Abstract
This talk presents the findings on the temporal changes in the euphausiid assemblage following the Deepwater Horizon oil spill (DWHOS). This is the first multi-year study on euphausiids that includes depths down to 1000 m, as part of two sampling programs in this region. This analysis demonstrates that there was a massive decline in the assemblage abundance between 2011, 1 year after the spill, and 2015 - 2017, 5-7 years after the spill. As there are no data on the euphausiid assemblage from this region prior to the oil, the cause of this decline cannot be directly attributed to the oi spill, and further sampling is needed to determine if this is a persistent decline caused by the oil spill, rather than natural variability.
