It is increasingly recognized that air-sea CO2 flux and carbon budget in continental margins represent an important knowledge gap in global carbon cycling research.In the east coast of the North America,until very recently,the US Mid-Atlanta Bight is the only shelf that annual air-sea CO2 flux was measured (by Takahashi,DeGrandpre et al.).While this shelf acts as a moderate-to-strong sink of atmospheric CO2,its overall carbon flux to the open ocean is not known.The central part of the South Atlantic Bight (SAB) was reported as a source of CO2 to the atmosphere as a result of decomposition of organic matter exported from rivers and the productive salt marshes.

Micrometeorological methods are expected as crucial for the direct measurement of air-ocean exchange of carbon dioxide (CO2).The profile method is plain and simple compared with the eddy-covariance me
