3 February 2015

Data Search and Data Products

• 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.
• Data products now support the 2015 World Magnetic Model.
• Made the initial changes to support a new header format for the CSV data product.

WARN (Web-enabled Awareness Research Network)

...

• Added ERDDAP (OPeNDAP) functionality. ERDDAP (Environmental Research Division's Data Access Program) is a data server that gives you a simple, consistent way to download subsets of scientific datasets in common file formats and make graphs and maps.
• On the oceannetworks.ca website it's under Data & Tools as OPeNDAP Web Services.
• On the dmas.uvic.ca website see OPeNDAP Web Services on the Tools menu.

Data Products

• The "Place" field in the metadata reports now gives the complete hierarchical geographic location whenever possible. This is important now that we have merged all ONC observatories in Oceans 2.0. For example the TEMPO-mini location would appear as "Ocean Networks Canada -> Pacific -> Northeast Pacific Ocean -> Endeavour -> Main Endeavour Field -> TEMPO-mini"
• Made improvements to RDI 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, improved appearance of ADCP plots.

...

• For the first time, you can now search for instruments from all Ocean Networks Canada locations without having to switch networks. The "Network Preference" option on the Tools menu has now been removed.
• For the first time, VENUS data can be searched using Oceans 2.0 software. The VENUS data download site will be maintained for a few months but will eventually disappear.
• In Data Search, some data products are not yet available for the VENUS network. In particular, many complex specialized data products for VENUS instruments are not available. This includes specialized ferry plots, ZAP, Kistler, LISST, CODAR, Imagenex rotary sonars, Nortek Vector & Vectrino. Until they are supported in Data Search, these data products will be available in VENUS data download. We are working to migrate all data products to Data Search.
• This "merging" of all observatories applies to all applicable web pages in Oceans 2.0 including Data Search, Plotting Utility, SeaTube, Cameras, and internal tools such as Device Console, Topology View, etc.
• The list of locations is divided into Arctic, Atlantic, and Pacific.
• NEPTUNE instruments are located under Pacific / Northeast Pacific Ocean.
• VENUS instruments are located under Pacific / Salish Sea
• The Mill Bay observatory, located at Brentwood College, is located under Pacific / Salish Sea / Saanich Inlet / Mill Bay.
• You may notice some minor changes to the header section of some data products and to the metadata reports, but the contents of the data will be the same as before, including when compared with the VENUS data download site.

Data Products

• Adjusted the plots for downward-facing echosounders located on the Inshore Profiling System to orient them correctly.
• Created a new QAQC flag with a value of 6 to indicate that an insufficient number of data samples are available in order to produce a resampling average for this "bucket".
• Created MATLAB and PNG (plot) data products for the ASL AZFP. These are located on VENUS in the Strait of Georgia, and on the Offshore Profiling System at Barkley.

...

• Event Maintenance was added to the Tools menu. This feature allows you to define events that will be logged and will trigger some action. An example of an event is when a sensor reading goes above a defined threshold.
• Added the ability to subscribe to events (all types of events, not just WARN events) so that an e-mail will be sent to you when the event occurs. This is only useful for WARN for test purposes. All e-mails are logged in the Event Subscription Log tab. At this time it is possible to define an event that indicates that a tsunami was detected at any of the WARN tsunami detection instruments. The final piece that will allow you to define an event that will be triggered only after a tsunami has been detected at three locations within a certain time will be added soon. E-mails are "throttled" so that they will not be seen as spam by being sent too often (defaults to once per hour).
• Made significant progress in the development of a prototype iPhone app to warn users of an impending earthquake or tsunami.
• Added the following instruments to the WARN tsunami detection network. This brings the total tsunami detection instruments to 6.The new instruments have the usual 12 WARN derived sensors.
  • BPR (Bottom Pressure Recorded) 10703 at Endeavour (Main Endeavour Field)
  • BPR 22791 at Cascadia Basin
  • CTD (Conductivity Temperature Depth) 23027 at Barkley Upper Slope

Data Products

• All scalar data products now give a QAQC (quality) flag of 6 when resampling is used and there are less than 70% of good samples available in a given resample period. This flag used to be 4 in this case but that may have implied that the data was bad rather than missing.
• Data products (in Data Search) and Plotting Utility no longer show a data gap if less than 70% of the required good data is available in a given resample period, but only for certain devices. Those excluded from the 70% rule include Engineering devices, camera controls, and devices that collect data in bursts rather than at equal intervals such as Tempo-mini.
• MAT, ODV ("TXT"), PNG/PDF data products now update their status every 10 seconds when the data products are being computed. This is more often than before in most cases.
• Added new MAT, PNG/PDF data products for the ASL echosounders: AZFP (Acoustic Zooplankton Fish Profiler) and AWCP (Acoustic Water Column Profiler). Standardized this data product with the existing AWCP MAT files, with various improvements in speed and reliability. Made these new data products are available on both data search and VENUS data download.
• Added backscatter calibration to ASL data products.
• The data products for mobile devices (like ferry instruments, gliders, vertical profilers) now include additional sensor data to give some context to where the data was collected. At the present time this could include things like depth and/or latitude, and longitude. The sensor data is often taken from adjacent instruments and merged to fit the timestamps of the sensor being searched.

Data Products

• Added "pressure VPS" data (ie. pressure from the CTD on the VPS in order to establish depth) to the data products for the SBE63 dissolved oxygen sensor on the VPS (Vertical Profile System).
• Modified all data products for all mobile devices to include whatever mobile position data is available for each reading (latitude, longitude, depth/altitude, pitch, roll, heading). This applies to all mobile devices such as Buoy Profile System (ie. Saanich Inlet Profiler), Vertical Profile System (ie. Barkley Upper Slope Profiler), ferry instruments, gliders, ROVs, ice buoys, etc.
• Improved profile plots and added daily inshore profile plots to the website.
• Initial changes to ADCP plots to make them more consistent across networks. Eg. changed intensity plots from compensated backscatter to RSSI, smarter ranges, removed extra time stamps, etc.
• Implemented standardized spectrogram data products for all hydrophones, enables posting live data to the website (will be brought online mid-september pending military driver changes).
• Implemented a tool to bulk import annotations. This will enable us to import libraries of hydrophone annotations, among other applications.
• Added clean option for quick plots.
• Finalized Kongsberg Rotary sonar data products, including handling of big files, speed and plotting improvements.
