North Pacific dead zone may grow smaller, not expand, as climate change weakens Pacific Ocean trade winds.

Oceans

Mercury at ocean surface may have tripled since preindustrial times

Questions remain over dangers of toxic metal in environment.

Whales and ships don’t mix well

A 15-year study of blue whales off California has found that major shipping lanes cut through feeding grounds.
