The PIs are acknowledge leaders in the field of marine sediment geochemistry and early digenesis. With this proposal, they plan to continue studies into the activities of bottom- dwelling animals and how they can alter material transport and digenetic reactions in surface sediments of the seafloor. The proposal is divided into three general research areas: a) the irrigation and diffusion structure of solutes in the bioturbated zone, b) the permeability of burrow linings and mucoid secretions, and c) a multi-dimensional study of solute distributions. The proposed development of novel optical fluorosensors to measure small scale variations in pore water chemistry is considered an exciting and important new direction in studies of early digenesis in marine sediments.

PI是海洋沉积物地球化学和早期成岩作用领域公认的领导者。 根据这一提议，他们计划继续研究底栖动物的活动，以及它们如何改变海底表层沉积物中的物质运输和后生反应。 该建议分为三个一般的研究领域：a）在生物扰动区的溶质的灌溉和扩散结构，B）的渗透性的洞穴衬里和粘液分泌物，和c）溶质分布的多维研究。 发展新型光学荧光传感器来测量孔隙水化学的小尺度变化被认为是海洋沉积物早期成岩作用研究中一个令人兴奋和重要的新方向。
