Oceanography | Marine Science and Ocean Stories

Satellites can reveal what is happening at sea. SkyTruth founder John Amos explains how seeing previously hidden oil slicks from space changed the course of his career, and why he believes environmental data should be free and public. The conversation follows satellite imagery, AIS vessel tracking, and machine learning into tools such as Global Fishing Watch and Cerulean, which make fishing activity and ocean pollution easier to study and respond to. It also examines the limits of satellite ocean monitoring: observation does not automatically prove illegal fishing, coverage remains uneven, and much of the high seas still goes unseen. This is ocean conservation built to move from evidence to policy and action.

Naming ocean life is the first step toward protecting it. In a live conversation with his former professor, host Clark Marchese asks marine biologist Dr. Manuel Caballero Gutiérrez how many species live in the sea and why the answer remains uncertain. The episode follows marine taxonomy through deep-sea expeditions, DNA analysis, museum collections, and formal species descriptions, connecting species discovery with marine biodiversity, extinction risk, and conservation.

What happens at the deepest points of the ocean? This week on Oceanography, we’re sharing a special feed drop episode from Deep Sea Pod, hosted by Thomas Linley and Alan Jamieson — two scientists many of you may already recognize from previous Oceanography episodes like What Is the Deep Sea Even Like? and Ocean Trenches Explained.

In this episode, Professor Alan Jamieson takes listeners on a deep dive into the hadal zone: the deepest and most extreme region of the ocean, including the massive trenches that extend nearly 11 kilometers beneath the surface. The conversation explores how scientists study these remote environments, what kinds of organisms survive under immense pressure, the history of deep trench exploration, and why the hadal zone remains one of the last great frontiers in marine science.

Where does climate change stand as 2026 unfolds? This Green Frequency crossover steps back from the ocean to assess the wider climate system. Climate scientist Dr. Claudio Piani and student activist Averie Gannon examine global emissions, the Paris Agreement, renewable energy progress, and why every fraction of a degree still matters. It is a grounded climate change 2026 briefing on what is improving, where the gaps remain, and why climate action is still consequential.

Elephant seals collect data where ships rarely can. In this South Pole crossover, Dr. Clive McMahon explains how animal-borne sensors turn deep-diving southern elephant seals into partners in Southern Ocean monitoring. The tags collect temperature, salinity, depth, and ocean productivity data, especially during the Antarctic winter. The episode also explores seal behavior, population decline, Antarctic Bottom Water, climate monitoring, and how hard-to-reach observations improve oceanography and weather forecasting
