I was watching Catalyst on ABC TV and learned about these cool robots that monitor the conditions at the bottom of the world's oceans. They're called Argo floats and the transcript from the Catalyst website explains them thus -"Humans have been weather forecasting for thousands of years. But the ocean also plays a huge role in our climate patterns and until now the processes that go on beneath the surface have been largely a mystery. But that mystery is being slowly revealed. Ten years ago Australia released the first Argo floats into the Indian Ocean. These nautical robots dive up to two kilometres every ten days and surface to transmit their precious measurements to Argo headquarters. Twenty countries maintain the global armada of more than 3000 Argo floats... and they're providing oceanographers with an unprecedented wealth of data from deep beneath the sea."
Isn't technology wonderful?
