Earth’s wobble ‘fixes’ dinner for marine organisms

The cyclic wobble of the Earth on its axis controls the production of a nutrient essential to the health of the ocean, according to a new study in the journal Nature. The discovery of factors that control this nutrient, known as «fixed» nitrogen, gives researchers insight into how the ocean regulates its own life-support system, which in turn affects the Earth’s climate and the size of marine fisheries.
