August 7, 2017 Global climate change is increasing ocean temperature and partial pressure of CO2 (pCO2) in coastal and marine ecosystems. Research in this field has largely focused on how limited CO32− availability and low pH adversely affect early development of calcifying organisms, but noncalcareous organisms are comparatively

The effects of ocean warming and acidification on seaweed growth and urchin grazing
Forward: This thesis shows that purple urchins increase feeding rates by about 500% when exposed to acidified conditions that are currently occurring in Northern California during spring upwelling season. (see figure 8 below) http://broncoscholar.library.cpp.edu/bitstream/handle/10211.3/194019/BriggsLauren_Thesis2017.pdf?sequence=4 No wonder the kelp is all gone! Of course 150 purples per square meter can do
New model reveals how ocean acidification challenges tiny sea snails off U.S. West Coast
July 17, 2017 A tiny sea snail, sometimes called a sea butterfly because of how it flutters about traveling the ocean currents, is part of the diet for such valuable fish as salmon and cod off the U.S West Coast. A new study models the journey of this delicate
Spatial patterns of Anchoveta (Engraulis ringens) eggs and larvae in relation to pCO2 in the Peruvian upwelling system
July 13, 2017 Sara G. Shen, Andrew R. Thompson, Jonathan Correa, Peer Fietzek, Patricia Ayo´n and David M. Checkley Jr Large and productive fisheries occur in regions experiencing or projected to experience ocean acidification. Anchoveta (Engraulis ringens) constitute the world’s largest single-species fishery and live in one of
An evaluation of potentiometric pH sensors in coastal monitoring applications | Ocean acidification
July 13, 2017 An evaluation of potentiometric pH sensors in coastal monitoring applications A wealth of historical coastal water pH data has been collected using potentiometric glass electrodes, but the accuracy and stability of these sensors is poorly understood. Here we compared pH measurements from five potentiometric sensors incorporated into
