We measured net planktonic community production (NCP), community respiration (CR), and gross primary
production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...
白令海盆pCO2分布特征及其对北极碳汇的影响

利用中国首次北极科学考察期间所观测到的白令海及楚克奇海表层海水CO2分压(pCO2)的变化及其异常, 研究了白令海盆pCO2的分布特征及与周围水文环流的相关关系. 结果表明, 与具有高生产力的白令海陆架区不同, 在白令海盆观测区内, 叶绿素整体水平较低, 生物作用不是pCO2空间分布的主要调控因子, 而水文环流要素呈现出重要影响, 是典型的高营养盐低叶绿素(HNLC)海区. 研究表明, 白令陆坡流...

We examined the physiological responses of steady-state iron (Fe)-replete and Fe-limited cultures of the biogeochemically critical marine unicellular diazotrophic cyanobacterium Crocosphaera at glacia...
Dynamics of silicon metabolism and silicon isotopic discrimination in a marine diatom as a function of pCO2

2014/5/14
Opal accumulation rates in sediments have been used as a proxy for carbon flux, but there is poor understanding of the factors that regulate the Si quota of diatoms. Natural variation in silicon isoto...
In situ pCO2 and O2 measurements in a lake during turnover and stratification: Observations and modeling
