摘要: The Deepwater Horizon accident resulted in a substantial uncontrolled hydrocarbon release to the northern Gulf of Mexico, much which was entrained deep submerged plumes. While bio-degradation hydrocarbons has been inferred from microbial biomass and genetics, amount conversion oil gas carbon remains uncertain having only estimated modeling studies. Here we examine correlated depletions nitrate, phosphate oxygen plumes conclude that portion these converted (0.8?2???1010?mol C). This contrasts with nutrient-limited surface waters where other work suggested hydrocarbon-induced growth have minimal. Our results suggest need for better monitoring changes nutrients as well study nutrient recycling similar future releases.
