Recording Microstructure System

The RMS is a self-contained instrument designed to measure scalar turbulence microstructure. Temperature and conductivity are sampled rapidly with, respectively, two FP07 fast-response thermistors and one SBE7 two-needle electrode conductivity sensor. The RMS can be mounted, e.g., on a CTD rosette frame. The micro sensors are oriented down and are located near the bottom of the frame, so that the flow to the sensors is not affected by the frame structure. The RMS samples the micro sensors and a high-resolution pressure transducer at 512 samples per second. Data are recorded on a solid state hard drive inside the instrument. The rapid sample rate plus the fast-response design of the sensors allows the RMS to measure temperature and conductivity on very small vertical scales.

The RMS can be connected to the external power supplies or to an independent alkaline battery pack, which provides 120 h of operation time.
