Small algae with great potential

Unique laboratory experiment shows rapid evolutionary adaptation to ocean acidification and warming. The single most important calcifying algae of the world’s oceans is able to simultaneously adapt to rising water temperatures and ocean acidification through evolution. Show More Summary

How do microbes respond to more acidic oceans? NSF funds Konstantinidis Study to find out

The National Science Foundation has awarded $366,000 to the School of Civil and Environmental Engineering’s Kostas Konstantinidis for a study illuminating how microbes adapt to oceans that are becoming more acidic as a result of climate change. As the amount of carbon dioxide in the atmosphere increases, the pH of seawater is dropping, but we […]

Multigenerational exposure to ocean acidification during food limitation reveals consequences for copepod scope for growth and vital rates

The copepod Calanus finmarchicus is a key component of northern Atlantic food webs, linking energy-transfer from phytoplankton to higher trophic levels. We examined the effect of different ocean acidification (OA) scenarios (i.e. ambient, 1080, 2080 and 3080 ?atm CO2) over two subsequent generations under limited food availability. Show More Summary

In 100 years, Maryland’s crab cakes might be shrimp cakes

Rising temperatures and a more acidic ocean may spell trouble for the Chesapeake Bay’s iconic crabs, oysters and fish. For centuries, the Chesapeake Bay has been a natural seafood factory along the East Coast, and that wealth of marine resources has shaped the area’s food culture and history—a 2011 Garden & Gun article referred to Maryland crab […]

Moss Landing researcher gets national grant to study ocean acidification

MOSS LANDING, Calif. – A researcher at the Moss Landing Marine Laboratories has received a $330,000 National Science Foundation grant to study the effects of ocean acidification on juvenile rockfish. Dr. Scott Hamilton is beginning his fourth year at Moss Landing Marine Labs. This new project will build upon his previous research on temperate marine […]

Consistent increase in dimethyl sulfide (DMS) in response to high CO2 in five shipboard bioassays from contrasting NW European waters (update)

The ubiquitous marine trace gas dimethyl sulfide (DMS) comprises the greatest natural source of sulfur to the atmosphere and is a key player in atmospheric chemistry and climate. We explore the short-term response of DMS production and cycling and that of its algal precursor dimethyl sulfoniopropionate (DMSP) to elevated carbon dioxide (CO2) and ocean acidification […]

Evidence that high pCO2 affects protein metabolism in tropical reef corals

Early life stages of the coral Seriatopora caliendrum were used to test the hypothesis that the depression of dark respiration in coral recruits by high pCO2 is caused by perturbed protein metabolism. First, the contribution of protein anabolism to respiratory costs under high pCO2 was evaluated by measuring the aerobic respiration of S. caliendrum recruits […]

Early-life exposure to climate change impairs tropical shark survival

Sharks are one of the most threatened groups of marine animals worldwide, mostly owing to overfishing and habitat degradation/loss. Although these cartilaginous fish have evolved to fill many ecological niches across a wide range of habitats, they have limited capability to rapidly adapt to human-induced changes in their environments.

Temperature is the evil twin: effects of increased temperature and ocean acidification on reproduction in a reef fish

Reproduction in many organisms can be disrupted by changes to the physical environment, such as those predicted to occur during climate change. Marine organisms face the dual climate change threats of increasing temperature and ocean acidification, yet no studies have examined the potential interactive effects of these stressors on reproduction in marine fishes. We used […]

Ocean acidification: the other problem with CO2

In our most recent virtual issue, you will find several research articles related to the theme, “Ocean Acidification: Causes, Consequences, and Cures”. It is part of an effort to organize ES&T content for readers and draw added attention to important findings. These papers will commence a virtual series known as an “ES&T Select”. Climate change […]

Aquatic bacteria withstands predicted acidity changes

Marine bacterial communities are highly resistant to elevated carbon dioxide levels and ocean acidification, a new study has found. The research, involving the University of Western Australia, the University of Newcastle upon Tyne and...Show More Summary

Webinar: “How to frame the issue of ocean acidification”, 24 September 2014

Wednesday, September 24, 7a-8am Alaska Time Sponsor: SOARCE webinar series, NOAA NMS and OAP Speaker: Alexis Bunten, The FrameWorks Institute Abstract: Did you ever wonder just what is in peoples’ heads that causes them to reach the wrong conclusions (despite the provision of accurate information) about the environmental issues that affect our lives? This webinar […]

MacArthur funds team bracing for climate change on the East Coast

Extreme weather events like 2012’s Hurricane Sandy have focused East Coasters on the scary realities of climate change. One group of researchers and regional nonprofits is teaming up to assess the threats and help communities prepare, with a $1 million grant from the MacArthur Foundation.(…) Ocean acidification will be one of the main focuses in […]

What will survive in hot, acidic oceans?

Marine losers abound in the hustling currents of warming and acidifying oceans. Trying to figure out which types of sea life, particularly those that form calcium carbonate-rich cells and exoskeletons, such as some plankton, corals, and shellfish, will thrive amid climate change can be like playing a high-stakes shell game. New research suggests that at […]

Adaptation of a globally important coccolithophore to ocean warming and acidification

Although ocean warming and acidification are recognized as two major anthropogenic perturbations of today’s oceans we know very little about how marine phytoplankton may respond via evolutionary change. We tested for adaptation to ocean warming in combination with ocean acidification in the globally important phytoplankton species Emiliania huxleyi. Show More Summary
