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.

为开发一种新的仪器提供了资金，该仪器将海底压力(Pb)、海底到海面的声波旅行时间(从反向回声测深仪(IES))和动感电场(从水平静电计(HEM))结合在一个单独的自动装置中。我们的目标是改进HEM，并将该传感器与用于铅和IES的传感器整合到一种坚固耐用、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中。拟议的仪器将仅使用海底仪器对电流场的最严重垂直结构和水柱的水性质(如温度、盐度、比容异常)进行长期的深海观测。虽然该仪器是自主的，可以单独或以阵列形式部署在任何地方，但也将为可能安装在计划中的海底电缆海洋观测站做好电缆准备。
