The Aanderaa Optode 4531A (S/N 2061) was deployed on 2025-09-12 at Chatham Sound. Chatham Sound is a sound on the North Coast of British Columbia, located between Dundas and Stephens Islands and the Tsimpsean Peninsula near Prince Rupert. This device is a Oxygen Sensor. Oxygen sensors measure dissolved oxygen concentration in seawater. 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 Aanderaa Optode 4531A (S/N 2061) a été déployé le 2025-09-12 au Chatham Sound. Chatham Sound est un son situé sur la côte nord de la Colombie-Britannique, entre les îles Dundas et Stephens et la Tsimpsean Peninsula, près de Prince Rupert. Cet instrument est un Capteur d'Oxygène. Les capteurs d'oxygène mesurent la concentration d'oxygène dissous dans l'eau de mer. 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. oceans 1 -130.43114 -130.43114 54.25858 54.25858 2025-09-12T21:38:00Z 29.0 29.0 Geodesy Subcommittee of International Oil and Gas Producers' Geomatics Committee EPSG::5831 Geodetic Parameter Dataset Instantaneous Water Level Depth fractional_saturation_of_oxygen_in_sea_water sea_water_temperature volume_fraction_of_oxygen_in_sea_water saturation_fractionnelle_en_oxygène_de_l’eau_de_mer température_de_l’eau_de_mer fraction_volumique_d’oxygène_dans_l’eau_de_mer CF Standard Name Table 2019-09-19 Version 47 Oxygen Oxygène Global Ocean Observing System Essential Ocean Variables https://goosocean.org/index.php?option=com_oe&task=viewDocumentRecord&docID=17473 Subsurface temperature Température sous la surface Global Ocean Observing System Essential Ocean Variables https://goosocean.org/index.php?option=com_oe&task=viewDocumentRecord&docID=17467 Oceans Government of Canada Core Subject Thesaurus 2016-10-13 N/A Hecate Strait Marine Gazetteer https://www.marineregions.org/gazetteer.php?p=details&id=18823 None Ocean Networks Canada Data Policy https://www.oceannetworks.ca/data/data-policy/ Ocean Networks Canada Society Research Organization Registry https://ror.org/05gknh003 https://ror.org https://dap.oceannetworks.ca/erddap/tabledap/scalar_1218080.html OPeNDAP ERDDAP Data is delivered via ERDDAP, a data server that gives a standardized way to download subsets of datasets in common file formats.

Measurement based on the ability of selected substances to act as dynamic fluorescence quenchers. The fluorescent indicator is a special platinum porphyrin complex embedded in a gas permeable foil that is exposed to the surrounding water. A black optical isolation coating protects the complex from sunlight and fluorescent particles in the water. This sensing foil is attached to a window providing optical access for the measuring system from inside a watertight titanium housing.The foil is excited by modulated blue light, and the phase of a returned red light is measured. By linearizing and temperature compensating, with an incorporated temperature sensor, the absolute O2 concentration can be determined.
