TEMPERATURE VARIATIONS AT THE GREAT WALL STATION (1985—2008) AND ZHONGSHAN STATION (1989—2008),ANTARCTIC Bian Lingen, Ma Yongfeng, Lu Changgui and Lu Longhua 2010, 22 (1):  1-9.  DOI: 10.3724/SP.J.1084.2010.00001 Abstract ( 2267 )   PDF (441KB) ( 1708 )   Chinese Antarctic Great Wall Station(GW) and Zhongshan Station(ZS) have been set up for 25 and 20 years respectively. The variations and trends of monthly, seasonal and annual mean air temperature for both stations are presented by surface meteorological observation data. The warming rate of annual mean temperature is 0.27 ℃/10 a and 0.12 ℃/10 a respectively for GW and ZS. The trend of GW is relatively similar with the rate 0.33 ℃/10 a of Bellingshausen station about 3km away from GW. It means that the warm... Related Articles | Metrics

THE STUDIES OF SURFACE MASS BALANCE AND ICE FLOW ON GLACIERS AUSTRELOVéNBREEN AND PEDERSENBREEN,SVALBARD,ARCTIC Xu Mingxing, Yan Ming, Ren Jiawen, Ai Songtao, Kang Jiancheng , E Don 2010, 22 (1):  10-22.  DOI: 10.3724/SP.J.1084.2010.00010 Abstract ( 2234 )   PDF (1951KB) ( 1688 )   The glaciers Austre Lovénbreen and Pedersenbreen are located at Ny-lesund, Svalbard. Based on the observation of first year (2005/2006), surface mass balance and ice flow velocity of both glaciers have been analysed, while the front edge of Austre Lovénbreen has also been surveyed. The results are as following: (1) The net mass balance of Austre Lovénbreen and Pedersenbreen is -0.44 and -0.20 m w.e., respectively. Their annual ablation is -0.99 and -0.94 m w.e., respectively, and corresponding ELA is 478.1... Related Articles | Metrics

DIFFERENCE OF TWO SALINITY PARAMETERIZATION SCHEMES IN SIS SEA ICE MODEL Wang Qingyuan, Li Qingquan, Wang Lanning 2010, 22 (1):  23-32.  DOI: 10.3724/SP.J.1084.2010.00023 Abstract ( 2351 )   PDF (532KB) ( 1584 )   In this study, we mainly introduce two salinity parameterization schemes used in Sea Ice Simulator (SIS): isosaline scheme and salinity profile scheme. Comparing the model equations in isosaline scheme with that in salinity profile scheme, there is one different term between the two schemes named salinity different term. The thermodynamic effect of the salinity difference term on sea ice thickness and sea ice concentration showed that: in the freezing processes from November to next May, the sea ice tempera...

DISTRIBUTION AND REPRODUCTIVE BEHAVIOR OF PENGUINS ON ARDLEY ISLAND AND THEIR ENVIRONMENTAL IMPACT FACTORS Sun Weiping, Cai Minghong, Wang Haiyan, Xing Chuang, Lu Bing, H.U. Peter 2010, 22 (1):  33-41.  DOI: 10.3724/SP.J.1084.2010.00033 Abstract ( 2509 )   PDF (516KB) ( 2032 )   During the period of 2006/07 Antarctic summer, species population, distribution and reproductive behavior of the penguins in the areas of the Great Wall Station were investigated. Five species of the penguin were recorded, Gentoo penguin (P. papua), Adelie penguin (Pygoscelis adeliae), Chinstrap penguin (P. antarctica), King penguin (Aptenodytes patagonicus) and Emperor penguin (A. forsteri). The first three species bred locally, while the other two species were met occasionally. Ardley Island was one of th... Related Articles | Metrics

CLIMATOLOGICAL ANALYSIS FOR THE SYNOPTIC SITUATIONS OF THE FOG AT THE GREAT WALL STATION,ANTARCTIC Xu Cong, Yang Qinghua, Xue Zhenhe 2010, 22 (1):  42-47.  DOI: 10.3724/SP.J.1084.2010.00042 Abstract ( 1888 )   PDF (2033KB) ( 1614 )   Based on the observed data of Great Wall Station and NCEP data from 1985 to 2006, analyzation was made by climatological statistics and synoptic analysis. It is showed that the seasonal variation of the fog was controlled by atmospheric circulation and pressure field. Three typical synoptic patterns of the fog are found, they are the Front-of-A-Depression type, the Saddle-Shaped-Field type and the Passing-Weak-Cyclone type. The Front-of-A-Depression type is the most important synoptic situation. Mostly adve... Related Articles | Metrics

SCREENING AND IDENTIFICATION OF COLD-ACTIVE β-GALACTOSIDASE-PRODUCING BACTERIUM AND CHARACTERIZATION OF THE β-GALACTOSIDASE Zhou Chunlei, Yu Yong, Li Huilong, Zeng Yinxin, Chen Bo 2010, 22 (1):  48-55.  DOI: 10.3724/SP.J.1084.2010.00048 Abstract ( 1995 )   PDF (342KB) ( 1700 )   In this study, 73 β-galactosidase-producing bacterial strains were screened from 322 cold-adopted isolates from the seawater, sea ice and marine sediment samples collected from Chukchi Sea, Canada Basin, Greenland Sea and coastal regions of Chinese Antarctic Zhongshan Station. Strain Bcw006, one of the producers, was further studied. Based on 16S rRNA gene sequence homology, the strain was identified as Alteromonas sp. BCw006. The optimal growth and enzyme production for the strain was at 24℃, pH of 6.0—8.0... Related Articles | Metrics

PROSPECT OF RESEARCH ON ARCTIC BLACK CARBON AEROSOL Zhan Jianqiong, Chen Liqi, Zhang Yuanhui, Yang Xulin, Li Wei 2010, 22 (1):  56-68.  DOI: 10.3724/SP.J.1084.2010.00056 Abstract ( 3146 )   PDF (1172KB) ( 3451 )   Over the past 100 years, the average temperature increasing rate in the Arctic is about twice as the global average temperature increasing rate. Althouth the anthropogenic long-lived greenhouse gases play a predominate role in radiation forces in weather system, the black carbon aerosol and other short-lived pollutants could also explain a significant fraction of the Arctic warming. Therefore, reducing the emission of black carbon aerosol into the atmosphere will cool the planet and make a negative feedback... Related Articles | Metrics

The coupled model was based on the MITgcm ocean circulation model and classical Hibler79 type two category thermodynamics-dynamics sea ice model. The sea ice dynamics was considered based on Viscous-Plastic (VP). The sea ice thermodynamics was considered based on Winton three-layer models. A detailed configuration of coupled model has been introduced. Special attention has been paid to the model grid setup, subgrid paramerization, ic... Related Articles | Metrics
