Rapid postglacial shoreline changes in the western Gulf of Maine and the Paleo-Indian environment
Robert N. Oldale
1985, American Antiquity (50) 145-150
Rapid shoreline regression and transgression along the western Gulf of Maine between 13,000 and 9000 years B.P. are inferred to have produced a nearshore marine environment low in biologic productivity. Paleo-Indians living near the coast of the Gulf were probably forced to rely on nonmarine resources landward of the late-glacial...
A drowned Holocene barrier spit off Cape Ann, Massachusetts
Robert N. Oldale
1985, Geology (13) 375-377
Seismic profiles and bathymetric contours reveal a drowned barrier spit on Jeffreys Ledge off Cape Ann, Massachusetts. Seaward-dipping internal reflectors indicate that a regressive barrier formed during the early Holocene low sea-level stillstand. Preservation of the barrier spit may have been favored by its large size (as much as 20...

Deborah R. Hutchinson, John A. Grow
1985, Geological Society of America Bulletin (96) 975-989
High-resolution, single-channel and multichannel seismic-reflection profiles in the New York Bight provide 7 crossings of a 50-km-long fault that trends north-northeast for 30 km from its southern end, then bends northeast, and may continue northward beneath Long Island. Displacement, which is consistently down to the west, decreases upsection and suggests...
Comparison of methods for measuring surface area of submersed aquatic macrophytes
Charles L. Brown, Bruce A. Manny
1985, Journal of Freshwater Ecology (3) 61-68
The surface area of submersed macrophytes is often viewed from different perspectives such as substrate for colonization by periphyton, or protective cover for fishes. Consequently, several different methods have been used to measure it. We describe a method for measuring that area with an electronic surface area meter, a device...
