3000th Argo Ocean Probe Launch

The 3000th Argo ocean sensor probe is to be launched from the RV Kaharoa off New Zealand.

The Argo program started in 2004 collects temperature, salinity and pressure readings from all of the worlds oceans with the 3000 sensor probes.

The robot sensors sink in the water to a depth of up to 2000 meters. When they reach the target depth they pump oil into an external bladder to allow them to float to the surface. As they rise they record the temperature and salinity readings. At the surface they transmit their position and data to a satellite then begin the cycle again. Each cycle takes about ten days.

The objectives of the Argo project are to get a better understanding of the oceans and the world's climate. The program has worldwide support.

Each probe is expected to last about 150 measurement cycles and they plan to replace 800 per year.
That is a lot of robots. Do not be surprised if one of the floats up in your bathtub one day.
