Description:
During the SOPRAN cruise Maria S. Merian 18/3 in July 2011a Lagrangian surface drifter was deployed at four different stations in the eastern equatorial Atlantic during the peak of the equatorial upwelling season. The drifter was equipped with a sensor package measuring temperature, salinity, pCO2, O2, nitrate, fluorescence and gas tension in approximately 15 m depth at 1-minute intervals. During each 24-h deployment of the drifter accompanying CTD casts were conducted every four hours and additional parameters were sampled (Dissolved Inorganic Carbon, Alkalinity, Dissolved and Particular Organic Carbon, nutrients, Chlorophyll, O2). Here we present first data of the drift experiment, indicating diel variability of various biogeochemical parameters. The observations prove the drifter to be a powerful tool to observe diel cycles.
