Every year huge quantities of soil dust are carried by winds from Africa, across the Atlantic, and to the Caribbean. No other ocean region is so extensively and persistently impacted by such high concentrations of dust, a region that extends over 7000 km from the coast of Africa to the Caribbean and to the bounding continental shores of the Americas. In effect, the Caribbean Basin can be thought of as the receptor site of the Saharan dust source, a source that accounts for over half of global dust emissions. It is generally recognized that on a global scale mineral dust can affect many aspects of climate, marine biogeochemical processes, soil fertility, air quality, and human health. However, it is difficult to assess the impact on the Caribbean Basin because of the dearth of studies in this region. A better understanding is needed of the factors that affect the transport of dust, the physical and chemical properties of the transported materials, and how these might change during transport. Of particular interest is how climate change might affect dust transport in the future. Presented here is a brief overview of research relevant to the region and issues in dust-related research that need to be addressed.
