Predicting the Long-Term Fate of Sediments and Contaminants in Massachusetts Bay

USGS Fact Sheet 172-97
Figure 6. Paths of a few of the drifters released in May 1990 illustrating the variability of the surface currents in Massachusetts Bay. Drifters (surface floats attached to an underwater drogue) were released (initial locations at the red dots) and tracked via satellite until they either left the bay or grounded ashore. For drifters set out during various times of the year as part of a field experiment carried out in 1990-91, traveltimes from western Massachusetts Bay to Cape Cod Bay ranged from 4 to 7 days and from western Massachusetts Bay to Race Point ranged from 7 to 50 days. (Geyer and others, 1992.)
