Dr. Price has been invited to present at the prestigious Gordon Research Conference on the Origin of Life, in the session “Hydrothermal Vents: Differences Between Modern and Hadean Earth”. The title of his presentation is “Extending the submarine alkaline vent model for life’s emergence to the shallow sea.” The conference will be in person Janurary 23-28, 2022 in Galveston, Texas.

Strytan 2021 was a success! Roy Price, along with SBU students Holly Rucker (M.S.) and Arlaine Sanchez (Ph.D.), and with Dr. Laurie Barge from Jet Propulsion Laboratory and Dr. Donato Giovannelli from the University of Naples, recently traveled to sample the Strytan Hydrothermal System in Eyjafjord, northern Iceland. This is part of our ongoing efforts to better understand Habitability of early Martian alkaline hydrothermal systems in the Eridania Basin. Thank you to the NASA Habitable Worlds program for funding this research!!

Congratulations to Holly Rucker for completing her MS degree, “Habitability of Eridania Lake: The Bioenergetics of an Ancient Mars Lacustrine Hydrothermal Vent compared to an Icelandic Analogue Fjord Site”. This research has impactful implications for habitability of early Martian alkaline hydrothermal vents and illustrates the limits of using Earth-based hydrothermal systems as analogs.

The Price Lab had four publications and one conference presentation in 2020! Publications include Jones et al in Astrobiology (3D Printed Minerals as Astrobiology Analogs of Hydrothermal Vent Chimneys), Lu et al. in PloS One (Bioenergetic characterization of a shallow-sea hydrothermal vent system: Milos Island, Greece), Wehrmann et al. in JSWBE (Biogeochemical Sequestration of Phosphorus in a Two-Layer Lignocellulose-Based Soil Treatment System), and finally Fryer et al. in Philosophical Transactions of the Royal Society A (Mariana serpentinite mud volcanism exhumes subducted seamount materials: implications for the origin of life). Yang Gao and Greg Henkes (SBU Geosciences) worked with the Price lab to produce the first ever “Clumped isotope geochemistry of carbonates formed in association with shallow water continental methane seeps at Prony Bay, New Caledonia and Elba, Italy“. Yang presented this work at the AGU Fall Meeting.

SETI Institute Press Release: NASA PSTAR InVADER Project to send a Robotic Laser to Explore Deep Sea Vents

OUTREACH: Dr. Price presents ‘Measuring the Geochemistry of Hydrothermal Vents’ for the InVADER Mission using “Learning Glass,” a new technology that allows presenters to write notes while maintaining face-to-face contact with students, using a transparent whiteboard and technology that reverses the writing so the students can also read what is written. The video can be viewed on the InVADER website.

Price lab just funded from the NASA Habitable Worlds program! The title of the project is “Habitability of saponite-rich hydrothermal systems of early Mars.” Funding is now available for a graduate student to join the lab on this project. Please contact Dr. Price for more information.

Roy Price’s photograph of alkaline shallow-sea hydrothermal vents featured on the cover of this month’s issue of The Royal Society’s “Interface Focus” (vol 9, no 6) journal in a special theme issue ‘The origin of life: the submarine alkaline vent theory at 30’ organised by Julyan Cartwright and Michael Russell. The cover photo caption reads “Photograph of submarine chimneys comprising carbonates and brucite (Mg[OH]2) precipitating from alkaline hydrothermal fluids, Prony Bay, off New Caledonia, kindly contributed by Roy Price (cf. Price et al. Geology 2017:45(12),1135). Comparable chimneys in the Hadean would have comprised the iron oxyhydoxide, fougerite (~Fe2[OH]5) (Russell, Geology (2017) 45 (12): 1143-1144.)”

Roy Price participates in expedition to investigate the influence of ocean acidification on coral reefs in Papua New Guinea using CO2-rich shallow-sea vents as analogs. Project video available on YouTube.

Price lab publishes on arsenic nano-particle characterization and fluxes from shallow-sea hydrothermal vents, with implications for coastal marine ecosystems and global hydrothermal fluxes of arsenic.

Price lab funded through part of NASA PSTAR: “InVADER: In-situ Vent Analysis Divebot for Exobiology Research”, for “Furthering the understanding and exploration readiness of terrestrial and planetary underwater vent systems”. See project description here. This project focuses on analysis of hydrothermal vent fluid and precipitate samples collected from the Axial Seamount on the Juan de Fuca Ridge, in support of the InVADER objectives.

The Price lab is looking for undergraduate student volunteers who are interested in assisting with cultivation of arsenotrophs – microbes who oxidize or reduce arsenic for energy and growth. Samples are in hand and ready for inoculation. Please contact Dr. Price if interested.
