Cruise Info
| Cruise ID | NH0912 |
| Vessel | R/V NEW HORIZON |
| Abstract | On this cruise, we will test a system to continuously measure dissolved gases in seawater. We will be pumping seawater into an equilibrator, which allows dissolved gases to come to equilibrium with sweep gas from a tank. The equilibrated air will then be sent into a mass spectrometer on board the ship for continuous measurement. The mass spectrometer was tested on the R/V New Horizon in June 2008, and was found to have high precision even at sea. On this cruise we will take continuous measurements of O2/N2 and Ar/N2 ratios, along with isotopes of oxygen and nitrogen. These measurements can give information about primary production in the ocean. It is of interest to test the method in a transect between near-shore and open ocean conditions. |
