Progressed with the development of the tsunami-detection section of the WARN (Web-enabled Awareness Research Network) project. Added the following derived sensors to record the output from several tsunami detectors:
- Direct Detider Weighted Threshold changes state if the detided pressure ("DART Pressure Residual") value exceeds a threshold.
- Signal to Noise Ratio (using the STA/LTA algorithm) - outputs the ratio of the short term average to the long term average of the detided pressure.
- Signal to Noise Ratio Weighted Threshold - changes state if the Signal to Noise Ratio exceeds a threshold.
- WARN Kertosis - outputs the result of the Kertosis statistical analysis algorithm.
In addition the WARN Threshold Watcher derived sensor amalgamates the outputs from all the tsunami detectors. All of these derived sensors have been added only to the following bottom pressure recorders (BPRs):
- 22790 Folger Deep
- 21301 Cascadia Basin (CORK)
- 22503 Clayoquot Slope

- Added two new scheduled jobs (157 and 158) to run specified data searches on a regular basis. These can be used to produce, for example, daily plots for the same instrument. Plots like this will be added to the ONC website soon.
- Changed Plotting Utility to make the default plot "Clean Min/Max+Avg" rather than a "raw" plot that includes data that is probably not valid.
- Modified the DeviceAttributesService to return Nortek attributes within a specified time range.
- Added ancillary tilt data to Satlantic Radiometers data products and improved how the data products work with Satlantic's analysis software Prosoft.
- "Derived sensors" are pseudo sensors whose values are derived mathematically from other sensors, typically on the same device. The data products and metadata for derived sensors was changed to include QAQC (data quality) flags inherited from their parent sensors.
- We are now storing quarter scalar data in the Cassandra database in addition to what was already being stored. At this time the Oracle database remains the primary database. A switch to Cassandra is forthcoming, but in the meantime it is possible for users to be added to the "Cassandra Group" in User Management. This will cause all plots made by Plotting Utility to use data from Cassandra.
- Added a parser for IC Listen hydrophones.
- Improved the performance of the QuarterScalarDataSummary job.
