The U.S. Northeast Continental Shelf marine ecosystem has warmed much faster than the global ocean and it is expected that this enhanced warming will continue through this century. Here, we used a high-resolution global climate model and historical observations of species distributions from a trawl survey to examine changes in ...
Ocean acidification (OA) is increasingly recognized as a major global problem. Despite the scientific evidence, economic assessments of its effects are few. This analysis is an attempt to perform a national and sub-national assessment of the economic impact of OA on mollusc production in Europe. We focus on mollusc production ...
Mussels are an ecologically and economically important taxon that attach to solid surfaces via the byssus. To date, little is known about the effects of ocean acidification (OA) on mussel byssal attachment and the underlying molecular byssal responses. This study demonstrated that after 1 week of exposure to acidified seawater, ...
The European Commission released a Science for Environment Policy brief about the prospective decline of the European shellfish industry due to ocean acidification. An excerpt: "Ocean acidification threatens marine ecosystems worldwide, but economic assessments of its impact are lacking. A recent study has predicted the future cost of ocean acidification on mollusc ...
The effects of ocean acidification on living marine resources present serious challenges for managers of these resources. An understanding of the ecosystem consequences of ocean acidification is required to assess tradeoffs among ecosystem components (e.g. fishery yield, protected species conservation, sensitive habitat) and adaptations to this perturbation. We used a ...
The continental shelf region off the west coast of North America is seasonally exposed to water with a low aragonite saturation state by coastal upwelling of CO2-rich waters. To date, the spatial and temporal distribution of anthropogenic CO2 (Canth) within the CO2-rich waters is largely unknown. Here we adapt the multiple ...
Acidification has sparked discussion about whether regulatory agencies should place coastal waters on the Clean Water Act 303(d) impaired water bodies list. Here we describe scientific challenges in assessing impairment with existing data, exploring use of both pH and biological criteria. Application of pH criteria is challenging because present coastal ...
Exponentially rising CO2 (currently ~400 µatm) is driving climate change and causing acidification of both marine and freshwater environments. CO2 directly affects acid–base and ion regulation, respiratory function and aerobic performance in aquatic animals. Elevated CO2 projected for end of this century (e.g. 800–1000 µatm) can also impact physiology, and have substantial ...
This four-page brochure provides an introduction to ocean and coastal acidification, its effects on marine life, why the Northeast is especially vulnerable, research priorities for the region, and what people can do to fight coastal acidification. The information in the brochure is adapted from NECAN's 2015 Oceanography article.
Impurities in indicator salts can significantly bias spectrophotometric pH determinations. In this work, two purified sulfonephthalein indicators, meta-cresol purple (mCP) and phenol red (PR), were tested for analysis of freshwater pH on the free hydrogen ion concentration scale. The work presented here is the first parallel comparison with two purified indicators used to ...
