Ethereal, swaying pillars of kelp along California's coasts grow up through the water, to form a dense surface canopy of thick fronds that provide homes for numerous marine creatures.Scientists have s...
Two groups of tiny, delicate marine organisms -- sea butterflies and sea angels -- were surprisingly resilient in the face of dramatic global climate change and Earth's most recent mass extinction eve...
Scientists have long suspected that ocean acidification is affecting corals' ability to build their skeletons, but it has been challenging to isolate the effect of acidification from the effect of sim...
The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study details how ocean acidification affects coral skeletons, enabling scientists...
A research team, led by University of Delaware professor Wei-Jun Cai, has identified a zone of water that is increasing in acidity in the Chesapeake Bay.The team analyzed little studied factors that p...
Ocean acidification (OA) is spreading rapidly in the western Arctic Ocean in both area and depth, according to new interdisciplinary research reported in Nature Climate Change by a team of internation...
A study of California mussels, a key species in the rocky intertidal ecosystems of the West Coast, indicates that the effects of ocean acidification will vary from place to place along the coast depen...
In a new study, University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers found that the limestone that forms the foundation of coral reefs along the Florida Reef Tract ...
An interdisciplinary team of researchers led by University of Delaware professors Wei-Jun Cai and Mark Warner has successfully measured both pH and carbonate ion concentration directly inside the calc...
Emissions of carbon dioxide are causing the oceans to become more acidic. Recent experiments show that this ocean acidification threatens many ocean ecosystems. The ancient past may provide a cautiona...
Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, ...
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
Ocean Acidification:The Role of CO2.
The objective of this inquiry-based lesson is for students to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms. During this activity, students: (1...
The Moorea Coral Reef Long Term Ecological Research program affords a unique opportunity to study the implications of ocean acidification (OA) for coral reefs, as ongoing ecological and physical monit...
