Chemical and biological impacts of ocean acidification along the west coast of North America

The continental shelf region off the west coast of North America is seasonally exposed to water with a low aragonite saturation state by coastal upwelling of CO2-rich waters. 322 more words

Shell dissolution observed in Limacina helicina antarctica from the Ross Sea, Antarctica: paired shell characteristics and in situ seawater chemistry

The euthecosome (shelled) Antarctic pteropod, Limacina helicina antarctica, is a dominant member of the Southern Ocean macrozooplankton community, and due to its aragonitic shell, is thought to be particularly vulnerable to ocean acidification and under-saturation conditions that are predicted in the future. 285 more words

The metabolic response of thecosome pteropods from the North Atlantic and North Pacific oceans to high CO2 and low O2 (update)

As anthropogenic activities directly and indirectly increase carbon dioxide (CO2) and decrease oxygen (O2) concentrations in the ocean system, it becomes important to understand how different populations of marine animals will respond. 261 more words

Ocean acidification challenges copepod phenotypic plasticity (update)

Ocean acidification is challenging phenotypic plasticity of individuals and populations. Calanoid copepods (zooplankton) are shown to be fairly plastic against altered pH conditions, and laboratory studies indicate that transgenerational effects are one mechanism behind this plasticity. 206 more words

Expedition to study scale of microplastics on Atlantic's smallest creatures

Scientists will sail from the UK to the Falkland Islands to study the level of microplastic pollution on tiny zooplankton at the bottom of the food chain. (Theguardian.com, 19/09/2016)
