Research Investigations into Herder Fate, Effects and Windows-of-opportunity

In-situ burning (ISB) offers an effective spill response tool in a variety of ice concentrations. The key to effective ISB is thick oil slicks. In low ice concentrations oil on water can rapidly spread to become too thin to ignite. The focus of herder research for Arctic oil spill response has therefore been on their application in drift ice conditions (1 to 6 tenths ice cover) in which slicks can spread fairly rapidly. The objective of this multi-project and interdisciplinary research programme was to advance the knowledge of herder environmental fate, effects and performance to expand the operational utility and environmental assessment of ISB in open water and in ice-affected waters with drift ice conditions. The final project report “Research Investigations into Herder Fate, Effects and Windows-Of-Opportunity” summarises results from experiments laboratory and tank tests that were conducted.
