| 摘 要： | 首次通过2008-2009年在西北地中海和东地中海海域投放的两台Bio-Argo浮标的观测数据,分析与研究了该海区黄色物质次表层极大值的季节变化规律.研究表明次表层黄色物质在夏季开始爆发,伴随着叶绿素a浓度的逐渐降低；到冬季在强烈的垂向混合作用下结束.且黄色物质极大值的深度与叶绿素a浓度极大值(DCM)的深度基本一致,说明虽然黄色物质与浮游植物之间并不存在直接联系,但浮游植物的降解是黄色物质的主要来源.文中推测,可能由于该海区浮游植物与微生物的强耦合,导致了黄色物质与叶绿素a之间存在明显的反变关系. |

| Abstract: | Based on the in situ dataset observed by two Bio-Argo floats deployed in the northwestern and eastern basins of Mediterranean Sea in 2008-2009, this study focuses on the seasonal variations of colored dissolved organic matter (CDOM) subsurface maximum. The research results show that the subsurface CDOM bloom started in summer accompanied by gradual decreasing of chlorophyll-a concentration, and disappeared in winter owing to deep mixing effect. In addition, the depth of subsurface CDOM maximum was always following the depth of deep chlorophyll-a maximum (DCM) during the CDOM bloom period, which suggests that the source of oceanic CDOM is almost certainly the result of phytoplankton degradation, although chlorophyll and CDOM are not correlated directly. It is assumed that a probable strong coupling between phytoplankton and bacteria leads to the obvious contravariance observed between CDOM and chlorophyll-a. |
