NewsWeaker ocean currents lead to decline in nutrients for North Atlantic ocean life during prehistoric climate change
Researchers at Georgia Institute of Technology have finished investigating how the prehistoric weakening of a major ocean current led to a decline in ocean nutrients and negative impacts on North Atlantic ocean life. The results support predictions about how our oceans might react to a changing climate — and what ...
