Diagenetic processes in sedimentary deposits play a central role in the cycling and burial of biogeochemically reactive elements. The activities of marine benthos dramatically impact early diagenesis, altering material transport and reaction distributions in surface sediments and sediment-water exchange on scales of microns to centimeters. In this project, researchers at SUNY Stony Brook will continue to develop and use innovative transparent sensor foils to track in situ redox reactions associated with O2, Mn, N, Fe, S, and C, measure exoenzyme activity, and quantify carbonate dissolution to advance predictive, mechanistic-based understanding of biogenic effects on biogeochemical cycles. Results from this study will advance fundamental understanding of biogeochemical processes.Broader Impacts: This project will provide scientific training to high school, undergraduate, and graduate students, including those from a diversity of underrepresented groups. Results from this study will be shared with fellow scientists and the general public, increasing knowledge about the seafloor processes.

沉积沉积物中的成岩化过程在生物地球化学反应性元素的骑自行车和埋葬中起着核心作用。海洋底栖生物的活性极大地影响了早期成岩作用，改变了微米尺度上的表面沉积物和沉积物 - 水交换中的材料转运和反应分布。在这个项目中，SUNY Stony Brook的研究人员将继续开发和使用创新的透明传感器箔，以跟踪与O2，MN，MN，MN，N，FE，S和C相关的原位氧化还原反应，测量外酶活性，并量化碳酸盐溶解以提高预测性，基于机械机械性的对生物质量cyceles的生物基因效应。这项研究的结果将提高对生物地球化学过程的基本理解。BOADER的影响：该项目将为高中，本科生和研究生提供科学培训，包括来自代表性不足的群体的多样性。这项研究的结果将与科学家和公众共享，越来越多地了解海底过程。
