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.
Environmental physiology of the jumbo squid, Dosidicus gigas (d’Orbigny, 1835) (Cephalopoda: Ommastrephidae): implications for changing climate
Posted on OA: 17 Apr 2015 Dosidicus gigas (d’Orbigny, 1835) is a large, active squid that undergoes a diel vertical migration in the Eastern Tropical and Temperate Pacific. It is a voracious predator on zooplankton and micronekton and supports a large fishery. It is further preyed upon by large
Changes in pteropod distributions and shell dissolution across a frontal system in the California Current System
Posted on OA: 17 Apr 2015 — Bednaršek N. & Ohman M. D., 2015. Marine Ecology Progress Series 523:93-103 We tested the sensitivity of the vertical distributions and shell dissolution patterns of thecosome pteropods to spatial gradients associated with an eddy-associated front in the southern California Current System. The
