This ocean science technology development project will develop a fiber-optic index of refraction sensor for ocean microstructure research. The sensor offers improved resolution of the density gradient spectrum of oceanic turbulence over present sensors and will enhance studies involving our understanding and modeling of global oceanic circulation. The project builds on previous work that modified an immunoassay fiber-optic technology to develop a laboratory prototype refractometer, which will be modified and tested as an ocean-deployable sensor. This sensor has the potential to be thirty times more sensitive than previous sensors designed for oceanic microstructure research. If successful, resulting measurements will contribute to a better understanding of ocean mixing.

本海洋科学技术开发项目将开发用于海洋微结构研究的光纤折射率传感器。该传感器提供了比现有传感器更高的海洋湍流密度梯度谱分辨率，并将加强涉及我们对全球海洋环流的理解和建模的研究。该项目建立在先前工作的基础上，改进了免疫分析光纤技术，开发了一个实验室原型折射仪，该折射仪将作为海洋可部署传感器进行改进和测试。这种传感器的灵敏度可能比以前为海洋微结构研究设计的传感器高30倍。如果成功，测量结果将有助于更好地了解海洋混合。
