Crude Petroleum in Northwest Florida Beach Sand, Santa Rosa and Escambia Counties in Florida, 5-3-2010 to 4-4-2011.

Samples of surf zone beach sand were collected to track the occurrence and degradation of alkane hydrocarbons on beaches of the West Florida Panhandle. Composite samples were air dried and extracted by standard procedures for analysis of alkanes found in the BP MC 252 well oil by GC. Alkanes were only found after beach oiling, and rapidly decreased to background levels.

为追踪佛罗里达西北狭长地带海滩上烷烃类物质的赋存与降解过程，研究人员采集了滨岸带海滩沙样品。
复合样品经风干处理后，按照标准分析流程进行萃取，以通过气相色谱（Gas Chromatography）分析英国石油（BP）MC 252井原油中的烷烃类组分。
仅在海滩发生溢油后才可检测到烷烃类物质，且其浓度会快速降低至本底水平。
