How To Protect The Ocean

Right now, somewhere in the open ocean, a raft the size of a small table is drifting with no one steering it. It's called a fish aggregating device, or FAD, and the tuna industry drops thousands of them into the water every year to lure fish to the surface. A new study published in Science Advances tracked where these rafts actually end up, and the answer is unsettling: they've likely drifted through more than half of the world's marine protected areas by total area, with over 6,300 strandings r

Scientists have uncovered an incredible secret hiding in plain sight on coral reefs. Some tropical sea sponges are able to harvest sunlight through microscopic algae living inside their tissues, giving them a surprising source of energy. It is a discovery that challenges what we thought we knew about one of the ocean’s oldest animals.In this episode, we explore how these ancient filter feeders use a partnership with algae to survive and thrive in nutrient-poor tropical waters. You’ll learn why

Sea level rise isn’t always dramatic. Long before homes disappear beneath the waves, coastal communities can lose something even more essential: safe drinking water. In this episode, we explore how saltwater is quietly moving into freshwater supplies across coastal Bangladesh and why this hidden impact deserves far more attention.Using a recent Mongabay commentary as a starting point, you’ll learn how rising seas, changing rivers, and human activities are combining to reshape one of the world’

The world just pledged more than $6.4 billion for ocean conservation at the 2026 Our Ocean Conference, but history tells us that big announcements do not always lead to meaningful action. In this episode, we unpack what was actually announced, who made the commitments, and why the headline number is only part of the story. You’ll learn why this year’s conference in Kenya was especially significant and what makes these commitments different from legally binding agreements.We also explore the qu

Thousands of seabirds are washing ashore along California’s coast, starving, exhausted, and unable to find enough food. While the images are heartbreaking, scientists say the birds are only the visible symptom of a much larger problem unfolding beneath the surface. In this episode, we explore why seabirds are dying and what their struggle reveals about the health of the Pacific Ocean.You’ll learn how marine heat waves are disrupting one of the world’s most productive ocean ecosystems by reduci

Canada has admitted it is no longer on track to meet its 2030 climate targets, but the reasons go far beyond domestic politics. In this episode, we explore how changing economic priorities are reshaping Canada’s approach to climate action. The surprising twist is that many of these changes begin outside Canada’s borders.New U.S. tariffs and shifting trade policies are putting pressure on Canada’s economy, forcing leaders to rethink where to invest and what to prioritize. As economic policy cha

Most of us will never visit the deep ocean, yet it covers the majority of our planet and supports life in ways we’re only beginning to understand. In this episode, Andrew Lewin wraps up the Surfacing Secrets series with Ocean Networks Canada by exploring why the deep sea remains one of Earth’s greatest frontiers. You’ll discover how scientists are uncovering hidden ecosystems that could reshape our understanding of the ocean.Andrew is joined by Monica Peltz of Ocean Networks Canada and Heidi G

How do you protect something you barely understand? In this episode, we explore why ocean exploration is much more than discovering strange creatures or mapping the seafloor. Every marine protected area, conservation plan, and fisheries decision begins with one essential ingredient: knowledge.You’ll discover how scientists collect the information that guides conservation, from mapping underwater canyons to identifying coral gardens and sponge reefs that most people will never see. We also look

The deep ocean is one of the most extreme places on Earth. Crushing pressure, freezing temperatures, and total darkness make it impossible for humans to explore for long, yet scientists continue to make incredible discoveries thousands of meters below the surface. So how do they do it?In this episode, you’ll discover the remarkable technology that makes deep sea exploration possible. From remotely operated vehicles and autonomous underwater robots to multibeam sonar, artificial intelligence, a

Most people picture the deep sea as a dark, empty place where almost nothing can survive. The truth is far more surprising. Thousands of meters below the surface lives an extraordinary world filled with ancient corals, giant sponges, glowing jellyfish, strange fish, and species that scientists are still discovering today.In this episode, you’ll learn how life has adapted to crushing pressure, freezing temperatures, and complete darkness. You’ll also discover why deep-sea ecosystems are some of
