Keeping Watch Over Seabirds at the World’s Edge | Hakai Magazine In Alaska, one of the longest-running and most comprehensive seabird monitoring projects is equal parts tedium, adventure, truth, and beauty.

With Trump pushing offshore oil drilling, including around St. Matthew Island (alaskapublic.org/news/politic...), it's a great time to re-up my story about oil and the origins of western marine science in Alaska, and how long-term monitoring helped reveal a different kind of oil "spill" there:

Hunting the Most Elusive Whale Historically, beaked whales have been near impossible to study. But modern acoustic and genetic technologies are giving scientists new hope.

Beaked whales are the most elusive large animals on the planet. They live offshore, dive deep, and are nearly impossible to distinguish from each other visually. But with acoustics and genetics, scientists finally have inroads on how to study these mysterious whales. 🐬🔍

We’re doing this work because we believe that informed and inspired people will build a better relationship with the natural world. And we intentionally produce bioGraphic for regular people—not just politicians or professors—because it’s regular people, everywhere, who push our societies to change.

Triaging the Global Wildlife Trade - bioGraphic Can we take a more systematic approach to protecting endangered species from international trade?

The Convention on International Trade in Endangered Species is the world's largest agreement overseeing wildlife trafficking. Yet hundreds of species slip through the cracks. What gets protected? And is there a systematic solution?

Poop-Cam Footage Shows These Seabirds Fertilize the Ocean With Their Body Weight Per Day in Guano Recording Streaked Shearwaters gave scientists a new window into the role seabirds play in fueling marine food webs—and possibly spreading avian flu—far from land.

Bird poop is rich with nutrients and has a huge impact on the environment, yet scientists know next to nothing about scat at sea. Rearview poopcams strapped to shearwaters reveal a lot about these fowl movements.
