| 1 | A study of internal solitary waves observed on the continental shelf in the northwestern South China Sea显示文摘Based on in-situ time series data from the acoustic Doppler current profiler (ADCP) and thermistor chain in Wenchang area, a sequence of internal solitary wave (ISW) packets was observed in September 2005, propagating northwest on the continental shelf of the northwestern South China Sea (SCS). Corresponding to different stratification of the water column and tidal condition, both elevation and depression ISWs were observed at the same mooring location with amplitude of 35 m and 25 m respectively in different days. Regular arrival of the remarkable ISW packets at approximately the diurnal tidal period and the dominance of diurnal internal waves in the study area, strongly suggest that the main energy source of the waves is the diurnal tide. Notice that the wave packets were all riding on the troughs and shoulders of the internal tides, they were probably generated locally from the shelf break by the evolution of the internal tides due to nonlinear and dispersive effects. | XU Zhenhua YIN Baoshu HOU Yijun FAN Zhisong Antony K LIU | 2010 | Acta Oceanologica Sinica2010，29，3： | 17 |
| 2 | Analysis of characteristics and mechanism of current system on the west coast of Guangdong of China in summer显示文摘On the basis of data of drifting bottles’ tracks and the current measured in anchored stations, as well as temperature and salinityobserved in cruise investigations and coastal stations, ADCP current data and AVHRR surface sea temperature (SST) data on thewestern coast of Guangdong, synthetic results of analysis showed that the coastal currents in the west of the mouth of the ZhujiangRiver were mainly westward in summer, which constituted the north branch of cyclonic gyre in the east of the Qiongzhou Straits. Partof its water flowed westward into the Beibu Gulf through the Qiongzhou Straits. The coastal current pattern was not identical with thetraditional current system which flowed westward in the Qiongzhou Straits in winter and eastward in summer. The summertime’ scoastal current was always westward, maybe temporarily turning northeast only when the southwest wind was strong. The importantcharacteristics of coastal current on the western coast of Guangdong, in the Qiongzhou Straits and in the north of the Beibu Gulf wereanalyzed and their mechanisms also were explained. | BAO Xianwen HOU Yijun CHEN Changshen CHEN Fei SHI Maochong | 2005 | Acta Oceanologica Sinica2005，24，4： | 16 |
| 3 | Near-inertial waves in the wake of 2011 Typhoon Nesat in the northern South China Sea显示文摘In September 2011, Typhoon Nesat passed over a moored array of instruments recording current and temperature in the northern South China Sea(SCS). A wake of baroclinic near-inertial waves(NIWs) commenced after Nesat passed the array. The associated near-inertial currents are surface-intensified and clockwise-polarized. The vertical range of NIWs reached 300 m, where the vertical range is defined as the maximum depth of the horizontal near-inertial velocity 5 cm/s. The current oscillations have a frequency of 0.709 9 cycles per day(cpd), which is 0.025 f higher than the local inertial frequency. The NIWs have an e-folding time-scale of 10 d based on the evolution of the near-inertial kinetic energy. The depth-leading phase of near-inertial currents indicates downward group velocity and energy flux. The estimated vertical phase velocity and group velocity are 0.27 and 0.08 cm/s respectively, corresponding to a vertical wavelength of 329 m. A spectral analysis reveals that NIWs act as a crucial process to redistribute the energy injected by Typhoon Nesat. A normal mode and an empirical orthogonal function analysis indicate that the second mode has a dominant variance contribution of 81%, and the corresponding horizontal phase velocity and wavelength are 3.50 m/s and 420 km respectively. The remarkable large horizontal phase velocity is relevant to the rotation of the earth, and a quantitative analysis suggests that the phase velocity of the NIWs with a blue-shift of 0.025 f overwhelms that of internal gravity waves by a factor of 4.6. | YANG Bing HOU Yijun | 2014 | Acta Oceanologica Sinica2014，33，11： | 14 |
