To enable integration of ecosystem and individual environmental assets into one set of ocean asset accounts, the GOAP Technical Guidance combines both types of assets in three physical asset accounts tables: physical asset extent accounts (Table 6), physical asset condition accounts (using biophysical variables) (Table 7) and summary asset condition accounts (using condition indicators) (Table 8). These are the accounts tables that the Global Ocean Asset Data Inventory and Guide aim to inform.
Table 6: Physical asset extent account. (Example table, could be expanded to include several different ecosystem assets and individual environmental assets.)

Notes: Darkly shaded areas represent undefined measures for ecosystem assets (extractions/harvesting) and expansion of minerals stocks. Terminology still requires harmonization between SEEA CF and SEEA EA. For example, extraction/harvesting refers to individual environmental assets in the SEEA CF. Ecosystem assets are treated in the SEEA EA like land cover types, which are added to and reduced by area through managed/natural expansion/regression.
