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

沉积中的成岩作用在生物地球化学活性元素的旋回和埋藏中起着核心作用。海洋底栖生物的活动显著影响了早期成岩作用，改变了表层沉积物中的物质迁移和反应分布以及微米至厘米尺度上的沉积物-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来跟踪与O2、Mn、N、Fe、S和C相关的原位氧化还原反应，测量外显酶活性，量化碳酸盐溶解，以推进对生物地球化学循环生物成因效应的预测和基于机械的理解。本研究结果将促进对生物地球化学过程的基本认识。更广泛的影响：该项目将为高中生、本科生和研究生提供科学培训，包括来自各种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.
