研究方向

1. 流域、河口与邻近海域的生物地球化学过程;
2. 河口与近海入海物质及其生态环境效应。

关键科学问题

1. 陆海相互作用背景下,化学物质随河口、近海动力学的迁移、转化规律;
2. 气候变化和人类活动等多重压力下,我国近海典型生态系统的结构、功能响应及其机制;
3. 不同时间尺度下,自然气候变化和人类活动在近海环境演变中的生物地化记录的定量甄别。

近期科研进展:

1. 生物地球化学过程及其生态环境效应:

长江口夏季(25, 000km2)河流输入、大气沉降和SGD生源要素入海通量百分比

沉积物中埋藏的有机质百分含量和稳定碳同位素对历史事件有较好的响应。比如1855年的黄河改道事件:在1855年之前,E2沉积物(图a)中13C信号具有更大尺度的波动,但在1855年之后,13C的信号显著收窄;与此相对应,E4沉积物(图b)中的13C值一直较为稳定,并和1855年后的E2沉积物信号相吻合。

惰性有机质的分布特征:在河口区域随着入海过程发生陆源惰性有机质的稀释(即减少);随着现场生产贡献有机质的增加,惰性有机质(肽聚糖)的含量有随之发生增加,这个贡献估计来自细菌微生物。

全球不同近海海域低氧过程向大气反馈的温室气体CH4和N2O通量(μmol m−2 d−1):长江口缺氧区温室气体排放通量处于全世界的中上水平

2. 新技术的开发和应用:

首次用拉曼光谱来研究珊瑚骨骼中的P/Ca环境参数;且将P/Ca分辨率提高到天的尺度为研究短周期气候突变事件提供技术上的可能。

太湖水华后经细菌改造的难降解的CRAM化合物增加

 

东海、南海北部日本带鱼(Trichiurus japonicus)种群数量演化动态与海面变化关系:末次盛冰期东海种群微弱下降,南海北部种群持续增长;冰消期-全新世,东海种群迅速增长,南海北部种群不断下降。

拖曳式实时表层水采集系统:改进多参数巡航、适用于痕量分析的表层水采集系统。实现海洋化学要素现场监测和实时水样采集,使分析海水中纳摩尔、皮摩尔级别的痕量元素成为可能。
