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...
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...
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...
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, ...
The following is part 17 in a series on the National Science Foundation's (NSF) Environmental Research and Education (ERE) programs.Parts one, two, threefour, five, six...
The mortality of larval Pacific oysters in Northwest hatcheries has been linked to ocean acidification. Yet the rate of increase in carbon dioxide in the atmosphere and the decrease of pH in near-shor...
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a clustered matrix of th...
Dissolved inorganic carbon, dissolved oxygen, H+, and alkalinity fluxes from permeable carbonate sediments at Heron Island (Great Barrier Reef) were measured over one diel cycle using benthic chambers...
Marine scientists working on the coral reefs of Palau have made two unexpected discoveries that could provide insight into corals' resistance and resilience to ocean acidification.
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2have been reported in the widespread coccolithophor...
Seawater CO2system dynamics were assessed from eastern Pacific reef sites in Panama over 5 consecutive years(2003–2008) and twice in the Gala ′ pagos Islands (2003 and 2009). The seawater CO2system ...
Owing to anthropogenic-induced acidification, surface waters of the high latitudes are projected to become persistently undersaturated with respect to aragonite as early as mid-century. Seasonal arago...
Stony corals build hard skeletons of calcium carbonate (CaCO3) by combining calcium with carbonate ions derived, ultimately, from seawater. The concentration of carbonate ions relative to other carbon...
Coral reefs were one of the first ecosystems to be recognized as vulnerable to ocean acidification. To date, most scientific investigations into the effects of ocean acidification on coral reefs have ...
