For nearly half a century, Brown University marine biologist Jon Witman has been diving Cashes Ledge, an underwater mountain ...

A research trip to a biodiversity hotspot in the Gulf of Maine underscores the importance of continued monitoring of marine ecosystems.

Kelp forests are underwater thickets of algae that keep the world’s oceans rich with biodiversity. And scientists just offered a strong financial argument for keeping them healthy.

Kelp forests provide crucial habitats to support marine animals, and humans around the world benefit from healthy kelp because they protect our coastlines from waves, absorb carbon dioxide from ...

Globally, kelp forests are in trouble. We knew that starting around 2014, 2015, there had been a really serious collapse of Northern California’s bull kelp forests.

This year, we issued the Kelp Forest Challenge to communities around the world: let’s aim to protect 3 million hectares of surviving kelp and restore one million more hectares by 2040.

Aquarium researchers found that in Northern and Southern California, within the last century, the kelp forest has declined drastically by 63 and 52 percent, respectively. Meanwhile, in Central Cali… ...

Kelp forests are economically, ecologically, and culturally important habitats and are essential to restore and protect,” said Deb Self, Greater Farallones Association Executive Director.

Kelp forests are made up of thick, undulating ribbons of brown algae that hang on to rocks at the seafloor and grow toward the light above. Kelp is found in dense groups, like trees on land, hence ...

Over 90 percent of the heat trapped on Earth because of the greenhouse gases emitted by humans has been absorbed by the ocean, increasing its temperature. But kelp prefers cooler waters.

Braving sharks and hordes of urchins, scientists are growing kelp one forest at a time Grant Stringer, The Mercury News Nov 6, 2024 Updated Nov 6, 2024 ...

For example, records over a 50-year period show that within the La Jolla kelp forest, the northern section has much shorter periods of persistence — and reappearance — than the southern section.
