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
Tethys Ocean Western Tethys Ocean, or Paratethys or Alpine Tethys Ocean. The Black, Caspian, and Aral seas are thought to be its crustal remains, though the Black Sea may, in fact, be a remnant of the older Paleo-Tethys Ocean. The Western Tethys was not simply a single open ocean. It covered many small plates, Cretaceous island arcs, and microcontinents. Many small oceanic basins (Valais Ocean, Piemont-Liguria Ocean, Meliata Ocean) were separated from each other by continental terranes on the Alboran, Iberian, and Apulian plates. The high sea level in the Mesozoic flooded most of these continental domains, forming shallow seas. As theories
