ItemA biological evaluation of the Delaware River estuary(University of Delaware Marine Laboratories, 1959-09) Shuster, Carl N.This report deals with the biological productivity of a unit of Nature, the Delaware River estuary. In many respects this estuary and its productivity is similar to that of the several other estuaries along the Atlantic coast of North America, but each, like a person, has its own individual characteristics. This productivity and related biological, chemical, geological, and physical characteristics of the Delaware River estuary are not known fully, yet they are being studied and the descriptions and knowledge obtained each year can be useful to those persons concerned with the best use of our coastal areas. ItemFishes and ecological conditions in the shore zone of the Delaware River estuary: with notes on other species collected in deeper water(Newark : Dept. of Biological Sciences, University of Delaware, 1962-04) De Sylva, Donald P.; Shuster, Carl N.; Kalber, Frederick A.Information was collected during the period August 1958-February 1960, concerning the distribution of fishes in the shore zone in relation to the various environments found at sixteen sites within the Delaware River estuary and adjacent areas of the Atlantic coast. Over 54,000 fishes comprising 66 species were collected in the shore zone. Data were occasionally collected concerning the presence of these 66 species in the deeper waters of the estuary as well as the occurrence of 72 species not caught in the beach zone area. Measurements of salinity, temperature, oxygen saturation, and turbidity of the water were taken at the time of fish collection. Observations of tide condition, plant associations, bottom type and associated animals were also made at the collection sites. ItemTide marsh ecology and wildlife(Newark, Del. : Marine Laboratories, Dept. of Biological Sciences, 1970) Daiber, Franklin C.; Gallagher, John L.; Sullivan, Michael J.Research on the ecology of Delaware's tidal salt marshes has focused on nutrient and energy budgets of such areas. The flux of various forms of phosphorus and nitrogen in the water entering and leaving the marshes has been investigated, the role of bacteria in nutrient cycling has been studied and the production of the angiosperms has been estimated. The role of algae in this system has not been previously investigated. In this study some aspects of the algae's role in the nutrient and energy cycles and the ecological factors that influence this role have been measured. ItemTide marsh ecology and wildlife: salt marsh plants and future coastal salt marshes in relation to animals(Newark, Del. : College of Marine Studies and and Department of Biological Studies, 1972) Daiber, Franklin C. ItemEnergy utilization in the marsh crab, Sesarma reticulatum, and its relation to cyclic patterns(Newark, Del. : College of Marine Studies and Department of Biological Sciences, 1972) Daiber, Franklin C.; Jackewicz, Joan R.A study was undertaken to determine the energy utilized by Sesarma in feeding upon Spartina over lunar-monthly periods. Amounts of Spartina ingested and assimilated, in terms of grams dry weight, were found for three groups of crabs. These studies indicate a possible relationship between the quantity (i.e. grams dry weight) and/or quanity (i.e. associated with maturity) of Spartina available to the crabs and the amounts ingested and assimilated. These data, in addition to data from respiration measurements, were combined with information from the literature to construct energy budgets, in terms of caloric values, for the three groups. ItemTide marsh ecology and wildlife(Newark, Del. : College of Marine Studies and Department of Biological Sciences, 1972) Daiber, Franklin C.; Sullivan, Michael J.The chief objective of the research is to test the hypothesis that light intensity and nutrients are significant factors in the structure of the edaphic diatom assemblage and in the abundance of edaphic soil algae. ItemHistory, Land Ownership, and Laws, Including a Survey of Maps Prior to 1840(Newark, College of Marine Studies, University of Delaware., 1973) Natural and Historic Resource Associates; Polis, Dennis F.Volume 2 addresses itself to three areas of marine affairs vital for an understanding of the bay system. In the first part, the history of the region is discussed, with special emphasis on the role of waterborne transportation in the formation of land-use patterns. The second part delves into land ownership and use in the coastal margin around the bay. The third part reviews the state and federal laws available for the management of the bay. ItemThe biology of the oyster community and its associated fauna in Delaware Bay(Newark, College of Marine Studies, University of Delaware., 1973) Maurer, Don; Watling, LesThe purpose of this account is to describe the composition of the associated invertebrate fauna of Delaware Bay oyster beds, and to determine the effect of salinity, substrate, and season on this fauna. The dependence of the number of species in a bed community on maximum salinity is discussed, together with its temporal variability. The associated oyster fauna of Delaware Bay is very similar to estuaries throughout the world and thus this report may have more than local interest. ItemGuide to the macroscopic estuarine and marine invertebrates of the Delaware Bay region(Newark, College of Marine Studies, University of Delaware., 1973) Watling, Les; Maurer, DonThis volume represents the first major compilation of invertebrate species for the Delaware Bay region. Included in the volume are: a key to the major kinds of invertebrates in this region; taxonomic listings of over 300 species collected by the authors or referred to in other published papers; keys to these species; lists of species which, because of their known geographic distribution, may be expected to occur in this region; and a comprehensive bibliography of papers dealing with the species listed. ItemPhysical oceanography and Chemical oceanography(Newark, College of Marine Studies, University of Delaware., 1973) Szekielda., Karl-Heinz; Polis, Dennis F.; Kupferman, Stuart L.The physical and chemical environment of the bay system is dealt with in this two-part