A Hanover, N.H., firefighter takes advantage of a unique opportunity to extinguish burning North Slope crude oil. The burning is part of Alaska Clean Seas’ Advanced oil Response in Ice course, program to train oil spill responders. The fire department’s presence was requested as a precaution, but resulted in training for them as well. Burning oil is an environmentally accepted and extremely efficient method of mitigating oil spills in ice-infested water.
