The PI plans to core offshore the British Virgin Islands (BVI) on drowned reefs for sealevel change and sea surface temperature records. This will extend the Caribbean record from 20 k.yrs. to 60 k.yrs. and extend the Carbon 14 calibration to 40 k.yrs. BP Wireline coring offshore BVI will also replicate and fill in important gaps in the Barbados records. A lifeboat capable of wireline coring in water depths of up to 100 m and cores of up to 200 m length has been designed and developed with institutional funds. A Plasma 54 mass spectrometer, capable of rapid analyses of elements and isotopes, will be used for decipher the coral record.

该项目计划在英属维尔京群岛（BVI）近海被淹没的珊瑚礁上进行取样，以记录海平面变化和海面温度。这将把加勒比海地区的记录从20公里延长。到60千米。并将碳14校准扩展到40千米/年。BP有线公司在英属维尔京群岛海上取心也将复制并填补巴巴多斯记录的重要空白。利用机构资金设计和开发了一种能够在水深达100米、岩心长度达200米的情况下进行电缆取心的救生艇。一台能够快速分析元素和同位素的等离子54质谱仪将用于破译珊瑚记录。
