Waveglider Tracker USM ocean acidification research

Project Description

University of Southern Mississippi (USM) is partnering with ocean engineers at Liquid Robotics, an ocean data services provider credited with developing the world’s first wave-powered, autonomous marine robot called the Wave Glider.

The Liquid Robotics Wave Glider used for the pilot project is equipped with sensors to measure carbon dioxide (CO2) and dissolved oxygen levels, pH, water temperature, conductivity, air temperature, barometric pressure, and wind speed and direction. The carbon dioxide sensor, which measures the mole fraction of CO2 on either side of the air-sea interface, was developed by the Monterey Bay Aquarium Research Institute.

How to

Note - Click the marker to see the sensor data. A popup window will show the uppermost marker's info.
- To see a different layer's info, please turn off the uppermost layer and leave a checkmark on the specific data set.
- Click the timer button to show a time slider in the bottom. To see all data, expand the slider from beginning to the end.

Default time slider shows 1-day range.

Thumb index can be expanded like below.

** time slider moves every 3 seconds and loop automatically.

Layer Information


lat/long: WGS84
distance over ground (m): the distance travelled over ground since the last RobotTelemetryReport.
heading skew (∆˚): the difference between the true direction travelled over the ground and the direction of thrust.
heading sub (˚): the direction of thrust (usually the heading of the submerged part of the waveglider)
temp sub (˚C): water temperature measured in the submerged glider unit. water speed (knots): water speed.


Dissolved Oxygen (ml/l): amount of oxygen dissolved in the water.
Oxygen Solubility (ml/l): volume of oxygen gas at starndard temperature and pressure conditions (STP) absorbed from humidity-saturated air ata total pressure of one atomosphere, per unit volume of the liquid at the temperature of measurement


wind speed in Knots
air pressure in milibar
air temperature in ˚C
