Pacific oysters gain from IOOS® data About six years ago, production at some Pacific Northwest oyster hatcheries began declining at an alarming rate, posing severe economic impact and challenging a way of life held by shellfish growers for more than 130 years. By 2008, the oyster harvest at Whiskey Creek,

Land-sea carbon and nutrient fluxes and coastal ocean CO2 exchange and acidification: Past, present, and future
Posted on the EPOCA blog, March 28, 2011 Epochs of changing atmospheric CO2 and seawater CO2-carbonic acid system chemistry and acidification have occurred during the Phanerozoic at various time scales. On the longer geologic time scale, as sea level rose and fell and continental free board decreased and increased, respectively,
Effects of ocean acidification on macroalgal communities
From EPOCA blog, posted March 21, 2011 — Porzio L., Buia M. C., & Hall-Spencer J. M., in press. Effects of ocean acidification on macroalgal communities. Journal of Experimental Marine Biology and Ecology doi:10.1016/j.jembe.2011.02.011. There are high levels of uncertainty about how coastal ecosystems will be affected by rapid
Examining the impacts of ocean acidification
From Skeptical Science — getting skeptical about global warming skepticism Posted: 17 Mar 2011 08:55 AM PDT The current debate on the connection between CO2 emissions and climate change has largely overlooked an independent and equally serious problem, the increasing acidity of our oceans. Last December, the respected journal “Oceanography” published projections (see
Rising ocean temperatures will impact sea urchins and abalone
Findings from Australian study Marine abalone and sea urchins in Sydney Harbour will not develop normal skeletons if the ocean continues to warm and acidify as predicted, a study has found. Such impaired development could have a dramatic effect on the survival of these economically and ecologically important sea creatures.
