Seasonality of materials transport through a coastal freshwater marsh: Riverine versus tidal forcing
Tập 9 Số 4 - Trang 301-308 - 1986
Transports of nitrate and suspended solids were measured six times from January
1984 until January 1985 in a small freshwater tidal bayou in south-central
Louisiana. The bayou and adjacent marshes are influenced by Atchafalaya River
discharges, tides, and coastal weather patterns. Large net ebb-directed water
transports occurred in winter, spring, and summer, coincident with high river
discharges,...
The influence of nitrogen level, form, and application method on the growth response ofSpartina alterniflora in North Carolina
Tập 2 Số 2 - Trang 106-112 - 1979
The influence of nitrogen level, form, and application method on the growth
response of short and tallSpartina alterniflora was determined in a North
Carolina salt marsh. The application of various nitrogen levels increased the
aerial standing crop of shortSpartina as much as 172%, but had no significant
effect on that of the tall form. Band application produced a significantly
greater yield respo...
Seasonal control of the Saint-Lawrence maximum turbidity zone by tidal-flat sedimentation
Tập 9 Số 2 - Trang 84-94 - 1986
The core of the turbidity maximum zone in the Saint-Lawrence Estuary is located
in the North Channel and oscillates in front of the large (3×106 m2) intertidal
flats and marshes of Cap Tourmente. It is shown that seasonal fluctuations in
the intensity and the position of this core are mainly determined by suspended
sediment exchanges between the channel and the marshes. Fine sediments, most of
the...
Salinity history of coastal marshes reconstructed from diatom remains
Tập 22 Số 4 - Trang 1078-1089 - 1999
Sediment cores were collected from three Louisiana coastal marsh ponds, dated
with radioisotopes, and analyzed for diatom remains to determine if long-term
salinity changes were evident in the sediment record. A diatom-based salinity
index formulated from a statistical comparison of available salinity data and
changing diatom assemblages demonstrated that diatom remains appear to preserve
salinity...
Infaunal community development of artificially established salt marshes in North Carolina
Tập 17 Số 2 - Trang 489-500 - 1994
In recent years, artificial establishment of Spartina alterniflora marshes has
become a common method for mitigating impacts to salt marsh systems. The
vegetative component of artificially established salt marshes has been examined
in several studies, but relatively little is known about the other aspects of
these systems. This study was undertaken to investigate the infaunal community
of artifici...
Temporal variability of remotely sensed suspended sediment and sea surface temperature patterns in Mobile Bay, Alabama
Tập 13 Số 2 - Trang 155-160 - 1990
Distribution patterns of suspended sediments and sea surface temperatures in,
Mobile Bay were derived from algorithms using digital data from the visible,
near infrared, and infrared channels of the Advanced Very High Resolution
Radiometer (AVHRR) on the NOAA-TIROS-N satellite. Closely spaced AVHRR scenes
for January 20, 24, and 29, 1982, were compared with available environmental
information take...
Effects of sediment contaminants and environmental gradients on macrobenthic community trophic structure in Gulf of Mexico estuaries
Tập 23 Số 3 - Trang 411-424 - 2000
Macrobenthic communities from estuaries throughout the northern Gulf of Mexico
were studied to assess the influence of sediment contaminants and natural
environmental factors on macrobenthic community trophic structure. Community
trophic data were also used to evaluate whether results from laboratory sediment
toxicity tests were effective indicators of site-specific differences in benthic
trophic ...
Marine and estuarine shallow water science and management: The interrelationship among habitats and their management

Transient hydrodynamic and salinity simulations in the Chesapeake Bay network
Tập 6 Số 4 - Trang 356-363 - 1983
A transient network model is applied to the Chesapeake Bay and its tributary
estuaries. Calibration of the model is based on only three external parameters:
a friction factor that is spatially described, and two global constants required
to calibrate a dynamic dispersion relationship that depends on both the local
salinity gradient and hydraulic conditions. The transient hydrodynamics and the
tran...
