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......
Population maintenance of the scyphozoanCyanea sp. Settled planulae and the distribution of medusae in the Niantic River, Connecticut, USA
Tập 25 Số 1 - Trang 70-75 - 2002
Scyphozoan jellyfish are seasonally conspicuous in coastal waters, but relatively little is known about the factors that control their distribution and population dynamics.Cyanea sp is a seasonally abundant medusa in the Niantic River, Connecticut, U.S. and appears to maintain a population entirely within the estuary. To better understand the factors controlling their occurrence, we examined the t......
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......

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......
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......
Capybara (Hydrochaeris hydrochaeris rodentia: Hydrochaeridae): A mammalian seagrass herbivore
Tập 27 Số 2 - Trang 197-200 - 2004
This note reports an unknown trophic interaction between a mammalian herbivore, the capybara (Hydrochaeris hydrochaeris), and the seagrassRuppia maritima (wigeongrass) and compares the feeding behavior of capybaras to other seagrass grazers. Observations were made in Spring 2002 in the Barra Grande, a small, shallow, moderately stratified, bar-built estuary at Ilha Grande, Rio de Janeiro State, so......
Gas exchange in rivers and estuaries: Choosing a gas transfer velocity

Hypersaline bottom water: Peard Bay, Alaska
Tập 2 Số 3 - Trang 189-193 - 1979
Hypersaline bottom conditions have been observed in Peard Bay, Alaska. The water appears to be renewed on an annual basis. Although it does not seem to affect permafrost degradation rates in Peard Bay, similar pools of water along the Beaufort Sea coast could greatly increase the rates of permafrost degradation. Order of magnitude estimates suggest that the hypersaline waters do not become anoxic.
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 ......
