PacX Sensor Specifications

The following sensors are installed on all four Wave Gliders. The default sampling interval for all sensors is 10 minutes.

Sensor Model Description

Airmar PB200 Weather Station

The PB200 uses 4 ultrasonic transducers to accurately and instantaneously measure air temperature, barometric pressure, wind speed, wind gust speed, and wind direction one meter above the deck of the Wave Glider.

The internal WAAS/EGNOS GPS engine and three-axis solid-state compass make it possible for the PB200 to provide navigation data, magnetic variation and both Apparent and True Wind Speed and Direction without the need to add additional sensors. Airmar’s unique motion correction software provides unparalleled heading accuracy (to within 2° under dynamic conditions).

Datawell MOSE-G GPS-based Directional Wave Sensor

This sensor measures significant wave height, average period, peak period, and peak direction. Measuring wavemotions in three directions, the unit gives out the real time heave (in periods between 1.6 and 30 seconds), north and west displacements as well as common wave parameters like Hs and Tz and spectral data, and is accurate to 0.5% after calibration.

Turner Designs C3 Submersible Fluorometer

This sensor measures chlorophyll-A and crude and refined (poly and monoaromatic hydrocarbons) oil fluorescence, as well as turbidity and water temperature just below the float of the Wave Glider. The fluorometer is designed to incorporate up to three optical sensors ranging from the deep ultraviolet to the infrared spectrum.

Seabird GPCTD + DO

This Glider Payload sensor measures water Conductivity, Temperature, Depth (pressure), and dissolved oxygen, and is located on the base of the float. The sensor supports 4 different sampling profiles:

Continuous Sampling - The pump runs continuously, and the CTD samples once every 1, 2, 3, or 4 cycles. This produces a time series suitable for application of high-quality finish corrections for dynamic errors observed in the data.

Fast Interval Sampling - When the interval between samples is 5 to 14 seconds, the pump runs continuously and measurements are made at the chosen interval, allowing users to conserve power by reducing the sample rate.

Slow Interval Sampling - When the interval is 15 to 3600 seconds, the pump runs for 11.3 seconds before each CTD measurement, plus 2.1 seconds during the measurement. Then the CTD turns off the pump and goes into a low-power state until the next measurement. Dissolved oxygen is not measured in this mode. Dissolved oxygen measuring is not supported in this mode.

Spot Sampling - Single measurements and transmission can be commanded for testing, diagnostic, vehicle-control, or situational awareness purposes.
