The economic effects of harmful algal blooms in the United States: Estimates, assessment issues, and information needs
Tập 25 Số 4 - Trang 819-837 - 2002
During the last several decades, harmful algal bloom (HAB) events have been
observed in more locations than ever before throughout the United States.
Scientists have identified a larger number of algal species involved in HABs,
more toxins have been uncovered, and more fisheries resources have been
affected. Whether this apparent increase in HAB events is a real phenomenon or
is the result of incr...
A comparison of residence time calculations using simple compartment models of the Altamaha River estuary, Georgia
Tập 25 Số 6 - Trang 1304-1317 - 2002
The residence and flushing times of an estuary are two different concepts that
are often confused. Flushing time is the time required for the freshwater inflow
to equal the amount of freshwater originally present in the estuary. It is
specific to freshwater (or materials dissolved in it) and represents the transit
time through the entire system (e.g., from head of tide to the mouth). Residence
tim...
Gas exchange in rivers and estuaries: Choosing a gas transfer velocity

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,...
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...
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...
Morphometric relationships of penaeid shrimps in a coastal lagoon: Spatio-temporal variability and management implications
Tập 25 Số 2 - Trang 282-287 - 2002
Spatio-temporal variability in the length-weight relationship of four sympatric
shrimp species (Farfantepeneus aztecus, F. brasiliensis, F. duorarum, andF.
notialis) was evaluated in the Celestun lagoon, Mexico. Monthly samples were
taken throughout 2 yr in three hydrological zones (seaward, middle, and inner)
and climatic seasons (Nortes, Dry, and Rainy). Significant intraspecific and
interspecif...

Accretion and canal impacts in a rapidly subsiding wetland. III. A new soil horizon marker method for measuring recent accretion
Tập 12 Số 4 - Trang 269-283 - 1989
A new methodology used on a large scale is reported by which short-term (≤1 yr)
marsh accretion rates were measured in saltwater and brackish marshes and
compared to first-time measurements made in freshwater marshes. The stable
rare-earth elements (REE) dysprosium and samarium were used for soil horizon
markers that were collected by a cryogenic field coring method and detected by
instrumental ne...
Mixing behavior of dissolved organic carbon and its potential biological significance in the Pawcatuck River Estuary
Tập 17 Số 3 - Trang 521-536 - 1994
The distributions of dissolved organic carbon (DOC), phytoplankton biomass (as
measured by in vivo fluorescence), total nitrogen and phosphorus, and light
extinction were observed on 10 cruises during 1989 and 1990 in the Pawcatuck
River estuary located in southern Rhode Island. In the lower estuary, the
distance of peak phytoplankton biomass from the head of the estuary was
positively correlated ...
