| 1 | Surface mass balance and its climate significance from the coast to Dome A, East Antarctica显示文摘Based on stake measurements conducted along the Chinese Antarctic traverse since Jan.1999,we investigated the characteristics of surface mass balance(SMB)and related climate consequences from Zhongshan Station to Dome A,East Antarctica.Spatial analysis suggests that post-depositional processes have a great impact on surface morphology;thus,the representativeness of a single measurement should be discussed in conjunction with local climate features.The comparison among snow accumulation,ice sheet thickness,surface elevation,and ice velocity indicates that the bedrock topography has an indirect connection with the SMB patterns through controlling the surface topography and local climate.The observation reveals that the Lambert Glacier Basin has been experiencing increasing mass input(4.5%),whereas the inland area has experienced a 6%loss,since 2005.An overall estimation of the SMB along the route is 71.3±44.3 kg m?2 a?1,but the annual and regional variation is considerable.Tendency analysis shows that there are four sections with different SMB patterns as a result of three moisture sources and surface climatic discrepancy in the Antarctic inland.This study is the first to identify four SMB patterns from the coast to the Dome area and should provide a valuable contribution to modeling and remote sensing on a continental scale. | DING MingHu XIAO CunDe LI ChuanJin QIN DaHe JIN Bo SHI GuiTao XIE AiHong CUI XiangBin | 2015 | Science China Earth Sciences2015，58，10： | 7 |
| 2 | Dating a 109.9 m ice core from Dome A (East Antarctica) with volcanic records and a firn densification model显示文摘A 109.9 m ice core was extracted at a location about 300 m away from the Dome A summit(80°00′S,77°21″E) by the Chinese team of the International Trans-Antarctic Science Expedition(ITASE) during the 21st Chinese National Antarctica Research Expedition(CHINARE) in January 2005.Two independent methods were used for dating the ice core,volcanic event markers shown by prominent non-sea-salt sulfate(nss-SO42) and the Herron and Langway(H-L) firn densification model.Six promi-nent volcanic events(Agung 1963 AD,Tambora 1815 AD,Kuwae 1453 AD,Unknown 1259 AD,Taupo 186 AD and Pinatubo 1050 BC) were identified by comparison with other Antarctic ice cores.Based on the mean accumulation rates be-tween adjacent events,we estimate the age at the firn pore close-off depth(102 m) was 3516±100 a BP.This is the oldest close-off age ever reported from the Antarctic and the Greenland ice sheets.Calculations using the H-L model show that the age at the same depth is 3581±100 a BP.The two dating techniques differ by 65 years,or~1.8% of the record.We calculated the bottom age of the ice core as 4009±150 a BP using the volcanic dating method and 4115±150 a BP using the H-L model method. | LI ChuanJin XIAO CunDe HOU ShuGui REN JiaWen DING MingHu GUO Rui | 2012 | Science China Earth Sciences2012，55，8： | 5 |
| 3 | A 2680-year record of sea ice extent in the Ross Sea and the associated atmospheric circulation derived from the DT401 East Antarctic ice core显示文摘Long time series of Antarctic sea ice extent(SIE) are important for climate research and model forecasting. A historic ice extent in the Ross Sea in early austral winter was rebuilt through sea salt ions in the DT401 ice core in interior East Antarctica. El Ni?o-Southern Oscillation(ENSO) had a significant influence on the sea salt deposition in DT401 through its influence on the Ross Sea SIE and the transport of sea salt inland. Spectral analysis also supported the influence of ENSO with a significant 2–6 a periodicity band. In addition, statistically significant decadal(10 a) and pentadecadal(50–70 a) periodicities suggested the existence of a teleconnection from the Pacific decadal oscillation(PDO), which originated from sea surface temperature anomalies in the tropical Pacific Ocean. The first eigenvector of the empirical orthogonal function analysis(EOF1) showed lower values during the Medieval Warm Period(MWP), while higher values were found in the Little Ice Age(LIA). A higher frequency of ENSO events were found in the cold climatic stage. The post 1800 AD period was occupied by significant fluctuations of the EOF1, and PDO may be one of the influencing factors. The EOF1 values showed moderate fluctuations from 680 BC to 1000 AD, showing that the climate was relatively stable in this period. | LI ChuanJin REN JiaWen XIAO CunDe HOU ShuGui DING MingHu QIN DaHe | 2015 | Science China Earth Sciences2015，58，11： | 4 |
