Ocean Conveyer in the news

The ice caps are melting, and we are all still probably doomed.  But the textbook version of the Great Ocean Conveyer may need some fine-tuning.  The release of floats in the deep Atlantic counter current (below the Gulf Stream) shows that this water may not move as predicted.  The new understanding of this current will lead to revised models for Conveyer flow and its effects on global climate.

And remember DDT, the once popular insecticide banned in the 1970 due to its propensity to thin bird egg shells and other various toxic effects.  Apparently lots of it was sucked down into the conveyer, and it is now slowly being released back into the atmosphere.
