    Hydrocarbon incorporation into the salt marsh ecosystem from the West Falmouth oil spill
    (Woods Hole Oceanographic Institution, 1971-11) Burns, Kathryn A. ; Teal, John M.
    The oil barge "Florida" ran aground just off Little Island, West Falmouth, Massachusetts on September 16, 1969. About 175,000 gallons of Number Two fuel oil leaked into Buzzards Bay and the adjacent Wild Harbor Marsh. This report presents the results of analyses done on marsh muds and organisms collected nearly a year after the spill. We studied the incorporation of polluting hydrocarbons into, and their movement through the marsh ecosystem. Analyses of surface muds agreed well with observations on plant growth. The dead areas were the most heavily polluted. A deep mud core in the dead area showed oil has penetrated to at least 70 cm. Virtually all the marsh organisms living in the contaminated area were affected by the oil at least to the extent that they accumulated oil hydrocarbons in their tissues. Our data suggest that two processes may occur as the oil passes through the marsh ecosystem. There may be a progressive loss in the straight chain hydrocarbons in relation to branched chain, cyclic and aromatic hydrocarbons. There also appears to be a selection for the higher boiling fractions of the contaminants higher up the food chain.

    Technical progress report : advanced marine technology 1 February 1972 - 31 July 1972
    (Woods Hole Oceanographic Institution, 1973-02-28) Aldrich, Thomas C. ; Maxwell, Arthur Eugene ; Ballard, Robert D. ; Bowin, Carl O. ; Luyendyk, Bruce P. ; McCamis, Marvin J. ; Phillips, Joseph D. ; Porter, David L. ; Vine, Allyn C. ; Teal, John M. ; Marquet, William M. ; Winget, Clifford L. ; von Herzen, Richard P. ; Williams, David L.
    The two extremes of the program in this six month period were the Submerged Navigation System which was demonstrated to be a successful field system, and the near Bottom Continuous Gravity System, which was priced out of the market by the acceleration characteristics of ALVIN. In all the other subjects discussed in summary immediately below and in more detail further on, satisfactory progress was made. Again aircraft scheduling has held up further work on the Air Sea Systems project, but there is definite hope for some aircraft tiem in the fall. The Development of Equipment for Deep Sea Biological Research has been terminiated as of the beginning of this report.

    Managing coastal resources in the 21st century
    (Ecological Society of America, 2007-01) Weinstein, Michael P. ; Baird, Ronald C. ; Conover, David O. ; Gross, Matthias ; Keulartz, Jozef ; Loomis, David K. ; Naveh, Zev ; Peterson, Susan B. ; Reed, Denise J. ; Roe, Emery ; Swanson, R.

    Coastal ecosystems are increasingly dominated by humans. Consequently, the human dimensions of sustainability science have become an integral part of emerging coastal governance and management practices. But if we are to avoid the harsh lessons of land management, coastal decision makers must recognize that humans are one of the more coastally dependent species in the biosphere. Management responses must therefore confront both the temporal urgency and the very real compromises and sacrifices that will be necessary to achieve a sustainable coastal ecosystem, one that is economically feasible, socially just, and ecologically sound.

    The interaction between science and policy in the control of Phragmites in oligohaline marshes of Delaware Bay
    ( 2005) Teal, John M. ; Peterson, Susan B.
    Public Service Enterprise Group of New Jersey restored Delaware Bay marshes to enhance fish production as part of a mitigation negotiated in a company’s NJPDES permit. Restoration meant control of an introduced type of the common reed, Phragmites, that had displaced Spartina alterniflora and S. patens. Phragmites dominance altered the function and structure of these brackish marshes and reduced habitat value by raising and flattening marsh surface and covering smaller tidal creeks. A common control technique is to use an herbicide – Glyphosate, but public concern about herbicide use resulted in an agreement between PSEG and NJ regulators to test other methods for reed control and limit the amount of herbicide used. Experiments with methods of Phragmites control indicate that herbicide application over three or more growing seasons, concentrating in an area until control was complete, is the most effective control method.

    Ceratoscopelus maderensis : pecular sound-scattering layer identified with this myctophid fish
    (Woods Hole Oceanographic Institution, 1968-10) Backus, Richard H. ; Craddock, James E. ; Haedrich, Richard L. ; Shores, D. L. ; Teal, John M. ; Wing, A. S. ; Mead, Giles W. ; Clarke, William D.
    A sound- scattering layer, composed of discrete hyperbolic echo-sequences and apparently restricted to the Slope Water region of the western North Atlantic, has been identified from the Deep Submergence Research Vehicle ALVIN with schools of the myctophid fish Ceratoscopelus maderensis. By diving into the layer and using ALVIN's echo-ranging sonar, we approached and visually identified the sound scatterers. The number of echo sequences observed with the surface echo-sounder (1 /23. 76 x 105 cubic meters of water) checked roughly with the number of sonar targets observed from the submarine (1/7. 45 x 105 cubic meters) . The fish schools appeared to be 5 to 10 meters thick, 10 to 100 meters in diameter, and on centers 100 to 200 meters apart. Density within schools was estimated at 10 to 15 fish per cubic meter.

    The coastal impact of ground water discharge : an assesment of anthropogenic nitrogen loading in Town Cove, Orleans, Massachusetts
    (Woods Hole Oceanographic Institution, 1983-11-14) Teal, John M.
    The shores of Town Cove have been settled for three centuries. As for most of Cape Cod, small, sparsely populated farming and fishing villages of the eighteenth century have given way to a substantial population of permanent residents today, with influxes of summer vacation residents and visitors that can increase the population several fold. Increasing numbers of our senior citizens retire to life-long vacation homes here or build new ones. Most people are attracted to the area because of its natural resources---the clean seaside environment, low wooded hills and the sheltered embayments, such as Town Cove, with clean shellfish, safe recreation and peaceful vistas. Along with growth have come many of the problems of increased population pressure, such as disposal of wastes. Although this problem has several aspects, the one we are addressing has to do .with sewage, or more specifically, with the nitrogen compounds associated with sewage that enter the groundwater and find their way to lakes, ponds, swamps and to the shores of Town Cove. This report contains our findings and assessment of the impact and potential impact of nitrogen from human sources on the Town Cove ecosystem, as well as advice to the Town on the potential impact of diverting sewage nitrogen destined for Town Cove to a nearby saltmarsh. The decision on whether or not to spend substantial amounts of money to install sewers or a septage treatment plant depends on many kinds of technical, regulatory and economic information and projections into the future. In the end, it also depends significantly on individual perceptions of how things should be done and what is valuable. Our study is intended to fill an existing gap by providing expert technical information on how Town Cove works and what nitrogen has to do with it; we cannot provide the other information and are not able to make the Town's decision on whether to install sewers.
