Posted on OA: 2 Sep 2014 The susceptibility of crustose coralline algae (CCA) skeletons to dissolution is predicted to increase as oceans warm and acidify. Skeletal dissolution is caused by bioerosion from endolithic microorganisms and by chemical processes associated with undersaturation of carbonate minerals in seawater. Yet, the relative contribution

Ocean Acidification from Domestic to International
Posted on National Geographic: 2 Sep 2014 — Posted by Mark Spalding in Ocean Views on September 2, 2014 Observed and projected decline in global ocean pH, 1750-2100. Photo by Rhett A. Butler Since the industrial revolution began, we have released 2 trillion tons of carbon dioxide (CO2)
Ocean acidification reduces the crystallographic control in juvenile mussel shells
Posted on OA: 1 Sep 2014 Global climate change threatens the oceans as anthropogenic carbon dioxide causes ocean acidification and reduced carbonate saturation. Future projections indicate under saturation of aragonite, and potentially calcite, in the oceans by 2100. Calcifying organisms are those most at risk from such ocean acidification, as
Shell condition and survival of Puget Sound pteropods are impaired by ocean acidification conditions
Posted on OA: 31 Aug 2014 — Busch D. S., Maher M., Thibodeau P. & McElhany P., 2014. PLoS ONE 9(8): e105884. We tested whether the thecosome pteropod Limacina helicina from Puget Sound, an urbanized estuary in the northwest continental US, experiences shell dissolution and altered mortality rates when exposed
Size matters: plasticity in metabolic scaling shows body-size may modulate responses to climate change
Posted on OA: 29 Aug 2014 — Carey N. & Sigwart J. D., 2014. Biology Letters 10(8):20140408 Variability in metabolic scaling in animals, the relationship between metabolic rate (R) and body mass (M), has been a source of debate and controversy for decades. R is proportional to Mb, the precise
