Ecology and Physiology of Sea-Ice Brine Microalgae

存在于南极洲麦克默多湾陆地固定海冰内的盐水池中的鞭毛微藻将被调查。重点研究了优势囊泡形成盐水微藻的生长和生活史。海洋学家设想，盐水微藻囊可能是过去全球气候的重要古环境指标。Stoecker博士计划进行实地和实验室实验，以评估鞭毛微藻的生理生长反应和囊肿形成对温度、盐度、无机营养物和光照变化的影响。还将在每年的海冰下的水柱和沉积物中评估来自海冰的盐水微藻囊肿的存在。该研究将为研究固陆冰和海底沉积物中盐水微藻的相互作用提供重要的生物学信息。＊＊＊

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. ***
