31.01.2019 Oceanography and meteorological applications Measuring CO2 in faraway regions of the ocean

The ocean is one of the most important carbon sinks on Earth. Thus, accurate estimation of CO2 uptake by the ocean is important for predicting global climate change. Automated buoys with data collected by Argos satellite telemetry make it possible to measure CO2 over the whole ocean during long periods,…

24.01.2019 Flash news Argos system contributes to Argo program milestone

Last month, the international Argo program reached a very important milestone: Over 2 million ocean profiles have been collected by Argo since 1999, greatly improving the understanding of the world’s oceans. The Argos satellite telemetry system has contributed to this success, by relaying 70% (1.5 million) of these precious ocean…
