As Argos users, manufacturers or potential users you’re welcome to attend this regional Argos workshop on bird tracking. The objectives of this Scientific and Technical meeting are:
- Provide a forum for bird trackers and Argos representative,
- Inform on Argos and future capabilities,
- Share experiences and knowledge with Argos for bird tracking,
- Communicate on new Argos services and bird transmitters available.

International Argo program: A revolution in climate research
The oceans play a central role in the earth’s climate. Yet continuous observations of the ocean are difficult to obtain, especially below the sea surface, which is why the international Argo program is so important to climate research.

Find a tag at sea with goniometer
“…the goniometer worked perfectly for chasing down PSATs on their pop-up date in Glacier Bay! We were able to recover 4/5 tags that popped up, including 1 Desert Star tag that was missing an antenna! The remaining tag is another Desert Star tag that is not transmitting frequently enough to provide an Argos location, it is possible that this tag is missing its antenna as well….”

Finding a glider in the Coral Sea
A glider deployed in the Coral Sea in May 2015 by the IMOS (Australia) developed technical problems, most likely due to a faulty memory card. The glider was recovered in September 2015, thanks the RXG-134.”
Exploring the possibility of using Argo float data to validate bathymetric data
Ocean bathymetry is one of the major factors which control dynamic processes such as oceanic currents, coastal upwelling, tides, tsunamis, and internal waves. Bathymetric datasets also form a major input for ocean models. Accurate water depth information is necessary when studying ocean dynamics. A variety of bathymetric datasets with different coverages, resolutions, and accuracies are now available. While the quality and resolution of such datasets have improved greatly for open oceans as satellite-altimetry data become available in the late 1990s, large uncertainties still remain for bathymetries in shallow waters where the spatial scale of bottom features are small. Further refinement of bathymetric datasets for shallow regions is necessary to improve the overall performance of ocean models. Argo float data may provide a new source for validating these data, as Udaya Bhaskar explains.
An Argos tag floated about 3,000 kilometers before being found in Ireland
By combining the data acquired with their location, Argos enables biologists to improve their understanding of the Salmon fish behavior, such as their movements, foraging strategies, reproduction and the way they adapt to their surrounding environment.
