Ship measurements made two days after the passage of a tropical depression (TD) in the South ChinaSea (SCS,April 2011) showed two contrasted responses of the partial pressure of CO2 at sea surface(pCO2,sw).In low sea-surface salinity (SSS) waters,pCO2,sw was low (349 ± 7 μatm),and the areawas a carbon sink (-4.7 ± 1.8 mmol CO2 m-2 d-1),whereas in water with high SSS and chlorophyll a andlow dissolved oxygen and sea surface temperature,pCO2,sw was higher than normal SCS water (376 ±8 vs.362 ± 4 μatm) and the area was a carbon source (1.2 ± 3.1 mmol CO2 m-2 d-1).

浊水溪流域位于台湾岛西部平原,属亚热带季风气候区.因台湾处于板块交界带地形陡峭且地体构造活动频繁,每年受季风豪雨及台风事件侵袭影响,使浊水溪每年平均输沙量达约54 百万公吨.尽管如此,因丰、枯水季沉积物供应率差异大且不稳定、此外浊水溪出海口属于中潮 (平均潮差 2.7m)的海岸环境,使细粒沉积物在出海口处不易保存下来.这些条件使浊水溪出海口虽在地形上具有波控型三角洲状的外形,但却无法在沉积物纪录中

本研究旨在揭示现代长江口不同沉积环境磁性矿物分布的差异,寻找有效识别沉积环境的磁学指标,以便更好地将环境磁学应用于河口古环境研究.利用国家基金委公共航次和国土资源部公益项目在长江口及邻近陆架采集的浅表层沉积物样品,进行粒度和磁性测量.我们将采样区分为汊道、拦门沙、三角洲前缘斜坡、前三角洲、三角洲-陆架过渡区和残留砂区六种沉积环境.
砗磲作为地质时期以来最大的海洋双壳类,广泛分布于亚太地区.由于其有坚硬的文石壳体,即使死亡后仍能长期保存,能够作为长期气候记录和人类污染记录的良好材料.确定砗磲有机质组分对进行古环境研究具有非常重要的意义,无论是利用砗磲壳体重建海表温度,还是研究碳循环或地质事件,都涉及到砗磲壳体中的有机质组分.
