From Alan Trimble Hello Everyone, As July comes to a close we still have not seen a signficant Pacific Oyster spawning. Native oysters larval counts have begun dropping while setting has been good for the past four weeks (~10/shell per week). Clam larvae were abundant early in the month, but have

Bodega Ocean Acidification Research (BOAR) featured on EPOCA blog
Posted on EPOCA: 24 Jul 2011 Led by the research groups of Brian Gaylord, Tessa Hill, Ann Russell, and Eric Sanford, the Bodega Ocean Acidification Research (BOAR) consortium is examining spatial and temporal changes in seawater chemistry and the impacts of this variability on the ecology, physiology, and biomechanics
A comparison of the SNP variation in the calcification PMCA gene of Lottia gigantea between a Santa Barbara population and a more acidic Monterey Bay population
Posted on EPOCA: 24 Jul 2011 As the atmospheric levels of CO2 rise from human activity, the carbonic acid levels of the ocean increase, causing ocean acidification. This increase in acidity breaks down the calcified bodies that many marine organisms depend upon. Upwelling regions such as Monterey Bay in California
Erratum to the “Guide to Best Practices for Ocean Acidification Research and Data Reporting”

Impact of ocean warming and ocean acidification on marine invertebrate life history stages: Vulnerabilities and potential for persistence in a changing ocean
Posted on EPOCA: 21 Jul 2011 Global warming and increased atmospheric CO 2 are causing the oceans to warm, decrease in pH and become hypercapnic. These stressors have deleterious impacts on marine invertebrates. Increasing temperature has a pervasive stimulatory effect on metabolism until lethal levels are reached, whereas hypercapnia has
