Pollution in the Arctic Ocean cleaner sulphur-based fuel could resolve the issue. Pollution in the Arctic Ocean Pollution in the Arctic Ocean is primarily the result of economic activities carried out on land – such as industrial development in the Arctic region, northern rivers, and the effects of military activities, particularly nuclear activity – as well as the influx of pollutants from other regions of the world. However, the Arctic Ocean remains relatively clean compared to other marine regions of the world. Economic activity in the Arctic seas is not the only source of pollution. The growing presence of military weapons systems in the region
Beaufort scale winds in hurricanes would be 23 in the scale. Today, hurricane-force winds are sometimes described as Beaufort scale 12 through 16, very roughly related to the respective category speeds of the Saffir–Simpson hurricane scale, by which actual hurricanes are measured, where Category 1 is equivalent to Beaufort 12. However, the extended Beaufort numbers above 13 do not match the Saffir–Simpson scale. Category 1 tornadoes on the Fujita and TORRO scales also begin roughly at the end of level 12 of the Beaufort scale, but are independent scales – although the TORRO scale wind values are based on the 3/2 power
