Near the intense volcanic CO 2 vents bubbling from the cracks in the seafloor, the water is so acidic that it dissolves coral skeletons. Read more about how reef scientist Laetitia Plaisance uses...
Boring sponges get a bad rap. Their own name betrays them, announcing to the world that they are unexciting, ordinary and quite frankly, boring. However, if ever a misnomer existed, this is it. More...
For three weeks, the research ship MV Chertan is home-base for the scientific team and will be transformed in a floating laboratory to study volcanic CO 2 seeps. Read more about how reef scientist...
Closest to the seeps, where the pH is lowest and the water is most acidic, corals no longer grow. Instead there are sand, rubble and seagrasses that are able to survive. Read more about how reef...
Close to the volcanic CO 2 seeps, the vast diversity of corals that exists in less-acidic waters is replaced by a "monoculture" of boulder corals. These are less fragile and better suited to life in...
Coral reefs are beautiful, vibrant ecosystems that house roughly one quarter of all marine species and provide billions of dollars in products and services to humans each year. But they are also...
Much of the carbon dioxide we emit into the atmosphere ends up in the ocean. As CO 2 levels rise, seawater becomes more acidic. This change in chemistry poses a serious threat to marine organisms...
Far away from the volcanic CO 2 seeps, a healthy coral reef flourishes with a diversity of coral species. Closer to the seeps where the water is acidic, the corals barely even grow. Read more about...
How do we know ocean carbon dioxide levels are rising and pH is decreasing? By taking measurements of seawater over many years. This graph shows rising levels of carbon dioxide (CO 2 ) in the...
Coral reefs are bustling cities of marine life, until rising ocean temperatures turn them into ghost towns. Can reefs spring back from devastating bleaching events? In this episode of the Podcast of...
Researchers can study ocean acidification in the lab by rearing organisms in seawater with variable pH and measuring if they grow, eat, breathe, reproduce, or develop differently. It's common, for...
Scientists don’t often get the opportunity to travel through time. But nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that provides a glimpse today of what could be the...
On World Oceans Day - June 8th, 2012 - the Living Oceans Foundation hosted a live web-based conversation between Sylvia Earle at the Smithsonian's National Museum of Natural History and a team of...
Corals are not only found in shallow tropical waters, but in cold, dark, deep areas of the sea. Amazing coral forests are found at depths of 60-3,050 meters (200-10,00 feet). They support an...
In Ili Ili Bua Bua, Normanby Island, Papua New Guinea, CO 2 bubbles out of intense volcanic vents in the reef. The excess carbon dioxide dissolves into the surrounding seawater, making water more...
Nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that could provide the key to our understanding of one of the biggest threats to coral reef survival: Ocean Acidification...
The acidic waters from CO 2 seeps can dissolve shells and also make it harder for shells to grow in the first place. Read more about how reef scientist Laetitia Plaisance uses carbon dioxide seeps to...
Branching corals, because of their more fragile structure, struggle to survive in acidified waters that surround the volcanic CO 2 seeps of Papua New Guinea. Read more about how reef scientist...
