December 4 2017

This was a normal release, mostly containing bug fixes after the exceptional PostgreSQL release in November. Some small features were released. Our major projects are on-going.

Instruments

  • Underwater Listening Station (ULS) data acquisition for AMAR hydrophones

  • Design and progress on the Pump Control and Valve System (PVCS) for the ferries

Earthquake Early Warning

  • Modify DMAS/Oceans2.0 Driver and Remote Shore Station instances to support data communication bandwidth below 38 kbit/second (both transmitted and received), this allows EEW stations to run on satellite internet only
  • Modify DMAS/Oceans2.0 Driver and Remote Shore Station instances to optimize memory CPU usage to run on the Fitlet mini-computers
  • Bug fixes on the EEW algorithms

DFO Fisheries Stock Reporting System

  • Completed full edit support for all reference table data
  • Customized Liferay user screens to work for Fisheries users

NOAA Cruise (SeaTube V2)

  • Completed a prototype version of SeaTube to be used by NOAA (internal testing only at this stage)

Data Products and Preview

  • Data Preview Summary tabs now show the deployments under each device

November 9 2017

This release was a major infrastructure update to Oceans 2.0: the system was migrated from using an Oracle database to a PostgreSQL database.

Instruments

  • Updated CORK Parser to parse ASCII Mode Data

  • Implemented SCU-V2 Data Acquisition, Control, and Monitoring
  • Back End work for Memorial Buoy Data Acquisition
  • LBNL Borehole Seismometer FTP job Created
  • WERA FTP Jobs created

Automated Testing

  • Continued progress on automated DAF testing, task/job automated testing and reprocessing/parsing testing

Earthquake Early Warning

  • Architecture for correlator/associator and notification is in progress
  • Continuing testing and improvements to EEW data acquisition

Web

  • The data search page now has a filter column on the side, the user can filter on instrument depth by selecting a depth from and depth to from a set range. they can also enter a time range to filter the device tree by instruments that were deployed in that time range. lastly the device tree now has a visibility filter so what is in the tree reflects what is visible within the current google map bounds.

Infrastructure

  • Completed the migration of the metadata database from Oracle to PostgreSQL. Users will notice some speed improvements on Oceans 2.0 pages and overall performance is more consistent. The new database has more capacity to be expanded and upgraded as we are no longer tied to the UVic Oracle site license. As such, licensing of Oceans 2.0 is now much easier as standalone licenses of Oracle are expensive, while PostgreSQL is open source / free. 

DFO and NOAA projects

  • Several new DFO and NOAA related projects are in progress, standby for new features related to this work.

Data Products and Services

  • New data product: Time Series Thomson Detided. This is applies to pressure sensors on Bottom Pressure Recorders (BPRs). It applies a specific tide-removing algorithm to make the data more reliable for tsunami detection and for input into tsunami models. The algorithm was supplied by Richard Thomson, Alexander Rabinovich, Isaac Fine and Tania Lado Insua and makes use of Rich Pawlowicz's T_TIDE toolbox.
  • Data restrictions have now been applied to all webservices. Continuing work on a UI to manage data restrictions, attributions, etc.

Dive Logging

  • Added several Save options when creating a dive observation:
    • Save & Exit - the original Save feature. Returns you to the dive log page.
    • Save & Refresh Time - saves the observation, stays on the Observation page, and updates the timestamp. Used when you want to make new observations often.
    • Save & Keep Time - saves the observation, stays on the Observation page, but keeps the same timestamp as the observation you just saved. Used when you want to make multiple different observations that refer to the same point in the video.
  • Separated dive log tags and quick entries by organization. At the time that a new cruise is defined (now renamed to "expedition"), you define which organization the cruise is for. The choices for observation quick entries and tags is different for all dives assigned to that expedition, depending on the organization selected. At the moment we support two organizations - ONC and NOAA.
  • When creating and editing dive log tags and quick entries, these functions have now been separated into separate UI pages under the SeaScribe menu.

