Cutoff switch may limit spread, duration of oxygen minimum zones

A new study examining the impact of iron released from continental margin sediments has documented a natural limiting switch that may keep these ocean systems from developing a runaway feedback loop that could lead to unchecked ...

Scientists solve a 14,000-year-old ocean mystery
