Ship-board report on atmospheric CO2 concentrations recorded on continuousfrom Mediterranean Sea to Antarctica

We present the results obtained from continuous measurements performed duri ng two cruises with hemispherical courses. In this way, we obtained the lat itudinal trend of COB in continuity of space and time along two hemispheric courses in 1994-95 and 1996-97 from Europe to Antarctica. The results are compared with measurements from the National Oceanic and Atmospheric Admini stration (NOAA) Climate Monitoring and Diagnostic Laboratory (CMDL) coopera tive air sampling network. The fitting of data recorded on board with the h istorical data sets recorded at Palmer Station is also presented, highlight ing the current annual increase in atmospheric CO2 concentrations.
