AB: Global transport of dust has been acknowledged as a significant factor in atmospheric radiative balance, atmospheric oxidizing capacity, the deposition of limiting nutrients into the upper ocean, transport of fungi and microorganisms, and in the indirect aerosol effect via cloud modification. In early spring 2004, a group of scientists from NOAA, Howard University, the University of Puerto Rico - Mayagez, and several international partners will take part in a research cruise aboard the Ron Brown to study the impacts and microphysical evolution of Saharan dust during its trans-Atlantic transport on the local atmosphere and marine boundary layer. The fundamental purpose of this research cruise is to provide a set of critical measurements to characterize the impacts of Saharan dust aerosol transport across the Atlantic Ocean. The preliminary science plan and goals of the cruise will be presented and discussed as well as some background measurements taken over the past two years in the Caribbean and Canary Islands.
