Posted on EPOCA: 28 Aug 2012 The oceanic water south of Cabo San Lucas, Mexico is an oxygen minimum zone (OMZ.) OMZs lead to greater concentrations of carbon dioxide in the water. The OMZ near Cabo is expanding, causing an increase in CO2 concentrations and a steadily declining pH in

Analysis of Pacific oyster larval proteome and its response to high-CO2
Posted on EPOCA: 27 Aug 2012 — Published 27 August 2012 Science Most calcifying organisms show depressed metabolic, growth and calcification rates as symptoms to high-CO2 due to ocean acidification (OA) process. Analysis of the global expression pattern of proteins (proteome analysis) represents a powerful tool to examine these physiological symptoms
Seawater-pH measurements for ocean-acidification observations
Posted on EPOCA: 27 Aug 2012 The uptake of anthropogenic CO2 by the oceans since the onset of the industrial revolution is considered a serious challenge to marine ecosystems due to ensuing carbonate-chemistry changes (ocean acidification). Furthermore, the CO2 uptake is reducing the ocean’s capacity to absorb future CO2 emissions. In order to
Towards improved socio-economic assessments of ocean acidification’s impacts
Posted on EPOCA: 24 Aug 2012 — Published 24 August 2012 Science Ocean acidification is increasingly recognized as a component of global change that could have a wide range of impacts on marine organisms, the ecosystems they live in, and the goods and services they provide humankind. Assessment of these
Proof-of‐Concept: automated high‐frequency measurements of PCO₂ and TCO₂ and real‐time monitoring of the saturation state of calcium carbonate
Posted on EPOCA: 23 Aug 2012 — Burke Hales’ lab at Oregon State is working to produce instrumentation to achieve a high quality time series of carbonate data at sufficient resolution to be a powerful tool for coastal biogeochemical research, deepening our understanding of the impacts of ocean acidification.
