ABSTRACT:
The method is for treating a marine object. A composition is provided that has an organic substance. The composition is applied to the marine object. The composition has a first layer and a second layer. A first organic substance on the first layer attracts bacteria. The bacteria consume the first organic substance and during this process use oxygen. The bacteria thus reduce an oxygen level in a boundary layer adjacent to a surface of the marine object. The first layer of the composition erodes to expose the second layer. The bacteria consume a second organic substance of the second layer.
