Posted on EPOCA: 07 May 2013 — The orange cup coral is common on the California coast, where it thrives in the low pH waters of an upwelling regime. Results of this study suggest that feeding rate has a greater impact on calcification than pCO2. Ocean acidification, the assimilation of

High risk of extinction of benthic foraminifera in this century due to ocean acidification
Posted on EPOCA: 07 May 2013 Increased atmospheric CO2 concentrations lead to decreased pH and carbonate availability in the ocean (Ocean Acidification, OA). Carbon dioxide seeps serve as ‘windows into the future’ to study the ability of marine invertebrates to acclimatise to OA. We studied benthic foraminifera in sediments from shallow
A potential tool for high-resolution monitoring of ocean acidification
Posted on EPOCA: 02 May 2013 Current anthropogenic carbon dioxide emissions generate besides global warming unprecedented acidification rates of the oceans. Recent evidence indicates the possibility that ocean acidification and low oceanic pH may be a major reason for several mass extinctions in the past. However, a major bottleneck for
The marine carbon system and ocean acidification during Phanerozoic time
Posted on EPOCA: 02 May 2013 The global CO2-carbonic acid-carbonate system of seawater, although certainly a well-researched topic of interest in the past, has risen to the fore in recent years because of the environmental issue of ocean acidification (often simply termed OA). Despite much previous research, there remain pressing
Ocean Acidification in Washington State: Shallin Busch, PhD at TEDx The Evergreen State College
Published on May 1, 2013 Shallin Busch is a research ecologist at NOAA’s Northwest Fisheries Science Center (NWSFC). Her current research focuses on how ocean acidification may impact North Pacific ecosystems. Using the NWFSC ocean acidification experimental system, Dr. Busch applies ecological models to explore how acidification’s impacts on susceptible
