The team settles in for a month on the Great Barrier Reef, the largest reef in the world. One scientist is studying sharks, while another group explores the northern portion of the reef. The team discovers bleaching and severe die-off among corals at the reef. Part of the "Global Reef Expedition" series.

Home to 25% of all marine species, coral reefs protect the coastlines of more than 100 countries and provide 500 million people with jobs. However, reefs are experiencing damage due to climate change, ocean acidification, and other pressures. Mote Tropical Research Lab and the Coral Restoration Foundation, both in the Florida Keys, are performing groundbreaking work by accelerating coral growth in the lab, creating nurseries in the ocean, and replanting on damaged reefs. Their efforts create hope for the future of sustainable coral reefs around the globe.
Describes how coral reefs form and their importance to the sea life they sustain. Gives characteristics of hard and soft coral and shows examples, pointing out that both grow extremely slowly. Locates major coral reefs on a map and restates reefs' contributions to humans. Names several different threats that could destroy these wonderful phenomena.
Oyster reefs protect shorelines from erosion, create fish habitats, and clean the water. Scientists in North Carolina are working to restore the oyster reefs along the coast.
The scientific team visits the Chagos Archipelago, a tropical paradise with some of the healthiest coral reefs on the planet. They want to study reefs seemingly untouched by man but instead become witnesses to a bleaching incident that transforms the reefs right before their eyes. Part of the "Global Reef Expedition" series.
This episode explores one of the largest barrier reefs in the world, which stretches for nearly a thousand miles in the Caribbean Sea. Working together with local scientists and conservation workers, the research team documents the reefs in the Bahamas and probes their ability to cope with the perils of climate change. Part of the "Global Reef Expedition" series.
The reefs around Jamaica, once the most famous in the world, are now struggling just to survive. Local fishermen have to work much harder to make a living. They team up with conservationists, the Jamaican government, and scientists to establish a fishing sanctuary, hoping to restore their endangered fishery. Part of the "Global Reef Expedition" series.
Situated at the meeting of major currents, the Galapagos Islands are not tropical, but in fact they are cold. Reefs around the islands were only discovered in 1975. With the help of a local guide, the team battles rough seas and cold water to explore the reefs. They discover some flourishing reefs at Darwin Island. Part of the "Global Reef Expedition" series.
The Great Barrier Reef is the largest reef on the planet and exists in nutrient poor waters. How does the reef support all the diverse organisms that live on the reef? This episode discusses the relationship between coral and algae, which is the key to the survival of the entire ecosystem. Part of the "Nature's Microworlds" series.
Predatory snails overrun north Florida’s oyster reefs. Dr. David Kimbro investigates what appears to be a localized problem in St. Augustine, Florida. The reefs were being decimated by crown conchs. However, he learns that the same problem is occurring in Apalachicola, Florida. Part of the series "In The Grass, On The Reef."
The American South is home to some of the world’s most spectacular ecosystems, from coral reefs to salt water marshes. These two national monuments are underwater paradises and support a diverse and complex system of plant and animal life.
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.
Staghorn and elkhorn coral have become threatened species. These corals are the building blocks of reefs in the Caribbean and Florida Keys. Part of the "Coral Comeback" series.
The people of the Cook Islands have created one of the world’s largest marine parks, and now they are working together to figure out what that means to a bevy of conflicting interests, from fishermen to miners. The scientists lend their expertise and help the residents map their resources. Part of the "Global Reef Expedition" series.
Australia is home to great biodiversity from the rainforests on land to the Great Barrier Reef in the sea. It is the world's largest coral system and is located off the coast of Queensland, Australia. Part of the "Around the World" series.
The intertidal oyster reefs along Florida’s Gulf Coast are highly productive ecosystems, but they are threatened by rapid decline. Dr. Kimbro is studying this economically important habitat in order to find a way to restore it. Part of the series "In The Grass, On The Reef."
Dr. Randall Hughes is examining diversity within the marsh. She discusses the diversity of the foundation species of a marsh: smooth cordgrass (Spartina alterniflora). Does having a greater diversity of genetically distinct plants make for a healthier marsh? Part of the series "In The Grass, On The Reef."
The intertidal ecosystems lining Florida’s Gulf coast are economically important, but in decline. Dr. Randall Hughes and Dr. David Kimbro, two Florida State University marine ecologists, hope that by studying them, they might gain knowledge that will help preserve salt marshes, oyster reefs, and seagrass beds. Part of the series "In The Grass, On The Reef."
Dr. Kimbro and Dr. Hughes devise an experiment to measure how well juvenile oysters (spat) fare at various test sites. They hope to better understand how predators and environmental factors affect the spat’s chances of survival. Part of the series "In The Grass, On The Reef."
Dr. Randall Hughes is interested in what makes a salt marsh less susceptible to disturbances, such as drought. She looks at species diversity to determine what combinations of plants and animals make for a more productive ecosystem. Part of the series "In The Grass, On The Reef."
