Travels to over a dozen locations exploring the state of global fisheries. Explores the consequences in the Indian Ocean of nets with mesh so fine that even seawater only trickles out, the potential extinction of tuna in the Mediterranean and the North Atlantic, and the impact of land-based sources of pollution on coastal fishing areas. Part two of this series reports on the search for solutions.

Goes in search of sustainable solutions. In the Canary Islands, fishermen use rod and line for a valuable species and only take fully mature fish. In Oman, the authorities will only allow fishermen to use one kind of boat and net, and they strictly monitor the catches. Leading decision-makers describe how drastic action must be taken to protect wild stocks and ecosystems, but almost nowhere are measures being taken that help alleviate the crisis. Part one of this series explores the state of global fisheries.
Scholar Johan Norberg travels to New Zealand to find out how the Quota Management System has helped save fish populations. Thirty years ago, New Zealand fisheries were on the brink of disaster due to overfishing. Today, commercial fishing off New Zealand provides fish for consumers worldwide, an excellent livelihood for fishers, and a stronger, healthier ocean and fish population.
Different processes in nearby coastal oceans drive the ecosystems found in the Mediterranean climate zones. Atmospheric processes over the oceans influence seasonal rainfall patterns, while currents and ocean temperatures affect both local and regional climate conditions. Part of the "Mediterranean-Climate Ecosystems" series.
During a visit to Thailand, Jeff explores the underwater worlds of the Gulf of Thailand and the Andaman Sea. He also pays a visit to conservationists from Eco Koh Tao who are fighting to restore endangered coral reefs and giant clams. Part of the "Ocean Mysteries" series.
Part of "The Living Oceans" series. Captures the lives of predators and prey in the world's oceans. Explores the hunting habits and defenses in the populations of several species.
The blackspotted puffer fish lives in the Pacific and Indian Oceans. To scare away predators, it puffs its body up like a balloon. However, this fish is poisonous, so it's not safe to eat. Now, that's one weird animal. Part of the "Weird Animal" series.
Maritime archaeology is a discipline within archaeology that specifically studies human interaction with oceans, lakes, and rivers through the study of artifacts. Researchers trace the historical aspects of human dependence and influences on bodies of water. Some areas of interest include harvested goods from the sea, fishing techniques, transportation, and water quality. Part of the "Adventures of a Maritime Archaeologist" series.
Narration, song, and underwater photography capture the primary characteristics of fish: scales, gills, and fins. Shows how fish swim and how they protect themselves. Labels identify key words.
This segment is all about climate and the role of water and wind. Climate is the statistics of weather over long periods of time. Other topics covered include atmosphere, oceans, and weather. Part of the "Earth Science" series.
The marine reptiles Ichthyosaurs arose after the Great Dying, which wiped out at least 90 percent of life in the oceans. This event changed the seas forever and triggered a new evolutionary arms race between predator and prey. Part of the “Eons” series.
Part of "The Living Oceans" series. Captures the ecological balance established between animals and plants on a Caribbean coral reef. Details the symbiotic and commensally symbiotic relationships along with the predator/prey relationship.
Ecosystems and biomes exist around the globe in various regions. Students will explore the plant and animal life found in tropical rainforests, deserts, and oceans. Part of the Real World Science series.
When the thermohaline circulation system stops flowing, Dr. Mother Nature calls in superhero Bruce Rain to help. As he works to solve the problem, he and Dr. Mother Nature explain the importance of oceans in regulating the Earth's temperature. Part of "The Science of Climate" series.
The Great Pacific Garbage Patch is a large area of marine debris, which forms by rotating ocean currents. These currents, also known as gyres, act like whirlpools and collect floating pieces of microplastics. Part of the "Trash Talk" series.
This demonstration uses a water balloon to show how Earth's oceans are absorbing most of the heat in the atmosphere. The trapped heat in the ocean is warming the planet. Part of the “DIY Space Classroom Activities” series.
A lot of the trash that's in the ocean is plastic, and that marine debris is damaging the environment, economy, and the health of animals. The problem will only get worse unless humans change the way they consume and dispose of products. Part of the "Trash Talk" series.
Jupiter's moon Europa may have an ocean more than twice the size of Earth's oceans combined. Why do scientists think so? A spacecraft collected evidence that revealed Europa's surface is mostly made of water. It also showed lots of cracks and ridges, but not many craters, which may indicate a large hidden ocean.
Rising acidity in sea water is harmful to all ocean life. This short animated video explains how burning fossil fuels is increasing the acidity of the world's oceans. This is also impacting the fragile underwater ecosystems.
