Barkley Canyon Head Current Meter Deployed 2017-06-15 | Barkley Canyon Head Courantometre déployé 2017-06-15
Listed in ONC (Ocean Networks Canada)
abstract: English = The Nortek Aquadopp Current Meter A3L5380 AQD8375 was deployed on 2017-06-15 at Barkley Canyon Head.
Description
Barkley Canyon Head is located within Barkley Canyon, where benthic processes and sediment dynamics are observed. This device is a Current Meter.
Acoustic Current Meters (ACM) measure current speed and direction, using the Doppler Effect. Aquadopp current meters 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 3.0 digital infrastructure, with quality assurance and derived data products following established practices., abstract: French = Ce Nortek Aquadopp Current Meter A3L5380 AQD8375 a été déployé le 2017-06-15 au Barkley Canyon Head.
Barkley Canyon Head est située dans Barkley Canyon, où les processus benthiques et la dynamique des sédiments sont observés. Cet instrument est un Courantometre. Les courantometres acoustiques (ACM) mesurent la vitesse et la direction du courant à l'aide de l'effet Doppler.
L'instrument transmet une courte impulsion sonore, puis écoute son écho pour mesurer le changement de hauteur ou de fréquence. Le changement de fréquence peut déterminer la vitesse du courant. Il a été deployé sur une plateforme fixe.
Les données de ce déploiement sont archivées et accessibles sur l’infrastructure numérique Oceans 3.0 du Réseau Canadien des Océans (ONC), avec assurance de la qualité et produits dérivés selon les conventions établies.
