View the floats in Google Earth
Argo has over 3000 active floats. We have selected a few that we think are particularly interesting because of what they tell you about the ocean. For each float we have collected background information to help you interpret the float data.
If you have Google Earth installed on your computer, you can view our float selection using this link: Selected Argo Floats*. If not, go to the Google Earth website to download and install the software.
* Note: Some browsers will not open Google Earth 'on-the-fly', so you may have to save the file first and then open it in Google Earth.
Our selection represent only a small fraction of the total number of active Argo floats. If you wish, you can view the entire fleet of active floats in Google Earth simply by downloading the status.kmz file from the Argo Information Centre.
As you can see from the screenshot on the right, there are a large number of floats in the Atlantic. Zoom in and you will see that the floats tend to collect in some areas, while other regions have far fewer floats.
Each of the selected floats is represented by a small picure of a yellow Argo float. Clicking on a float gives you a 'baloon pop-up' with
- information about the float,
- thumbnail plots of the float data, and
- links to larger plots and hints on how to interpret the data.
You can also see where the floats have been by clicking on the "Float tracks since launch" box (see figure 1a). To select a single float track, open the the folder "Float tracks since launch" (see figure 1a) and check the box next to the number of the float you want. The number of individual floats can be found on the float balloon (figure 2).
Below is a list of other data for Google Earth, which may help you interpret the float data, and see the information the floats provide in a wider context.
- Ocean Currents and Sea Surface Temperature This data set contains arrows indicating the main ocan currents overlaid on a map of sea surface temperature (SST) from all available satellite data. The map, provided by the UK Met Office OSTIA project, is updated daily in near realtime.
