Plotting Utility
WARN (Web-enabled Awareness Research Network)
- Increased the earthquake detection grid by 50% to detect more distant events. There have been a number of small earthquakes slightly to the northwest of the original grid that would have been excluded had they been large enough to be detected.

- The earthquake data dashboard developed last month is now visible in the Data and Tools page.
WARN (Web-enabled Awareness Research Network)
- Wrote a web service (EventDefinitionService) that an external device can call to initiate an earthquake or tsunami test for demonstration purposes.
- Updated the Nanometrics Titan driver to 1) make it much more sensitive to detecting earthquakes and 2) to start outputting peak displacement (Pd) and predominant period (Tau) continuously for diagnostic purposes.
...
- A new page will be added soon to oceannetworks.ca to display earthquake activity around the world. All events above magnitude 6 are shown, as well as those above magnitude 4 in the southern British Columbia region. The user is able to interact with the map and the table of values. Seismic data collected by our underwater seismometers is displayed for most events. It will probably be added to the Data & Tools section.
WARN (Web-enabled Awareness Research Network)
- Added capability of parsing and archiving the continuous Tau and Pd values coming from the Nanometrics Titan accelerometers for diagnostic purposes, once the on-site driver has been updated.
- Added a new "status" web service to report the status of WARN - ie. the ability to detect earthquakes and tsunamis at this instant (snapshot).
...
- Made improvements to the driver for the RBRduo Temperature Depth Logger for FORCE
- Wrote a driver and parser for the SAMI pH sensor to be deployed at Cambridge Bay
- Now have the ability to acquire and parse navigation data from the Oceanic Explorer ROV
WARN (Web-enabled Awareness Research Network)
- Out of range values for Pd and Tau, the two parameters sent by the accelerometers that are used to compute the epicentre location, are now automatically rejected.
...
- The Wiring the Abyss pages now support multiple simultaneous cruises and dives.
WARN (Web-enabled Awareness Research Network)
- The CAP messages for earthquake and tsunami notification now include a digital signature. The client API verifies that the signature is present and valid before it will act on notifications.
- The API and sample client now display the distance from the user to the epicentre, in km.
...
- Made most features available without having to log in. This can be accessed from oceannetworks.ca via the Video page on Sights & Sounds. The following features still require logging in:
- adding, deleting or editing an annotation
- creating a playlist
- taking snapshots
WARN (Web-enabled Awareness Research Network)
- Created a Java API for users who wish to subscribe to and receive earthquake and/or tsunami notifications on their PC to compute time-to-shaking and shaking intensity.
- Wrote client software that uses the API and displays notifications on a console, as an example of how the API can be used by clients.
- Improved the earthquake notification messages to add the number of sensors that contributed to each detection and notification.
...
- Added a new search feature to Data Search (and Plotting Utility) called "Sort by: Primary Sensor" (currently disabled). This is useful when you want to search for data by property but you aren't sure what instruments measure that property. Or there may be more than one instrument but you don't know which one is the best one to use. To use Sort by: Primary Sensor you first select the location you want, then you select the water (or air) property without being concerned about what instrument is measuring that property. If there is more than one instrument, this feature will automatically select the one that we consider to be the best one to use. The software has been written but this feature will not be enabled until testing is completed.
- For data products for the ZAP (Zooplankton Acoustic Profiler), improved the Config field to show which fields are instrument configuration and which are post process information.
- Hydrophone data products can now make use of NAXYS calibration files.
Plotting Utility
- Added a new feature - "Sort by: Primary Sensor". See Data Search above (currently disabled).
- Developed a new version of Plotting Utility where most features can be accessed without needing to have an account or having to log in. This is linked to the oceannetworks.ca website from the Preview & Download page (under Data & Tools). All the usual features will work except for the following:
- Details, Docs, and Download Data links
- Saving plots
WARN (Web-enabled Awareness Research Network)
- Finished thoroughly testing the Earthquake Correlator and fixing all issues that were found.
...
- Modified the way data can be manually flagged as good or bad - what we call the "manual QA/QC process". The process is now simpler and more foolproof in that if you need to change the flags on data that already has QA/QC flags, you merely have to state what new flags you want and what time ranges they apply to. You don't have to concern yourself about the state of existing flags when creating your manual QA/QC file.
- It is now possible to flag data as bad as soon as the data is received - ie. automatically. This is useful if it is known that the instrument is not performing correctly.
WARN (Web-enabled Awareness Research Network)
- Completed the web service support for CANARIE. This was the final piece to complete the NEP-105 CANARIE-supported project (however additional WARN development is taking place under a new project). The web service confirms to CANARIE that WARN is operational and reports the number of earthquakes and tsunamis reported in the past 24 hours. It also provides CANARIE with links to documentation on the project.
- Implemented a server "push" notification method to notify external clients of earthquakes and tsunamis. Later an example client application will be developed to demonstrate how this system works, and to provide a template for users who wish to develop their own client application.
...
- It is now possible to select an instrument for searching data by clicking on it on the Data Search map or in the usual way using the search tree.
- Modified the metadata reports to show the full path for hyperlinks so this information would not be lost if the report was printed.
- Removed the Network Topology "Sort by" option from Data Search.
- Made the initial changes to support a new header format for the CSV data product.
- Improvements for Nortek ADCP data products: more information within the .mat file products on what was done to the data, improved handling of mobile data, particularly headings and rotations.
WARN (Web-enabled Awareness Research Network)
- Added a web service so that CANARIE can confirm that WARN is operational.
- Completed most of the work for the earthquake detection correlator.
