Deep-Ocean Oxygen Measured Using Microscopic Magnetic Fossils
Original: Measuring Deep-Ocean Oxygen with Microscopic Magnetic Fossils
Scientists have found a new way to measure oxygen levels in the deep ocean using microscopic magnetic fossils preserved in seafloor sediments. The technique, described by Eos, could help researchers reconstruct how ocean oxygenation has changed over time, a key question as warming waters are linked to expanding low-oxygen zones that threaten marine life.
Why now: Interest in new methods for tracking ocean deoxygenation driven by climate change
