This collaboration joins bioacoustics experts, carbonate chemists and molecular biologists, to determine how carbon dioxide (CO2) affects the physiology and distribution of pteropods in the NW Atlantic and NE Pacific Oceans. This project relies on the natural differences between the hydrography of the NW Atlantic and NE Pacific Oceans to provide a natural experiment investigating whether masses of hypercapnic (high CO2) water act as barriers to thecosome pteropod diel migration. My particular focus is assessing whether various Pacific and Atlantic species and sub-species of pteropods have different metabolic responses to CO2 and O2 separately, and additively (Maas and Lawson, in prep). |
