Phytoplankton contributes most of the primary production (PP) in the sea, which is the foundation of marine ecosystems. The method of using ¹⁴C as a tracer to measure the PP has played a critical role in the progress of marine research ever since the method was invented in the 1950s. The seamark achievement is that the ocean has been discovered to produce half of the organic carbon in the earth. But the ¹⁴C method is as much blamed as praised. The top criticism is the question “Is the measured ¹⁴C-PP the true PP?” almost everyone in the community would ask. The key of the answer to this question is that photosynthesis is a chain of reactions, not only one simple reaction the chemical equation appears. The measured rates are of different reaction sites depending on the environments and the choice of methodology. We may name them as different “currencies” and use the “exchange rate” to link them together. That is what “anatomy of marine primary production” going to address. I’m going to disassemble the phytoplankton photosynthesis. In addition, the depth-integrated PP needs to be disassembled as well, though the analysis is different.

个人简介

谢聿原的科研生涯从尝试研究藻类二氧化碳浓缩机制CCM开始，研究生期间主要在CHOICE-C航次中用¹⁴C做为tracer测量和研究海洋初级生产力PP，博后期间开始学习一些海色遥感知识，尝试进入新的研究方向。作为一个海洋人，希望自己在未来的道路上能做到两点：（1）了解海洋，分享知识；接下来工作将以光和碳的耦合为主线，结合藻类形态、荧光、海色遥感等要素探讨浮游植物固碳的奥秘。（2）助力保护蓝色海洋的事业；期望能优化生物量和生产力的观测手段，可以更好地监控海洋环境的质量，保护海洋资源。
