Impacts of elevated pCO2 on trace gas emissions in two microalgae: Phaeocystis globosa and Nitzschia closterium

The potential impacts of seawater acidification on the concentrations of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP), dissolved acrylic acid (AAd) and various volatile halocarbons, including CH3Cl, CHBr3, CH2Br2, CHBr2Cl,...Show More Summary

Assessing ocean acidification and carbon cycle perturbations during the end-Permian extinction using boron isotopes

The Permian-Triassic mass extinction represents the most severe environmental crisis in Earth’s history, which dictated the course for evolution of life until today. Volcanism from Siberian traps played a significant role involving a...Show More Summary

Global perturbation of the marine calcium cycle during the Permian-Triassic transition

A negative shift in the calcium isotopic composition of marine carbonate rocks spanning the end-Permian extinction horizon in South China has been used to argue for an ocean acidification event coincident with mass extinction. This interpretation...Show More Summary

Vertical distribution and diurnal migration of atlantid heteropods

Understanding the vertical distribution and migratory behaviour of shelled holoplanktonic gastropods is essential in determining the environmental conditions to which they are exposed. This is increasingly important in understanding the effects of ocean acidification and climate change. Show More Summary

Interactive effects of ocean acidification and temperature on PSII function and protection in the diatom Thalassiosira pseudonana

Highlights • Photoinactivation was induced by multiple environmental changes. • Higher pCO2 alleviates the negative effect of temperature rise on PSII. • Ocean acidification stimulates much faster PsbA removal. • NPQ and SOD induction showed different response to temperature. Show More Summary

Community-level sensitivity of a calcifying ecosystem to acute in situ CO2 enrichment

The rate of change in ocean carbonate chemistry is a vital determinant in the magnitude of effects observed. Benthic marine ecosystems are facing an increasing risk of acute CO2 exposure that may be natural or anthropogenically derived (e.g. Show More Summary

Growth performance and survival of larval Atlantic herring, under the combined effects of elevated temperatures and CO2

In the coming decades, environmental change like warming and acidification will affect life in the ocean. While data on single stressor effects on fish are accumulating rapidly, we still know relatively little about interactive effects of multiple drivers. Of particular concern in this context are the early life stages of fish, for which direct effects […]

The Arctic picoeukaryote Micromonas pusilla benefits synergistically from warming and ocean acidification

In the Arctic Ocean, climate change effects such as warming and ocean acidification (OA) are manifesting faster than in other regions. Yet, we are lacking a mechanistic understanding of the interactive effects of these drivers on Arctic primary producers. In the current study, one of the most abundant species of the Arctic Ocean, the prasinophyte […]

Influence of bacteria on shell dissolution in dead gastropod larvae and adult Limacina helicina pteropods under ocean acidification conditions

Ocean acidification (OA) increases aragonite shell dissolution in calcifying marine organisms. It has been proposed that bacteria associated with molluscan shell surfaces in situ could damage the periostracum and reduce its protective function against shell dissolution. Show More Summary

Intraspecific variation in the response of the scleractinian coral Acropora digitifera to ocean acidification

To examine the possible variation in responses of corals to ocean acidification (OA) among populations, we compared the sensitivity of two Okinawan populations (Sesoko and Bise) of the scleractinian coral Acropora digitifera to high pCO2. Show More Summary

The Ocean Film Challenge

Filmmakers have the power to change the trajectory of human life on our water planet — from destruction to revitalization! Submit a short film for the Ocean Film Challenge, 7 minutes or under, on the impact humans have on the ocean and the actions individuals can take to save the ocean … and the humans who […]

Ocean acidification threatens our shellfish

The Massachusetts legislature is current considering a number of bills regarding ocean acidification. If passed into law, the bills will establish a special commission or task force to study the effects of coastal and ocean acidification on coastal communities, fishing and aquaculture industries, and local commercially-harvested species. Show More Summary

New platform for ocean acidification information exchange

Catalyzing response to ocean acidification through collaboration and information sharing The Ocean Acidification Information Exchange and its members advance understanding of ocean acidification through collaboration and information sharing to better prepare communities to respond and adapt to acidification.

The future of coral reefs subject to rapid climate change: lessons from natural extreme environments

Global climate change and localized anthropogenic stressors are driving rapid declines in coral reef health. In vitro experiments have been fundamental in providing insight into how reef organisms will potentially respond to future climates. Show More Summary

Acidified seawater increases accumulation of cobalt but not cesium in manila clam Ruditapes philippinarum

Highlights • Co accumulation in clam Ruditapes philippinarum might double due to ocean acidification. • The highest CF of cobalt was observed in acidified seawater (pH:7.5). • The longest Tb1/2 of cobalt was seen in moderately acidified seawater (pH:7.8). Show More Summary

Working group releases report evaluating the use of nature-based strategies to combat ocean acidification

SACRAMENTO – After months of research and deliberation, a working group convened by the California Ocean Protection Council and California Ocean Science Trust on Tuesday released a report analyzing seagrass and kelp as an ocean acidification management tool in California. Show More Summary

Emerging understanding of seagrass and kelp as an ocean acidification management tool in California

This report communicates emerging scientific understanding of the ability of seagrass and kelp to ameliorate ocean acidification (OA) in a California-specific context. It provides guidance on next steps for the State as it considers future nature-based actions to reduce the negative impacts of OA in California and beyond. OVERVIEW California is exploring local and regional […]

Expression of homing endonuclease gene and insertion-like element in sea anemone mitochondrial genomes: lesson learned from Anemonia viridis

Highlights • We report complete mitochondrial genome sequences and corresponding mito-transcriptomes of the two related sea anemone species Anemonia viridis and Anemonia majano • We describe structural features of group I introns in the NADH dehydrogenase 5 gene and the cytochrome oxidase I (COI) gene, the latter containing a homing endonuclease gene • We provide […]
