Eutrophication accelerates carbonate dissolution under high pCO2 condition in coral reef ecosystem

Incubation experiments were carried out to determine the effect of eutrophication on carbonate dissolution under high pCO2 (partial pressure of carbon dioxide) condition in coral reef ecosystem at Sesoko Island, Okinawa, Japan. 184 more words


Effect of ocean acidification and elevated fCO2 on trace gas production by a Baltic Sea summer phytoplankton community (update)

The Baltic Sea is a unique environment as the largest body of brackish water in the world. Acidification of the surface oceans due to absorption of anthropogenic CO2 emissions is an additional stressor facing the pelagic community of the already challenging Baltic Sea. 351 more words


Enhanced CO2 concentrations change the structure of Antarctic marine microbial communities

The impacts of anthropogenic enhancement of the partial pressure of carbon dioxide (pCO2) on marine organisms remain unclear, especially in Antarctic waters, which are predicted to be amongst the earliest and most severely affected by the consequent changes in ocean chemistry. 231 more words


Multi-taxon activity profiling reveals differential microbial response to reduced seawater pH and oil pollution

There is growing concern that predicted changes to global ocean chemistry will interact with anthropogenic pollution to significantly alter marine microbial composition and function. However, knowledge of the compounding effects of climate change stressors and anthropogenic pollution is limited. 275 more words


Assessing approaches to determine the effect of ocean acidification on bacterial processes (update)

Bacterial extracellular enzymes play a significant role in the degradation of labile organic matter and nutrient availability in the open ocean. Although bacterial production and extracellular enzymes may be affected by ocean acidification, few studies to date have considered the methodology used to measure enzyme activity and bacterial processes. 148 more words

I’m waking up but I can’t see a thing. I sit up and hit my head hard right away. I’m inside something! I kick and scream and push up and a lid flies open. 1,060 more words

Increasing CO2 changes community composition of pico- and nano-sized protists and prokaryotes at a coastal Antarctic site

Ocean acidification is a globally recognised phenomenon, but little is known of its impacts on Antarctic marine microbes. Here we report on the community response of pico- and nanophytoplankton, heterotrophic nanoflagellates (HNF) and prokaryotes (Archaea and Bacteria) to elevated CO2 during 3 minicosm experiments over the 2008/2009 summer at Davis Station, Antarctica. 191 more words