| 4 | Factors controlling the nitrate in the DT-401 ice core in eastern Antarctica显示文摘Nitrate,an oxidized product of NO x preserved in the polar ice cores,has often been used to estimate past changes of the atmospheric nitrogen cycle.A 102.65 m ice core drilled at DT-401(79°01'S,77°00'E) in 1999 provides an opportunity to investigate the possible influencing factors for the nitrate budget in the eastern Antarctica.We studied the relationship between the δ18O(representing the temperature),accumulation rate,volcanic deposition and the astronomical factors(such as the solar activities,supernovae,etc.),and the nitrate variation along the whole duration(2680-year) of the ice core.Prominent impacts of the accumulation rate acting on the nitrate flux rather than the concentration were detected.However,no significant correlation was found between the δ18O and the nitrate deposition characteristics(concentration and the flux variations).Volcanic deposition can significantly affect the deposition of nitrate with a decreasing trend accompanied by the nss-SO42(volcanic signal) peak values.Impacts of the solar activities on the nitrate deposition can be detected at this site,and three prominent periodicities(16.6,24.0 and 102.0 yr) were found for the nitrate concentration variations.Six climatic events(Dalton Minimum,Maunder Minimum,Sporer Minimum,Wolf Minimum,Oort Minimum and Medieval Maximum) during the past 1150 years were observed with lower nitrate values for the foregoing five events and higher value for the last one. | LI ChuanJin REN JiaWen QIN DaHe XIAO CunDe HOU ShuGui LI YuanSheng DING MingHu | 2013 | Science China Earth Sciences2013，56，9： | 4 |
| 5 | Snowdrift effect on snow deposition:Insights from a comparison of a snow pit profile and meteorological observations in east Antarctica显示文摘A high-frequency and precise ultrasonic sounder was used to monitor precipitated/deposited and drift snow events over a 3-year period(17 January 2005 to 4 January 2008) at the Eagle automatic weather station site,inland Antarctica.Ion species and oxygen isotope ratios were also generated from a snow pit below the sensor.These accumulation and snowdrift events were used to examine the synchronism with seasonal variations of δ^(18)O and ion species,providing an opportunity to assess the snowdrift effect in typical Antarctic inland conditions.There were up to 1-year differences for this 3-year-long snow pit between the traditional dating method and ultrasonic records.This difference implies that in areas with low accumulation or high wind,the snowdrift effect can induce abnormal disturbances on snow deposition.The snowdrift effect should be seriously taken into account for high-resolution dating of ice cores and estimation of surface mass balance,especially when the morphology of most Antarctic inland areas is similar to that of the Eagle site. | DING MingHu ZHANG Tong XIAO CunDe LI ChuanJin JIN Bo BIAN LinGen WANG ShuJie ZHANG DongQi QIN DaHe | 2017 | Science China Earth Sciences2017，60，4： | 3 |
| 6 | Spatial and temporal variability of marine-origin matter along a transect from Zhongshan Station to Dome A,Eastern Antarctica显示文摘The spatiotemporal distribution pattern of marine-origin matter on the Antarctica ice sheet was used to study variations in the source regions, transport mechanisms and postdepositional influences. We present data on sea salt ions, sulfur components and stable isotopes from surface and snow pit samples collected along the transect route from Zhongshan Station to Dome A during the austral summer in 2012–2013. A general decreasing trend in the accumulation, sea salt ions and sulfur components occurred with increasing distance from the coast and increasing elevation. However, different sources of the marine components, transport pathways and post-depositional influences were responsible for their different spatial distribution patterns. The marine ions in the coastal snow pit varied seasonally, with higher sea salt ion concentrations in the winter and lower concentrations in the summer; the opposite pattern was found for the sulfur compounds. The sea ice area surrounding Antarctica was the main source region for the deposited sea salt and the open sea water for the sulfur compounds. No significant trends in the marine-origin components were detected during the past 3 decades. Several periods of elevated deposition of sea salt ions were associated with lower temperatures(based on δD and δ18O) or intensified wind fields. In comparison to the sea salt ions, the sulfur concentrations exhibited the opposite distribution patterns and were associated with changes in the surrounding sea ice extent. | Chuanjin Li Cunde Xiao Guitao Shi Minghu Ding Dahe Qin Jiawen Ren | 2016 | Journal of Environmental Sciences2016，28，8： | 3 |

