Marine species distribution shifts on the U.S. Northeast Continental Shelf under continued ocean warming

  • Posted on: Tue, 05/09/2017 - 12:30
  • By: jackie

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 ...

Economic impact of ocean acidification on shellfish production in Europe

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 ...

Ocean acidification decreases mussel byssal attachment strength and induces molecular byssal responses

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, ...

Assessing the effects of ocean acidification in the Northeast US using an end-to-end marine ecosystem model

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 ...

Chemical and biological impacts of ocean acidification along the west coast of North America

  • Posted on: Fri, 12/16/2016 - 10:17
  • By: jackie

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 ...

Water quality criteria for an acidifying ocean: Challenges and opportunities for improvement

  • Posted on: Tue, 11/01/2016 - 11:50
  • By: jackie

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 ...

Lessons from two high CO2 worlds – future oceans and intensive aquaculture

  • Posted on: Fri, 10/28/2016 - 13:40
  • By: jackie

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 ...

Coastal ocean acidification: The other eutrophication problem

  • Posted on: Wed, 03/30/2016 - 15:56
  • By: petert

Increased nutrient loading into estuaries causes the accumulation of algal biomass, and microbial degradation of this organic matter decreases oxygen levels and contributes towards hypoxia. A second, often overlooked consequence of microbial degradation of organic matter is the production of carbon dioxide (CO2) and a lowering of seawater pH. To ...

Ocean Acidification 2.0: Managing our Changing Coastal Ocean Chemistry

  • Posted on: Wed, 03/30/2016 - 13:47
  • By: petert

Ocean acidification (OA) is rapidly emerging as a significant problem for organisms, ecosystems, and human societies. Globally, addressing OA and its impacts requires international agreements to reduce rising atmospheric carbon dioxide concentrations. However, the complex suite of drivers of changing carbonate chemistry in coastal environments also requires regional policy analysis, ...
