Acidification des océans : la menace invisible (text and videos; in French)

La menace est invisible. Pourtant c’est l’une des conséquences du réchauffement climatique, qui pourrait modifier en profondeur la biodiversité marine : l’acidification de la mer. Un phénomène déjà en marche même si en Bretagne, les effets ne se feraient sentir que vers 2080. Chaque mois, les scientifiques de la station marine de Roscoff se rendent […]

Ocean acidification affects larval swimming in Ostrea lurida but not Crassostrea gigas

The effects of ocean acidification (OA), which results from increased CO2 emissions, are of particular concern for calcifying marine organisms. In marine invertebrates, the larval stages are generally considered the most vulnerable to the effects of OA and many recent studies show negative impacts of OA on early developmental stages of calcifying marine invertebrates. I […]

Climate change: Atlantic plankton bloom reflects soaring carbon dioxide levels, scientists say

Scientists say growth of coccolithophores, a microscopic marine alga, could be ‘canary in the coalmine’ for climate change. A microscopic marine alga with a shell-like skeleton has increased more than tenfold in the North Atlantic over the past 50 years in response to rising levels of carbon dioxide, scientists have discovered. The dramatic “bloom” of […]

Multidecadal increase in North Atlantic coccolithophores and the potential role of rising CO2

As anthropogenic CO2 emissions acidify the oceans, calcifiers generally are expected to be negatively affected. However, using data from the Continuous Plankton Recorder, we show that coccolithophore occurrence in the North Atlantic increased from ~2 to over 20% from 1965 through 2010. We used Random Forest models to examine >20 possible environmental drivers of this […]

Two decades of inorganic carbon dynamics along the West Antarctic Peninsula (update)

We present 20 years of seawater inorganic carbon measurements collected along the western shelf and slope of the Antarctic Peninsula. Water column observations from summertime cruises and seasonal surface underway pCO2 measurements provide unique insights into the spatial, seasonal, and interannual variability in this dynamic system.

An automated monitoring and control system for flow-through co-cycling hypoxia and pH experiments

Acidification research has exploded in recent years, however, experiments testing effects of co-cycling hypoxia and pH on ecological and physiological processes are rare, despite the pervasiveness and potential importance of co-varying fluctuations in these parameters. Show More Summary

CO2 Modeller brings climate change and emissions targets within touching distance

Scientists and computer engineers at the University of Southampton have developed an interactive climate app – CO2 Modeller – which can fit in your pocket and help you to gauge the future effects of carbon emissions around key sensitivities of the Earth’s climate. The new app, CO2 Modeller, provides an interactive tool to allow anyone […]

OA-ICC technical meeting on the management of biological response to ocean acidification data, 17-18 November 2015, Monaco

The IAEA Ocean Acidification International Coordination Centre (OA-ICC) organized a technical meeting on the management of biological response data related to ocean acidification, focusing specifically on the discovery and access of these data via a common data portal. The meeting was hosted at the IAEA Environment Laboratories in Monaco, November 17 – 18, 2015 and […]

Deadline for applications: 21 December 2015! Host institute: Inhaca Marine Biology Research Station, Inhaca Island, Mozambique Dates: 8–12 February 2016 Organizers: The University of Gothenburg, Sweden; The Global Ocean Acidification Observing Network (GOA-ON). Show More Summary

Sensitivity of Mediterranean bivalve mollusc aquaculture to climate change and ocean acidification: results from a producers’ survey

Human-induced climate change and ocean acidification are global environmental phenomena with a common driver: anthropogenic emissions of carbon dioxide. Both processes potentially threaten the Mediterranean bivalve mollusc aquaculture sector, which is economically relevant to several regions and countries. Show More Summary

Effects of elevated CO2 on early life history development of the yellowtail kingfish, Seriola lalandi, a large pelagic fish

An increasing number of studies have examined the effects of elevated carbon dioxide (CO2) and ocean acidification on marine fish, yet little is known about the effects on large pelagic fish. We tested the effects of elevated CO2 on the early life history development and behaviour of yellowtail kingfish, Seriola lalandi. Eggs and larvae were […]

Bacterioplankton community resilience to ocean acidification: evidence from microbial network analysis

Ocean acidification (OA), caused by seawater CO2 uptake, has significant impacts on marine calcifying organisms and phototrophs. However, the response of bacterial communities, who play a crucial role in marine biogeochemical cycling, to OA is still not well understood. Show More Summary

Marine microzooplankton are indirectly affected by ocean acidification through direct effects on their phytoplankton prey

To date there is little evidence to suggest that marine microzooplankton are directly affected by ocean acidification (OA), and few studies have explored indirect effects of OA on microzooplankton. Microzooplankton grazing behavior is...Show More Summary

Temperature control and carbonate system manipulation in a land-based mesocosm experiment

Warming and acidification of the oceans are two major drivers of climate change. Mesocosm facilities are a powerful tool for studying the impact of warming and acidification on planktonic ecosystems. This study presents one of the few existing systems for controlling temperature in outdoor mesocosm enclosures. Two temperature targets (25, 28°C) were maintained with very […]

Laboratory simulation system, using Carcinus maenas as the model organism, for assessing the impact of CO2 leakage from sub-seabed injection and storage

The capture and storage of CO2 in sub-seabed geological formations has been proposed as one of the potential options to decrease atmospheric CO2 concentrations in order to mitigate the abrupt and irreversible consequences of climate change. Show More Summary

Comparative studies on the effects of seawater acidification caused by CO2 and HCl enrichment on physiological changes in Mytilus edulis

The present medium term (21 d) study was performed to evaluate the effects of HCl or CO2-induced acidified seawater (pH 7.7, 7.1 or 6.5; control: pH 8.1) on the physiological responses of the blue mussel, Mytilus edulis, at different levels of biological organization. The results demonstrate that: (1) either HCl or CO2 enrichment had significant […]
