Spider crabs were not able to fully buffer their internal pH when exposed to ocean acidification conditions for 12 days. Behavior of the crabs was not impaired by ocean acidification conditions or acute heat stress when they happened separately, but it was when both occurred at the same time. (Laboratory ...

Ocean acidification (OA) research seeks to understand how marine ecosystems and global elemental cycles will respond to changes in seawater carbonate chemistry in combination with other environmental perturbations such as warming, eutrophication, and deoxygenation. This paper discusses the effectiveness and limitations of current research approaches used to address this goal. ...

Short-lived radium isotopes on the Scotian Shelf: Unique distribution and tracers of cross-shelf CO2 and nutrient transport

This study estimated vertical and lateral diffusion coefficients for the Scotian Shelf region using a numerical 2-D approach. It also estimates cross-shelf transport of carbon and nutrients and provides a potential mechanism for CO2 outgassing on the shelf.
