9318772 Stoecker Flagellated microalgae that exist in brine pools within land- fast sea-ice in McMurdo Sound, Antarctica, will be investigated. The research focuses on the growth and life history of the dominant cysts-forming brine microalgae. Oceanographers envisioned that cysts of brine microalgae may be important paleoenvironmental indicators of past global climates. Dr. Stoecker plans both field and laboratory experiments to evaluate the physiological growth responses of flagellated microalgae and cyst formation to changes in temperature, salinity, inorganic nutrients and irradiance. The presence of brine microalgal cysts from sea-ice will also be assessed in the water column and sediments under annual sea-ice. This research will provide significant biological information on the interaction of brine microalgae in land-fast ice and underlying marine sediments. ***

9318772 Stoecker 将研究存在于南极洲麦克默多海峡固定海冰内盐水池中的有鞭毛微藻。 该研究的重点是主要形成囊肿的盐水微藻的生长和生活史。 海洋学家设想，盐水微藻的包囊可能是过去全球气候的重要古环境指标。 Stoecker 博士计划进行现场和实验室实验，以评估有鞭毛的微藻和胞囊形成对温度、盐度、无机营养物和辐照度变化的生理生长反应。 还将评估年度海冰下的水柱和沉积物中是否存在来自海冰的盐水微藻包囊。 这项研究将为陆地固定冰和底层海洋沉积物中的盐水微藻相互作用提供重要的生物学信息。 ***
