What Makes Seagrass Survive? Look to the Microbes

On her first day of graduate school, Karolina Zabinski rose at 4:00am. She spent the day on the muddy shores of Tomales Bay, collecting eelgrass for a survey of aquatic plant diseases. These ribbon-like seagrasses are common along the California coast and form knee-high meadows that undulate in the water.

Survival of the Most Cooperative

Rarotonga, the largest island in the archipelago of the Cook Islands, is protected by a coral reef that forms a barricade around the kidney-shaped dollop of terra firma moored in the middle of the South Pacific. If that reef were to die off or disappear—as reefs are, globally, at a disheartening rate—it would spell catastrophe for Rarotonga’s more than 10,000 inhabitants. That partly explains how Anya Brown came to be a regular at a hardware store on the island.

Methane and Climate Change

When oceanographer Tessa Hill was asked to join the Climate Crisis Advisory Group (CCAG) as an advisor, she was surprised by the reason. The global group, formed in 2021 with the vision of acting as a bridge between the latest climate science and policymakers, was interested in Hill’s background expertise in methane, a potent greenhouse gas.
