When a marine heat wave strikes, scientists often turn to satellites to see how the ocean is responding. From space, changes in ocean color can reveal shifts in phytoplankton, microscopic organisms that form the foundation of marine food webs and play a crucial role in the global

When a marine heat wave strikes, scientists often turn to satellites to see how the ocean is responding. From space, changes in ocean color can reveal shifts in phytoplankton, microscopic organisms that form the foundation of marine food webs and play a crucial role in the global carbon cycle. But satellites have a fundamental limitation: they can only see the ocean's surface.

Measuring deep-ocean oxygen with microscopic magnetic fossils

Humanity's ongoing disruption of atmospheric carbon dioxide (CO₂) concentrations, temperatures, and global nutrient cycles is starving the oceans of oxygen. Although we can measure ongoing changes to ocean circulation and marine life, we still don't know how far the oxygen loss a
