英文摘要	Greatly enhanced atmospheric carbon dioxide (CO 2 ) levels relative to well-mixed marine air are observed during periods of offshore winds at coastal sensor platforms in Monterey Bay, California, USA. The highest concentrations originate from urban and agricultural areas, are driven by diurnal winds, and peak in the early morning. These enhanced atmospheric levels can be detected across a ~100km wide nearshore area and represent a significant addition to total oceanic CO 2 uptake. A global estimate puts the added sea-air flux of CO 2 from these greatly enhanced atmospheric CO 2 levels at 25 million tonnes, roughly 1% of the ocean’s annual CO 2 uptake. The increased uptake over the 100 km coastal swath is of order 20%, indicating a potentially large impact on ocean acidification in productive coastal waters. Northcott et al.
