Abstract
A Recording Instrument Package or RIP was a completely self-contained bottom-mounted observatory designed to record digitally, on magnetic tape, the average spectrum of underwater ambient noise once an hour for one year. A recovery system was incorporated which was initiated by a coded acoustic signal sent from the recovery vessel. The RIPs were designed to characterize the seasonal changes in under-ice acoustic ambient noise in channels of the Canadian Arctic Archipelago. This report discusses the electronic and mechanical design and describes the installation and recovery of the units in the Arctic.
