The impact of oyster aquaculture on the estuarine carbonate system

  • Posted on: Thu, 07/14/2022 - 13:29
  • By: kcanesi

Abstract: Many studies have examined the vulnerability of calcifying organisms, such as the eastern oyster (Crassostrea virginica), to externally forced ocean acidification, but the opposite interaction whereby oysters alter their local carbonate conditions has received far less attention. We present an exploratory model for isolating the impact that net calcification and ...

A mineralogical record of ocean change: Decadal and centennial patterns in the California mussel

  • Posted on: Mon, 01/08/2018 - 11:51
  • By: kcanesi

Ocean acidification, a product of increasing atmospheric carbon dioxide, may already have affected calcified organisms in the coastal zone, such as bivalves and other shellfish. Understanding species’ responses to climate change requires the context of long-term dynamics. This can be particularly difficult given the longevity of many important species in ...

Economic impact of ocean acidification on shellfish production in Europe

  • By: jackie

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

  • Posted on: Wed, 02/22/2017 - 14:41
  • By: jackie

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, ...

Europe could suffer major shellfish production losses due to ocean acidification

  • By: jackie

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 ...

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

  • Posted on: Wed, 02/01/2017 - 15:03
  • By: jackie

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 ...

Overview of Coastal Acidification in the Northeast Region

  • Posted on: Tue, 10/25/2016 - 14:42
  • By: petert

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.
