Abstract

Analysis of 69 shuttle and satellite images of the northern Bahamas taken from 1965 to 1993 allowed us to calculate the regional and temporal distribution and longevity of 888 whitings on the Great Bahama Bank. At any time, whitings cover between 35 and 200 km2 in the area centered at lat 25°N and 78°50'W. The highest occurrences of whitings are in April and October, suggesting a seasonal component. Using a measured average of 10.6 mg/L suspended sediment in typical whitings, we calculated that 1.35 × 106 metric tons of lime mud are suspended every year. If the suspended carbonate is precipitated in the water column, these phenomena account for 280% of all of the Holocene accumulated bank top mud and more than 40% of the total bank top mud and periplatform mud that have accumulated on the west side of Great Bahama Bank.
