中文摘要
PI先前和正在进行的NSF资助的研究表明, 孔隙水交换碳酸盐颗粒、有机质和海洋 水的范围远比以前想象的要广。 因此,在本发明中, 平台碳酸盐岩可能作为更多有机碳的汇, 由于同位素的储存, 重结晶碳酸盐中的贫碳。 PI要求资金用于 继续她的工作,在寻找沉积物/生物体的关系, 确定化学和微结构沉积参数。 一些工作将继续在佛罗里达湾,但新的研究将开始 在大巴哈马和小巴哈马的银行。
英文摘要
Previous and on-going NSF-funded research by the PI shows that pore-water exchange carbonate particles, organic matter and sea water is far more extensive than previously thought. As a result, platform carbonates may act as a sink for more organic carbon than previously envisioned because of the storage of isotopically- depleted C in recrystallized carbonates. The PI requests funds to continue her work in looking at sediment/organism relations in determining chemical and microstructrual sedimentary parameters. Some work will continue in Florida Bay, but new studies will begin on Great and Little Bahama banks.
