Increased CO2 and temperature acted together to increase the growth of algal turfs, which produced twice as much biomass and covered four times as much space. Experimental removal of algal turfs led to greater establishment of young kelp. The findings suggest that ocean acidification and warming could potentially cause a ...
Ocean acidification increased the rate at which sponges bored into scallop shells. At pH 7.8, sponges bored twice the number of papillar holes and removed two times more shell weight than at pH 8.1. Greater erosion caused by the lower pH weakened the scallop shells. A warmer water temperature had ...
This field study in Papua New Guinea examined the effects of natural carbon dioxide seeps on coral reef ecosystems. At reduced pH, coral diversity was lower, population replenishment and abundance of some corals decreased, and interactions among species changed. Reef development ceased below pH 7.7. Ocean acidification, together with warmer ...
In ocean acidification conditions (pH 7.7) embryos of an intertidal barnacle developed more slowly. Survival of adult barnacles dropped by 22 percent, and the mineral structure of adult shells changed. (Laboratory study)
Post-larvae of an intertidal barnacle (Elminius modestus) grew more slowly under ocean acidification conditions, but there were no impacts on its shell calcium content and survival by either ocean acidification or warmer temperature. were observed in high CO2 but there were no impacts on shell calcium content and survival by ...
Ocean acidification (pH 7.7) impaired growth and development of an intertidal barnacle (Semibalanus balanoides), but warmer temperature (+4 °C) did not. The mineral composition of the shells did not change with either ocean acidification or warmer temperature. The combination of reduced growth and maintained mineral content suggests that the barnacles ...
The seasonal variability of inorganic carbon in the surface waters of the Scotian Shelf region of the Canadian northwestern Atlantic Ocean was investigated. Seasonal variability was assessed using hourly measurements, covering a full annual cycle, of the partial pressure of CO2, (pCO2), and hydrographic variables obtained by an autonomous moored ...
The accumulation of carbon dioxide in the atmosphere will lower the pH in ocean waters, a process termed ocean acidification (OA). Despite its potentially detrimental effects on calcifying organisms, experimental studies on the possible impacts on fish remain scarce. While adults will most likely remain relatively unaffected by changes in ...
Underway and in situ observations of surface ocean pCO2, combined with satellite data, were used to develop pCO2 regional algorithms to analyze the seasonal and interannual variability of surface oceanpCO2 and sea-air CO2 flux for five physically and biologically distinct regions of the eastern North American continental shelf: the South Atlantic Bight (SAB), the Mid-Atlantic ...
Ocean acidification represents a threat to marine species worldwide, and forecasting the ecological impacts of acidification is a high priority for science, management, and policy. As research on the topic expands at an exponential rate, a comprehensive understanding of the variability in organisms' responses and corresponding levels of certainty is ...
