Wally Land Current Meter Deployed 2011-09-18

The Hs Engineers Current Meter 2001 (SN 21539) was deployed on 2011-09-18 at Wally Land. Wally Land is a location within Barkley Canyon gas hydrate field, where hydrate dynamics are observed. This device is a Current Meter. Acoustic Current Meters (ACM) measure current speed and direction, using the Doppler Effect. Aquadopp current metres have a sensor head that contains 3 acoustic transducers, a tilt sensor, a temperature sensor and a pressure sensor. The instrument transmits a short pulse of sound, and then listens to its echo to measure the change in pitch or frequency. The change in pitch can determine the velocity of the current. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.
