Oyster farmers worried as climate change lowers ocean pH

Long before scientists and shellfish companies were aware of what was happening, a silent killer began devastating California’s oyster industry. About 10 years ago, baby oysters, or spat, began to die at an alarming rate. Farms along the West Coast lost more than half of their bivalves before they reached maturity, creating a shortage of […]

Effects of “reduced” and “business-as-usual” CO2 emission scenarios on the algal territories of the damselfish Pomacentrus wardi (Pomacentridae)

Turf algae are a very important component of coral reefs, featuring high growth and turnover rates, whilst covering large areas of substrate. As food for many organisms, turf algae have an important role in the ecosystem. Farming damselfish can modify the species composition and productivity of such algal assemblages, while defending them against intruders. Like […]

Energy metabolism and cellular homeostasis trade-offs provide the basis for a new type of sensitivity to ocean acidification in a marine polychaete at a high-CO2 vent: adenylate and phosphagen energy pools versus carbonic anhydrase

Species distributions and ecology can often be explained by their physiological sensitivity to environmental conditions. Whilst we have a relatively good understanding of how these are shaped by temperature, for other emerging drivers, such as PCO2 we know relatively little. Show More Summary

Eggs-cetera Another one of our nifty nautiluses laid an egg in its Tentacles exhibit. That’s the 10 th egg from this group of cephalopods since this special exhibition opened in March 2015. Aquarist Bret Grasse and his colleagues are caring for six eggs behind the scenes, while four are developing on exhibit. Show More Summary

Turf algal epiphytes metabolically induce local pH increase, with implications for underlying coralline algae under ocean acidification

The presence of epiphytic turf algae may modify the effects of ocean acidification on coralline algal calcification rates by altering seawater chemistry within the diffusive boundary layer (DBL) above coralline algal crusts. We used microelectrodes to measure the effects of turf algal epiphytes on seawater pH and the partial pressure of oxygen (pO2) within the […]

Natural variability in the surface ocean carbonate ion concentration

We investigate variability in the surface ocean carbonate ion concentration ([CO32?]) on the basis of a long control simulation with a fully-coupled Earth System Model. The simulation is run with a prescribed, pre-industrial atmospheric...Show More Summary

Skeletal mineralogy of coral recruits under high temperature and pCO2

Aragonite, which is the polymorph of CaCO3 precipitated by modern corals during skeletal formation, has a higher solubility than the more stable polymorph calcite. This higher solubility leaves animals that produce aragonitic skeletons more vulnerable to anthropogenic ocean acidification. Show More Summary

Expression of calcification and metabolism-related genes in response to elevated pCO2 and temperature in the reef-building coral Acropora millepora

Declining health of scleractinian corals in response to deteriorating environmental conditions is widely acknowledged, however links between physiological and functional genomic responses of corals are less well understood. Here we explore...Show More Summary

Assessing the impact of diagenesis on ?11B, ?13C, ?18O, Sr/Ca and B/Ca values in fossil planktic foraminiferal calcite

The geochemical composition of foraminiferal tests is a valuable archive for the reconstruction of paleo-climatic, -oceanographic and -ecological changes. However, dissolution of biogenic calcite and precipitation of inorganic calcite...Show More Summary

An undersea volcano previews a terrifying future for the world’s oceans

Scientists discover an area in the South Pacific where high levels of carbon dioxide have created dead zones where healthy coral reefs should be. In a remote area of the South Pacific, nature has opened a window on the most likely future for the world’s tropical coral reefs unless nations radically cut fossil fuel emissions. […]

Bacterial extracellular enzyme activity in a future ocean

Heterotrophic bacteria are recognised as vital components in the cycling and regulation of inorganic and organic matter in the ocean. Research to date indicates that future changes in ocean conditions may influence bacterial extracellular enzyme hydrolysis rates, which could affect the strength of the microbial loop and consequently organic matter export. The aim of this […]

Arctic carbon cycle: patterns, impacts and possible changes

Land and ocean uptake and release of carbon dioxide and methane play important roles for regulating their atmospheric concentrations. For example, over the industrialised period the terrestrial biosphere and global oceans have acted as net sinks of carbon dioxide, having absorbed CO2 corresponding to more than 50 % of the accumulated emissions from fossil fuel […]

Do increased temperature and CO2 levels affect the growth, photosynthesis, and respiration of the marine macroalga Pyropia haitanensis (Rhodophyta)? An experimental study

The marine red macroalgae Pyropia haitanensis (Rhodophyta) were cultured at 18 and 22°C, and at 390 and 1,000 ppm CO2, to examine the potential influence of global change on this commercially important species. The results showed that elevated CO2 or temperature hardly affected the relative growth rate. However, the maximal photochemical yield (F v/F m) […]

Experimental evolution gone wild

Because of their large population sizes and rapid cell division rates, marine microbes have, or can generate, ample variation to fuel evolution over a few weeks or months, and subsequently have the potential to evolve in response to global change. Here we measure evolution in the marine diatom Skeletonema marinoi evolved in a natural plankton […]
