The Effects of Animal-Sediment Interactions on Geochemical Processes Near the Sediment-Water Interface

这项研究的目的是研究生物对沉积物的洞穴形成和改造如何影响这些沉积物中化学反应的速率和程度。特别是P.I.将研究这些参数对元素锰、氮和碳的化学行为的影响。该项目的最终目标是：1)对早期成岩作用中发生的搬运和反应分布类型进行定量描述（使用一个或多个数学模型）；2)更好地了解搬运和分布对沉积物的地球化学和生态的影响。

It is the purpose of the proposed research to examine how the creation of burrows and reworking of the sediment by organisms effects the rate and degree of chemical reactions within these sediments. In particular the P.I. will study the effects of these parameters on the chemical behavior of the elements manganese, nitrogen and carbon. The eventual goals of the project are: 1) to create quantitative descriptions (using a mathematical model or models) of the types of transport and reaction distribution occurring during early diagenesis, and 2) to understand better the implications of the transports and distributions on the geochemistry and ecology of the sediments.
