Posted on OA: 21 May 2015 Dungeness crab (Cancer magister) eggs and larvae were exposed to laboratory controlled, low-pH seawater in an effort to assess current and predicted-future impacts of Ocean Acidification (OA) on hatching success, survival and growth. Treatment levels of pH ~8.0, ~7.5 and ~7.1 represented the

Impacts of ocean acidification on survival, growth, and swimming behaviours differ between larval urchins and brittlestars
Posted on OA: 15 May 2015 Ocean acidification (OA) is widely recognized as an increasing threat to marine ecosystems. Many marine invertebrates have dual-phase life cycles in which planktonic larvae connect and sustain otherwise disconnected benthic adult populations. Many planktonic larvae are particularly sensitive to environmental stresses including OA.
Climate change and dead zones
Posted on OA: 5 May 2015 Estuaries and coastal seas provide valuable ecosystem services but are particularly vulnerable to the co-occurring threats of climate change and oxygen-depleted dead zones. We analyzed the severity of climate change predicted for existing dead zones, and found that 94% of dead zones are
IOOS: Ocean acidification
Posted: 03 May 2013 Integrated Ocean Observing System, May 2013. Video. Since the start of the industrial revolution, the ocean has silently absorbed roughly 30% of the carbon dioxide that people generate through industry and agriculture. Now ocean chemistry of the seawater is rapidly changing in a process known as ocean acidification.
