The BP Deepwater Horizon oil spill in 2010 was a major environmental disaster. My laboratory received RAPID funding from NSF to conduct a study of how oil affected salt marsh food webs, with an emphasis on arthropod food webs (insects and spiders). I also participated wiht the NOAA team in reviewing oil spill effects on benthic invertebrates. We've published several manuscripts based on this work.
