ABSTRACT:
A method and apparatus are provided for containing and collecting oil spilled under ice over water having a current by deploying a buoyant boom or barrier under the ice downstream of the oil spill and crossing the current flow, and stopping the flow of the oil with the boom or barrier. Preferably, the boom or barrier is constructed of two tubes connected by a spreader which are inflatable in situ under the ice and which form a water space above the spreader and between the tubes which subsequently freezes to anchor the boom or barrier in place.
