SEATTLE (AP) — For decades, scientists believed Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic ...

Myctophids, also known as lanternfish, are considered a key connection between the deep ocean food web and marine life closer to the surface. (Austin Straub / For the Times) For several years now, one ...

Drilling for minerals deep in the ocean could have immense consequences for the tiny animals at the core of the vast marine ...

Tiny ocean microbes called Prochlorococcus, once thought to be climate survivors, may struggle as seas warm. These cyanobacteria drive 5% of Earth’s photosynthesis and underpin much of the marine food ...

New research shows that marine heat waves can reshape ocean food webs, which in turn can slow the transport of carbon to the deep sea and hamper the ocean's ability to buffer against climate change.

Phytoplankton—microscopic algae that form the base of ocean food webs—have long been viewed as transient players in the global carbon cycle: They bloom, die, and the carbon they contain is quickly ...
