Geodetic Parameter Dataset
The EPSG Geodetic Parameter Dataset is a structured dataset of Coordinate Reference Systems and Coordinate Transformations, accessible through this online registry (www.epsg-registry.org) or, as downloadable zip files, through IOGP's EPSG home page at www.epsg.org. The geographic coverage of the data is worldwide, but it is stressed that the dataset does not and cannot record all possible geodetic parameters in use around the world.

Oceans 3.0
Oceans 3.0 is Ocean Networks Canada's data management and repository system.
The Nortek Aquadopp Current Meter A2L5379 AQD8389 was deployed on 2017-11-03 at Boundary Pass. Boundary Pass is a strait located along the boundary between Washington State and British Columbia. It connects Haro Strait with the Strait of Georgia. 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.
Ce Nortek Aquadopp Current Meter A2L5379 AQD8389 a été déployé le 2017-11-03 au Boundary Pass. Boundary Pass est un détroit situé le long de la frontière entre l'État de Washington et la Colombie-Britannique. Il relie le Haro Strait au Strait of Georgia. 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.
