Scientists urge West Coast to prepare for approaching acidification (audio & text)

A group of scientists is warning that West Coast waters are quickly growing more acidic. They issued a report this week urging coastline states to adopt a plan to deal with the ocean’s rapidly changing chemistry. Seawater grows acidic when carbon dioxide seeps in from the atmosphere. The change can disorient fish, dissolve shells, and […]

Can corals keep up with ocean acidification?

An interdisciplinary team of researchers led by University of Delaware professors Wei-Jun Cai and Mark Warner has successfully measured both pH and carbonate ion concentration directly inside the calcifying fluid found in coral, an important...Show More Summary

Shrimps sound ocean acidity alarm

The effect of the sea absorbing increased carbon dioxide in the air has damaging consequences for the noisy snapping shrimp and marine life in coastal rock pools. The slow change in water chemistry as more and more atmospheric carbon dioxide dissolves in the sea and causes acidification could make the oceans much less noisy and […]

Ocean acidification’s effect on crab studied

Studies by federal fisheries researchers are documenting the affects ocean acidification are having on Alaska’s crab fisheries and the potential for all waters in Alaska to be in a corrosive situation for the year 2100. The big unanswered question, says Bob Foy, who oversees the shellfish assessment program at the Alaska Fisheries Science Center in […]

Role of deep convection on anthropogenic CO2 sequestration in the Gulf of Lions (northwestern Mediterranean Sea)

The most active deep convection area in the western Mediterranean Sea is located in the Gulf of Lions. Recent studies in this area provides some insights on the complexity of the physical dynamics of convective regions, but very little is known about their impacts on the biogeochemical properties. The CASCADE (CAscading, Surge, Convection, Advection and […]

Massachusetts tackling acidification

Count Massachusetts as the latest state to take a step towards fighting ocean acidification. Last week I attended a forum hosted by ocean champions Congressman Bill Keating (MA-9th) and Massachusetts State Representative Tim Madden (D-Nantucket) at the Woods Hole Research Center.  While there, I learned about a state bill sponsored by Rep. Madden to form […]

Buffering and amplifying interactions among OAW (ocean acidification & warming) and nutrient enrichment on early life-stage Fucus vesiculosus L. (Phaeophyceae) and their carry over effects to hypoxia impact

Ocean acidification and warming (OAW) are occurring globally. Additionally, at a more local scale the spreading of hypoxic conditions is promoted by eutrophication and warming. In the semi-enclosed brackish Baltic Sea, occasional upwelling...Show More Summary

Biochemical alterations induced in Hediste diversicolor under seawater acidification conditions

Seawater pH is among the environmental factors controlling the performance of marine organisms, especially in calcifying marine invertebrates. However, changes in non-calcifying organisms (including polychaetes) may also occur due to pH decrease. Show More Summary

Valuation of ocean acidification effects on shellfish fisheries and aquaculture

Ocean acidification has been recognized as a substantial stressor to some seawater calcifiers such as shellfish and corals with potentially significant social and economic consequences. Without mitigating atmospheric CO2 emissions, ocean acidification becomes greater over time. Show More Summary

West Coast prepares for ‘double whammy’ threat to ocean health

New action plan will help coastal businesses boost their resilience to future changes. Rising levels of acidity in the ocean and growing areas of low-oxygen waters are a “double whammy” threat for fishing industries, ecosystems and economies along the U.S. West Coast and Canada’s British Columbia, according to new report by a panel of experts […]

West Coast sientists weigh actions against ocean acidification and hypoxia

Ten years ago, I was finishing graduate school. I was becoming an expert on how carbon dioxide is stored in the world’s oceans, but – and this seems weird to me now – I hadn’t heard about ocean acidification. Hardly anyone had. Only a handful of scientists had started to realize that as the ocean […]

Coral and ocean acidification

9:39 a.m., April 4, 2016–An interdisciplinary team of researchers led by University of Delaware professors Wei-Jun Cai and Mark Warner has successfully measured both pH and carbonate ion concentration directly inside the calcifying fluid found in coral, an important development in the study of how ocean acidification will affect marine calcifying organisms such as corals […]

Microelectrode characterization of coral daytime interior pH and carbonate chemistry

Reliably predicting how coral calcification may respond to ocean acidification and warming depends on our understanding of coral calcification mechanisms. However, the concentration and speciation of dissolved inorganic carbon (DIC)Show More Summary

Photosynthetic responses of ‘Neosiphonia sp. epiphyte-infected’ and healthy Kappaphycus alvarezii (Rhodophyta) to irradiance, salinity and pH variations

Understanding the physiological condition of seaweeds as influenced by biotic and abiotic stress is vital from the perspective of massive expansion and sustainability of seaweed-based industries. The photosynthetic responses of Neosiphonia sp. Show More Summary

Intraspecific variation in physiological performance of a benthic elasmobranch challenged by ocean acidification and warming

Elucidating the combined effects of increasing temperature and ocean acidification on performance of fishes is central to our understanding of how species will respond to global climate change. Measuring the metabolic costs associated...Show More Summary

Interactive effects of ocean acidification and warming on coral reef associated epilithic algal communities under past, present-day and future ocean conditions

Epilithic algal communities play critical ecological roles on coral reefs, but their response to individual and interactive effects of ocean warming (OW) and ocean acidification (OA) is still largely unknown. We investigated growth,Show More Summary

Oxidative responsiveness to multiple stressors in the key Antarctic species, Adamussium colbecki: interactions between temperature, acidification and cadmium exposure

High-latitude marine ecosystems are ranked to be among the most sensitive regions to climate change since highly stenothermal and specially adapted organisms might be seriously affected by global warming and ocean acidification. TheShow More Summary

FerryBox-assisted monitoring of mixed layer pH in the Norwegian Coastal Current

The evaluation of marine carbonate system variability and the impacts of ocean acidification (OA) on coastal marine ecosystems increasingly rely on monitoring platforms capable of delivering near real-time in situ carbonate system observations. Show More Summary

Postdoc Position: Research Associate in Ocean Acidification/Chemical Oceanography, University of Washington

The University of Washington seeks to hire a postdoc to work on an ocean acidification experiment in French Polynesia under the guidance of Drs. Julian Sachs and Alex Gagnon. The successful candidate will deploy, maintain, and analyze data from a variety of physio-chemical sensors in addition to the analysis of alkalinity, dissolved inorganic carbon, and […]
