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

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
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.

Characterization Of Legume Starches And Their Noodle Quality, Wen-Chieh Sung, Martha Stone
Journal of Marine Science and Technology
Physicochemical properties of starches isolated from Colorado grown legumes (chick peas, peanut beans, and pinto beans) were studied to find a feasible, less expensive source for making starch noodles. Surfactants, monoglycerides of fatty acids and sodium stearoyl lactylate at 0.5% of starch weight, were also combined with raw starch to prepare starch noodles. Cooking qualities of pinto bean and peanut bean starches were inferior to those of mung bean and/or chick pea starch noodles. Although mung bean starch is used commercially for making starch noodles, functional characteristics and sensory results on chick pea starch noodles show that chick peas are …
