Building an oxygen-rich world doesn’t require volcanism, supercontinent breakups or the rise of land plants — just nutrient cycling, a study finds.
Ocean slicks serve as calm, food-rich nurseries for larval fish. A new study shows that slicks also accumulate plastics, which get eaten by baby fish.
A study reveals new details of how humpback whales hunt using their flippers and a whirl of bubbles to capture fish.
Meet 10 young researchers who combine persistence and passion to make headway on science’s big questions.
A new IPCC report gives the lowdown on how climate change is already wreaking havoc on Earth’s oceans and frozen regions, and how much worse things could get.
Several widespread corals in the Red Sea are flubbing cues to spawn en masse.
The Pliocene era cave formations on the Spanish coast of Mallorca offer hints about how oceans could respond to human-driven climate change.
Kilauea’s heavy flow of lava into the ocean in 2018 added both food and heat to fuel a sudden bloom of ocean algae.
Ocean acidification may lead to smaller, lighter diatoms in seawater, which could also shrink how much carbon the tiny ocean algae can help sequester.
A parasitic bacterium that preys on corals quickly reproduces when it senses more nutrients in its host.
