New MBARI project: The Emerging Science of a High CO2 / Low pH Ocean

This project developed by the Monterey Bay Aquarium Research Institute (MBARI) proposes to tackle the problem of assessing the future impacts of elevated oceanic CO2 levels (lower pH) on marine ecosystems through a unique combination of field and laboratory studies, and to address the associated policy, economic, and permitting issues. This work will draw on […]

Climate change will leave a sour taste in our mouths – literally: Study shows ocean acidification affects the flavour of shellfish

It is a popular appetiser at this time of year, but Marie Rose could soon be a lot less paletable, according to a new study. Marine biologists have found that shellfish take on a sour flavour if they are reared in slightly acidified sea water. They warn that as the planet’s oceans grow more acidic, […]

Environment Break: Understanding ocean acidification (video & text)

On Environment Break the focus is on ocean acidification, which is a threat to the coral reefs marine eco-system. Edlyn Ruiz talks to University of Essex’s Emma Camp and Department of Environment’s John Bothwell to find out more about how this has impacted Cayman’s waters. Delisa Hernandez, Cayman 27, 22 december 2014. Video & text.Filed […]

Considerations for the measurement of spectrophotometric pH for ocean acidification and other studies

Indicator-based spectrophotometric pH is commonly used for the analysis of seawater because of its high precision and long-term reproducibility. Users come from an increasingly diverse range of disciplines, primarily motivated by studies focused on the causes and effects of ocean acidification. Show More Summary

Combined metabolome and proteome analysis of the mantle tissue from Pacific oyster Crassostrea gigas exposed to elevated pCO2

Ocean acidification (OA) has been found to affect an array of normal physiological processes in mollusks, especially posing a significant threat to the fabrication process of mollusk shell. In the current study, the impact of exposure to elevated pCO2 condition was investigated in mantle tissue of Crassostrea gigas by an integrated metabolomic and proteomic approach. […]

Metabolic rate and activity of blue mussel Mytilus edulis trossulus under short-term exposure to carbon dioxide-induced water acidification and oxygen deficiency

This work investigated the effect of carbon dioxide-induced decreased water pH (8.1 – control, 7.5 and 7.0), oxygen saturation (~100% and ~20%) and the combination of both factors on the behaviour (gaping activity) and the total metabolic rate of blue mussel Mytilus edulis trossulus from the southern Baltic Sea. Heat dissipation measurements were carried out […]

Effects of CO2 and iron availability on rbcL gene expression in Bering Sea diatoms

Iron (Fe) can limit phytoplankton productivity in approximately 40% of the global ocean, including high-nutrient, low-chlorophyll (HNLC) waters. However, there is little information available on the impact of CO2-induced seawater acidification on natural phytoplankton assemblages in HNLC regions. Show More Summary

Temperature tolerance of different larval stages of the spider crab Hyas araneus exposed to elevated seawater pCO2

Exposure to elevated seawater PCO2 limits the thermal tolerance of crustaceans but the underlying mechanisms have not been comprehensively explored. Larval stages of crustaceans are even more sensitive to environmental hypercapnia and possess narrower thermal windows than adults. Show More Summary

The positive relationship between ocean acidification and pollution

Ocean acidification and pollution coexist to exert combined effects on the functions and services of marine ecosystems. Ocean acidification can increase the biotoxicity of heavy metals by altering their speciation and bioavailability. Show More Summary
