The goals of the CANAPE project include 1 understanding the impacts of changing sea ice and oceanographic conditions on acoustic propagation and fluctuations 2 characterizing the depth dependence and temporal variability of the ambient noise field and 3 measuring the spatial and temporal variability in the upper ocean throughout the annual cycle by combining acoustic and other data with ocean models. Acoustic transmissions are being used to both study acoustic propagation andscattering and help characterize the large-scale oceanographic structure in the Beaufort Gyre. To achieve these goals, the CANAPE project includes a year-long 20162017 CANAPE experiment.This study consists of a year-long experiment in the Canada Basin of the Arctic Ocean during 2016-2017, preceded by a short pilot study during July-August 2015. The goal of the study is to understand the effects of changing Arctic conditions on low-frequency, deep-water acoustic propagation and on the low-frequency ambient noise field. WHOI was responsible for the design and fabrication of the moorings, cruise logistics and directing the deployment and recovery operations at sea.
