Argo reaches its goal of 3000 active floats!

During the month of October 2007, over 100 floats were deployed by various Argo scientists around the world to reach 3000 active Argo floats. Since we cannot tell exactly which float was the 3000th, float deployers were invited to submit photos of "Argo_3000" float candidates. Below are the winning Argo_3000 photos (starting with the most recent).

Scroll down the page to see all the contributions.


The 3000th active Argo float (perhaps) is a Canadian Argo_3000 float being launched in the Bering Sea at 58°N and 175°W on 27 October, 2007 by JAMSTEC personnel from the RV Mirai

the Argo_3000 float just after the photo was taken in mid-October 2007
The photo to the left shows a University of Washington Argo_3000 float (equipped with ice-detection software) just before deployment in the Indian Ocean sector of the Southern Ocean. The float was deployed near 100° E, 65° S during a cruise of the Australian icebreaker, Aurora Australis. The ship can be seen in the background of the photo. It is early spring, and the seasonal ice in the region has not yet melted. In order to deploy the float, a hole is drilled in the ice (approximately 1.5 meters thick) and the float is then lowered into the hole. 24 University of Washington floats were deployed in this fashion during the Aurora Australis cruise. The floats can store profiles collected while under the ice and transmit all of the data during austral summer, after the ice has melted. We hope to hear from this float and the others deployed on this cruise early in 2008. The University of Washington Argo float group extends its thanks to the officers, scientists and crew of the Aurora Australis for carrying out these challenging float deployments.
