Drilling for minerals deep in the ocean could have immense consequences for the tiny animals at the core of the vast marine food web — and ultimately affect fisheries and the food we find on our ...

Disappearing sea ice is letting more sunlight in the Arctic Ocean and boosting phytoplankton growth, but this has depleted a ...

Predators at the top of a marine food chain 130 million years ago ruled with more power than any modern species, McGill research into a marine ecosystem from the Cretaceous period revealed. Trophic ...

Smoke and ash could poison plankton and other organisms that form the foundation of the marine food chain, biologists say. Heavy smoke, ash and debris from Southern California’s raging wildfires ...

The ocean floor hosts a remarkable diversity of plant life, vital for both marine ecosystems and the planet’s health. Unlike land plants, underwater flora must adapt to low light, high pressure, and ...

Long before whales and sharks, enormous marine reptiles dominated the oceans with unmatched power. Scientists have reconstructed a 130-million-year-old marine ecosystem from Colombia and found ...

Melting Arctic ice is revealing a hidden world of nitrogen-fixing bacteria beneath the surface. These microbes, not the usual cyanobacteria, enrich the ocean with nitrogen, fueling algae growth that ...
