 ards a more predictive understanding of the sunlight-driven weathering of 
 oil spilled at sea.\n\n \n\nAbstract: \n\nPhotochemical oxidation (photo-o
 xidation) of crude oil spilled at sea has been studied for over half a cen
 tury. However\, prior to the 2010 Deepwater Horizon oil spill\, photo-oxid
 ation was widely considered a secondary weathering process that impacted a
  small fraction of spilled oil. Accordingly\, photo-oxidation was not incl
 uded in oil spill fate and trajectory models and response operations. In t
 his talk\, I’ll describe several key findings related to the rates\, pathw
 ays\, controls\, and impacts of crude oil photo-oxidation during the Deepw
 ater Horizon spill. These findings have collectively changed the perspecti
 ve of photochemical weathering in the oil spill sciences\, leading to its 
 inclusion in oil spill models and increased consideration during response 
 operations. I’ll conclude with a discussion about the role sunlight may pl
 ay during future oil spills\, including spills in colder\, high-latitude w
 aters where risks are increasing because of global climate change. \n