| 8 | Iron in the NEEM ice core relative to Asian loess records over the last glacial–interglacial cycle显示文摘Mineral dust can indirectly affect the climate by supplying bioavailable iron(Fe)to the ocean.Here,we present the records of dissolved Fe(DFe)and total Fe(TDFe)in North Greenland Eemian Ice Drilling(NEEM)ice core over the past 110 kyr BP.The Fe records are significantly negatively correlated with the carbon-dioxide(CO_(2))concentrations during cold periods.The results suggest that the changes in Fe fluxes over the past 110 kyr BP in the NEEM ice core are consistent with those in Chinese loess records because the mineral-dust distribution is controlled by the East Asian deserts.Furthermore,the variations in the dust input on a global scale are most likely driven by changes in solar radiation during the last glacial–interglacial cycle in response to Earth’s orbital cycles.In the last glacial–interglacial cycle,the DFe/TDFe ratios were higher during the warm periods(following the post-Industrial Revolution and during the Holocene and last interglacial period)than during the main cold period(i.e.the last glacial maximum(LGM)),indicating that the aeolian input of iron and the iron fertilization effect on the oceans have a non-linear relationship during different periods.Although the burning of biomass aerosols has released large amounts of DFe since the Industrial Revolution,no significant responses are observed in the DFe and TDFe variations during this period,indicating that severe anthropogenic contamination has no significant effect on the DFe(TDFe)release in the NEEM ice core. | Cunde Xiao Zhiheng Du Mike J Handley Paul A Mayewski Junji Cao Simon Schüpbach Tong Zhang Jean-Robert Petit Chuanjin Li Yeongcheol Han Yuefang Li Jiawen Ren | 2021 | National Science Review2021，8，7： | 2 |
| 9 | Electrochemical performance of La_(2)NiO_(4+δ)-Ce_(0.55)La_(0.45)O_(2−δ)as a promising bifunctional oxygen electrode for reversible solid oxide cells显示文摘In this work,La_(2)NiO_(4+δ)-Ce_(0.55)La_(0.45)O_(2−δ)(denoted as LNO-xLDC)with various LDC contents(x=0,10,20,30,and 40 wt%)were prepared and evaluated as bifunctional oxygen electrodes for reversible solid oxide cells(RSOCs).Compared with the pure LNO,the optimum composition of LNO-30LDC exhibited the lowest polarization resistance(Rp)of 0.53 and 0.12Ω·cm^(2)in air at 650 and 750℃,respectively.The enhanced electrochemical performance of LNO-30LDC oxygen electrode was mainly attributed to the extended triple phase boundary and more oxygen ionic transfer channels.The hydrogen electrode supported single cell with LNO-30LDC oxygen electrode displayed peak power densities of 276,401,and 521 mW·cm^(−2)at 700,750,and 800℃,respectively.Moreover,the electrolysis current density of the single cell demonstrated 526.39 mA·cm^(−2) under 1.5 V at 800℃,and the corresponding hydrogen production rate was 220.03 mL·cm^(−2)·h^(−1).The encouraging results indicated that LNO-30LDC was a promising bifunctional oxygen electrode material for RSOCs. | Pengzhang Li Wei Yang Chuanjin Tian Wenyan Zhao Zhe Lü Zhipeng Xie Chang-An Wang | 2021 | Journal of Advanced Ceramics2021，10，2： | 2 |

| 11 | Elicitor hydrophobin Hyd1 interacts with Ubiquilin1-like to induce maize systemic resistance显示文摘Trichoderma harzianum is a plant-beneficial fungus that secretes small cysteine-rich proteins that induce plant defense responses;however, the molecular mechanism involved in this induction is largely unknown.Here, we report that the class Ⅱ hydrophobin Th Hyd1 acts as an elicitor of induced systemic resistance(ISR) in plants. Immunogold labeling and immunofluorescence revealed Th Hyd1 localized on maize(Zea mays) root cell plasma membranes. To identify host plant protein interactors of Hyd1, we screened a maize B73 root c DNA library. Th Hyd1 interacted directly with ubiquilin1-like(UBL). Furthermore, the N-terminal fragment of UBL was primarily responsible for binding with Hyd1 and the eight-cysteine amino acid of Hyd1 participated in the protein-protein interactions. Hyd1 from T. harzianum(Thhyd1) and ubl from maize were co-expressed in Arabidopsis thaliana, they synergistically promoted plant resistance against Botrytis cinerea. RNA-sequencing analysis of global gene expression in maize leaves 24 h after spraying with Curvularia lunata spore suspension showed that Thhyd1-induced systemic resistance was primarily associated with brassinosteroid signaling, likely mediated through BAK1. Jasmonate/ethylene(JA/ET)signaling was also involved to some extent in this response. Our results suggest that the Hyd1-UBL axis might play a key role in inducing systemic resistance as a result of Trichoderma-plant interactions. | Chuanjin Yu Kai Dou Shaoqing Wang Qiong Wu Mi Ni Tailong Zhang Zhixiang Lu Jun Tang Jie Chen | 2020 | Journal of Integrative Plant Biology2020，62，4： | 1 |
