摘要

Samples collected on the first four of six cruises to the U.S. Mid-Atlantic as part of a study to evaluate potential effects of drilling have been analyzed for benthic infauna, hydrocarbons, sediment grain size, and total organic carbon, hydrogen and nitrogen. There is no evidence that the hydrocarbons in the sediments originate from sources associated with drilling activities. A very subtle change in the fauna at the drill site station in Block 372 was detected. Species diversity declined at Station 1 over time, but this trend is not statistically significant. The density of at least one dominant species was significantly lower in post-drilling samples compared to pre-drilling samples, but the density of the species was not significantly different at Station 1 compared to the majority of 2100 m stations for any sampling period.
