Christine Burrill

The goal of Christine’s work is to demonstrate which cosmogenic production scaling model produces correct numerical ages for multiple lava flows on Mount Erebus, Antarctica by comparing ³⁶Cl and ³He exposure ages to ⁴⁰Ar/³⁹Ar-produced ages. The secondary goal of the project is to test whether cosmogenic nuclides should be scaled individually or uniformly by measuring the ³He/³⁶Cl ratio of lava flows from a range of elevations on Mount Erebus. In performing these tests, we will also have the data to establish the first local cosmogenic nuclide calibration site in Antarctica, which will be applicable to broader areas of research. ⁴⁰Ar/³⁹Ar ages from numerous lava flows on the flanks Mount Erebus, most of which have never been sampled before, will hopefully help us better understand the evolution of the volcano. Similarly, ⁴⁰Ar/³⁹Ar ages from lava flows on Mount Waesche will help us understand whether there is a pattern to locations of vents, compositional changes, or frequency of eruptions and if there’s any connection between volcanism and tectonics or ice sheet levels.

Brandon Dennis

— Deju Family Bright Star Intern

Bachelors — 2022, Computer Science, New Mexico Tech

In his fourth year of Bright Star funding, Brandon is working with the Bureau IT group, mainly focusing on generating web forms to replace Microsoft Access forms. He also continues assists Chris Armijo on various support challenges. In past years, Brandon played a key role in migrating a database on a USGS-funded research project in the Gallinas Mountains from MS Access to MS SQL Server. This change helped eliminate many of the challenges associated with multiple researchers managing data in a MS Access database. The process developed for the Gallinas migration is being tested on other MS Access databases within the Bureau, specifically one focusing on New Mexico Mines. Brandon will be assisting Mark Leo-Russell in setting up the database for DOE-funded REE in Coal project. Brandon is also working on a project to evaluate software tools to generate web forms for simple data entry and edit functions. The goal is to develop a documented process for generating web forms which could be used in place of MS Access for data entry and edits where appropriate.Brandon also was recently first author on a paper entitled: Comparative Analysis of Object Visualization Tools with Respect to Their Use in Education

Anne Dunn

— Deju Family Bright Star Intern

Bachelors — 2024, Materials Engineering, New Mexico Tech

In her Bright Star project, Anne Dunn is working on molecular dynamic simulations of quartz breakage, resulting from an applied shear stress, in an aqueous environment. Water molecules affect the Si-O bonds at the outer quartz surface, through solvation, and along the fracture surface (possible cleavage surface) as the fracture propagates through the quartz structure, the process known as stress corrosion.
Most of us were taught in introductory geology that one of the integral properties of quartz is conchoidal fracture (and the absence of cleavage). It turns out that this is not exactly true. Rapid breakage does result in conchoidal fracture, but quartz can exhibit cleavage and it is not uncommon in samples found in certain types of geologic environments.
It has been hypothesized that slow fracture propagation in the presence of an aqueous fluid, through the process of stress corrosion, may lead to the development of quartz cleavage planes. This video, courtesy of Alan Hart, shows a particularly striking example. This is a quartz crystal that grew from a hydrothermal fluid into an open space in a vein (in Hot Springs, Arkansas). During the growth process the crystal was cleaved and the two pieces were displaced but not separated. Continuation of quartz precipitation along the cleavage plane “healed” or recombined the two pieces into what is now a single crystal again.

Identifying factors controlling flow conveyance losses in the Middle Rio Grande

Advisors and Committee Members:

Newton, Cadol, Duval

This project, which is funded by the Middle Rio Grande Conservancy District, focuses on identifying important factors that affect water conveyance efficiency along the Middle Rio Grande between San Acacia and Elephant Butte Reservoir. A suite of in situ measurements, modeling efforts, and remote sensing techniques will be used to identify the most important and potentially interacting factors leading to channel conveyance loss. Monitoring/measurements will collect continuous baseline data, but will also include campaigns focused on relevant water inputs (seasonal precipitation events, managed water release) and losses. This work will result in a series of management recommendations based on the breadth of knowledge gained from this research.

The overlapping images will be processed at the Bureau of Geology to create orthomosaic and greenness maps. These maps will be correlated to lower resolution satellite images and used to estimate vegetation evapotranspiration rates, the rate at which plants release water to the atmosphere. The project will support the important work done by land managers in New Mexico.Stephanie received the New Mexico Geological Society’s (NMGS) 2020 Frank E.

Jonnie Woody

— Deju Family Bright Star Intern

Bachelors — 2024, Biomedical Science, New Mexico Tech

Jonnie Woody learned about instrumentation and water analysis in the Bureau of Geology’s Analytical Chemistry Laboratory. She majored in biomedical science and plans to go to medical school in order to become a pediatric oncologist on the Navajo Nation. She is a tribal member of the Navajo Nation who grew up on the reservation, where she experienced firsthand the struggles Navajo people face with having limited access to clean water and addressing water rights. Her work in the analytical laboratory offers an opportunity to learn more about water quality. While at NMT, Jonnie is the vice president of the NMT AISES student club.
Following graduate, Jonnie worked at the Univerisity of New Mexico as a program coordinator on a project called NM CIRCLES Alliance which focuses on K-12 Native American student STEAM education outreach. She also worked as research associate on a project called "Healthy Tribal Nations" funded by the National Institute of Health and was an Adult Educator and Success Coach at Dine College in Crownpoint, NM.
She plans to start a Masters Program at UNM in Public Health in January 2025, and from there, work towards medical school.
