Collaborative Research: Observing Integrating Ocean Variables

该项目为开发一种新型仪器提供了资金，该仪器将测量海底压力（Pb）、海底到海面的声波传播时间（来自反向回声测深仪（IES））和运动感应电场（来自水平静电计（HEM））整合到一个独立的设备中。目标是改进HEM，并将这种传感器与Pb和IES传感器结合成一种坚固耐用、易于部署和回收、寿命长、价格低廉、适合广泛社区使用的仪器。拟议的仪器将只使用海底仪器，对水流场最严重的垂直结构和水柱的水性质（如温度、盐度、比体积异常）提供长期的深海观测。尽管该仪器是自主的，可以在任何地方部署，无论是单独部署还是阵列部署，但它也将为可能安装在计划中的海底电缆海洋观测站做好准备。

Funding is provided for the development a new instrument that combines the measurement of bottom pressure (Pb), sea floor to sea surface acoustic travel time (from Inverted Echo Sounder, IES), and motionally-induced electric fields (from Horizontal Electrometer, HEM) into a single autonomous device. The goal is to improve the HEM, and incorporate this sensor with ones for Pb and IES into an instrument that is robust, easily deployed and recovered, long-lived, inexpensive, and suitable for wide community usage. The proposed instrument will provide long-duration, deep-ocean observations of the gravest vertical structure of current fields and water properties (e.g., temperature, salinity, specific volume anomaly) of the water column using solely seafloor instruments. Although autonomous and deployable anywhere, either singly or in arrays, the instrumentation will also be cable ready for possible installation on planned undersea cabled ocean observatories.
