When the scope of ocean sector activities is broadened to include spin-off impacts (indirect and induced activities), the relative importance of the ocean sector increases to 1.9% of national GDP and 2.0% of total employment. [...] The strong GDP result is due to the high returns to and of capital flowing from high petroleum prices, while the relatively low employment reflects the capital intensiveness of the industry. [...] Much of the difference between the Pacific and Atlantic in the respective contributions to the national impact is accounted for by the Atlantic offshore oil & gas industry. [...] The methodology goes on to explain the approach used to measure the economic value of the specified marine activities, including the meaning of specific indicators and how direct, indirect and induced impacts are defined. [...] The list includes direct and indirect activities in the private and public sectors that are identified as either primary or secondary according to their relative economic importance and the state of knowledge about the activity (Table 2.1): Primary marine activities: these represent the core of the marine economy; industries deriving their economic rationale in a direct way from their extractive
