CANAPE Recovery Cruise in Beaufort sea

Seven subsurface oceanographic moorings were deployed in the Beaufort Sea north of Alaska for the Canada Basin Acoustic Propagation Experiment (CANAPE 2016). The experiment combines measurements of acoustic propagation and ambient noise with the use of an ocean acoustic tomography array to help characterize the oceanographic variability throughout the year in the central Beaufort Sea. The tomographic array has six Teledyne Webb Research (TWR) swept-frequency sources that incorporate Distributed Vertical Line Array (DVLA) acoustic receiving systems with 15 Hydrophone Modules at 9-m spacing. In addition, all of the TWR source transmissions are being recorded by a stand-alone Distributed Vertical Line Array (DVLA) with 60 Hydrophone Modules at 9-m spacing to study deep-water propagation under the ice.
