项目摘要
ABSTRACTOCE-0136597Recently, it has been suggested that oxygen transport into sediments via the roots and rhizomes of seagrasses might resolve the observed discrepancy between the amount of carbonate dissolved and the amount of acid produced from remineralization of sediment organic matter. Combining field observations, laboratory experiments and modeling analysis, a PI from Old Dominion University will team up with a PI from San Jose State University to quantify the influence of seagrass productivity on carbon flux and carbonate dissolution in shallow waters of Lee Stocking Island, Bahamas, a tropical system. The PIs will compare the sediment and porewater composition recovered from a variety of sample types (bare ooid sands to densely vegetates regions with 70% seagrass cover) to establish the relationship between carbonate dissolution in sediments and seagrass density. Other studies to be carried out include incubation experiments of individual seagrass shoots to determine the amount of O2 generated by the roots and rhizomes under variable light and porewater O2 conditions. Additionally, whole sediment core incubation experiments will determine the rate of sediment organic matter degradation and carbonate dissolution. Lastly, Drs. Burdige and Zimmerman plan to compare their data with those obtained via a model of diagenetic processes in carbonate sediments. Results from this study will not only provide basic information on ecological and biogeochemical processes in tropical systems, but will help constrain budgets for carbonate cycling in shallow water carbonate bank environments.
最近,有人提出,通过海草的根和根茎将氧输送到沉积物中可能解决所观察到的溶解的碳酸盐的量与沉积物有机物的矿化所产生的酸的量之间的差异。 结合实地观察,实验室实验和建模分析,来自旧自治领大学的PI将与来自圣何塞州立大学的PI合作,量化海草生产力对巴哈马Lee Stocking岛(一个热带系统)浅水沃茨碳通量和碳酸盐溶解的影响。 PI将比较从各种样品类型(裸卵砂到海草覆盖率为70%的密集植被区)中回收的沉积物和孔隙水成分,以确定沉积物中碳酸盐溶解与海草密度之间的关系。 将要进行的其他研究包括个别海草苗的孵化实验,以确定在可变的光照和孔隙水O2条件下根和根茎产生的O2量。 此外,整个沉积物岩心培养实验将确定沉积物有机物降解和碳酸盐溶解的速度。 最后,Burdige和齐默尔曼博士计划将他们的数据与通过碳酸盐沉积物成岩过程模型获得的数据进行比较。 这项研究的结果将不仅提供在热带系统的生态和地球化学过程的基本信息,但将有助于限制预算碳酸盐循环浅水碳酸盐银行环境。
