MCB: Can Brighter Clouds Cool the Planet? with Dr....

Oceanography ·

2026/04/07

Can brighter clouds cool Earth? Marine cloud brightening (MCB) is a proposed solar radiation modification strategy that could reflect sunlight, cool ocean regions, and potentially reduce dangerous heat. But can it actually work at scale, and what risks might come with it? In this episode, climate scientist Dr. Jessica Wan explains how MCB works, why researchers are studying sea salt aerosols and marine stratocumulus clouds, and what climate models reveal about unintended effects on weather,

mCDR: Can the Ocean Store Our Carbon for Centuries?...

Oceanography ·

2026/03/31

We may need to remove carbon from the atmosphere—can the ocean help? Biomass-based marine carbon dioxide removal (mCDR) explores whether natural ocean processes can help store carbon for the long term. Oceanographer and biogeochemist Dr. Morgan Raven explains how organic carbon moves through marine systems, why low-oxygen environments like deep-sea brines and fjords may enable long-term carbon sequestration, and what scientists still need to understand before these approaches can scale.

Ocean Trenches Explained with Prof. Alan Jamieson

Oceanography ·

2026/03/17

Ocean trenches are Earth’s deepest habitats—and they’re full of life. This episode is a guided dive into the hadal zone (6,000–11,000 meters), where tectonic plates create steep trenches that plunge toward the mantle. Learn what trenches are geologically, what conditions are like at full ocean depth (cold, pressure, darkness), and why the deep sea isn’t a single ecosystem—each trench is its own world. You’ll also get myth-busting on how “the abyss” shows up in pop culture, plus an inside look at the

What is the deep sea — really? Deep-sea researcher Dr. Thom Linley (Curator of Fishes at Te Papa Tongarewa, National Museum of New Zealand) breaks down the deep ocean as a connected world with distinct zones, ecosystems, and rules — not one mysterious “blob.” From the bathyal and abyssal to the hadal trenches, this conversation maps what’s down there, how life survives crushing pressure and perpetual darkness, and why the deep sea functions as the engine under the hood of the entire planet.This

What is Ocean Deoxygenation? with Dr. Sven Pallacks

Oceanography ·

2026/03/03

Ocean oxygen shapes marine life in ways most of us never think about. This episode explores how oxygen enters the ocean (air–sea exchange and photosynthesis), how it circulates through surface waters and the deep sea, and why scientists track changes in oxygen over time. Learn what oxygen minimum zones are, how they form, and what they can mean for midwater ecosystems in the mesopelagic (“twilight”) zone.Featuring research that uses fossil fish ear bones (otoliths) preserved in seafloor sediment,

Making marine biodiversity visible for everyone Marine biodiversity is vast, complex—and mostly out of sight. In this “ocean story hour” episode, a Paris-based science communicator, Anabelle Chaumun, shares how to translate marine research into stories people can actually feel and remember. We explore why misinformation spreads faster than evidence, why ocean issues can feel distant, and how storytelling (and images) can make the invisible ocean world tangible. Anabelle also introduces EMBRC (the

What have we learned about microplastics over the last 20 years? This episode surveys two decades of ocean microplastics science: where microplastics come from (fibers, tires, fragmentation, microbeads), where they’re found (shorelines, water column, sea ice, deep sea), and what research shows about impacts across food webs and ecosystems. It also unpacks major gaps—nanoplastics, fragmentation rates, and the thousands of chemicals used in plastics—plus why scientists argue for a precautionary

Marine heat waves can make summer heat even worse. New climate research shows that unusually warm ocean conditions don’t just damage marine ecosystems — they can also intensify extreme heat on land. In this episode, Mr. Hirotaka Sato, a Japan Meteorological Agency climate scientist explains how marine heat waves form, why the ocean stores most of Earth’s excess heat, and how a 2023 marine heat wave near northern Japan amplified record-breaking temperatures onshore. Learn the mechanisms behind

How oil research protects ocean health. Understanding oil spills, offshore drilling, and marine pollution starts before any accident happens. In this episode, marine microbial oceanographer Dr. Alice Ortmann explains how scientists collect baseline ocean data to measure ecosystem health in oil and gas regions offshore Newfoundland. The conversation covers what counts as an oil spill, how oil and methane move through the water column, why microbes are essential for breaking down hydrocarbons, and how
