Ecology and Physiology of Sea-Ice Brine Microalgae

将对南极洲麦克默多湾陆上海冰卤水池中存在的9318772种斯托克鞭毛微藻进行调查。重点研究了优势成囊卤水微藻的生长和生活史。海洋学家设想，卤水微藻的包囊可能是过去全球气候的重要古环境指标。斯托克博士计划进行现场和实验室实验，以评估鞭毛微藻和包囊形成对温度、盐度、无机营养物质和光照变化的生理生长反应。还将在年度海冰下的水柱和沉积物中评估来自海冰的卤水微藻包囊的存在。这项研究将提供有关耐陆冰和底层海洋沉积物中卤水微藻相互作用的重要生物学信息。***

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. ***