| 4 | 30-W supercontinuum generation based on ZBLAN fiber in an all-fiber configuration显示文摘We report an all-fiberized 30-W supercontinuum(SC) generation in a piece of ZrF4-BaF2-LaF3-AlF3-NaF(ZBLAN) fiber. The pump source is a thulium-doped fiber amplifier(TDFA) with broadband output spectrum spanning the 1.9 to 2.6 μm region. The used ZBLAN fiber has a core diameter of 10 μm, and was directly fusion-spliced to the pigtail of the TDFA without using a traditional mode field adapter(MFA) or a piece of transition fiber. Such a low-loss and robust fusion splice joint, together with a robust AlF3-fiber-based endcap,enables efficient and high-power SC generation in the ZBLAN fiber. An SC with an average power up to 30.0 W and a spectral coverage of 1.9–3.35 μm with 20-dB bandwidth of 1.92–3.20 μm was obtained. Moreover, an SC with a broader spectrum was achieved by raising the pump pulse peak power(via reducing the duty ratio of the pump laser pulse). An SC with an output power of 27.4 W and a spectral coverage of 1.9–3.63 μm(with 20-dB bandwidth of 1.92–3.47 μm) was obtained, as well as an SC with output power of 24.8 W and a spectral coverage of 1.9–3.70 μm(with 20-dB bandwidth of 1.93–3.56 μm). The power conversion efficiency was measured as>69%. To the best of the authors’ knowledge, this research demonstrates the record output power of SC lasers based on ZBLAN fibers, paving the way for broadband and efficient multi-tens-of-watts SC generation in softglass fibers. | LINYONG YANG YING LI BIN ZHANG TIANYI WU YIJUN ZHAO JING HOU | 2019 | Photonics Research2019，7，9： | 9 |
| 5 | The net primary productivity of Mid-Jurassic peatland and its control factors: Evidenced by the Ordos Basin显示文摘Using the large-scale thick 4# coal seam from the Mid-Jurassic in the southern Ordos Basin as an example, this paper studied the net primary productivity(NPP) level of the Mid-Jurassic peatland, and discussed its control factors. Geophysical logging signals were used for a spectrum analysis to obtain the Milankovitch cycle parameters in coal seam. These were then used to calculate the accumulation rate of the residual carbon in 4# coal seam. The carbon loss can be calculated according to the density and residual carbon content of 4# coal seam. Then, the total carbon accumulation rate of the peatland was further derived, and the NPP of peatland was determined. The results show that the NPP of MidJurassic peatland is higher than that of Holocene at the same latitude. Comprehensive analysis indicates that the temperature, carbon dioxide and oxygen levels in atmosphere are the main control factors of the NPP of Mid-Jurassic peatland. | Wang Dongdong Yan Zhiming Liu Haiyan Lv Dawei Hou Yijun | 2018 | International Journal of Mining Science and Technology2018，28，2： | 7 |
| 6 | The three-dimensional structure and seasonal variation of the North Pacific meridional overturning circulation显示文摘The three-dimensional structure and the seasonal variation of the North Pacific meridional overturning circulation (NPMOC) are analyzed based on the Simple Ocean Data Assimilation data and Argo profiling float data.The NPMOC displays a multi-cell structure with four cells in the North Pacific altogether.The TC and the STC are a strong clockwise meridional cell in the low latitude ocean and a weaker clockwise meridional cell between 7°N and 18°N,respectively, while the DTC and the subpolar cell are a weaker anticlockwise meridional cell between 3°N and 15°N and a weakest anticlockwise meridional cell between 35°N and 50°N,respectively. The DTC,the TC and the STC are all of very strong seasonal variations.As to the DTC, the southward transport is strongest in fall and weakest in spring.For the TC,the northward transport is strongest in winter and weakest in spring,while the southward transport is strongest in fall and weakest in spring, which is associated with the strong southward flow of the DTC in fall.As the STC,the northward transport is strongest in winter and weakest in summer,while the southward transport is strongest in summer and weakest in spring. This seasonal difference may be associated with the DTC.The zonal wind stress and the east-west slope of sea level play important roles in the seasonal variations of the TC,the STC and the DTC. | LIU Hongwei ZHANG Qilong DUAN Yongliang HOU Yijun | 2011 | Acta Oceanologica Sinica2011，30，3： | 7 |
