The egg production rate, hatching success, and respiration of a Mediterranean copepod were not affected by ocean acidification conditions. Warming and food availability did have some effects. (Laboratory study)

Understanding ocean acidification impacts on organismal to ecological scales

Ocean acidification (OA) research seeks to understand how marine ecosystems and global elemental cycles will respond to changes in seawater carbonate chemistry in combination with other environmental perturbations such as warming, eutrophication, and deoxygenation. This paper discusses the effectiveness and limitations of current research approaches used to address this goal. ...

This report describes climatological mean monthly distributions of pH, total carbon dioxide concentration, and the degree of CaCO3 saturation for the global surface ocean waters (excluding coastal areas) to depths of approximately 160 feet (50 meters).

Future oceanic warming and acidification alter immune response and disease status in a commercial shellfish species, Mytilus edulis L.

Ocean acidification and/or warmer temperatures may affect immune response, parasite abundance and diversity, and bacterial infection of blue mussels. (Laboratory study)

Food supply and seawater pCO2 impact calcification and internal shell dissolution in the blue mussel Mytilus edulis

  • Posted on: Mon, 06/13/2016 - 05:56

Blue mussels from the Baltic Sea grew less when raised for seven weeks under ocean acidification conditions and with limited food algae. Corrosion of the internal shell surface occurred at a range of ocean acidification levels when food supply was low. When food supply was high, corrosion occurred only in ...

Multigenerational exposure to ocean acidification during food limitation reveals consequences for copepod scope for growth and vital rates

The copepod Calanus finmarchicus had reduced growth, development, and fecundity when exposed to ocean acidification conditions. However, offspring in the next generation did not have delayed development, suggesting that the species may have an ability to adapt to ocean acidification. The results also suggest that in a more acidified ocean ...

Impact of ocean acidification on escape performance of the king scallop, Pectan maximus from Norway

  • Posted on: Mon, 06/13/2016 - 05:56
  • By: Anonymous

King scallops in Norway clapped their shells (an escape response) with less force after being exposed to ocean acidification conditions for at least 30 days. The number of claps was unchanged, however. Ocean acidification also narrows the thermal tolerance range of scallops, resulting in elevated vulnerability to temperature extremes. These ...
