Greenlandic vessel Sanna back in the water ready for habitat mapping this summer Published 27.03.2018

Acoustic Equipment on Sanna – GreenWave

Advanced acoustic mapping techniques open the door for new collaboration opportunities with scientific and non-scientific communities. Technological progress in this area is crucial to maintaining international standards for fish stock estimation, ensuring a sustainable source of income for Greenland and providing new knowledge and a better understanding of the marine Arctic—from microscopic animals, pelagic fish stocks and large marine mammals, to underwater geological structures and landforms.

The project provides a technological platform for surveying pelagic and benthic environments in Greenland to better understand their functioning and variability in an ice-influenced environment. The acoustic systems are composed of a SeaBat T-50R ‘Extended Range’multi-beam echo sounder for high-resolution seabed mapping and a Simrad EK80 ‘fish’ echo sounder for penetrating pelagic ecosystems.

The planned research activities meet the requirements and standards of several leading organizations.
