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.)”

Using CO2-rich shallow-sea vents as analogs to investigate the influence of ocean acidification on coral reefs in Papua New Guinea

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.


 

My research focuses on element cycling in the hydrological cycle, including:

  • Geochemical evolution of hydrothermal vent fluids, particularly shallow-sea vents.
  • Cycling of toxic elements in coastal marine environments, either naturally occurring or anthropogenic.
  • Environmental geochemistry, emphasizing source, fate, flux, transport
 and bioaccumulation of toxins.
  • Mobilization mechanisms and fate of arsenic in groundwater aquifers.
  • Abiotic vs. biotic (microbial) processes across redox gradients.
  • Shallow-sea analogs for early-Earth conditions and the origin of life.

Detailed Research Interests

shallowseavent1My research interests generally focus on element cycling in the hydrological cycle. As such, I am interested in a wide range of topics. However, my primary focus is on the geochemical evolution of hydrothermal vent fluids, particularly for shallow-sea vents, and the consequences this has for toxic metal cycling, bioaccumulation and microbial communities in these important coastal environments.

Shallow-sea hydrothermal vents are generally defined as occurring at a water depth < 200 m, a depth which marks the deepest extent of the photic zone and coincides with a large change in the slope of the seawater boiling curve. Their easy accessibility, relative to deep-sea hydrothermal systems, makes them excellent natural laboratories to study a wide range of chemical, physical, and biological processes. I’ve undertaken several research projects related to these types of hydrothermal vents. Click the link to see a brief description:

My research is not limited to hydrothermal vent research. I’ve also worked on several projects focused on understanding arsenic cycling in southwest Florida. Click here to learn more.
