Sentinels ocean acidification survived Earth last mass extinction
2020/10/10
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 Ocean Acidification Weakens Coral Skeletons
2018/2/1
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...
Ocean acidification may cause dramatic changes to phytoplankton

2015/8/4
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, three, four, five, six...
Ocean acidification a culprit in commercial shellfish hatcheries' failures
Ocean acidification culprit in commercial shellfish hatcheries' failures
2014/12/30
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...
Comparative responses of two dominant Antarctic phytoplankton taxa to interactions between ocean acidification, warming, irradiance, and iron availability
two dominant Antarctic phytoplankton taxa ocean acidification warming irradiance iron availability
2014/10/16
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...
Carbon cycling hysteresis in permeable carbonate sands over a diel cycle: Implications for ocean acidification
Carbon cycling hysteresis permeable carbonate sands over a diel cycle ocean acidification
2014/4/2
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...
Palau's coral reefs surprisingly resistant to ocean acidification

2014/3/17
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.
Ocean acidification exacerbates the effect of UV radiation on the calcifying phytoplankterEmiliania huxleyi
Ocean acidification UV radiation the calcifying phytoplankter Emiliania huxleyi
2014/4/17
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2have been reported in the widespread coccolithophor...
Ocean acidification hot spots: Spatiotemporal dynamics of the seawater CO2 system of eastern Pacific coral reefs
Ocean acidification hot spots Spatiotemporal dynamics the seawater CO2 system eastern Pacific coral reefs
2014/4/16
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 ...
Ocean Acidification at High Latitudes: The Bellwether
Acidification surface water aragonite underground water sea sea creatures the cold water coral sea urchins mollusks
2015/7/6
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...
Why Corals Care About Ocean Acidification: Uncovering the Mechanism
Stone coral skeletons calcium carbonate carbonate ions the sea the coral
2015/7/6
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...
