The Friday Harbor Laboratories Ocean Observatory (FHLOO)
Data are streaming live to the Northwest Association of Networked Ocean Observing Systems’ (NANOOS) Visualization System (NVS) website.
Data are permanently archived and publicly available at the Biological and Chemical Oceanography Data Management Office (BCO-DMO) website.
The FHLOO is stationed off of FHL’s floating dock, ~1-2 meters beneath the surface. It consists of a suite of sensors working in concert to produce live data visualizations of current conditions in the Salish Sea. Read more about the launch of this project and the hopes for its impact in the November 2020 edition of Friday Harbor Labs Tide Bites.
The observatory is equipped with the following instruments:

| Carbon Dioxide (partial pressure) | µatm | Sunburst Sensors SAMI-CO2 |
| Chlorophyll | µg/L | WET Labs ECO FLNTUS |
| Conductivity | S/m | Sea-Bird Electronics 37-SM/SMP |
| Dissolved Oxygen Concentration | mg/L | Aanderaa Optode 4351 |
| Dissolved Oxygen Percent Saturation | % | Aanderaa Optode 4351 |
| pH (total scale) | Sunburst Sensors SAMI-pH | |
| Salinity | PSU | Sea-Bird Electronics 37-SM/SMP |
| Turbidity | NTU | WETLabs ECO FLNTUS |
| Current Velocity | Sontek ADP 250 kHz |
