Trajectory Data

In addition to the measurements of water properties, Argo floats also drift with the currents, giving us lagrangian velocity information. The plot below shows the trajectory of an Argo float that was initially deployed south of Tasmania in the Southern Ocean. This float has drifted at 1000 m depth for six years (2051 days) with the Antarctic Circumpolar Current and is currently approaching Drake Passage. It probably won't last long enough to complete a circumnavigation of Antarctica but we will watch its progress with interest!
