- 摘要：A numerical model is applied here to simulate the transport of SS (suspended sediment). The whole model mainly consists of two parts: One is the hydrodynamic model, the synchronous coupling of a modified second-generation wave model and a two-dimensional tide-storm-surge mode, which provides the wave factors, 2-D current velocity and the sea surface elevation, and is used to study the interaction of waves, current, and storm surge. Storm-induced currents clearly affect the wave characteristics especially the wave height. The other is the SSC model, which uses the current data acquired from the above model to drive the movement of the SS, to simulate the distribution of SS. In the period of strong wind and surge, the SSC varies much more than that driven by pure tidal currents, especially in the coastal zone, where wave also plays an important role in the process of SS transport, and can increase the SS greatly. Here we apply this model system to simulate the transport of the SS discharged from the Yellow river. The results showed that: the high SSC area is around the Yellow River Mouth. There are two branches of SPM from the Yellow River. One goes into the Bohai Gulf along its southern coast, while the other into the Laizhou Gulf and then transports out of the Bohai Sea through the Bohai Strait.

发布时间：2023-04-28 - 摘要：A coupled sea ice-mixed layer-isopycnal model (OPYC, alias PIPE) was applied to simulate the circulation in the Southern Ocean. The model domain covered the Southern Ocean south of 24°S. The model was first spun up in a coarse resolution grid (2°longitude×1°latitude) for 40 years running; then was shifted in to a fine resolution grid (1°longitude×0.5°latitude with a focus in the Indian Sector and the Antarctic Marginal Sea) for additional 5 years running in order to create the detailed circulation pattern in the area of interest. The simulated annual averaged volume transport through Drake Passage was 145.3×106 m3/s and more similar to the observed result (134×106 m3/s) than FRAMS result (about 200×106 m3/s). The simulated results of circulation and sea ice also agreed with those of previous results. The meridional stream function and meridional transport obtained from the simulated results were used to study the meridional characteristics of the Antarctic Circumpolar Current (ACC).

发布时间：2023-04-28 - 摘要：The variation characteristics of SST in the east area of the western Pacific warm pool and its influence on the summer precipitation in Shandong Province were analyzed based on the monthly mean SST data in the Pacific during 1950-1998 and the monthly precipitation data in Shandong Province from 1961 to 1999. The results showed that the SST in the east area of the Warm Pool had obviously seasonal and interannual changes; and that there was a negative relation between the SST in the east area of the Warm Pool in May and the summer precipitation in Shandong Province. The primary analysis indicated that the SST in the east area of the Warm Pool affected the summer precipitation in Shandong Province, which is mainly linked through the variation of the Western Pacific Subtropical High.

发布时间：2023-04-28 - 摘要：The spatial and temporal variabilities of summer rainfall over Shandong for the period 1961-2000 were analyzed by EOF and wavelet analysis. The links between the variabilities of the rainfall and the Western Tropical Pacific Warm Pool areas thermal state and the summer monsoon were studied by SV D. The results showed that there are mainly 3 patterns of summer rainfall in Shandong, one of which is important that present in-phase variance of rainfall over all Shandong; besides it, there still exist the distributive differences between eastern and western: northern and southern. Variability of summer rainfall over Shandong is very closely links to the thermal state in the Western Tropical Pacific Warm Pool area. When the Western Tropical Pacific Warm Pool is warmer than normal, summer rainfall throughout Shandong is heavy, and vice versa. The impact of the thermal state variations in the Western Tropical Pacific Warm Pool area on the summer rainfall in Shandong seems to be through the changes in position of the western Pacific subtropical high and intension of the east Asian summer monsoon.关键词：summer rainfall;warm pool;monsoon

发布时间：2023-04-28 - 摘要：With the vertical velocity obtained by POM for simulating the circulation in the East China Seas, the upwelling and downwelling in the Changjiang River Mouth area are discussed. This simulation showed convincingly that upwelling exists in the area of the northern part of the Changjiang River Mouth; and that the downwelling which exists in its southern part which separates the upwelling at the Chang jiang River Mouth from the Men and Zhe coastal upwelling. This simulation showed that the upwelling at the Chang jiang River Mouth is caused by interaction of the Taiwan Warm Current with the slope bottom topography; and that southwest the monsoon in summer can strengthen the upwelling at the Changjiang River Mouth and the Men and Zhe coastal upwelling.关键词：Chang jiang River Mouth;upwelling;numerical simulation

