The study provides one of the first lines of evidence showing linkages between Antarctic phytoplankton abundance and composition in response to ENSO,based on historical reconstruction of sediment biomarkers.In addition to sediment biomarkers,field measured and remote sensing data of phytoplankton abundance were also recorded from Prydz Bay,Eastern Antarctica.Community structure of field measured phytoplankton showed significant El Nino/La Nina-related succession during 1990 to 2002.

Since the 1980s,anthropogenic activities have led to problems such as an increase in agricultural drainage and sewage effluent,causing excess nutrient enrichment and subsequent severe environmental pr
2013年9月在长江口锋面区布放水质浮标系统,获得了20 多天表层磷酸盐、溶解氧、叶绿素、温度和盐度等参数的高时间分辨率数据,并于投放和回收该系统期间在浮标位臵进行相应参数的连续站剖面调查.

夏季长江口低氧与地形(包括陆架宽度)、台湾暖流深层水的上涌、长江冲淡水扩散导致的层化、营养盐供应及有机质的输运等因素有关,但以往的观测局限于各个因素的综合定性分析,从物理、化学、生物耦合的角度,探讨长江口底层缺氧的形成机制,尚没有深入的报道.本文根据2009年8月和2013年7月夏季航次的pH、DO、DIC、营养盐等水化学参数的结果,发现长江口外夏季低氧区的典型位臵通常与表层的高叶绿素和高生物量的

生物标志物作为一种地球化学指标,在重建过去的海洋环境和生态中已有广泛的应用.但是生标含量与环境因子的关系、表层海水中生标与浮游植物生物量及生产力之间的定量关系仍不明确,制约了应用生标准确重建浮游植物生产力和群落结构变化.本文通过对2011年春夏季东黄海表层悬浮颗粒物中生物标志物菜子甾醇、甲藻甾醇、长链烯酮的测定,来估算在表层水体中硅藻、甲藻和颗石藻的量及相对比例的变化.
