Kelp forests are declining in many regions due to ocean warming, predator loss, and other anthropogenic stressors. In areas of rapid ocean warming, including the southern Gulf of Maine, these ecosyst...

Pollution, warm oceans and hungry urchins devastated Pacific kelp. Now, thanks to divers with hammers, one of the world’s most successful rehabilitation projects has helped it rebound

We systematically reviewed literature on macroalgal degradation. To date, most degradation experiments are carried out in aquaria or shallow environments, span short timescales or rarely incorporate ....

How do fish communicate in a noisy ocean? A new NOAA-supported study analyzed 18 years of recordings to map the 'who, when, and where' of fish chorusing in three national marine sanctuaries in Califor...

After a decade of carnage, we finally know what’s devastating sea stars along North America’s West Coast. Does that mean scientists can save them?

Coastal regions are complex habitats, where multiple natural and anthropogenic drivers can interact to affect the survival and growth of marine organisms. The giant kelp Macrocystis pyrifera is sensi...

Ocean warming is driving profound changes in the ecology of marine habitat formers such as kelps, with negative implications for the biodiversity and ecosystem services they support. Thermal stress c...

In temperate regions experiencing rapid ocean warming, kelp forests are being replaced by chemically rich turf algae. However, the extent to which these turf algae alter the surrounding chemical envir...

In the coastal waters around Sydney, a team of dedicated scientists is restoring crayweed forests.

Into the Blue: Securing a Sustainable Future for Kelp Forests global synthesis report is the most comprehensive knowledge review on kelp to date, revealing the state of science on the world’s kelp for...
