英文摘要:
The lateral and vertical extents of Macondo oil in deep-sea sediments resulting from the 2010 Deepwater Horizon oil spill were determined using chemical forensics and geostatistical kriging of data from 2397 sediment samples from 875 cores collected in 2010/2011 and 2014. The total mass of Macondo-derived hopane on the seafloor in 2010/2011 was conservatively estimated between 2.00 and 2.26�metric tons, derived from 219,000 to 247,000�barrels of oil; or 6.9 to 7.7% of the 3.19�million�barrels spilled. Macondo-derived hopane was deposited over 1030 to 1910�km2of the seafloor, mostly (>�97%) in surface (0–1�cm) and near-surface (1–3�cm) sediments, which is consistent with short-term oil deposition. Although Macondo oil was still present in surface sediments in 2014, the total mass of Macondo-derived hopane was significantly lower (~�80 to 90%) than in 2010/2011, affirming an acute impact from the spill and not long-term deposition from natural seeps. � 2016 Elsevier Ltd
