Ocean acidification stress index for shellfish (OASIS): Linking Pacific oyster larval survival and exposure to variable carbonate chemistry regimes
Authors: Iria Gimenez, George G. Waldbusser, Burke Hales https://www.elementascience.org/article/10.1525/elementa.306/ Abstract Understanding larval bivalve responses to variable regimes of seawater carbonate chemistry requires realistic quantification of physiological stress. Based on a degree-day modeling approach, we developed a new metric, the ocean acidification stress index for shellfish (OASIS), for this purpose. OASIS
Version 6 of the Surface Ocean CO2 Atlas (SOCAT) now available
On behalf of more than 100 contributing scientists worldwide, we proudly announce the release of Version 6 of the Surface Ocean CO2 Atlas (SOCAT). SOCAT (www.socat.info) is a synthesis activity by international marine carbon scientists with annual public releases. SOCAT version 6 has 23.4 million quality-controlled in situ surface ocean

New study explores the role nitrogen plays in coral reef fight against ocean acidification
Crustose coralline algae build a shallow ridge (algal ridge) on a coral reef in Moorea, French Polynesia. CSUN marine biologist Robert Carpenter and a former student, Maggie Johnson, found that increasing the amount of nitrogen helps the algae fight off the negative effects of ocean acidification.
