| 1 | Physical structure and vertical distribution of chlorophyll a in winter sea ice from the northwestern Weddell Sea, Antarctica显示文摘The investigation on sea-ice biology in combination with physics, chemistry and ecology was carried out in the northwestern Weddell Sea, Antarctica, during the cruise ANT/XX III-7 on board POLARSTERN in the austral winter (August-October) in 2006. The distribution of chlorophyll a was measured and related to sea ice texture. The mean concentrations of chlorophyll a in the sea ice varied considerably with ice texture. The concentration of chlorophyll a per core ranged from 2.10– 84.40 μg/dm 3 with a mean of 16.56 μg/dm 3 . And the value of R (chlorophyll a / gross chlorophyll) ranged from 0.79–0.83. These high winter chlorophyll values indicate that primary production is considerable and confirms that there is significant primary production in Antarctic sea ice during winter. Thus this constitutes a major proportion of southern ocean primary production and carbon flux before the sea ice retreats. | DAI Fangfang WANG Zipan YAN Xiaojun LI Zhijun ALLHUSEN Erika DIECKMANN Gerhard | 2010 | Acta Oceanologica Sinica2010，29，3： | 2 |
| 2 | 南极冬季威德尔海海冰物理结构与叶绿素a垂直分布特征显示文摘2006年8—10月极星号ANT/XXIII-7航次,对南极威德尔海西北海域浮冰区进行海冰综合考察,采用海冰物理学、海冰化学和海冰生态学等多学科现场同步观测取样与分析研究新方法。结果显示,测区21个冰站不同冰龄和不同结构类型的海冰冰芯,叶绿素a含量总平均值为16.56μg/dm^3,范围为2.10~84.40μg/dm^3,叶绿素a相对总量的R值均值为0.79~0.83。冰体叶绿素a含量与分布取决于海冰冰晶物理结构及其所处冰层部位,并和海冰生成环境、冰体发育和成冰过程密切相关。研究结果证实南极冬季海冰叶绿素a含量普遍处于较高水平,海冰冰藻具有较强活性,由此表明从整体上南极冬季海冰具有较高初级生产能力。这对正确分析估算冬季南极海洋生物生产,重新评估南大洋碳通量及其在全球气候变化中的贡献,具有重要科学意义。 | 戴芳芳 王自磐 李志军 E ALLHUSEN G DIECKMANN | 2008 | 海洋学报2008，30，4： | 2 |
| 3 | Upper limits for chlorophyll a changes with brine volume in sea ice during the austral spring in the Weddell Sea,Antarctica显示文摘During the winter and spring of 2006, we investigated the sea ice physics and marine biology in the northwest Weddell Sea, Antarctica aboard R/V Polarstern. We determined the texture of each ice core and 71 ice crystal thin sections from 27 ice cores. We analyzed 393 ice cores, their temperatures, 348 block density and salinity samples,and 311 chlorophyll a(Chl a) and phaeophytin samples along the cruise route during the investigation. Based on the vertical distributions of 302 groups of data for the ice porosity and Chl a content in the ice at the same position, we obtained new evidence that ice physical parameters influence the Chl a content in ice. We collected snow and ice thickness data, and established the effects of the snow and ice thickness on the Chl a blooms under the ice, as well as the relationships between the activity of ice algae cells and the brine volume in ice according to the principle of environmental control of the ecological balance. We determined the upper limits for Chl a in the brine volume of granular and columnar ice in the Antarctica, thereby demonstrating the effects of ice crystals on brine drainage, and the contributions of the physical properties of sea ice to Chl a blooms near the ice bottom and on the ice-water interface in the austral spring. Moreover, we found that the physical properties of sea ice affect ice algae and they are key control elements that modulate marine phytoplankton blooms in the ice-covered waters around Antarctica. | LI Zhijun LI Runling WANG Zipan HAAS Christian DIECKMANN Gerhard | 2016 | Acta Oceanologica Sinica2016，35，2： | 2 |
