Which of the following is NOT a MARPOL special area?

The Pacific Ocean is not designated as a MARPOL special area, which is crucial for understanding the regulations governing marine pollution. MARPOL, or the International Convention for the Prevention of Pollution from Ships, defines certain regions known as 'special areas' where stricter controls apply to prevent pollution from ships. These areas are generally located in seas with particularly vulnerable marine environments and high levels of maritime activity.

The Mediterranean Sea, the North Sea, and the Baltic Sea are all special areas under MARPOL because they are significant ecosystems that require additional protections due to their susceptibility to pollution. These regions experience heavy shipping traffic and face various environmental risks, necessitating enhanced measures to minimize pollution from ships, such as limitations on discharges of oil, sewage, and other harmful substances.

In contrast, while the Pacific Ocean is vast and contains numerous marine ecosystems, it does not fall into the category of a MARPOL special area. Therefore, ships navigating the Pacific Ocean are subject to standard MARPOL regulations rather than the heightened protections required in designated special areas. This distinction is critical for ensuring that shipping practices are adjusted according to the environmental sensitivities of different maritime regions.
