Sediment Data from the Continental Rise (ZIMMERMAN72 shapefile)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 22, 2026 | Last Modified: 2021-11-16T00:00:00Z
Short cores were collected on the continental rise off Georges Bank. The character of the sediments and measured bottom currents show that the Western Boundary Undercurrent is a significant factor in sediment transport and deposition along the east coast continental rise. Size data for the sand and mud fractions were estimated by the compilers by subtracting the percent carbonate (composed largely of sand-sized planktonic foraminifera) from the coarse fraction. Silt and clay were not differentiated; the fine fraction is reported as mud.
