Ocean Acidification Press Releases

Carbonate chemistry and carbon sequestration driven by inorganic carbon outwelling from mangroves and saltmarshes

Mangroves and saltmarshes are biogeochemical hotspots storing carbon in sediments and in the ocean following lateral carbon export (outwelling). Coastal seawater pH is modified by both uptake of anthropogenic carbon dioxide and natural biogeochemical …

Climate change threatens a quarter of Australia’s low-lying coral reef islands

Coral islands support and extend legal maritime jurisdictions. University of Sydney researchers have found 25 percent of Australia’s coral islands, land masses formed by reefs, currently face high to very high risk of being wiped out by climate change. The …

Dynamics of pH at Santa Catalina Island

The local expression of ocean acidification may depend on local oceanographic features in addition to global forcings. Our objective is to provide a baseline of pH behavior at Santa Catalina Island, situated within the unique oceanographic characteristics …

Spatiotemporal reconstruction of global ocean surface pCO2 based on optimized random forest

Highlights Abstract The partial pressure of ocean surface CO2 (pCO2) plays an important role in quantifying the carbon budget and assessing ocean acidification. For such a vast and complex ocean system as the global ocean, most current research practices …

Shallow-water carbonate facies herald the onset of the Palaeocene eocene thermal maximum (Hazara basin, Northern Pakistan)

Highlights Abstract We investigate the Palaeocene succession of the Hazara Basin (Northern Pakistan) to better understand the impact of climate change on marine carbonate-producing organisms. These shallow-water carbonates, deposited during the Late …

Late Cenomanian Plenus event in the Western Interior seaway

The Late Cenomanian Plenus Cold Event is one of the most enigmatic paleoclimate episodes in Earth history with potential to inform understanding of global climate system variability under greenhouse warming conditions, as well as internal feedback pathways …

Resilience against the impacts of climate change in an ecologically and economically significant native oyster

Highlights Abstract Climate change is acidifying and warming our oceans, at an unprecedented rate posing a challenge for marine invertebrates vital across the globe for ecological services and food security. Here we show it is possible for resilience to …

Adaptive responses of eelgrass (Zostera marina L.) to ocean warming and acidification

Highlights Abstract Ocean warming (OW) and ocean acidification (OA), driven by rapid global warming accelerating at unprecedented rates, are profoundly impacting the stability of seagrass ecosystems. Yet, our current understanding of the effects of OW and …

Risk classification of low-lying coral reef islands and their exposure to climate threats

Highlights Abstract The bio-physical responses of low-lying coral islands to climate change are of concern. These islands exist across a broad range of bio-physical conditions, and vulnerabilities to rising and warming seas, ocean acidification and …

Future warming stimulates growth and photosynthesis in an Arctic microalga more strongly than changes in light intensity or pCO2

We assessed the responses of solitary cells of Arctic Phaeocystis pouchetii grown under a matrix of temperature (2°C vs. 6°C), light intensity (55 vs. 160 μmol photons m−2 s−1) and pCO2 (400 vs. 1000 μatm CO2, i.e., 40.5 vs. 101.3 Pa). Next to acclimation …

Systems thinking approach to understand Indonesia’s ocean acidification

Establishing a proper connection between content and context is essential to infusing Systems Thinking (ST) into sustainable chemistry learning. Several efforts have been made to realize ST in chemistry in the context of coping with climate change through …

Atlantic Ocean near Bermuda is warmer and more acidic than ever, 40 years of observation show

Decade-long ocean warming that impacts ocean circulation, a decrease in oxygen levels that contributes to changes in salinification and nutrient supply, and ocean acidification are just some of the challenges the world’s oceans are facing. In 1988, a …
