mg冰球突破项目
The sea surface microlayer (SML) is the key interface between the oceans and the atmosphere. 这是大气气体进入海洋的地方, 大气颗粒沉积的地方, 生物活动的副产物聚集在哪里, 污染物集中的地方(e.g. microplastics), where radioactive particles deposit and where oil slicks reside.
尽管它很重要, 它的物理和化学性质仍然知之甚少,因为很难精确地探测和取样. Its thickness is ill-defined with reported figures ranging from tens of nm to mm; its viscosity, 导电率, 化学成分, 生物组成几乎是未知的. Even sampling the SML is challenging, let alone monitoring the composition continuously. 因此,迫切需要开发新的物理方法和仪器来探测SML.
该项目建议开发可单独寻址的微电极阵列,以在空气-海水界面进行现场测量. 这些微电极将用于执行:
- 安培测量(e.g. to assess the local concentration of heavy metals or dissolved oxygen)
- 测量阻抗以确定局部电导率
- 电位测量(e.g. 以探测当地的pH值)
