Impact of the Eastern oyster Crassostrea virginica on microbial community structure in a salt marsh estuary
(Inter-Research, 2002-05-16)In the tidal creeks of North Inlet, a high salinity salt marsh estuary near Georgetown, South Carolina, USA, the Eastern oyster Crassostrea virginica is an abundant component of the benthic macrofauna that exerts controls ... -
Response of bacteria to simulated upwelling phytoplankton blooms
(Inter-Research, 2004-05-19)Until recently, studies of the fate of primary production in coastal upwelling systems have focused mainly on export through sinking of particulate organic matter (POM). In week-long deck incubations conducted during the ... -
Light-induced growth of phytoplankton collected during the winter from the benthic boundary layer off Oregon, USA
(Inter-Research, 2004-10-14)Despite the importance of the spring phytoplankton bloom off Oregon as a food source for zooplankton, little is known about the sources of phytoplankton seed stock for the bloom or its timing. Experiments were conducted ... -
Variability in phytoplankton pigment biomass and taxonomic composition over tidal cycles in a salt marsh estuary
(Inter-Research, 2006-08-29)Tidal flow causes high temporal variability in environmental properties that impact ecosystem dynamics. Microbes such as phytoplankton are especially susceptible to tidal advection and mixing, and understanding their role ... -
MERIS Retrieval of Water Quality Components in the Turbid Albemarle-Pamlico Sound Estuary, USA
(MDPI, 2011-04-01)Two remote-sensing optical algorithms for the retrieval of the water quality components (WQCs) in the Albemarle-Pamlico Estuarine System (APES) were developed and validated for chlorophyll a (Chl). Both algorithms were ... -
Environmental controls upon picophytoplankton growth and biomass in a eutrophic estuary
(Inter-Research, 2011-03-31)We assessed the role of top-down versus bottom-up factors in regulating picophytoplankton (PicoP) growth and overall phytoplankton size structure in a eutrophic estuary. PicoP biomass reached an annual maximum in summer/fall ... -
Effects of Nitrogen Availability and Form on Phytoplankton Growth in a Eutrophied Estuary (Neuse River Estuary, NC, USA)
(PLoS ONE, 2016-08-09)Nitrogen availability and form are important controls on estuarine phytoplankton growth. This study experimentally determined the influence of urea and nitrate additions on phytoplankton growth throughout the growing season ... -
Effect of hydrological variability on the biogeochemistry of estuaries across a regional climatic gradient
(Association for the Sciences of Limnology and Oceanography, 2018-08-15)Given projected changes in river flow to coastal regions worldwide due to climate change and increasing human freshwater demands, it is necessary to determine the role hydrology plays in regulating the biogeochemistry of ... -
Saharan dust deposition initiates successional patterns among marine microbes in the Western Atlantic
(Wiley Periodicals, Inc., 2019-08-02)Deposition of aerosolized desert dust can affect marine microbial community structure and function through pulsed addition of limiting micro- and macronutrients. However, few studies have captured responses to dust deposition ... -
Water quality trends in Texas estuaries
(Elsevier Ltd., 2020-01-15)Coastal watersheds in Texas have experienced significant human population growth over the past several decades, yet there have been no comprehensive assessments of water quality trends in Texas estuaries. Here, analysis ... -
Photomineralization of organic carbon in a eutrophic, semiarid estuary
(Wiley Periodicals, Inc., 2020-01-28)The effect of photomineralization on the carbon cycle in a eutrophic, semiarid estuary (Baffin Bay, Texas) was investigated using closed-system incubations. Photochemical production rate of dissolved inorganic carbon ranged ... -
Disparate Responses of Carbonate System in Two Adjacent Subtropical Estuaries to the Influence of Hurricane Harvey – A Case Study
(Frontiers in Marine Science, 2020-01-31)Two adjacent estuaries in the northwestern Gulf of Mexico (GOM) (Mission–Aransas or MAE and Guadalupe–San Antonio or GE), despite their close proximity and similar extents of freshening caused by Hurricane Harvey, exhibited ... -
Timescales and Magnitude of Water Quality Change in Three Texas Estuaries Induced by Passage of Hurricane Harvey
(Estuaries and Coasts, 2020-10-14)Tropical cyclones represent a substantial disturbance to water quality in coastal ecosystems via storm surge, winds, and flooding. However, evidence to date suggests that the impacts of tropical cyclones on water quality ... -
An assessment of trends in the frequency and duration of Karenia brevis red tide blooms on the South Texas coast (western Gulf of Mexico)
(PlosOne, 2020-09-18)Limited data coverage on harmful algal blooms (HABs) in some regions makes assessment of long-term trends difficult, and also impedes understanding of bloom ecology. Here, observations reported in a local newspaper were ...
