Members of Alaska Chadux Corporation monitor a Beach Deluge Response System during an oil spill equipment deployment demonstration during the Operation Arctic Guardian seminar held at the beach near the borough’s fuel supply in Utqiaġvik, Alaska, July 27, 2017. The response system is used to clean up fuel spills onshore by flooding the beach causing fuel to raise to the surface and subsequently skimmers and absorbent products are used to complete cleanup.