| 12 | Synthesis and Photocatalytic Activity of Fe-doped TiO_2 Supported on Hollow Glass Microbeads显示文摘In this paper, Fe-doped TiO_2 photocatalyst supported on hollow glass microbeads(Fe-TiO_2 /beads)is prepared by dip-coating method, which uses hollow glass microbeads as the carriers and tetrabutylorthotitanate [Ti(OC_4H_9)_4] as the raw material. The phase structure, ingredient, morphologies, particle size and shell thickness of the products are characterized by X-ray powder diffraction(XRD), energy-dispersive spectroscopy(EDS) and field emission scanning electron microscope(FESEM). The feasibility of photocatylic degradation of Rhodamine B(Rh B) under illumination of UV-vis light is studied. The results show that the core-shell structure catalyst is composed of Fe-doped anatase TiO_2 and hollow glass microbeads, and the catalytic activity of the TiO_2 is markedly enhanced by Fe ion doping. The optimum concentration of Fe ion is 0.1%(molecular fraction) in the precursor and the photocatalytic activity can be increased to 98% compared with that of the undoped one. The presence of ferrum elements neither influences the transformation of anatase to rutile, nor creates new crystal phases. The possible mechanism of photocatalytic oxidation is also discussed. | Wenyan Zhao Wuyou Fu Haibin Yang Chuanjin Tian Minghui Li Juan Ding Wei Zhang Xiaoming Zhou Hui Zhao Yixing Li | 2011 | Nano-Micro Letters2011，3，1： | 1 |

| 17 | Accumulation and geochemical evidence for the Little Ice Age episode in eastern Antarctica显示文摘Data on accumulation and concentration of chemical compounds recorded in an essentially unexplored area(Dome Argus)of the Indian Ocean sector of eastern Antarctica during the past 2,680 years(680 B.C. to 1999 A.D.) are presented. During the first 1, 700 years(680 B. C. to 1000 A. D.), the accumulation data shows a slightly decreasing trend, while chemical ions appear to be stable, representing a stable climatic condition. An intensive increasing trend of the accumulation occurred during the 12^(th) to 14^(th) century. The period from 15^(th) to 19^(th) century was characterized by a rapid reducing accumulation and concentrations of volatile compounds suffering post-depositional loss linked to sparse precipitation amount,which was temporally consistent with the Little Ice Age(LIA) episode. Comparison between observed accumulation rates with other eastern Antarctic ice cores show a consistent decreasing trend during LIA, while sea salt and dust-originated ions increased due to sea ice extent and intensified atmospheric transportation. Distribution of volcanic originated sulfate over the Antarctic continent show a significant change during the 15^(th) century, coincident with the onset of the LIA. These results are important for the assessment of Antarctic continent mass balance and associated interpretation of the Dome A deep ice core records. | ChuanJin Li JiaWen Ren CunDe Xiao MingHu Ding AiHong Xie ZhiHeng Du XiangYu Ma DaHe Qin | 2019 | Research in Cold and Arid Regions2019，11，1： | 1 |
| 18 | Spatial distribution of marine chemicals along a transect from Zhongshan Station to the Grove Mountain area, Eastern Antarctica显示文摘This study investigates the regional distribution of marine aerosol originated species(Na+, Cl-, nss-SO42- and MSA) in the snow pits(or firn cores) collected along a transect between Zhongshan Station and the Grove Mountain area(450 km inland) on the eastern side of the Lambert Glacier Basin. Concentrations of Na+ and Cl- decrease exponentially with distance from the coast to 100 km inland(i.e., 1500 m a.s.l.). Statistical results demonstrate that distance from the coast inland and elevation affect the concentration of sea-salt originated ions in inland areas significantly. Increase of Cl-/Na+ ratio and higher variability in its standard deviation suggest that there are other sources of ions in addition to sea-salt in inland areas of the Antarctic continent. The concentrations of Na+ and Cl- from nine sampling sites in the Grove Mountain area are relatively higher than those from sites along CHINARE transect, although all sites are at similar distance inland. This phenomenon indicates that the barrier effect of the mountain may be the most important factor influencing ion deposition. In addition, nss-SO42- and MSA vary differently, with nss-SO42- decreasing with distance more significantly. This implies that sources and transporting pathways influence the deposition of the two sulfur compounds considerably, being supported by the spatial pattern of correlation coefficients between the nss-SO42- and MSA. | QIN Xiang LI ChuanJin XIAO CunDe HOU ShuGui DING MingHu REN JiaWen QIN DaHe | 2014 | Science China Earth Sciences2014，57，10： | 1 |
