The oceanographic campaign GLISTEN ‘15, on going off Elba Island (Italy), is testing new sensors and solutions for ocean characterisation using underwater gliders.

From 26 August to 9 September 2015, the NATO Research Vessel Alliance will be conducting the oceanographic campaign GLISTEN ‘15, in the Tyrrhenian Sea, north of Elba Island. The trial will be preceded by five days of engineering tests (from 17 to 21 August).

Scientists from the NATO STO Centre for Maritime Research and Experimentation (CMRE) and their partners from nine institutions of five NATO Nations (Canada, Italy, Norway, United Stated and United Kingdom) will collect acoustic, oceanographic and geophysical data using both traditional and novel observation methods, such as underwater gliders, the greenest unmanned underwater robotic platforms that are available to date. In particular, GLISTEN ‘15 aims to test the readiness and feasibility of the novel payloads and smart sensing methodologies, which CMRE has developed to enhance current capabilities for ocean environment characterisation. GLISTEN is one of the sea going efforts of the CMRE EKOE (Environmental Knowledge and Operational Effectiveness) programme that develops scientific and technical solutions to the ocean environment predictions for NATO Nations and Navies. “A deeper knowledge of this area could be also beneficial to the local communities for a more effective protection of the marine environment”, underlines Yong-Min Jiang, CMRE
GLISTEN ‘15 Scientist in Charge. “The final data will be made available to the scientific community under request”.

CMRE fleet of seven gliders will be deployed to study the properties of the seabed, water column and sea surface. The research will also include seabed characterisation using naturally occurring ambient noise that is generated by the sea surface waves. Thanks to the hydrophone and hydrophone array equipped gliders, which have no propulsion and are able to operate silently, scientists shall be able to obtain the seabed types and layer structures by listening and then analysing the ambient noise in the ocean.
