As deep-sea waters warm, scientists expected trouble for the microbes that help keep ocean chemistry in balance. Instead, researchers found that Nitrosopumilus maritimus can adapt to warmer, iron-limited conditions by using iron more efficiently. Because these microbes control key nitrogen reactions that support marine life, their adaptability could help sustain ocean productivity. In a warming world, they may play an even bigger role in shaping marine nutrient cycles.
A new study reveals restoring mangroves could save $800 million in storm damage, protect 140,000 people from flooding, and remove almost triple the amount of CO2 produced by cars in the U.S. every year.
Shifts in the Gulf Stream could help researchers predict the human-driven failure of a huge system of ocean currents known as the Atlantic Meridional Overturning Circulation.
States are preparing for, while trying to avoid, cutbacks to the water they get from the Colorado River. Here are some key things to know about this moment.
Antarctica’s Hektoria Glacier stunned scientists by retreating eight kilometers in just two months, with nearly half of it collapsing in record time. The rapid breakup was driven by a flat, underwater bedrock surface that allowed the glacier to suddenly float and fracture from below. Satellite and seismic data captured the dramatic chain reaction in near real time. The findings raise concerns that much larger glaciers could one day collapse just as quickly.
Detached orca fins scored with distinctive tooth marks suggest that killer whale cannibalism is happening — and it might explain some complex orca societies.
Carbon that has been buried in the Congo Basin's peatlands for millennia is seeping into lakes and rivers. Why this is happening remains unclear, but researchers warn that tropical peatlands could be nearing a tipping point.
Technical diver Stratis Kas is the editor-in-chief of InDEPTH and the lead author of “Close Calls.” Inspired by the need for more open conversations about near-misses, “Close Calls” shares hard-earned lessons from prominent dive industry figures, and reminds readers that even the most advanced divers make and learn from mistakes.
In this episode with Frauke Tillmans, VP of research at DAN, Stratis also discusses his experiences as an exploration diver and a storyteller in the diving community — as well as his plans to carry forward InDEPTH’s mission to expand knowledge of what’s possible underwater and to spark dialogue across the diving world.

A lost cache of 250-million-year-old fossils from Australia has rewritten part of the story of life after Earth’s worst mass extinction. Instead of a single marine amphibian species, researchers uncovered evidence of a surprisingly diverse community of early ocean predators. One of these creatures had relatives stretching from the Arctic to Madagascar, showing that some of the first sea-going tetrapods spread across the globe with remarkable speed.
