Story summary

A groundbreaking study by Subhendu Chakraborty at the Leibniz Centre for Tropical Marine Research uncovers that marine snow nourishes heterotrophic bacteria, crucial for nitrogen fixation in the ocean's depths. These bacteria, thriving in oxygen-poor zones and peaking at 63°F, play a vital role in stabilizing marine ecosystems by contributing 10% of total nitrogen fixation.
