"This report describes colony distribution, species abundance, historical trends, nesting chronology, and census techniques for 28 species of seabirds and wading birds from Cape Elizabeth, Maine to the Virginia-North Carolina border" (p. iv).

From Introduction: "This paper describes some results of the first eight years of a fifteen year program in which a variety of coating and catholic protection systems are evaluated on their ability to protect steel piles in offshore conditions at Dam Neck, Virginia. It includes a description of the methods used in the evaluation and the results found on these systems."

Abstract: "Results of an investigation conducted to determine the engineering feasibility of using dredged material to expand an existing marshland area are presented. Dredged material obtained from maintenance dredging operations was found suitable for use as marsh substrate and site conditions were found adequate for construction of a containment facility. Factors evaluated in the study include site-specific feasibility of marsh expansion using dredged material, sizing of the demonstration area to meet water-quality and storage needs, preliminary design of the containment facility, procedures for the placement of dredged material, and identification of alternative construction methods, materials, and costs. Overall feasibility of marsh expansion was demonstrated and additional investigations were recommended for the project."

This summary report is part of a series documenting the field site investigations conducted by the Habitat Development Project initiated to study for more definitive information on the environmental impact of dredging and dredged material disposal operations. This report documents tasks such as: (a) Effects of Marsh and Terrestrial Disposal, (b) Marsh Development, (c) Terrestrial Habitat Development, (d) Aquatic Habitat Development, and (e) Island Habitat Development.

This report follows the Windmill Point marsh habitat development project. The marsh was constructed in the James River between November 1974 and February 1975, then studied for benthic invertebrates, fish, wildlife, plants and soil characteristics from the summer of 1976 to fall of 1977.

From preface: "This report contains the results of investigations of the chemical and sedimentological characteristics of the James River Artificial Habitat Development Site and a reference marsh near Windmill Point, Virginia. Studies were conducted in the channel before dredging and during site construction as well as at specific time intervals after marsh development."
