PROVIDING CRITICAL INFORMATION ABOUT STATE OF INSTRUMENTS IN REAL TIME AT OVER 4’000 METERS DEPTH WITH LUMA WIRELESS OPTICAL COMMUNICATION NODES.

Germany’s oceanographic research institutes successfully used Hydromea’s LUMA 250LP wireless nodes in depths down to over 4000m. The scientists of the Alfred Wegener Institute (AWI)/Max Planck Institute for Marine Microbiology (MPI) on board the research vessel Sonne were examining the possible environmental impact of deep sea mining of polymetallic nodules in the Clarion Clipperton Fracture Zone (CCZ) in the Eastern Pacific.

​

By fitting their in-situ modules as well as the ROV KIEL6000 (GEOMAR) with Hydromea’s LUMA wireless nodes they were able to directly communicate with instruments at over 4000m depth to ensure that their delicate sensors on board are working properly and to reconfigure the measuring program if necessary. The modems performed flawlessly over a series of 15 dives.

​

Frank Wenzhöfer, principal investigator for in situ flux studies on the cruise SO268-2, said:

 

“This offers a high amount of flexibility and provides significant capacities to work in these demanding environments.”

 

Hydromea’s through-water wireless optical nodes LUMA provide for high-speed and high-bandwidth near-field communication. LUMA offers affordable, portable and low-power high-speed wireless access to the subsea infrastructure down to 6000m depth.

Founded in 2014, Hydromea is a Swiss-based deep-tech company delivering solutions that allow customers to have unparalleled access to the subsea data. Ultra-fast and high-volume real-time data transfer and harvesting bring a paradigm shift in our quest to explore the ocean and understand its impact on subsea economy.
