Acidic ocean water makes sea snails smaller

Sea snails prefer to be smaller when they are stressed by high CO2 levels. New findings explain why marine species that survived previous mass extinction events were much smaller – a phenomenon known as the ‘Lilliput effect’. Sea snails respond with stunted growth when they are exposed to the high levels of CO2 we can […]

Back in the fjord – Kiel marine scientists investigate responses of the plankton community to ocean acidification in a field experiment off Norway

08 May 2015/Bergen, Kiel. In a new experiment with the KOSMOS mesocosms, scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel address key questions about the impacts of ocean acidification on the food web and biogeochemical cycling. As part of this study, which runs until the end of June in Raunefjord, Bergen (Norway), the researchers […]

Two decades of inorganic carbon dynamics along the Western Antarctic Peninsula

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 of the dynamic system.

What’s like INSIDE our Kelp Forest exhibit? Staffer Patrick Webster gives us a look in this cool clip taken while window cleaning. Twice a day you can tune in live to our Kelp Forest feeding program and watch divers hand-feed sharks, fishes and other animals. If you’re lucky, a wolf-eel will emerge to gulp some squid or fish!

Enhanced pH up-regulation enables the cold-water coral Lophelia pertusa to sustain growth in aragonite undersaturated conditions

Cold-water corals are important habitat formers in deep-water ecosystems and at high latitudes. Ocean acidification and the resulting change in aragonite saturation are expected to affect these habitats and impact coral growth. Counter to expectations, the impact of saturation changes on the deep water coral Lophelia pertusa has been found to be less than expected, […]

Acidification of the Mediterranean sea from anthropogenic carbon penetration

This study presents an estimation of the anthropogenic CO2 (CANT) concentrations and acidification (?pH=pH2013 – pHpre-industrial) in the Mediterranean Sea, based upon hydrographic and carbonate chemistry data collected during the May 2013 MedSeA cruise. Show More Summary

“Lethal Seas”: Airing 13 May 2015 at 9 pm on PBS

A unique coral garden in Papua New Guinea shows what the future may hold as oceans acidify. A deadly recipe is brewing that threatens the survival of countless creatures throughout Earth’s oceans. For years, we’ve known that the oceans absorb about a quarter of the carbon dioxide in our atmosphere. But with high carbon emissions […]

Reconsidering the role of carbonate ion concentration in calcification by marine organisms

Marine organisms precipitate 0.5–2.0 Gt of carbon as calcium carbonate (CaCO3) every year with a profound impact on global biogeochemical element cycles. Biotic calcification relies on calcium ions (Ca2+) and generally on bicarbonate ions (HCO3?) as CaCO3 substrates and can be inhibited by high proton (H+) concentrations. Show More Summary

An integrated assessment model for helping the United States sea scallop (Placopecten magellanicus) fishery plan ahead for ocean acidification and warming

Ocean acidification, the progressive change in ocean chemistry caused by uptake of atmospheric CO2, is likely to affect some marine resources negatively, including shellfish. The Atlantic sea scallop (Placopecten magellanicus) supports one of the most economically important single-species commercial fisheries in the United States. Show More Summary

How California is mobilizing boundary chains to integrate science, policy and management for changing ocean chemistry

Boundary organizations play an important role in stabilizing interactions between science and nonscience. In this paper we focus on how boundary organizations not only serve a variety of actors across a complex science-policy landscape, but also actively shape that landscape over time through process, institution building, and partnerships building.

Lecture: “Responses of marine organisms to global change”, 12 May 2015,

Presented by Dr Sue-Ann Watson, Research Associate at the ARC Centre of Excellence for Coral Reef Studies at James Cook University Date & time: Tuesday, 12 May 2015, 11:30-12:30 Location: Building 19, Room #106, James Cook University, Townsville, Australia Abstract Global change, including ocean acidification and warming, poses a serious threat to marine life.

Ocean acidification discussion on tap at Corvallis Science Pub, 11 May 2015, Corvallis, Oregon

CORVALLIS, Ore. – It’s been called the “evil twin” of climate change. As the oceans absorb carbon dioxide from the atmosphere and surface waters become more acidic, changes to marine ecosystems are likely to follow. Coral reefs, shell-forming organisms and the fish and marine mammals that depend on them are at risk. At the May […]

Modelling coral calcification accounting for the impacts of coral bleaching and ocean acidification (update)

Coral reefs are diverse ecosystems that are threatened by rising CO2 levels through increases in sea surface temperature and ocean acidification. Here we present a new unified model that links changes in temperature and carbonate chemistry to coral health. Changes in coral health and population are explicitly modelled by linking rates of growth, recovery and […]
