Off the coast of Antarctica, a 4-foot-long, bright yellow tube is drifting through the Southern Ocean and collecting scientific data on the frigid surrounding water.

The device, called a float, will provide researchers at the University of Delaware — and around the world — with valuable information on ocean conditions in this little-monitored region.

The equipment is one of more than 3,600 similar floats bobbing along underwater in oceans worldwide as part of the international Argo program, a data collection and sharing network formed in 1999 to document climate variability and trends. There are relatively few floats in the Southern Ocean, however, and UD's is one of only two there that takes additional measurements beyond the standard salinity, temperature and pressure.
