The effects of animal-sediment interactions on biogeochemical processes at the sediment-water interface

沉积矿床中的成岩作用在生物地球化学反应元素的循环和埋藏中起着核心作用。海洋底栖生物的活动极大地影响了早期成岩作用，改变了表层沉积物中的物质运输和反应分布，以及微米到厘米级的沉积物-水交换。在这个项目中，纽约州立大学石溪分校的研究人员将继续开发和使用创新的透明传感器薄膜，以跟踪与O2、Mn、N、Fe、S和C相关的现场氧化还原反应，测量胞外酶活性，并量化碳酸盐溶解，以推进对生物成因对生物地球化学循环的影响的预测性、机械性理解。这项研究的结果将促进对生物地球化学过程的基本理解。广泛的影响：该项目将为高中、本科生和研究生提供科学培训，包括来自不同代表性不足群体的学生。这项研究的结果将与其他科学家和公众分享，增加对海底过程的了解。

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.
