Ecological Costs of Urban Expansion in a Mangrove Ecosystem: A Case Studied
On Santa Catarina Island in southern Brazil, mangrove systems are found along about 14.7% of this coast. These areas, although declared by legislation as 'Permanent Preservation Areas',...
An Economic Contribution to Marine Park Management for Hanauma Bay, Hawaii
Hawaii's most popular underwater recreation area is the Hanauma Bay Nature Park on Oahu. To protect its valuable marine resources, the waters of the bay are designated a Marine Life COnservation...
Coastal Management and Ocean Industries in East Germany, from Central Planning Ineffectiveness Towards Local and Regional Development Strategies
In so far, the preconditions for the implementation of decentralized development tools both in coastal management and in ocean industries may be quite ideal in East Germany: there is the...
Free the Elwha|
The Elwha River flows northward from the middle of Washington's Olympic Peninsula to the Strait of Juan de Fuca. As a coastal river basin, it was once home to all five species of Pacific...
Fisheries Management Integrated System for a Sustainable Development Policy
Aquatic and terrestrial ecosystems great diversity are affected by many types of environmental impacts, originated by old economic development concepts. It is necessary a integrated multidisciplinary...
Depositional Sediment on Intertidal Marshes Near Terrebonne Bay and Atchafalaya Bay, Louisiana
The net transport of inorganic sediment through tidal bayous and dispersal into adjacent marsh systems are considered important contribution to marsh accretion. Marsh habitats are dependent...
Processes Affecting Coastal Wetland Loss in the Louisiana Deltaic Plain
Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline...
Short-Term Water and Suspended-Sediment Fluctuations in a Louisiana Marsh
To determine the timing of and driving forces for sediment suspension and deposition and the effect of impoundment, three self-recording instrument packages were deployed in a section...
Meteorological Forcing on Louisiana Wetlands
The open wetland areas of southern Louisiana are vulnerable to meteorological forcing. On the basis of over one year U.S.G.S. funded measurements of atmospheric pressure, air-sea temperature...
Marsh Submergence vs. Marsh Accretion: Interpreting Accretion Deficit Data in Coastal Louisiana
The apparent imbalance between relative sea-level rise and vertical marsh accretion is frequently cited as a major factor in the problem of wetland loss in Louisiana. Rates of relative...
Natural Resource Problem Solving: an Interdisciplinary Approach in Coastal Louisiana
Ecological issues such as coastal wetland loss cannot be adequately addressed by experts in any one particular discipline. After extensive consultation with wetland users and regulators,...
The National Status and Trends Program: Development and Future Directions
NOAA's National Status and Trends Program was initiated in 1983 to provide information on environmental quality related to levels and effects of toxic contaminants in U.S. coastal and...
Status of Contamination in the Coastal United States as Revealed from NS&T Analyses of Surface Sediments
Sediment samples have been collected from more than 300 sites along the coasts of the U.S. since 1984 as part of NOAA's National Status and Trends (NS&T) Program. These samples...
Temporal Trends of Chemical Contamination at NS&T Sites
Recent temporal trends in concentrations of ten trace elements (Ag, As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn) and of five groups of organic compounds (butyltins, tDDT, tCdande, tPCB, and...
The NS&T Intensive Bioeffects Surveys: Design Strategies and Preliminary Results
Intensive bioeffects surveys are conducted in selected areas where chemical data from the National Status and Trends (NS&T) Program indicate greatest potential for contaminant-related...
Coastal Wetlands of Ghana
The Ghanaian coast is overlain with over 50 lagoons and wetlands, which among others, are important wintering sites for European birds. Types, location and size of the wetlands are inventorised....
Argentine Deltas Morphology
Only two deltas are located along the Argentine coast, both of them at Buenos Aires state. The northern one is the Parana Delta at the Rio de La Plata estuary (34.99' Lat. Sur) and the...
Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...
Production and Decomposition of
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...
Crevasses on the Lower Course of the Mississippi River
Before construction of artificial levees, crevasses were a common event along the Mississippi River. They directed sediment out of the main channel and reduced flood stage down river....
