Due to a software deployment today, some data services may be affected.
The VENUS CODAR high-frequency radar system, which measures ocean currents in the Strait of Georgia, is returning reduced amounts of data at the moment. Frequently, no current vectors are being returned at all.
This appears to be the result of low salinity in the surface waters in the Strait, which in turn is the result of the high flow rates out of the Fraser River during the spring freshet. High-frequency radar waves travel best over highly conductive (salty) water; the effective range of high-frequency radar systems is greatly reduced over fresh water.
The range of radials from the Coal Terminal CODAR station appears to be reduced, particularly towards the north. The effect on the Iona CODAR station, though, appears to be much more dramatic. This is perhaps because the Iona CODAR antenna looks out not onto open water as the Coal Terminal antenna does, but onto mudflats that are exposed during much of the tidal cycle.
This is the first year of operation of the complete CODAR system, so it is unclear how long this situation will prevail. The system was first made operational in early August of last year. Although there will undoubtedly be variations in the freshet and its effects on the VENUS CODAR system from year to year, presumably the system will return to full functionality by August, and hopefully before then.
The Meteorological Station on BC Ferries Queen of Alberni (Vancouver – Nanaimo (Duke Point) route) stopped logging data on 2013-Apr-29 22:43:23 UTC. We are currently investigating the problem.
Update 2013-May-10
The Meteorological Station was restored on 2013-May-07, data are flowing again.
The VENUS team will be at sea between April 28 – May 7 for another maintenance and installation cruise.
Live Data applets on the homepage, video streams and data plots will not update regularly during this time. Some data may be unavailable from the VENUS Download Data page.
The team plans to:
- Recover and redeploy instrument systems in Saanich Inlet.
- Re-install the Delta Dynamics Laboratory platform in Strait of Georgia at 110m.
- Add the Seismic Liquefaction In-situ Penetrometer (SLIP) to the Delta Dynamics study area.
- Install new sensors and systems developed by ONCCEE at the Delta Dynamics and Strait of Georgia East study areas.
- Re-install the DFO’s Institute of Ocean Sciences Hydrophone array at Strait of Georgia East 170m.
- Deploy the Bottom Boundary Layer experiment in the Strait of Georgia Central 300m study area.
Due to the number of platforms being deployed during this cruise, it will take the ONC Data team more time to update all the data services on the VENUS website.

DMAS’ File archiving processes failed between November 10 – 12 2012. Some of our data plots were not updating and data were not accessible from the Download Data page. No data were lost and data have caught up today. All data access tools are currently functioning as expected.
The DMAS team are having issues with their file archiving processes and servers. There was a major failure early this morning and as a result our live data applet on the homepage is showing data lagging significantly, our Data Plots are not updating and data can’t be requested from the Download Data page. Raw Files from October 25, 27, 29, 30 2012 have not been archived and scalar data are significantly behind. The Systems team hasn’t confirmed whether or not these data have been lost or if it resides in the buffer.
Data Access from NEPTUNE Canada are also affected by this failure. Please see http://www.neptunecanada.ca/ for updates.
UPDATE: 2012-11-01
Most of the DMAS issues that occurred yesterday have been resolved. Data have caught up, no data were lost, our data plots are updating and data are available for request for our Download Data page. Raw files are still getting ingested into the database, so data from our complex devices (ADCP, ZAP, Nortek) from October 25, 27, 29, 30, 31 and November first are still unavailable.
Yesterday’s DMAS code release caused the file archiving processes to fail last night. No data have been lost, but yesterday’s (October 25 2012) data are not available from most VENUS instruments. They are actively working on solving the problem.
Due to electrical upgrades at the Saanich Inlet shore station, there will be a ~20 minute down time starting about 13:00 PDT on October 18, 2012.
BC Ferries’ Queen of Alberni is currently docked for maintenance from Oct 10 – November 2012. There will be no data from the SeaKeeper Ferry system during that time.
UPDATE—Nov 22, 2012: Ferry data is back online and plots are updating.
UPDATE—Nov 9, 2012: The Queen of Alberni is not yet operational. We will update the post when it is.
The DMAS server is unstable today, which means you will see menu loading problems on the Download Data page, live data might now be displayed on our home page and some of our plots might not be updating. Our Systems team is working hard to resolve the issue.
The Institute of Ocean Sciences (IOS – Saanich Inlet Shore Station) will be doing emergency generator testing tomorrow (Tuesday October 2) morning at 10:00 PDT. Data flow may be interrupted briefly during this time.
Data stopped flowing in from the SeaBird 16+ CTD 7128 (deployed in Saanich Inlet at 103m, site DCF-13) on 2012-Sep-24 at 04:03:09 UTC. Data from the Aanderaa Optode 0793 at the same site also stopped flowing at this time (since it is piggybacked on the SeaBird CTD). We are currently trying to diagnose the problem and will post an update shortly.
Update: the SeaBird 16+ 7128 was shut down on October 16, 2012 due to malfunction.
There will be a brief DMAS outage today for a code deployment starting at 11am. The Download Data page and Live Data Applets may be unavailable during this time.
The VENUS Strait of Georgia instruments are unavailable until further notice. On Aug. 1 2012, the array suffered a major power failure just before a scheduled maintenance cruise. We recovered node pods for inspection and discovered a fault on the main power connector to the Central node pod. As part of the connector assembly remains on the seafloor attached to the backbone cable, it appears that the repair will entail a lift of both node bases and part of the cable. We have removed all instruments from the seafloor and are planning the repair. We will post the plans when we have more information. We were able to move several experiments to Saanich Inlet. CODAR data from Strait of Georgia remain available.
UPDATE
The Feb 2013 maintenance cruise restored many instruments to Strait of Georgia East and Strait of Georgia Central. See this article to find out what was and was not done.
The VENUS maintenance cruise is complete! We are working hard to bring all our data products back online. New devices may appear on our Download Data page, but requests for their data may fail. Thank you for your patience.
UPDATE: All known issues have been fixed.
A software change has resulted in some broken features on the VENUS website. We are working to restore these features as quickly as possible.
So far the following features are scheduled to be fixed:

We’ve been experiencing some interference between hydrophones 1 and 2 at Strait of Georgia East Node; there is a bug in the processing hardware that manifests itself as crosstalk in hydrophone 1 when the automatic gain control is on for hydrophone 2. We could turn off the gain control, but then we effectively lose 20 dB of dynamic range.
If you see a similar plot, this is not a failure of the HighTech hydrophone, but interference from hydrophone 2 when the automatic gain control is on.
