Aerial Application of Herding Agents can Enhance In-Situ Burning in Partial Ice Cover

ABSTRACT In situ burning (ISB) aided by herding agents is a promising tool for oil spill response in Arctic waters. An advantageous aspect of the herder mediated ISB approach is that the application of herders as well as the subsequent ignition of the slick could potentially be carried out from aerial platforms. This could obviate the need for personnel to conduct operations on the surface near the burn, as well as reduce the response time required to mobilize the spill response equipment, especially in challenging Arctic conditions. In the last decade, several laboratory and field-scale tests have been conducted to prove the efficacy of herder-assisted ISB operations, sometimes achieving burn efficiencies greater than 90 %. However, there have been no field tests of aerial herder application followed by ignition. This paper presents results from a series of field experiments performed in a custom-built test basin 50 km northeast of Fairbanks, Alaska, in April 2015. A helicopter was employed to first appl...
