The Funds will be used to drill two holes into platform carbonates on the Great Bahama Bank. This drilling will take place from a jack-up platform situated in 5 to 10 m of water on the platform margin and interior and will penetrate between 500 and 1000 m of sediments. The rationale for drilling these holes is two fold. First, recent discoveries about the subsurface, Neogene, seismic stratigraphy of Great Bahama Bank have drastically changed long standing ideas concerning the evolution of the Bahamas. Drilling will provide a test of these ideas as well as examining relationships between pulses of progradation and relative fluctuations of sea level. Second, drilling the holes will allow an unique opportunity to examine the chemistry of formation fluids from deep within the platform which will provide an indication of the diagenetic reactions taking place.

这些资金将用于钻两个洞， 大巴哈马浅滩的台地碳酸盐岩这次钻探将 从位于5至10米水深的自升式平台进行 在平台边缘和内部， 500和1000米的沉积物。钻这些的基本原理 孔是两个折叠。首先，最近的发现 地下，新近纪，大巴哈马浅滩地震地层学 彻底改变了人们长期以来对 巴哈马群岛的演变钻探将提供一个测试， 这些想法以及检查脉冲之间的关系 以及海平面的相对波动。 其次，钻这些洞将提供一个独特的机会， 研究地层流体的化学成分， 平台，这将提供成岩的指示 反应正在发生。
