Salt Measurement on the Coast of Barbados, West Indies

Abstract

Examination of ecological literature shows little evidence of the measurement of the distribution of airborne salt particles on coasts. This factor was investigated in Barbados in 1967. Quantities of salt were measured in the air, at ground surface, and within the soil at various distances from the sea. Samples were collected from 15 locations during a range of weather conditions. The results show a regular decrease in salinity with increasing distance from the sea. Quantities of salt in the soil have a direct relationship to silt and clay content. For any soil-type salt concentrations are higher on the Windward coast. There is a close relationship between changes in aerial and surface salt deposition and windspeed on the Windward coast. The average quantities of salt deposited at the ground surface range from 1/6 air salinity in exposed situations to 2/3 air salinity on the Leeward coast. Relief is an important factor in ground surface salt deposition through its effects on the lower strata of the air.
