Tiny but tough: calcification in marine phytoplankton

Coccolithophores stand out from other marine phytoplankton in their ability to form calcified plates. Why is it beneficial for coccolithophores to calcify and how may these plates hold up under future ocean conditions? Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of Oceanography. I am interested in […]

Do coral reefs help fight climate change?

Coral reefs are called the rainforests of the sea for their stunning biodiversity. But can they, like forests on land, absorb CO2 and help reduce global warming? Michael PhilbenI recently completed a PhD in Marine Science at the University of South Carolina and am now a postdoc at Memorial University of Newfoundland. I research the […]

Consummate Corals: resilience in an acidifying ocean

Gloom and doom has been the dominant message associated with climate change. However, it is important to remember that when faced with change, not all species and ecosystems are created equal. Recently, researchers have found that several species of cold-water corals are quite resilient to ocean acidification. Gordon OberPostdoctoral Researcher, Claremont McKenna College I am […]

Is Aragonite Saturation State (Ωa) the Best Way to Describe Calcification Rate?

Nearly every scientific report concerning the effects of ocean acidification on coral reefs describes changes in calcification as a function of the aragonite saturation state (Ωa). Is this the best parameter that we can use to represent calcification condition? Are there any other options? Caoxin SunCaoxin is a graduate student in the Graduate School of […]

Coral Reefs Suffering from Ocean Acidification

Researchers investigated natural trends in carbonate chemistry of the Davies Reef flat in the central Great Barrier Reef on diel and seasonal timescales. They found the reef flat is below a calcification threshold, which implies that a transition in the reef may occur from a state of net calcification to dissolution, around 26.9% of the […]
