Science objectives
The project focuses on improving our understanding of turbulent air-sea gas exchange processes in high wind conditions. The eventual outcome of the experimental effort is an analysis leading to improvement in gas exchange parameterizations (models).Science Activities
Measurements of several air-side gas species and atmospheric turbulence will be conducted from the jackstaff (or similar mast) of the ship. The hardware for this effort includes a sonic anemometer, a suite of meteorological instruments, several sample inlet lines (tubes) leading back to vans containing the gas instrumentation and pumps.Three 20' vans are planned to house the gas measurement systems. Two of the measurement systems utilized sealed radioactive sources (Po-210 and Ni-63) which have been deployed previously on NOAA and/or UNOLS vessels.
In addition, we have two small buoys (4m and 11m, each about 1.5m in diameter) to be deployed and retrieved on about a 24 hour cycle from the back deck of the ship. These buoys will make measurements of water-side characteristics (bubbles, waves, water-side turbulence), and the data are logged on the buoy which also has GPS/Iridium link for location determination.
A WAMOS wave-measurement system that utilizes the ship's navigational radar signal will be deployed.
The ship will be positioned into the wind, with potential manoevers required to place the ship into a strong wind field or area of high gas flux. Other manoevers will be required to place and retrieve the buoys.
