A new report also cited Venice and the Great Barrier Reef as sites that might be placed on the World Heritage in Danger list

Head scientist at the Smithsonian Marine Station, Valerie Paul, collects blue-green algae samples to study the chemicals they emit. Those chemicals can endanger coral reefs, but also have biomedical potential.

The Pandemic Showed What Can Be Done Without Parachute Science

With international scientists barred from traveling, local scientists in the Pacific islands are taking the chance to lead.

Coral reef health is an important indicator of the ocean’s well-being. Scientists can study corals to learn more about how climate change is affecting the oceans.

DNA Makes Waves in the Fight to Save Coral Reefs

This emerging technique could help scientists understand and anticipate the threats coral reefs face

It’s hard to smell them underwater, but corals, like all living things, release a range of volatile chemicals.

Why Are Scientists Studying Coral's Smell?

Gassy chemicals may tell tales of coral health and climate change

The ring-shaped coral islands known as atolls, like this one in the Maldives Islands in the Indian Ocean, may trace their formation to sea levels repeatedly rising and falling over hundreds of thousands of years, geologists say.

Why Some Geologists Say Charles Darwin's Theory of Coral Atoll Formation Is Wrong

Sea levels rising and falling over hundreds of thousands of years may have helped build the oceanic structures

The health of corals on the Great Barrier Reef is routinely being threatened by hot water temperatures. The Australian government is investigating a range of techniques to try to protect the corals and stave off warming.

Could Flushing Cold Water Over the Great Barrier Reef Save Corals?

Lack of action on climate change is forcing scientists to devise ever more elaborate ways to stave off damage

Pope’s pit viper, a venomous species that lives across Southeast Asia. Someone who is allergic to one type of snake is likely allergic to many types because their venoms have a similar composition.

What Happens When Scientists Become Allergic to Their Research

Researchers spend long periods of time around the organisms they study, and sometimes that exposure has unintended effects

Sea whip coral can come in a variety of colors, from vivid reds and oranges, yellows to rich violets and can grow up to three feet long.

Tangled 'Cord' Mistaken for Litter Is Actually a Sea Creature

Along the East Coast and Gulf of Mexico, beachgoers mistake sea whip coral for discarded junk

The black sea cucumber Holothuria atra is found in shallow waters along reefs and uses sand to coat itself for camouflage and protection from the sun.

Sea Cucumber Poop Could Revitalize Coral Reefs

In one reef, three million sea cucumbers released 64,000 metric tons of nutrient-packed poo back into the ecosystem

Projects that harness the public to make observations and report data about the health of our environment are growing. Anyone can join—no PhDs needed.

Twenty-Four Ways to Turn Outdoor Passions Into Citizen Science

Heading into the new year, consider collecting scientific data while skiing, hiking, surfing, biking and partaking in other adventures

A small hike in the water temperature triggers corals to dispel the algae, causing them to bleach and turn a ghostly shade of white.

Some Corals Can Survive Through Relentless Heat Waves, Surprising Scientists

The organisms can recover during a heat wave instead of afterwards, and scientists call it a 'game changer' for conservation of the species

The study suggests that the island is built from sediment generated by the surrounding coral reef, such as from crushed up dead coral, weathered shells and dried-up microorganisms.

This Pacific Island Is Both Sinking and Growing

Sediment produced by surrounding coral reefs has helped Jeh Island outrace rising sea levels

Damselfish typically live in the nooks and crannies of coral reefs. But do you have anything with more of an open concept?

If a Fish Could Build Its Own Home, What Would It Look Like?

By exposing fish to experimental constructions, scientists hope to find out if replicating coral reefs is really the way to go

A team of scientists on board a research vessel were on a year-long expedition to map the seafloor surrounding Australia when they discovered the reef about 80 miles off the coast of Cape York, Queensland.
