Collaborative Research: Observing Integrating Ocean Variables

提供资金用于开发一种新的仪器，该仪器将海底压力（Pb），海底到海面声学旅行时间（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）的测量结合到一个独立的设备中。目标是改进HEM，并将该传感器与Pb和IES的传感器结合到一个仪器中，该仪器坚固耐用，易于部署和恢复，寿命长，价格低廉，适合广泛的社区使用。拟议的仪器将提供对海流场和水的性质（例如，温度、盐度、比容异常）。尽管这些仪器是自主的，可以在任何地方单独或阵列部署，但它们也将为计划中的海底电缆海洋观测站的安装做好电缆准备。

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.
