Sustained deposition of contaminants from the Deepwater Horizon spill
Beizhan Yan,Uta Passow,Jeffrey P. Chanton,Eva-Maria Nöthig,Vernon L. Asper,Julia Sweet,Masha Pitiranggon,Arne R. Diercks,Dorothy K. Pak +8 more
TL;DR: Sedimentation with diatoms accumulated contaminants that were dispersed in the water column and transported them downward, where they were concentrated into the upper centimeters of the seafloor, potentially leading to sustained impact on benthic ecosystems.
Incorporation of oil into diatom aggregates
Uta Passow,Julia Sweet,S. Francis,C. Xu,Anusha L. Dissanayake,YY Lin,Peter H. Santschi,Antonietta Quigg +7 more
TL;DR: The goal was to provide specific input parameters for aggregation models that predict the transport of oil to depth via marine snow-sized aggregates, and found that, contrary to expectations, the sinking velocity of oil-containing aggregates was not decreased, but slightly increased compared to their non-oil-containing counterparts.
Response of natural phytoplankton communities exposed to crude oil and chemical dispersants during a mesocosm experiment.

TL;DR: It is demonstrated that chemically dispersed oil has more negative impacts on photophysiology, phytoplankton community structure and aggregation dynamics than oil alone, with potential implications for export processes that affect the distribution and turnover of carbon and oil in the water column.

TL;DR: In this paper, the authors measured Δ14C, δ13C and δ34S of sinking particles near the spill site and at a reference site and natural seep site.
Evaluating Carbonate System Algorithms in a Nearshore System: Does Total Alkalinity Matter?
TL;DR: The autonomous measurement of pH and salinity can be used to monitor trends in coastal changes in DIC and saturation state and be a useful method for high-frequency, long-term monitoring of ocean acidification.
