Biological effects of OCA

Oceanic uptake of anthropogenic carbon dioxide (CO2) is altering the seawater chemistry of the world’s oceans with consequences for marine biota. Elevated partial pressure of CO2 (pCO2) is [...]

In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, [...]

Rising atmospheric carbon dioxide (CO2), primarily from human fossil fuel combustion, reduces ocean pH and causes wholesale shifts in seawater carbonate chemistry. The process [...]

Understanding how copepods may respond to ocean acidification (OA) is critical for risk assessments of ocean ecology and biogeochemistry. The perception that copepods are insensitive to [...]

Ocean and coastal acidification is occurring due to uptake of atmopsheric CO2, as well as nutrient-fueled respiration in some estuarine and costal environments. Multiple stressors, [...]

Ocean acidification is a pervasive stressor that could affect many marine organisms and cause profound ecological shifts. A variety of biological responses to ocean acidification have been [...]

Although seagrasses and marine macroalgae (macro-autotrophs) play critical ecological roles in reef, lagoon, coastal and open-water ecosystems, their response to ocean acidification (OA) and [...]

Ocean acidification resulting from the global increase in atmospheric CO2 concentration is emerging as a threat to marine species, including crustaceans. Fisheries involving the American [...]

Anthropogenic carbon dioxide (CO2) is being absorbed into the ocean, altering seawater chemistry, with potentially negative impacts on a wide range of marine organisms. The early life stages of [...]

A mesocosm experiment was conducted to quantify the effects of medium term (5 wk) exposure to acidified seawater on the structure of Nereis virens (Polychaeta) burrows and sediment [...]