| 7 | Eddy properties in the Pacific sector of the Southern Ocean from satellite altimetry data显示文摘Mesoscale eddies play a key role in the ocean dynamics of the Southern Ocean, and eddy response to the climate changes has also been widely noted. Both eddy kinetic energy(EKE) and eddy detection algorithm are used to study the eddy properties in the Pacific sector of the Southern Ocean. Consistent with previous works,the maps of the EKE illustrate that higher energy confines to the Antarctic Polar Frontal Zone(APFZ) and decreases progressively from west to east. It also shows that the most significant increase in the EKE occurs in the western and central parts of the Pacific sector, where the baroclinicity of the Antarctic Circumpolar Current(ACC) is much stronger. Statistical eddy properties reveal that both of the spatial pattern and interannual variation of the EKE are primarily due to the eddy amplitude and the eddy rotational speed, rather than the eddy number or the eddy radius. In general, these results furtherly confirm that anomalous westerly wind forcing associated with the positive Southern Annular Mode(SAM) index enhances the Southern Ocean eddy activity by strengthening the eddy properties. | DUAN Yongliang LIU Hongwei YU Weidong HOU Yijun | 2016 | Acta Oceanologica Sinica2016，35，11： | 5 |
| 8 | Tropical storm-forced near-inertial energy dissipation in the southeast continental shelf region of Hainan Island显示文摘Near-inertial motion is an important dynamic process in the upper ocean and plays a significant role in mass, heat, and energy transport across the thermocline. In this study, the dissipation of wind-induced near-inertial energy in the thermocline is investigated by using observation data collected in July and August 2005 during the tropical storm Washi by a moored system at(19°35′N, 112°E) in the continental shelf region off Hainan Island. In the observation period, the near-inertial part dominated the observed ocean kinetic energy and about 80% of the near-inertial energy dissipated in the upper layer. Extremely strong turbulent mixing induced by near-inertial wave was observed in the thermocline, where the turbulent energy dissipation rate increased by two orders of magnitude above the background level. It is found that the energy loss of near-inertial waves in the thermocline is mainly in the large-scales. This is different from the previous hypothesis based on 'Kolmogorov cascade' turbulence theory that the kinetic energy is dissipated mainly by small-scale motions. | ZHANG ShuWen XIE LingLing ZHAO Hui HOU YiJun | 2014 | Science China Earth Sciences2014，57，8： | 5 |
| 9 | Wind vector retrieval using dual polarization imagery of ASAR显示文摘A new algorithm for retrieving wind vector using dual polarization imagery of advanced synthetic aperture radar (ASAR) is developed and tested. Based on the combination of co-polarization and cross-polarization, this new algorithm effectively eliminates the 180° ambiguity which occurs when using single imagery of the ASAR to retrieve wind vector. This algorithm also solves the problem that the retrieval results will break down on very small spatial scales. The results retrieved from dual polarization imagery of ASAR show that the wind speed and direction are in agreement with the data from Quikscat and buoy measurements. The root mean square errors of wind direction and speed between the retrieved results and data from Quikscat are 2.21° and 0.53 m/s, respectively. Comparisons between the new method and the traditional method show that the new methods fit the buoy data and Quikscat data a little better than the traditional method in this image. | SONG Guiting HOU Yijun QI Peng | 2006 | Progress in Natural Science:Materials International2006，16，11： | 5 |
| 10 | Effects of large-amplitude internal solitary waves on ROV operation--A numerical study显示文摘Remotely operated vehicles(ROVs) are unique tools for underwater industrial exploration and scientific research of offshore areas and the deep ocean. With broadening application of ROVs, the study of factors that affect their safe operation is important. Besides the technical skills to control ROV movement, the dynamical ocean environment may also play a vital role in the safe operation of ROVs. In this paper, we investigate the influence of large-amplitude internal solitary waves(ISWs), focusing on the forces exerted on ROVs by ISWs. We present a methodology for modeling ISW-induced currents based on Kd V model and calculate the ISW forces using the Morrison equation. Our results show that an extremely considerable load is exerted by the ISW on the ROV, resulting in a strong disturbance of the vehicle's stability, affecting the ROV control. The numerical results of this work emphasize the importance of considering dynamical conditions when operating underwater vessels, such as ROV. Further laboratory and field investigation are suggested to gain more understanding of this subject. | SHEN Hui HOU YiJun | 2016 | Science China Earth Sciences2016，59，5： | 5 |
