Environmental assessment and ecosystem-level research requires advanced analytical capabilities. This acquisition of a gas chromatograph with a triple quadrupole mass spectrometer will provide a previously unavailable instrument to South Texas scientists studying biogeochemical cycling and environmental contaminants. This instrument has the ability to detect and quantify thousands of compounds, including anthropogenic contaminants, that can then be studied in greater detail to assess their metabolic role or influence on ecosystems. These areas of research are vital, not only to the rapidly developing and industrialized South Texas region but throughout the northern Gulf of Mexico. Additionally, with much of this region experiencing regular extreme weather events and environmental change, this instrument will play a role in understanding how our ecosystems are adapting to this shifting reality.This instrument has capabilities that will enable a broad range of research for the faculty at Texas A&M University Corpus-Christi, but also other Hispanic Serving Institutions in our region. Some of the potential areas of research enabled by this instrument include: assessing the fate, transport and ecosystem effects of industrial and agricultural contaminants; determination of bacterial metabolites in freshwater and marine sediment; analysis of amino acids in sediment organic matter and biological matrixes; determination of natural organic matter biomarkers; analysis of atmospheric dissolved organic nitrogen. These studies will encompass basic and applied research that seeks to examine natural scientific processes and the ways in which humans are influencing our world.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

环境评估和生态系统层面的研究需要先进的分析能力。此次购买的带有三重四极杆质谱仪的气相色谱仪将为南德克萨斯州研究生物地球化学循环和环境污染物的科学家提供以前无法使用的仪器。该仪器能够检测和量化数千种化合物，包括人为污染物，然后可以对其进行更详细的研究，以评估它们的代谢作用或对生态系统的影响。这些研究领域不仅对于快速发展和工业化的德克萨斯州南部地区而且对于整个墨西哥湾北部都至关重要。此外，由于该地区的大部分地区经常经历极端天气事件和环境变化，该仪器将在了解我们的生态系统如何适应这种不断变化的现实方面发挥作用。该仪器的功能将使教员能够进行广泛的研究德克萨斯农工大学科珀斯克里斯蒂分校，以及我们地区的其他西班牙裔服务机构。该工具可实现的一些潜在研究领域包括：评估工业和农业污染物的归宿、运输和生态系统影响；淡水和海洋沉积物中细菌代谢物的测定；沉积物有机质和生物基质中的氨基酸分析；天然有机物生物标志物的测定；大气溶解有机氮的分析。这些研究将涵盖基础和应用研究，旨在检验自然科学过程以及人类影响世界的方式。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查进行评估，被认为值得支持标准。
