I am writing from the Onnuri research vessel near Geoje South Korea. Over the last two days, scientists from NASA, NOAA, NRL, US universities, and the Korea Institute of Ocean Science and Technology (KIOST), have been intensely preparing for the KORUS oceanographic field campaign, designed to capture coastal ocean dynamics in the East Sea and Yellow Sea. Measurements will be used for risk-reduction purposes to facilitate the design of future ocean color sensors that will be continuously observing the US coastal waters from a geostationary orbit.
The research crew has been setting up and troubleshooting instruments, which has at times been challenging but seldom dull. Our group will be operating a shipboard Pandora spectrometer, for total column measurements of trace gases and aerosol properties, and in-situ sensors for measurements of surface concentrations of atmospheric pollutants. We will be using these measurements to understand changes in the atmospheric composition at the land-ocean interface, inform model parameterizations, and access impacts of air pollution on satellite ocean color retrievals.
As I currently write, we are minutes away from setting sails. All instruments onboard R/V Onnuri and the smaller Jangmok boat are operating well. We will be traversing the entire South Korean coastline taking air and water quality measurements over the next 18 days, trying to understand variability in atmospheric dynamics and ocean processes. Off we go..
