Lithium isotopic composition of benthic foraminifera: a new proxy for paleo-pH reconstruction

The lithium isotopic composition of foraminifera is an established tracer of long-term changes in the global silicate weathering cycle, following the assumption that foraminifera faithfully record the lithium isotopic composition (?7Li) of seawater. Show More Summary

Ocean under global change: from science to school

This article includes a methodological proposal in which students collaborate with scientists in order to establish a significative series of data to know the impacts of Climate Change on a shellfish bank which represents the main socio-economic motor in a costal population of more than 14000 habitants live. This proposal explains the theoretical background of […]

Adjusting mitigation pathways to stabilize climate at 1.5 and 2.0 °C rise in global temperatures to year 2300

To avoid the most dangerous consequences of anthropogenic climate change, the Paris Agreement provides a clear and agreed climate mitigation target of stabilizing global surface warming to under 2.0 °C above preindustrial, and preferably closer to 1.5 °C. However, policy makers do not currently know exactly what carbon emissions pathways to follow to stabilize warming […]

Effects of seawater acidification and alkalization on the farmed seaweed, Pyropia haitanensis (Bangiales, Rhodophyta), grown under different irradiance conditions

Highlights • Either seawater acidification and alkalization or reduced light inhibited nitrogen metabolism of Pyropia haitanensis • Reduced irradiance alleviate negative effects of seawater alkalization on the algal growth and photosynthesis...Show More Summary

Analysis of recruitment of Pocillopora damicornis under climate change scenarios

Ocean warming and acidification are among the greatest threats to coral reefs, and severe bleaching events have become more common in recent decades, putting coral reefs  at risk of extinction. The loss of coral reefs would have a catastrophic cascading effect on all marine life and would mean a loss of one the world’s largest […]

Ocean acidification: herring could benefit from an altered food chain

New studies show complex effects of carbon dioxide on fish population As soon as they start life, it’s all about survival for juvenile young fish. They must learn to catch prey and to escape enemies. Additionally, at this stage of their lives they are highly sensitive to environmental factors such as temperature, oxygen and the […]

Food web changes under ocean acidification promote herring larvae survival

Ocean acidification—the decrease in seawater pH due to rising CO2 concentrations—has been shown to lower survival in early life stages of fish and, as a consequence, the recruitment of populations including commercially important species. Show More Summary

Could seaweed save California’s coast?

CSU faculty researchers find that marine plants could play a big role in reducing ocean acidification, a devastating side effect of climate change. ?One of the many devastating side effects of climate change is this: The planet’s seas are absorbing carbon dioxide from the atmosphere, making the water much more acidic. Ocean acidification (OA), as […]

The future of fishes and fisheries in the changing oceans

This paper aims to highlight the risk of climate change on coupled marine human and natural systems and explore possible solutions to reduce such risk. Specifically, it explores some of the key responses of marine fish stocks and fisheries to climate change and their implications for human society. It highlights the importance of mitigating carbon […]

Ocean acidification weakens coral skeletons

Coral reefs are under a barrage of threats. Ocean acidification alone could decrease the density of coral skeletons by up to 20%, with reefs close to the equator affected most. Declines in coral skeletal density could have wide-reaching impacts on reef structure. Reefs are a natural coastal defence, shielding coastlines from storms by dissipating much […]

The Ocean Acidification international Reference User Group releases a new Ocean Acidification guide

The Ocean Acidification international Reference User Group (OA-iRUG) has just released a new guide for Latin America and the Caribbean. It provides an overview of why Ocean Acidification is an issue, how it will impact ecosystems, and gives examples of actions to address it. The guide was released during the first regional Latin American OA-iRUG […]

Ocean acidification and desalination: climate-driven change in a Baltic Sea summer microplanktonic community

Helcom scenario modelling suggests that the Baltic Sea, one of the largest brackish-water bodies in the world, could expect increased precipitation (decreased salinity) and increased concentration of atmospheric CO2 over the next 100 years. Show More Summary

Request for proposal: blue carbon restoration project (The Ocean Foundation)

Deadline: 20 April 2018 The Ocean Foundation is seeking multi-year proposals under the Ocean Acidification Monitoring and Mitigation project for blue carbon restoration (seagrass, mangrove, or salt marsh) in the Pacific Islands. The Ocean Foundation will fund ONE proposal for the region with a budget not to exceed $90,000 US. The Ocean Foundation is soliciting […]

Column: Federal budget cuts could harm ocean, Chesapeake Bay

The past 10 years have witnessed significant progress toward understanding local and global effects of climate change, thanks largely to the National Oceanic and Atmospheric Administration. However, we’re now in danger of taking a big step in the wrong direction. President Donald Trump’s latest budget proposal cuts NOAA’s budget by $1 billion. It eliminates all […]

Townsend leading research as part of NOAA Ocean Acidification Program

Research led by University of Maine Professor of Oceanography David Townsend is part of NOAA’s newly announced Ocean Acidification Program. Townsend is working in collaboration with UMaine School of Marine Sciences researchers Larry Mayer, Aaron Strong and Damian Brady; Joe Salisbury of the University of New Hampshire; and colleagues from Friends of Casco Bay, Northeast […]

Assess, anticipate, adapt: vulnerability and responses to ocean acidification

There are areas in the United States where marine resources and the communities and industries that depend on them are particularly vulnerable to the impacts of ocean acidification. In three US regions, our understanding of vulnerability is being advanced by coupling ocean and social science data to equip communities and industries with the information needed […]

Job opportunity: postdoctoral position on marine community ecology-functional biodiversity and environmental change

Description The postdoc position has a focus on marine community ecology-functional biodiversity and environmental change and is a part of 4Oceans, a recently funded project by “Make Our Planet Great Again”. The Postdoctoral Researcher will be based at Laboratoire d’Oce?anographie de Villefranche, France. Please note that the deadline for submission for the two phases of […]

Health of crucial plants at the base of marine food chains disrupted by ocean acidification

New research out of Rutgers University-Newark, University of California San Diego, and the J. Craig Venter Institute shows that increased CO2 in oceans interfere with necessary iron intake in phytoplankton, which support ocean food chains and fisheries and help moderate CO2 levels. A team led by scientists from the Scripps Institution of Oceanography at the University of […]

‘Game changer’: new vulnerability to climate change in ocean food chain

Excessive rates of carbon dioxide affect the health of key micro-organisms in the oceans, potentially undermining the base of critical marine food chains, according to new research by US scientists. A team of researchers from the Scripps Institution of Oceanography and the J. Craig Venter Institute (JCVI) applied techniques from the emerging field of synthetic […]

Key biological mechanism is disrupted by ocean acidification

A team led by scientists from Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) has demonstrated that the excess carbon dioxide added to the atmosphere through the combustion of fossil fuels interferes with the health of phytoplankton which form the base of marine food webs.
