Peter Sigray

Peter Sigray is a researcher at the Royal Institute of Technology (KTH) in Stockholm, Sweden. In his earlier work, he studied electromagnetic phenomena in the oceans. He especially utilized the “Motional Induced Voltage” technique using trans-Atlantic telecommunication cables to explore the inflow of the North Atlantic Current between Faroese and Iceland. He later turned his interest to bioacoustics, studying different aspects of the marine soundscape. He was part of the BIAS project, the first worldwide attempt to make a large-scale assessment of the marine soundscape. He has developed several novel instruments, for example, the particle motion sensor and the electromagnetic sled (SEMLA). The former measures the acoustics using the same concept as a fish's ear, and the latter maps electromagnetic fields generated by submarine cables. The SEMLA was used extensively in collaboration with the University of Rhode Island. Lately, he has been involved in underwater communication applications for AUV applications.

Currently, he is appointed Chair of the European expert group “Technical Group of Underwater Noise” (TG Noise), which supports the European Commission in implementing Descriptor 11 of the Marine Strategy Framework Directive. 

The latest appointment is as Director of the Swedish Maritime Robotic Laboratory at KTH (SMaRC2.0), which will start in 2024.