| 11 | Numerical simulation and preliminary analysis of typhoon waves during three typhoons in the Yellow Sea and East China Sea显示文摘In this study,typhoon waves generated during three typhoons(Damrey(1210),Fung-wong(1416),and Chan-hom(1509))in the Yellow Sea and East China Sea were simulated in a simulating waves nearshore(SWAN)model,and the wind forcing was constructed by combining reanalyzed wind data with a Holland typhoon wind model.Various parameters,such as the Holland fitting parameter(B)and the maximum wind radius?,were investigated in sensitivity experiments in the Holland model that affect the wind field construction.Six different formulations were considered and the parameters determined by comparing the simulated wind results with in-situ wind measurements.The key factors affecting wave growth and dissipation processes from deep to shallow waters were studied,including wind input,whitecapping,and bottom friction.Comparison with in-situ wave measurements suggested that the KOMEN scheme(wind input exponential growth and whitecapping energy dissipation)and the JONSWAP scheme(dissipation of bottom friction)resulted in good reproduction of the significant wave height of typhoon waves.A preliminary analysis of the wave characteristics in terms of wind-sea and swell wave revealed that swell waves dominated with the distance of R to the eye of the typhoon,while wind-sea prevailed in the outer region up to six to eight times the R values despite a clear misalignment between wind and waves.The results support the hypothesis that nonlinear wave-wave interactions may play a key role in the formation of wave characteristics. | WANG Ning HOU Yijun LI Shuiqing LI Rui | 2019 | Journal of Oceanology and Limnology2019，37，6： | 5 |
| 12 | Spectrally flat supercontinuum generation in a holmium-doped ZBLAN fiber with record power ratio beyond 3μm显示文摘A spectrally flat mid-infrared supercontinuum(MIR-SC) spanning 2.8–3.9 μm with a maximum output power of 411 mW was generated in a holmium-doped ZBLAN fiber amplifier(HDZFA). A broadband fiber-based SC covering the 2.4–3.2 μm region was designed to seed the amplifier. Benefiting from the broadband seed laser,the obtained SC had a high spectral flatness of 3 dB over the range of 2.93–3.70 μm(770 nm). A spectral integral showed that the SC power beyond 3 μm was 372 mW, i.e., a power ratio of 90.6% of the total power. This paper,to the best of our knowledge, not only demonstrates the first spectrally flat MIR-SC directly generated in fluoride fiber amplifiers, but also reports the highest power ratio beyond 3 μm obtained in rare-earth-doped fluoride fiber until now. | LINYONG YANG BIN ZHANG KE YIN TIANYI Wu YIJUN ZHAO JING Hou | 2018 | Photonics Research2018，6，5： | 4 |
| 13 | Response of the western North Pacific subtropical ocean to the slow-moving super typhoon Nanmadol显示文摘Based on in-situ observation,satellite and reanalysis data,responses of the western North Pacific subtropical ocean(WNPSO)to the slow-moving category 5 super typhoon Nanmadol in 2011 are analyzed.The dynamical response is dominated by near-inertial currents and Ekman currents with maximum amplitude of 0.39m/s and 0.15m/s,respectively.The near-inertial currents concentrated around 100m below the sea surface and had an e-folding timescale of 4 days.The near-inertial energy propagated both upward and downward,and the vertical phase speed and wavelength were estimated to be 5m/h and 175m,respectively.The frequency of the near-inertial currents was blue-shifted near the surface and redshifted in ocean interior which may relate to wave propagation and/or background vorticity.The resultant surface cooling reaches-4.35℃ and happens when translation speed of Nanmadol is smaller than 3.0m/s.When Nanmadol reaches super typhoon intensity,the cooling is less than 3.0℃ suggesting that the typhoon translation speed plays important roles as well as typhoon intensity in surface cooling.Upwelling induced by the slow-moving typhoon wind leads to typhoon track confined cooling area and the right-hand bias of cooling is slight.The mixed layer cooling and thermocline warming are induced by wind-generated upwelling and vertical entrainment.Vertical entrainment also led to mixed layer salinity increase and thermocline salinity decrease,however,mixed layer salinity decrease occurs at certain stations as well.Our results suggest that typhoon translation speed is a vital factor responsible for the oceanic thermohaline and dynamical responses,and the small Mach number(slow typhoon translation speed)facilitate development of Ekman current and upwelling. | YANG Bing HOU Yijun LI Min | 2019 | Journal of Oceanology and Limnology2019，37，3： | 3 |
