At University of Massachusetts Boston I have worked on two research projects one of which I am a leading author and the other a coauthor, I was able to learn and then apply my knowledge to all of the following. Prepared whole rock samples for homogenization in the Spex® ball mill, removing any rock that may have been compromised by weathering after deposition. Learned how to analyze using Spectro Benchtop, Energy Dispersive X-ray Fluorescence (ED-XRF). To obtain major elemental values including the use of USGS standards to monitor accuracy of the ED-XRF and other instrumentation. Properly perform digestions to prep and run samples for solution-based analysis on the inductively coupled plasma mass spectrometry (ICP-MS) to obtain trace elemental composition. Completing forty hours of run time experience and several training sessions on the ICP-MS. Gained training in clean room procedures and prepped solution-based samples in the clean room. Prep and ran samples on the Gas Bench isotope ratio mass spectrometry (GB-IRMS) and the elemental analyzer (EA-IRM). This process allowed us to determine the total organic and inorganic carbon, stable carbon isotopic composition (delta13C). have become familiar with marine sediment proxies used to identify paleoenvironmental conditions during deposition. including Calcium Associated Sulfate (CAS), Degree of Pyritization (DOP), and Chromium Reduced Sulfur.
