The Texture of Surficial Sediments in Eastern Long Island Sound Near Falkner Island, Connecticut by Poppe, L.J.1, Taylor, B.B.1
U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY The texture of surficial sediments in eastern Long Island Sound near Falkner Island, Connecticut by Poppe, L.J. 1 , Taylor, B.B. 1 , Blackwood, Dann1 , Lewis, R.S. 2 , and DiGiacomo-Cohen, M.L. 2 Open-File Report 97-251 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards (or with the North American Stratigraphic Code).

The relative grain-size frequency distributions and related statistics are reported herein. Descriptions of the benthic character from video tapes and still camera photographs of the bottom at these stations, and 12 others, are also presented. Gravelly sediments and bouldery outcrops, which reflect environments of erosion or nondeposition, occur adjacent to Falkner and Goose Islands, over shoals extending northward and southward from the islands, and on isolated bathymetric highs in the northern part of the study area. Sands surround these gravelly deposits and dominate the remainder of the study area. Silty sands, which are the finest-grained sediments in the study area, occur in lower- energy, more-protected environments, such as in small patches just west and southeast of Goose Island.