| 14 | Fronts,baroclinic transport,and mesoscale variability of the Antarctic Circumpolar Current in the southeast Indian Ocean显示文摘Fronts,baroclinic transport,and mesoscale variability of the Antarctic Circumpolar Current(ACC) along 115°E are examined on the basis of CTD data from two hydrographic cruises occupied in 1995 as a part of the World Ocean Circulation Experiment(WOCE cruise I9S) and in 2004 as a part of CLIVAR/CO2 repeat hydrography program.The integrated baroclinic transport across I9S section is(97.2×106±2.2×106) m3/s relative to the deepest common level(DCL).The net transport at the north end of I9S,determined by the south Australian circulation system,is about 16.5×106m3/s westward.Relying on a consistent set of water mass criteria and transport maxima,the ACC baroclinic transport,(117×106 ±6.7×10 6)m3/s to the east,is carried along three fronts:the Subantarctic Front(SAF) at a mean latitude of 44°-49°S carries(50.6×10 6 ±13.4×106)m3/s;the Polar Front(PF),with the northern branch(PF-N) at 50.5°S and the southern branch(PFS) at 58°S,carries(51.3×106 ±8.7×106)m3/s;finally,the southern ACC front(SACCF) and the southern boundary of the ACC(SB) consist of three cores between 59°S and 65°S that combined carry(15.2×106 ±1.8×106)m3/s.Mesoscale eddy features are identifiable in the CTD sections and tracked in concurrent maps of altimetric sea level anomalies(SLA) between 44°-48°S and 53°-57°S.Because of the remarkable mesoscale eddy features within the SAF observed in both the tracks of the cruises,the eastward transport of the SAF occurs at two latitude bands separating by 1°.Both the CTD and the altimetric data suggest that the mesoscale variability is concentrated around the Antarctic Polar Frontal Zone(APFZ) and causes the ACC fronts to merge,diverge,and to fluctuate in intensity and position along their paths. | DUAN Yongliang HOU Yijun LIU Hongwei HU Po | 2012 | Acta Oceanologica Sinica2012，31，6： | 2 |

| 16 | Seasonal characteristics of internal tides and their responses to background currents in the Luzon Strait显示文摘The spatial-temporal characteristics of internal tides(ITs) in the southwest Luzon Strait are examined, based on9-month mooring current records from autumn 2008 to summer 2009. The results of spectral analysis show that the ITs in diurnal and semidiurnal frequencies are prominent at the mooring site, especially for the clockwise rotary component. The diurnal ITs are mostly dominated by the first mode except for that in spring when the second mode is relatively predominant. The semidiurnal ITs display a variable multimodal structure. Moreover,an apparent difference is detected in the kinetic energy of diurnal ITs. The energy is strongest in winter, and followed by that in summer, whereas the value is smallest in spring and autumn. It is suggested that the incoherent motions are responsible for the significant seasonal variations of diurnal ITs, reflecting interaction between diurnal ITs and the varying background conditions. However, the semidiurnal ITs are independent of seasonal change, whose energy is smaller and only one-third of the diurnal energy in winter. Nevertheless, the abnormal variations of semidiurnal ITs are also related to the variable background conditions. The incoherent semidiurnal constituent accounts for about 37% of the total semidiurnal tidal kinetic energy, but the diurnal tidal motions contain fewer incoherent component(22.2%). | FANG Yong HOU Yijun JING Zhiyou | 2015 | Acta Oceanologica Sinica2015，34，11： | 2 |
| 17 | Analysis of the relationship between bile duct and duodenal microbiota reveals that potential dysbacteriosis is the main cause of primary common bile duct stones显示文摘Bacteria play an important role in the formation of primary Common Bile Duct(CBD)stones.However,the composition and function of the microbiota of bile duct in patients with primary CBD stones remained to be explored.We utilized the 16S rRNA gene high-throughput sequencing technology to analyze the microbial diversity and community composition of biliary and duodenal microbiota in 15 patients with primary CBD stones and 4 patients without biliary tract diseases.Alpha diversity analysis showed that the microbiota richness was similar in bile and