagenesis via meteoric water on iron carbonates. Ran will combine petrographic observations and stable isotopic compositions (C, O and ∆47) to reconstruct the diagenetic history of the outcrop siderites, and compare them to our cores of the same strata to investigate meteoric versus deep burial alteration.
