| Notes | X-ray CT scans of sediment cores have proved valuable tools for visualizing and analyzing the cores without disturbing them. Geologists are interested in the microbial communities present in the cores; however, X-Rays are known to kill cells. This Honors thesis discusses research done in 2017 on the potential harm that the scans might do to microbes in sediment cores. “With the knowledge gained from my study I was able determine how CT scanning affected microbial community data in geological cores I used, and whether physical and chemical properties of the cores played a role in how CT scanning impacted the microbial communities. I also determined that, according to the conditions used in my study, different approaches will not be needed to preserve microbial features in geological cores that are scanned using X-ray CT, and I therefore concluded that current approaches are appropriate for continued use.” (p.18) Nicely illustrated. |