Search Hydrophone Data

  • Implemented data access agreements, similar to what was added a few months ago to Data Search.
    • Access agreements are controlled by the Data Product Permissions tab in User Management
    • Access to hydrophone data can be embargoed for a certain date range, or its access can be delayed until it is older than a certain value that can be defined.
  • Added a choice of displaying spectrograms produced from WAV files or FFT files (depending on the type of hydrophone).
  • Added the ability to specify a date range to view spectrograms. They are still displayed one day at a time but if you use the Next and Previous features it will automatically skip over dates that have no data.
  • Added a number of annotation-related features:
    • Ability to display the number of hydrophone annotations that apply to each spectrogram time period, with a hyperlink to open a table to view those annotations
    • Ability to view all the hydrophone annotations for the currently displayed day.
    • Ability to filter the annotations being viewed to show only those containing a specified text string.
    • Ability to export the displayed annotations to a CSV file.
    • Ability to search a range of dates and only show spectrograms that have been annotated with a specified text string (this filters the spectrograms and other data, as opposed to the feature above that only filters the table of annotations).

Miscellaneous

  • On the Device Details page, main tab, a link has been added called Instrument Point People Group. It lists who from each department is responsible for that instrument.
  • State of the Environment plots are now updated automatically using a recurring scheduled job.

  • Continued development of methods to search for data programmatically, including methods to discover where data of a certain type exists if you are not already familiar with ONC's instruments and their locations. This feature is still under development.

 

 

3 January 2017

Data Search

  • Improved the visibility of "Min/Max + Avg" plots to make it more obvious where the average points are.
  • Created scalar profile plots for casts of vertical profilers.
  • Created  a tabular data product for hydrophones based on spectral probability density percentiles.
  • Created data products for the Nortek Signature 55 current profiler.
  • Created cast data products for the PSF instruments (Pacific Salmon Foundation or Salish Sea Marine Survival Project) for raw and corrected data versus depth.
  • The CSV data product now supports company logos and acknowledgement where data agreements exist.

Instruments and Parsers

  • Modified the data parser for the Nanometrics Titan accelerometer used for Earthquake Early Warning to add two additional "derived" sensors for diagnostic purposes. These sensors will give an indication of how close an earthquake came to exceeding the detection threshold, both for the P-wave and the S-wave, to help us tune the detection thresholds.
  • Wrote a parser for the EV Nautilus navigation data.
  • Wrote a driver and parser for the Hemisphere GNSS V104S GPS compass used on the B.C. ferries.

Hydrophone Viewer ("Search Hydrophone Data")

  • Added the option to view FFT-generated spectrograms (called "Broadband Spectrogram" in the Plot drop-down list) where they exist (does not apply to all makes of hydrophones).
  • Added the option to view SPD (spectral probability density) spectrograms although they will not be available until later.
  • Improved the annotation feature on this page so that a table of annotations that apply to a given spectrogram can be displayed if there is more than one. The list can then be filtered by specifying a text string to filter on, and the table can be exported to a CSV file.

Miscellaneous

  • Added deep links to the Data Monitoring tool (in Device Console) so that results can be shared.
  • On the Camera page, the Presets section was removed as cameras can now be controlled using SeaScript.
  • Improved the Data Product Permissions tab in User Management to better support the administration of data access permissions. For example if the list of access rules is large, it will automatically paginate which greatly improves the speed of opening a large group.
  • Started development of the Kalman Filter algorithm for Earthquake Early Warning. This filter and other code will allow us to use data from GPS sensors that will be installed on the land sites in order to improve our earthquake magnitude estimates.
  • Continued development of methods to search for data programmatically, including methods to discover where data of a certain type exists if you are not already familiar with ONC's instruments and their locations. This feature is still under development.

ONC Website (oceannetworks.ca)

  • Developed a mini website for the ISSMMTC conference (8th International Symposium on Submarine Mass Movements and Their Consequences). See http://igcp640.oceannetworks.ca/
  • Modified many of the Community Observatory pages to make them all consistent in appearance, including:
    • Shorter introduction with a "Show More" link added
    • Consistent Latest Readings variables.
    • Consistent titles on data plots
    • A photo album to look through photos rather than placing them all on the page at the same time.
    • Added an Instrument Health section header with content to be filled in later.
  • Did a complete overhaul of the structure of the Installations section of the website, which has been renamed to Observatories. Highlights include:
    • New landing page called Expeditions. Content will be added soon, but for now it gives access to sub pages including Wiring the Abyss.
    • Installations sub–heading has been renamed to Notices.
    • The number of Observatories has been reduced by grouping everything under Arctic, Atlantic, Pacific, and Mobile Platforms.
