Sulfate enrichment in estuaries of the northwestern Gulf of Mexico: The potential effect of sulfide oxidation on carbonate chemistry under a changing climate
(Limnology and Oceanography Letters, 2023-05-30)Water quality parameters from 2000 to 2020 were used to identify the spatial and temporal sulfate variations in estuaries of the northwestern Gulf of Mexico. Sulfate enrichment relative to conservative mixing was found to ... -
Cervinia langi n. sp. and Pseudocervinia magna (Copepoda: Harpacticoida) from the Beaufort Sea (Alaska, U.S.A.)
(Transactions of the American Microscopy Society, 1979)Two species of the family Cerviniidae have been collected from the Beaufort Sea off the coast of Alaska. Pseudocervinia magna (Smirnov, 1946) and Cervinia langi n. sp. were found in association. Lang (1936, 1948) described ... -
Two new bathyal species of Pseudotachidius (Copepoda: Harpacticoida) from the Beaufort Sea (Alaska, U.S.A.)
(Journal of Natural History, 1980)During the summer of 1977, the Oregon State University Benthic Group participated in a USCGC GLACIER cruise off the northeastern coast of Alaska, U.S.A. Two new species of Harpacticoida (Copepoda) were found from several ... -
A New Species And A New Genus Of Cerviniidae (Copepoda: Harpacticoida) From The Beaufort Sea, With A Revision Of The Family
(Proceedings of the Biological Society of Washington, 1980)Cercinia unisetosa n. sp. from the bathyal zone of the Beaufort Sea (Arctic Ocean) is unique in the Cervinia in that is possesses a reduced fifth leg, moderate length caudal rami, and only one seta on the bases of the ... -
Decomposition of Spartina alterniflora in different seasons and habitats of a Northern Massachusetts salt marsh, and a comparison with other Atlantic regions
(Estuaries, 1980-03)Packets of freshly harvested liveSpartina alterniflora were placed on the marsh surface, in a tidal ditch, in a pool contacting sides and bottom, and in the center-bottom of the same pool in September 1972. Rates of loss ... -
Production of dominant emergent vegetation and of pool algae on a northern Massachusetts salt marsh
(Bulletin of the Torrey Botanical Club, 1981)Cover frequency for the emergent vegetation of three representative sections of a salt marsh is presented. Annual production values are calculated using the ash-free dry weights of a series of harvests of standing live and ... -
Morphological adaptation in the deep-sea benthic harpacticoid copepod family Cerviniidae
(Crustaceana, 1982)Por (1964) suggested that deep-sea harpacticoids were adapted to an "epipelic way of life", by means of a "gradual elongation of limbs". To test this hypothesis I examined four closely related Arctic species to determine ... -
The relationship between abundances of meiofauna and their suspected microbial food (diatoms and bacteria)
(Estuarine Coastal and Shelf Science, 2004-11-19)Samples were taken bi-weekly for one year at a sand site and a mud site in the North Inlet Estuary, Georgetown, South Carolina, for meiofauna, their suspected microbial food (bacteria and diatoms), and associated physical ... -
Competition for dissolved glucose between meiobenthos and sediment microbes
(Journal of Experimental Marine Biology and Ecology, 2003-03-31)Meiobenthos, small invertebrates inhabiting the surface layers of marine sediments, can absorb dissolved organic matter (DOM). Experiments were performed to test if meiobenthos can compete with sediment microbes for uptake ... -
Meiofauna and chlorophyll associated with Beggiatoa mats of a natural submarine petroleum seep
(Marine Environmental Research, 2003-04-01)Previous studies at the Isla Vista oil seep have suggested that meiofauna, particularly nematodes, might be an important factor in explaining macrofaunal enrichment by making bacterial biomass available to the benthic food ... -
Reproductive success, xenobiotic contaminants and hepatic mixed-function oxidase (MFO) activity in Platichthys stellatus populations from San Francisco Bay
(Marine Environmental Research, 2003-04-01)To identify some specific effects of organic contaminants on fisheries in an urbanized estuary we compared the reproductive success of starry flounder from San Francisco Bay with concentrations of tissue contaminants and ... -
Partitioning radiolabeled thymidine uptake by bacteria and meiofauna using metabolic blocks and poisons in benthic feeding studies*
(Marine Biology, 1988)Techniques exist which allow for the measurement of in situ grazing rates of meiobenthos on sedimentary bacteria and microalgae. Radiolabeled substrates are incorporated into microbes which serve as food for meiofauna ... -
Meiofauna dispersal near natural petroleum seeps in the Santa Barbara channel: A recolonization experiment
(Oil & Chemical Pollution, 2005-03-10)Studies on the response of fauna to natural disturbances indicate that disturbance events may be important in structuring marine benthic communities. Benthic populations in the Santa Barbara Channel off Isla Vista, California ... -
Microbial biogeochemistry and heterotrophy in sediments of a marine hydrocarbon seep
(Limnology and Oceanography, 1989)Vertical profiles of sediment and pore-water constituents and rates of microbially mediated geochemical processes were determined in surficial sediments (0-7-cm depth) of three stations in and around Isla Vista hydrocarbon ... -
Monitoring long-term effects of offshore oil and gas development along the Southern California outer continental shelf and slope: Background environmental conditions in the Santa Maria Basin
(Oil & Chemical Pollution, 2005-03-10)Potential environmental impacts of materials discharged from oil and gas development and production platforms off the coast of southern California (Santa Maria Basin) are being monitored during an ongoing, long-term ... -
The effect on freshwater inflow on macrobenthos in the Lavaca River delta and upper Lavaca Bay, Texas
(Contributions in Marine Science, 1991)A two year study on the effects of freshwater inflow on macrobenthos at selected sites in the upper portion of the Lavaca River and Bay was conducted from November 1984 through August 1986. Lowest densities occurred in ... -
Meiobenthic communities of the Santa Maria Basin on the California continental shelf
(Continental Shelf Research, 2003-04-04)The Santa Maria Basin encompasses the bulk of the continental shelf off the central coast of California. Meiofauna communities on this shelf are very abundant. The average density of metazoa plus protozoans to a sediment ... -
The effect of freshwater inflow on meiofaunal consumption of sediment bacteria and microphytobenthos in San Antonio Bay, Texas, U.S.A.
(Estuarine and Coastal Shelf Science, 2004-11-19)If meiofauna are food-limited then they should respond with increased feeding rates when microbial production is stimulated. River inflow into estuaries is a source of organic matter that can be limiting to bacterial ... -
Photosynthetic response of natural assemblages of marine benthic microalgae to short- and long-term variations of incident irradiance in Baffin Bay, Texas.
(Journal of Phycology, 1992-02)This study was designed to understand the high variability characterizing primary production rates of microphytobenthos. The photosynthetic efficiency (αB) and photosynthetic capacity (PBmax) of the microphytobenthos were ... -
The effect of freshwater inflow on meiofaunal and macrofaunal populations in the Guadalupe and Nueces Estuaries, Texas
(Estuaries, 1992-09)Two estuaries with very different inflow characteristics were compared to test the hypothesis that benthic standing crops are enhanced by freshwater inflow. Assuming predation pressure is similar in both estuaries, this ...