发布时间：2023-04-28 - 摘要：The Princeton Ocean model was used to simulate the circulation in the Huanghai Sea and East China Sea and its annual cycle showing that: (1)A weak countercurrent exists on the left side of the Kuroshio. The countercurrent separates from the main stream of the Kuroshio around 30°N, 128°E, flows southwestward along isobaths, meets with the offshore branch of the Taiwan Warm Current around 28°N, 124°E, then returns back and joins the main stream, thus forming a cyclonic circulation. (2) The Taiwan Warm Current has an inshore branch and an offshore branch. Only in summer, the inshore branch can reach to about 30°N, where separates into two branches; one flows northward Changjiang River mouth, the other flows eastward, to be one of the sources of the Tsushima Warm Current. (3) The Tsushima Warm Current has multiple-sources. (4) In summer, Huanghai Sea Warm Current does not enter the southern Huanghai Sea. It mainly origins from the middle shelf flow in seasons other than autumn, in summer, it seemingly comes from the extension of the inshore branch of the Taiwan Warm Current. (5) The Eddy in the northern East China Sea exists all year round, with a closing cyclonical circulation in winter and summer. The seasonal variation of the eddy is influenced by the components of the cyclonical circulation, such as the Huanghai Sea Warm Current and middle shelf flow.

Up to now, most studies focus on total nitrogen (TN), organic nitrogen (ON) and inorganic nitrogen and could not yield integrated information on nitrogen cycling because different nitrogen forms contributing to their cyclings are different. In this work, nitrogen of Bohai Sea sediment in natural size was divided into transferable and untransferable parts by sequential extraction method for the first time. Estimation of transferable nitrogen and its function in sediment-water exchange showed that the contributions of different nitrogen forms in nitrogen recycling vary on time scale. Estimation indicated that IEF-N and OSF-N exist mostly at the surface of the sediment grain, and act as dominant participator in recycling, IMOF-N and CF-N are mainly present inside the sediment grain and contribute little to recycling. The nitrogen cycling budget for Bohai Sea shows that the contribution of pelagic recycling (74.4%) to primary productivity is much more than benthic recycling (26.1%). Analysis of the correlation between sediment nitrogen and primary product ion showed that it is very close. IEF-N acts as a "buffer pool" for nitrogen nutrient which can enhance primary productivity. Benthos bioturbation is conducive to enhancement of mineralization, which results in high NH4+ and NO3- distribution in deep sediments. Contribution of nitrogen forms in recycling varies on time scale. The absolute contribution of each state is consistent with its content in sediment, which has the sequence OSF-N (84.6%) > IEF-N (13.0) > IMOF-N (1.4%) CF-N (1.0%). Untransferable nitrogen account for 69.15% of TN, among which 49% is due to inclusion in sediment grain interior.

发布时间：2023-04-28 - 摘要：As the important resource and sink of biogenic element nitrogen, marine sediments have significant effect on nitrogen biogeochemical cycling. It is the key of this research to make clear nitrogen forms in sediments. Nitrogen biogeochemical cycling in marine sediments is a complex process. This research is focused on nitrogen early diagenesis, counter-eutrophication, nitrogen cycling (including mineralization, nitrification and denitrification), and nitrogen flux at the sediment-water interface. Various theory models and analysis methods have been built up. By now, systematic knowledge of nitrogen cycling has been obtained. Therefore, little was known about the distribution and forms of nitrogen, the relationship between nitrogen and other nutrients cycling, the effect of strong metals in nitrogen cycling. especially idiographic forms of nitrogen in different grain-size sediments in various sea areas. To research on the distribution and forms of nitrogen in sediments is the key for learning how nitrogen forms and transports in sediments, utilization and burying degree of nitrogen, the effect of nitrogen in the biological chain, and the relationship between nitrogen and marine biological activities. The effect of nitrogen on marine ecological evolvement and marine biogeochemical cycling must be deeply studied. The ocean is the last region rich in resources that has not been completely exploited. How to exploit it properly is an important problem.关键词：nitrogen forms;marine sediment;biogeochemical cycling

发布时间：2023-04-28 - 摘要：To save freshwater, people want to replace freshwater with seawater for cooling in industry. However, in seawater cooling system, the corrosion of the outlet of heat-exchanger and its following steel components is very serious. Application of Al sacrificial anode is one effective method to prevent steel equipment in seawater from corrosion, but at 50℃, Al anodes in common use are not applicable. So it is important to study the relevant rules governing Al anode performance at high temperature. Since the working potential is an important factor affecting the performance of Al anode, we try to find the rules governing how additional elements affect the working potential at various temperature. Twenty-eight kinds of Al sacrificial anode were made for the experiment by the method of the Chinese National Standard GB4948-85. The interrelation of additional elements in the Al anode and the working potential of anode were studied by the method of grey box analysis. The results showed that the influencing order of elements on the working potential was the same on the whole; and that In, Zn, Mg and Ga were good additional elements for aluminum sacrificial anode in order to get negative working potential.关键词：seawater cooling system;Al sacrificial anode