report. Part one provides fundamental information on the morphology, tides, currents, salinity and temperature of Delaware Bay. The spatial and temporal variability of these factors are discussed and most of the available data is summarized. Part two treats the chemistry of the Delaware Estuary. Averaged over a two-year period, data on chloride, chromium, iron, chlorophyll, phenols, oxygen, phosphate, and nitrite are presented and discussed in terms of hydrographic conditions and biochemical reactions. ItemEconomic and Social Aspects of Delaware's Coastal Zone(Newark, College of Marine Studies, University of Delaware., 1973) Goodman, Joel MyronIn this volume the economic and social aspects of Delaware's coastal zone are considered from several different viewpoints. The first section develops a management and regulatory perspective. This is followed by two sections which deal with historical and contemporary perspectives, placing emphasis upon general industrial and social development, and the evolution of transportation, recreation, and commercial fisheries. The closing section of the volume considers a planning perspective and looks briefly into development issues involved in the future economic and social development of the Coastal Zone. ItemPictorial guide to fish larvae of Delaware Bay, with information and bibliographies useful for the study of fish larvae(Newark, College of Marine Studies, University of Delaware., 1973) Scotton, Lewis N.; Smith, Robert E.; Smith, Nancy S.; Price, Kent S.; de Sylva, Donald P.This volume i.s divided into two parts: The pictorial guide composing the first part includes two large charts which are, in effect, an illustrated table of contents, designed to permit quick identification of larval specimens. Following this, the larval stages of 56 species of marine fishes collected in the Delaware Bay are illustrated serially (from younger to older). The notes for each species discuss adult characteristics, egg and larval development, spawning, distribution and pertinent references. The second part provides information on several aspects of the study of fish larvae, i.e., laboratory identification; preservation and sorting; laboratory rearing and field sampling methods. A bibliography is included for each section: and there is also a bibliography of selected general references on fish eggs and larvae. ItemComprehensive bibliography on Delaware Bay(Newark, College of Marine Studies, University of Delaware., 1973) Plunguian, Mark; Fothergill, Robert E.; Longenbach, Anne H.; Cook, EvelynThis series is completed by a comprehensive indexed bibliography on all aspects of the Delaware Estuarine system. ItemBaseline study plans(Newark, College of Marine Studies, University of Delaware., 1973) Polis, Dennis F.The outline plan of a comprehensive and coordinated five-year study of the scientific and engineering aspects of Delaware Bay is presented in this volume. Specifications are provided for many subprojects, while others are simply outlined. The thrust of the study is the production of a crude overall predictive model for the physical and biological aspects of the bay system. ItemTrace Metal Geochemistry of Estuarine Sediments(Newark, College of Marine Studies, University of Delaware., 1973) Strom, Richard N.; Bopp III, Frederick; Biggs, Robert B.; Lepple, Frederick K.; Polis, Dennis F.This volume consists of three sections. The first part of this volume relates to the general distribution and composition of fine-grained sediments in the bay. In the second section, the relationship between the character of the fine-grained sediments and trace metal levels is developed. The third attempts to evaluate domestic sewage discharge as a source of metals in the estuarine environment. ItemInventory and Evaluation of Information on Delaware Bay(Newark, College of Marine Studies, University of Delaware., 1973) University of Delaware, College of Marine Studies.; Polis, Dennis F.The volume which the reader has in his hands is designed to provide a starting point for those wishing to become acquainted with the bay. It reviews briefly the present research on the bay, the general availability and quality of data (including maps and aerial photography); technical, research, and advisory groups dealing with the bay; and finally future plans and proposals for the bay region. ItemEcological studies on benthic and planktonic assemblages in lower Delaware Bay(College of Marine Studies University of Delaware, Lewes, Delaware, 1976) Watling, Les; Maurer, DonThis study was undertaken to obtain baseline ecological data in Delaware Bay. During the summers of 1972 and 1973 the first bay-wide quantitative survey of benthic organisms was conducted. The survey consisted of 207 samples distributed over 26 transects from the bay mouth to Woodland Beach, Delaware. Based on the results of the bay-wide survey reported herein, it was decided to conduct an intensive study in the oil lightering area in lower Delaware Bay (1974-1975). The intensive study included quantitative monthly investigations of phytoplankton and zooplankton together with quarterly investigations of the benthos. Two 12hour plankton studies were also conducted. In addition to the quantitative benthic studies, there were extensive samples with dredge hauls. Data from dredge hauls and grabs were compared to determine whether a useful method of community analysis could be developed based on dredge data alone. It was concluded, that such a method was feasible but that it required additional refinement. Some of the survey data were never reported for Delaware Bay prior to this study. ItemPhylum mollusca : a guide to the mollusca of the Delaware Bay region(Newark, College of Marine Studies, University of Delaware., 1976) Leathem, Wayne; Maurer, Donald ItemTidal marsh wildlife and their habitats(Newark, Del.: College of Marine Studies and School of Life and Health Sciences, 1977) Daiber, Franklin C.The present paper will review various parameters and their interactions that influence marsh animal distributions which in turn influence facets of life histories such as breeding, feeding and behavior. No attempt will be made to be all inclusive, whole groups of animals will not be covered such as the Foraminifera.
