NOAA National Data Buoy Center, Tropical Atmosphere Ocean (TAO) Program, Shannon McArthur, TAO Program Manager

“What impact would a 30% reduction in ship time on the Ka’imimoana have on the tropical Pacific ocean observing system, and what approach should be taken to continue monitoring and delivery of observing system data necessary for essential analysis and forecasting?”
