Antarctic bottom waters freshening at unexpected rate

In the cold depths along the sea floor, Antarctic Bottom Waters are part of a global circulatory system, supplying oxygen-, carbon- and nutrient-rich waters to the world's oceans. Over the last decade, scientists have been monitoring changes in these waters. But a new study suggests these changes are themselves shifting in unexpected ways, with potentially significant consequences for the ocean and climate.
