摘要

A very small scale (1 m~2) preliminary assessment of a shoreline-cleaning agent with oil herding properties was carried out to assess its ability to herd oil on cold water and among ice. The results were promising: 1. Using the shoreline cleaner on cold water (2℃) greatly reduced the area of sheens of fluid oils, but the thickness of the herded oil was only in the 1-mm range. 2. On thicker (ca. 1 mm) slicks, the shoreline cleaner effect was much more promising and could herd slicks to thicknesses of 2 to 4 mm. 3. Although the presence of ice forms in the pans slightly retarded the effectiveness of the herding agent, it still considerably thickened oil among ice. 4. The composition of the oil appeared to play a strong role in determining potential efficacy: Gelled oils that did not spread on cold water could not be herded. Further tests were carried out to explore the relative effectiveness of three oil-herding agents in simulated ice conditions; conduct larger scale (10 m~2) quiescent pan tests to explore scaling effects; carry out small-scale (2 to 6 m~2) wind/wave tank testing to investigate wind and wave effects on herding efficiency; and, perform small-scale in situ ignition and burn testing. The results from these experiments showed that the application of a herder to thin oil slicks in pack ice has considerable promise for thickening them for in situ burning. One herder formulation proved to be the best suited for the cold conditions. The herded thickness produced by this formulation was consistently in the 3+ mm ranges for 1-L and greater slicks. Oil slicks herded by the chemical were successfully ignited and burned. The burn efficiencies measured were similar to those for physically contained slicks of the same dimensions. The promising results obtained from this and the previous study indicate that further research at larger scales with the herder and oils that are fluid at freezing temperatures is warranted.