intestinal fluid;Beta diversity analysis showed that there were differences in the composition between biliary microbiota and the duodenal microbiota,but the abundance of the main groups showed similarities.The composition of the biliary microbiota from gallstone patients was more complex,as was the duodenal microbiota.Proteobacteria and Firmicutes were the dominant bacteria at phylum level,accounting for at least 75%of the total reads in each subgroup.Pseudomonas and EscherichiaShigella were the major genus among subgroups,but Escherichia-Shigella had increased abundance in duodenal microbiota with primary choledocholithiasis,which may play an important role in stone formation.It is noteworthy that Clostridiumsensu_stricto,Lachnospiraceae_UCG-008,Butyrivibrio and Roseburia which could produce short chain fatty acids(SCFAs),were significantly decreased in biliary microbiota with primary CBD stones(p<0.05).Our study provided new insights into the compositional of normal biliary microbiota.The micro-ecology of biliary and duodenal in patients with stones is complex and closely related,and there is a potential for dysbacteriosis.The decrease in abundance of certain major acid-producing bacteria affects the health of the biliary tract and thus leads to the formation of stones. | Zhitang Lyu Tingting Yu Lichao Zhang Xiaona Xu Yijun Zhang Jihong Li Zhirong Li Wei Zhang Senlin Hou | 2021 | Synthetic and Systems Biotechnology2021，6，4： | 2 |
| 18 | Response of Internal Waves to 2005 Typhoon Damrey over the Northwestern Shelf of the South China Sea显示文摘Continuous observation of sea water temperature and current was made at Wenchang Station(19°35′N,112°E) in 2005. The data collected indicate vigorous internal waves of both short periods and tidal and near-inertial periods. The temperature and current time series during 18-30 September were examined to describe the upper ocean internal wave field response to Typhoon Damrey(0518) . The strong wind associated with the typhoon,which passed over the sea area about 45 km south of Wenchang Station on 25 September,deepened the mixed layer depth remarkably. It decreased the mixed layer temperature while increasing the deep layer temperature,and intensified the near-inertial and high-frequency fluctuations of temperature and current. Power spectra of temperature and current time series indicate significant deviations from those obtained by using the deep ocean internal wave models characterized by a power law. The frequency spectra were dominated by three energetic bands:around the inertial frequency(7.75× 10-6 Hz) ,tidal frequencies(1.0×10-5 to 2.4×10-5 Hz) ,and between 1.4×10-4 and 8.3×10-4 Hz. Dividing the field data into three phases(before,during and after the typhoon) ,we found that the typhoon enhanced the kinetic energy in nearly all the frequency bands,especially in the surface water. The passage of Damrey made a major contribution to the horizontal kinetic energy of the total surface current variances. The vertical energy density distribution,with its peak value at the surface,was an indication that the energy injected by the strong wind into the surface current could penetrate downward to the thermocline. | WANG Gang QIAO Fangli HOU Yijun DAI Dejun LIN Min ZHANG Qilong WANG Gang YIN Baoshu | 2008 | Journal of Ocean University of China2008，7，3： | 2 |
| 19 | The water mass variability and southward shift of the Southern Hemisphere mid-depth supergyre显示文摘The Southern Hemisphere subtropical supergyre at intermediate depths connects all three ocean basins and plays a significant role in responding and conveying the climate-change-related variations in the global ocean.On the basis of the Simple Ocean Data Assimilation(SODA)ocean reanalysis,the thermohaline variability and southward shift of the mid-depth supergyre are demonstrated.The steric height of the subsurface relative to 1 500 m(400–1 500 m)from the SODA depicts exactly the flow patterns and variability of the oceanic supergyre.During 1958–2007 the water masses in the gyre interiors become cooler/fresher,with the significant exceptions of the Agulhas Current system and Agulhas leakage.The results also exhibit a pronounced strengthening of the inter-basin connection of the supergyre,and the strongest southward shift,by about 2.5 over the whole period,occurs in the central-south Pacific,which is associated with the changes in the basin-scale wind forcing. | DUAN Yongliang HOU Yijun LIU Hongwei LIU Yahao | 2013 | Acta Oceanologica Sinica2013，32，11： | 2 |
