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.

为开发一种新仪器提供资金，该仪器结合了底部压力 (Pb)、海底到海面声波传播时间（来自倒置回声测深仪，IES）和运动感应电场（来自水平静电计，HEM）的测量到单个自主设备中。我们的目标是改进 HEM，并将该传感器与 Pb 和 IES 传感器结合到一个坚固、易于部署和恢复、寿命长、价格便宜且适合广泛社区使用的仪器中。拟议的仪器将仅使用海底仪器对当前场最严重的垂直结构和水柱的水特性（例如温度、盐度、比容异常）进行长期、深海观测。尽管这些仪器是自主的并且可以在任何地方单独或成组部署，但这些仪器也将做好电缆准备，以便可能安装在计划的海底电缆海洋观测站上。
