“Crude Oil Effects on Redox Status of Salt Marsh Soil in Louisiana” with Dr. John White. Also featuring Dr. John Pardue.

Ten years ago, on April 20th, the Deepwater Horizon oil platform exploded, killing eleven crewmen and releasing about five million barrels of crude oil into the Gulf of Mexico and surrounding environment over the next 87 days. Drs. John White and John Pardue have spent much of their careers focusing on the effects of oil on the environment and ways to speed recovery efforts after spills. Join us as we discuss their papers on the relationships between oil, plant health, and microbes, as well as where we are on the road to recovery today.

Listen in to learn:

  • The difference between fresh and weathered oil
  • How buried and surface level oil can affect the health of plants
  • The importance of oxygen for microbial breakdown of crude oil
  • Where we are today in the recovery process after Deepwater Horizon

If you would like more information about this topic, this episode’s paper is available here: 

It will be freely available from 3 April to 17 April, 2020.
