Every weekday morning, 23,000 marine scientists, oceanographers, and ocean-obsessed readers open DRIFT — the free briefing on ocean science, marine biology, and the forces that govern 71% of our planet.

New autonomous surface measurements from the ARGO float network show microplastic concentrations in the North Atlantic sunlight zone tripling over a 12-year period. The numbers challenge every existing cleanup timeline and raise a question the scientific community has been reluctant to ask aloud: is surface collection physically possible at the required scale?
Every night, trillions of organisms migrate from the deep ocean to the surface to feed, then descend before dawn. This migration transports more carbon downward than any other biological process on Earth. A new analysis shows it is also significantly affected by light pollution from ships — with consequences nobody has fully modelled yet.
The polymetallic nodule fields targeted for deep-sea mining are among the least surveyed ecosystems on Earth. A consortium of deep-sea biologists has compiled the first species inventory for the Clarion-Clipperton Zone — and found that fewer than 10% of the species identified have been formally described. Everything else is new to science.
The Antarctic Bottom Water current — a dense, cold, oxygen-rich flow that spreads across the abyssal seafloor — has been observed for decades. New measurements using acoustic Doppler current profilers show it is both faster and more variable than believed, with direct implications for global heat and carbon transport models.
DRIFT covers ocean science as a rigorous empirical discipline with direct consequences for the atmosphere, the food system, and the global economy. We treat the evidence seriously and the uncertainty honestly.
One finding from oceanography, marine biology, or ocean chemistry — reported from peer-reviewed literature with full methodological context.
How scientists actually measure the ocean — Argo floats, acoustic tomography, sediment cores, autonomous vehicles — explained precisely.
What we still don't know — and why the gaps in our ocean knowledge are as significant as the findings we've confirmed.
How this week's ocean science connects to climate, food, economy, and governance — the ocean is everything's downstream.
