Argo Germany

ARGO Germany constitutes the German contribution to the global network of profiling floats which was initiated in 2000. The target of the international ARGO programme is a data coverage of 1 float per 3x3° grid cell and month over the global ocean. At present 182 German floats contribute to the international programme.

ARGO floats measure temperature and salinity from approx. 2000 m depth to the surface every 10-15 days. Preliminarily quality controlled data are freely available within 24 h to everybody and highly quality controlled data are issued usually after 6 month as part of the ‚delayed mode‘ data stream.

Data from the ARGO network support the enhanced real-time requirements of operational modelling applications in oceanography and meteorology and provide essential information to monitor climate change in the mers & oceans.

ARGO Germany is operated by the Bundesamt fuer Seeschiffffahrt und Hydrographie (BSH) with financial support from the Federal Ministry of Transport, Building and Urban Affairs.

Goal

The primary goal of the ARGO program is to maintain a global array of autonomous profiling floats as part of a global climate observing system and to serve the data requirements of the operational modelling community.

The specific aims are to:

Recent deployments

In April 2011 five Argo floats have been deployed in the Atlantic after the 342nd cruise of the fisheries research vessel Walther Herwig III. The scientific crew under chief scientist Dr. Reinhold Hanel from Institute of Fisheries Ecology studied during this cruise the reproduction biology of the European eel in the central Sargasso Sea. The following two week crossing from Bermuda to Bremerhaven was used to conduct further studies on possible drift routes of the eel larvae in the Gulf Stream and the North Atlantic Current towards European coasts. In addition, BSH used the crossing to deploy five floats in the Atlantic. The map below shows the deployment locations.
