Qualitative Assessment of the Anthropogenic CO sub 2 Distribution in the Southern Ocean

摘要

Contour diagrams showing the penetration of anthropogenic CO sub 2 are given for selected cross-sections of the Southern Ocean based on the GEOSECS and IGY data. The excess CO sub 2 has generally penetrated rather deeply near the Polar Front, and even deeper further north. South of the Polar Front the excess CO sub 2 penetrates no more than 500 m deep and frequently only to 200 m. On the continental shelf the man-made CO sub 2 exists throughout the water column.
