Abstract

Water column data of carbon and carbon-relevant parameters have been collected and merged into
a new database called CARINA (CARbon IN the Atlantic). In order to provide a consistent data set, all data
have been examined for systematic biases and adjusted if necessary (secondary quality control (QC)). The
CARINA data set is divided into three regions: the Arctic/Nordic Seas, the Atlantic region and the Southern
Ocean. Here we present the CFC data for the Atlantic region, including the chlorofluorocarbons CFC-11,
CFC-12 and CFC-113 as well as carbon tetrachloride (CCl4). The methods applied for the secondary quality
control, a crossover analyses, the investigation of CFC ratios in the ocean and the CFC surface saturation are
presented. Based on the results, the CFC data of some cruises are adjusted by a certain factor or given a “poor”
quality flag.
