大亚湾养殖海区沉积物中营养盐的解吸——吸附 总被引：9，自引：0，他引：9
研究了天然海水体系大亚湾养殖海区表层沉积物营养盐的解吸－吸附规律。结果表明,沉积和扣磷酸盐和硅酸盐解吸２小时基本达到平衡,而铵盐、硝酸盐和亚硝酸盐０．５小时内基本达到平衡;各营养盐的解吸随ＰＨ值（小于８）降低而增大,随ＰＨ值（大于８）升高略有增加;盐度仅在低于１０时对各营养盐的解吸有影响。研究了磷酸盐在沉积物上的吸附等温线。 相似文献

根据１９８７年６，８，１１月和１９８８年２月４个航次珠江口伶汀洋的调查资料，分析了溶解氧的特征。结果表明：溶解氧含量表层均高于底层，周年变化呈现从夏季到冬季逐渐上升，且明显受珠江径流的影响，溶解氧（基本上是不饱和状态）与盐度成负相关。有机物和营养盐均影响溶解氧，但水温仍为溶解氧主要影响因素。 相似文献

The elements Al, Cd, Co, Cu, Ni and Zn were concentrated from seawater using tetraethylenepentamine resin and analysed by atomic absorption spectrophotometry. The spatial distribution of these elements in the northwest Atlantic Ocean is discussed with respect to possible riverine inputs to the area from Puerto Rico. 相似文献

Cross-Calibration and Long-Term Monitoring of the Microwave Radiometers of ERS,TOPEX, GFO,Jason, and Envisat 总被引：1，自引：1，他引：0
The radiometers on board the satellites ERS-1, TOPEX/Poseidon, ERS-2, GFO, Jason-1, and Envisat measure brightness temperatures at two or three different frequencies to determine the total columnal water vapor content and wet tropospheric path delay, a major correction to the altimeter range measurements. In order to asses the long-term stability of the path delay, the radiometers are calibrated against vicarious cold and hot references, against each other, and against several atmospheric models. Four of these radiometers exhibit significant drifts in at least one of the channels, resulting in yet unmodeled errors in path delay of up to 1 mm/year, thus limiting the accuracy at which global sea level rise can be inferred from the altimeter range measurements. 相似文献

Ag, Al, Ca, Cd, Cu, Fe, Mg, Mn, Pb and Zn concentrations and 210Po and 210Pb activities were measured in 26 specimens of the squid Nototodarus gouldi taken from the waters of Bass Strait in one jigging operation. All the elements show wide ranges in concentrations in specimens apparently subject to the same environmental conditions. Copper concentration was 27-1 200 μg/g, and 210Po activity 4·8–24·2 Bq/g. The animal wet weights, the elements Ag, Al, Cd, Fe and Zn, and the radionuclide 210Po have coefficients of variation in the range 40–60%; Ca, Mg and Mn show the smallest variability (CV = < 30%), and Cu the greatest (CV = 12%). Significant correlations (p < 0·001) were found between the following pairs of elements: Cd-Zn, Cd-Cu, Zn-Cu, Mg-Mn, Fe-Mn, Ca-Mg and Fe-210Po. 相似文献

This paper discusses remote sensing (RS) of the major types of water bodies by means of microwave radiometry. The analysis is based on theoretical models and experimental data taken under laboratory conditions, in a pool, from a shore, and over the oceans using aircraft and satellites. The radiation is found to depend on wind speed and the geometry of ripples, gravity waves, swell, foam, and some physical and chemical parameters of water such as its temperature, salinity, and concentration of some types of polutants. The estimates of the effectiveness of the microwave radiometric method for determining the above mentioned water-surface parameters are given. Examples of the application of microwave radiometry to obtaining operational information about some of them are also presented. The types of water observed are the inland waters, fresh or with a high concentration of salts, clean or polluted, and the oceans. The paper is based on the theoretical and experimental investigations conducted by the author and his colleagues at the Institute of Radio Engineering and Electronics of the Academy of Sciences in the USSR over the last 20 years. It also draws upon well-known Soviet and foreign publications. 相似文献

The current methods used in world practice for the determination of the basic parameters of the vital functions of bacterioplankton
(the number, biomass, and production) are discussed. While comparing the different methods and their modifications, the peculiarities
of their application for particular natural or laboratory environments are emphasized. The specificity of applying different
microbiological methods for field research is examined. When choosing the methodological base for describing the characteristics
of a bacterial community, one should proceed from the specific problem facing the researcher. In the case of routine monitoring,
the following techniques are convenient and widely used: direct counts of DAPI fluorochrome-stained bacteria using a fluorescence
microscope; the calculation of the biomass of the microorganisms on the basis of the relationship between the cell’s mass
and its size; the estimation of the bacteria production via labeled leucine incorporation. 相似文献