发布时间：2023-04-28 - 摘要：Paralytic shellfish poisoning (PSP) toxins are toxins produced by harmful red tide algae, such as some species of marine dinoflagellate and blue-green algae. PSP toxins, including saxitoxin and its derivatives are tetrahydro purines composed of two guanidinium functions. PSP toxins can selectively block the voltage-gated sodium channel of many excitable membranes. The 7, 8, 9-guanidinium moiety is essential for the blocking activity. PSP toxins can be used in many fields. In the study of red tide, purified PSP toxins can serve as standard toxins to analyze algal and shellfish samples. Development of new method for toxin-monitoring also needs purified PSP toxins. In studies of neurobiology and molecular biology, saxitoxin has been widely used as research tool. PSP toxins also show activities as local anesthetics, in treating cancer and so on. However, the functions still need to be confirmed and studied. In summary, PSP toxins have great potential for different applications despite the huge damages they have made in the past several decades.

发布时间：2023-04-28 - 摘要：Alexandrium tamarene can produce paralytic shellfish poisoning (PSP) toxins that can selectively block the voltage-gated sodium channel of many excitable membranes. Here we report the effect of PSP toxins crudely extracted from A.tamarense, on Na+M1196current at motor nerve terminals and whole cell Motor nerve terminals experiments were performed on mouse triangularis stemi nerve-muscle preparations. Presynaptic currents were picked up with a microelectrode inserted into the subendothelial space of the superficial nerve bundle under visual control using a×400 magnification water immersion objective. Patch-clamp whole cell recording configuration was used to study the effects of PSP toxins on the voltage gated Na+ current of differentiated NG 108-15 cells. The results showed that the PSP toxins clearly inhibited the voltage-gated sodium current of the mouse motor nerve terminals and the whole NG 108-15 cell; and that the effects were partially reversible. A dose of 1.15 nmol/L ST Xeq. PSP toxins can reversibly inhibit the voltage-gated sodium current of the mouse motor nerve terminals; a dose of 4.60 nmol/L. STxeq. PSP toxins can reversibly inhibit the voltage-gated sodium current of the whole NG108-15 cell while no inhibition effect on potassium current was observed. At the same experiment conditions, the reversible inhibitions of our prepared PSP toxins were the same as that of the standard saxitoxin on sodium current of the mouse motor nerve terminals and the whole NG 108-15 cell.关键词：PSP toxins;Na+ current;motor nerve terminals

发布时间：2023-04-28 - 摘要：Rapid growth of marine fish farming often leads to adverse impacts on the environment, especially the release of dissolved nutrients which may cause eutrophication. As an ecological treatment solution, large seaweeds can be used to get rid of the excess nutrients while obtaining higher output. A setup consisting of six 3m3 tanks (one with neither fish nor seaweeds, others with or without seaweeds) was used to investigate ecological function of M1213 As the experiment period was spring, Gracilaria lemaneiformis grew well even in the low nutrient environment; and had average specific growth rate (SGR) of 4.05% in the four polyculture tanks, with the highest one (4.5%) in the #4 tank. In addition. except the #3 tank, G.lemaneiformis had competitive advantage over phytoplankton after a period of time. At the same time, most of the dissolved nutrients (NO3-N, NO2-N, NH4-N, PO4-P) in the polyculture tanks were removed as the environmental dissolved inorganic nutrients (DIN) were much lower than those of the tank without G.lemaneiformis, whose average content was 2.53μmol/L. In order to achieve good water quality as well as high production, carrying capacity has to be considered according to existing system and conditions. In this experiment, 1:1 co-culture of G.lemaneiformis and Sebastodes fuscescens yielded good results.关键词：marine fish farming;polyculture of fish and seaweeds

发布时间：2023-04-28 - 摘要：The rotifer Brachionus plicatilis complex, including B.plicatilis O.F. Müller (formerly called L-type) and B.rotundiformis Tschugunoff (formerly called S-type) as an excellent live food for many species of marine fish larvae, has been widely used in most of the modern marine hatcheries in the world. Rotifer resting eggs (i.e. dormant eggs) are considered as the best or ideal form for storage and application of the rotifers in aquaculture. Numerous studies have been therefore carried out on the resting eggs especially on their dormancy and hatching. This paper reviews the relevant work on controlling factors of hatching, including both the internal factors (e.g. dormant period, genotype, and maternal culture history) and the external ones (e.g. preservation conditions and methods, preservation period, incubation conditions and sterilizing or processing of the eggs). The possible functional mechanisms of these factors for the hatching of resting eggs are also discussed.
