- NATO’s scientific ocean research uses drifting buoys equipped with SPOT Trace trackers to study marine currents
- Using the Internet of Things (IoT) to better understand surface drift and dispersion patterns provides valuable information for environmental research, industry, and defence operations
- SPOT Trace was selected for its low cost and reliable, ubiquitous reach
Globalstar Europe Satellite Services Ltd., announced today that scientists from the NATO’s Science and Technology Organisation (NATO STO) are deploying an IoT solution using SPOT Trace™ and Globalstar satellite communications to further their understanding of the world’s oceans.
Research teams from the NATO STO Centre for Maritime Research and Experimentation (CMRE), based in La Spezia, Italy, are embedding low-cost SPOT Trace devices in freely drifting buoys and setting them afloat in the Mediterranean and in Arctic waters to monitor surface drift behaviour. SPOT Trace tracks the movement of these ‘drifters’ and transmits their position data over Globalstar’s Low-Earth Orbit (LEO) satellite network.
The CMRE carries out oceanography and ocean acoustics studies as part of innovative and field-tested Science & Technology (S&T) solutions to address defence and security needs of the NATO Alliance. The data is helping CMRE to measure and understand sea currents with the aim of gaining a deeper understanding of the changing sea environment and to inform NATO operational planning.
The research examines horizontal motion in the sea and how surface properties are transported deeper into the water column. This will lead to a greater understanding of changes in maritime characterisations such as temperature change, acoustic propagation, and the movement of biogeochemical properties (e.g. phytoplankton) and pollutants such as plastic.
With a requirement to track large quantities of drifters, SPOT Trace’s low device cost and affordable data charges were key factors in NATO’s procurement decision. Buoys are fitted with a tiny (7×5 cm) SPOT Trace device which includes an integrated GPS receiver, simplex transponder and motion sensor. Thanks to Globalstar’s fast-moving LEO spacecraft and SPOT Trace’s long battery life, research teams benefit from high frequency sampling, up to every five minutes, and more precise, granular tracking than has been possible with other solutions.
NATO STO CMRE is conducting several studies in parallel. One, sponsored by the US Office of Naval Research, is using SPOT Trace-equipped drifters to conduct oceanographic studies in the Alboran Sea in the Mediterranean, between the Iberian Peninsula and North Africa.
In addition, CMRE’s own studies of drift movement in the seas of the Arctic will see buoys deployed in the Barents Sea, and further into Arctic waters, in Summer 2019.
“The maritime areas in the High North are the new frontier for oceanographic study and more research is crucial. In particular, with polar ice decreasing, we need to understand how Arctic ocean life will be impacted,” said Dr Pierre-Marie Poulain, Principal Scientist and Project Leader at CMRE. Furthermore, Arctic research becomes fundamental to guarantee safe and secure maritime traffic in the new routes around the North Pole.
“It is yet another endorsement of SPOT Trace’s flexibility and reliability that NATO chose Globalstar technology to help support its oceanographic research,” commented Gary King, SPOT Regional Sales Manager EMEA at Globalstar.
“Our changing environment is affecting all kinds of activity on the seas, and we are glad that Globalstar’s combination of state-of-the-art satellite communications and economical prices are helping achieve the goal of better scientific understanding.”
