A Trophic Model For Kuosheng Bay In Northern Taiwan, Hsing-Juh Lin, Kwang-Tsao Shao, Jiang-Shiou Hwang, Wen-Tseng Lo, I-Jiunn Cheng, Lih-Huwa Lee

Journal of Marine Science and Technology

Using the Ecopath with Ecosim software system, a mass-balanced trophic model of Kuosheng Bay, where the Second Nuclear Power Plant is sited on the coast, was constructed. This model comprised 17 compartments, ranging from a trophic level of 1.00 for primary producers and detritus to 3.97 for piscivorous fish. The geometric mean of the trophic transfer efficiencies was 6.5%. The lower efficiencies were attributable to high flows to detritus, suggesting that the food web was more dependent on detritus than on primary producers to generate total system throughput. The total system throughput, system production, and system biomass were comparable to …

The Coastal Currents Offshore The Nuclear Power Plants At Northern Taiwan, Jian-Hwa Hu

Journal of Marine Science and Technology

Coastal tidal currents play an important role to disperse the warm waters outlet from cooling system of a nuclear power plant (NPP). The modern technique of ship-board acoustic Doppler current profiler (SB-ADCP) was intensively applied to scan the current fields around the three NPPs at northern Taiwan. Sophisticated data processing provides time series of synoptic flow charts of vectors in grids associated with streamlines, allowing the visualization of how the bay like coastline input its boundary layer effect to the current field. The generation of cyclonic or anti-cyclonic vortices inside the bay in flood or ebb tide and their migration …

Journal of Marine Science and Technology

Circulation and hydrographic variations in the inner shelf of a semi-enclosed bay adjacent to a nuclear power plant of the southernmost Taiwan were analyzed using intensive observation data from 2003-2004. The dominant tide in the bay is a mixture of diurnal and semidiurnal components. Currents are dominated by tidal forcing which flows southwestward during flood and northeastward during ebb. The amplitudes of tidal currents range from 0.2 to 0.4 m/s. A persistent southwestward subtidal flow is present with a mean velocity of 0.15 m/s. The upwelled cold deep water in the central bay can intrude to the inner reach near …


Upwelling And Degree Of Nutrient Consumption In Nanwan Bay, Southern Taiwan, Chen-Tung Arthur Chen, Bing-Jye Wang, Li-Yu Hsing Oct 2004

Upwelling And Degree Of Nutrient Consumption In Nanwan Bay, Southern Taiwan, Chen-Tung Arthur Chen, Bing-Jye Wang, Li-Yu Hsing

Journal of Marine Science and Technology

The newly proposed Degree of Nutrient Consumption (DNC) of upwelled waters was used to evaluate the upwelling process in Nanwan Bay off the southern tip of Taiwan. DNC values were found to be low in subsurface waters or in newly upwelled waters. In general, a low DNC value was detected alongside other traditionally used upwelling indicators such as lower temperature, pH and % oxygen saturation but higher salinity, nutrients and chlorophyll a. On the other hand, the DNC value could be several times higher in aged upwelled water found in the surface layer.

Nest-Building And Spawning Behaviors In Nocomis Effusus (Actinopterygii: Cyprindae), Eugene G. Maurakis, George E. Maurakis

Virginia Journal of Science

Spawning behavior in Nocomis effusus is described from direct observations and review of videotapes made in Yellow Creek (Cumberland River drainage), Tennessee in 2003. Nest construction (i.e., excavating a concavity, forming a platform, and building a mound), and spawning behavior in N. effusus where a single breeding male excavates a pit and spawns with females on the upstream slope of his nest is like that described for Nocomis asper and Nocomis biguttatus. In digging a spawning pit, a male N. effusus reshapes and reorganizes substrate materials that results in spawning areas on the upstream slope of the nest composed …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Elevated phosphorus concentrations in aquatic ecosystems of northwest Arkansas prompted an investigation of the effects of sample preparation and extraction methods on laboratory measures of sediment-phosphorus interactions. Two streams of contrasting phosphorus (P) concentrations were selected to determine the effect of using a CaCl2 solution instead of filtered stream water, refrigerated or dried sediments instead of fresh wet sediments, and vortexing the suspensions instead of shaking them. Sediment equilibrium P concentration (EPC0) and P buffering capacity (K) were used to determine differences in extraction methods. EPC0 and K from extractions using fresh sediments and a CaCl2 solution matching the electrical …

Invasive plants decrease aboveground biodiversity and suitable wildlife habitat. Wetlands are especially valuable ecosystems because they provide habitat, floodwater control, and function as filters for urban runoff. Wetland soils also act as sinks for nutrients. This characteristic reduces levels of excess nutrients often found in adjacent aquatic systems. The importance of soil functions in wetlands necessitates further investigation of the effects of invasive species on belowground nutrient pools. Approximately 75% of a small neighborhood wetland located in Fayetteville, Ark., has been invaded by Lonicera japonica. The effects of L. japonica and its replacement with native grasses on soil microbial biomass …
