海洋有机地球化学
海洋氧亏损（低氧）的生消机制及其对碳氮循环的影响和效应
海洋有机碳的通量、示踪和命运

在当前的一段时间内，我在开展海洋和河流、河口环境中（包括北极、南极、赤道海洋；以及不同国家内不同生境的河口近海）有机质性质与成分的研究：通过生物标志物与其他环境参数的分析，揭示有机化合物在海洋、河流中的分布特点，探索有机质的成分变化规律，诠释其背后的控制因素；探索海洋作为有机碳库储存人类排放的过剩二氧化碳的过程中的不确定性，帮助解释当前人类强烈活动背景下全球气候和海洋变化所面临的挑战。
另外，我对水体中的溶解氧也很感兴趣——事实上在我看来这是有机质循环的一部分：有机质在表层经由初级生产产生，这伴随着溶解氧的增加；有机质在底层水的降解，则伴随着溶解氧的亏损。因此，对溶解氧的研究自然就包括其含量、变化特点和控制因素，以及背后的故事。例如，我对长江口外的低氧问题开展了多年的追踪。通过接近10次的船载现场调查，和大量室内仪器分析，我和我的同事们在过去的10年里跟踪了长江口外低氧区的面积和变化规律、并就南北两个区域的氧亏损-有机质降解-营养盐再生的耦合机理差异进行了定量表达。同时，我还在船上进行培养实验，定量现场体系的呼吸耗氧速率，以帮助同事建立低氧模型，为今后预测低氧的发生，乃至低氧的治理提供科学基础。最近两年以来，通过溶解氧同位素技术，我和我的同事发现水柱呼吸和沉积物耗氧对低氧的贡献比例很可能并非一成不变。在低氧发生的时候，水柱呼吸过程（沉降颗粒物的降解）是底层水缺氧的核心推手，海底界面的沉积物耗氧对低氧发生贡献是次要的。于我，这是一个激动人心的定量发现。
在之后的继续研究中，我又把这个假设推广到了潮滩等极浅水体系，发现上述沉积物和水柱耗氧的演替规律仍旧适用。这在氧亏损机制的前进的道路上给予了我新的信心。

基于上述描述，你可以叫我海洋学家或海洋学工作者。用学科的术语来说，我的专业是海洋化学，研究兴趣是溶解氧亏损生消机制及其有机碳循环效应。
