The first sample for Argon-39 measurements using the new ATTA method, collected at a depth of 4,000 metres. The sample was obtained during a pilot study in the tropical North Atlantic off the Cape Verde Islands.

Sources and sinks of carbon dioxide in the atmosphere. Due to anthropogenic activities, more carbon dioxide enters the atmosphere than can be bound in the ocean or other natural sinks. In order to calculate the global carbon budget, data on the carbon dioxide uptake of the ocean are necessary. The GEOMAR contributes to this with long-term measurement series.
