Data Products

Here's the place to learn and talk about our data products - both current and future. The aim of this documentation is to help our users understand and make use of our data products. A secondary purpose is to double as our data product specifications. This documentation is maintained as data products are improved and added. User input for new and improved data products is encouraged: comment below, press the button in Data Search Step 3, or [contact us].

New Features and Highlights

• As part of the merge of VENUS and NEPTUNE data products, we have added or improved the following:
  • Kistler Accelerometer Data (to be made searchable mid August)
  • Sequoia LISST data products
  • Imagenex rotary data products and 81a files
  • CODAR data products
  • Ferry plotting products: time-distance-variable scalar plots and spatial scalar plots
  • Added support for ZAP echosounders to the ASL echosounder data products, which already support AZFP and AWCP echosounders, the data products for which were already standardized across both networks and data portals.
  • Added Nortek raw data products for all Nortek devices. These are the files that would be produced by the Nortek data acquisition software for the 6 types of Nortek sonars.
  • Improvements to ADCP data processing: dynamic rotation of data to external, internal or fixed attitude values, improved documentation (in the wiki and within the MAT files), added linear and discrete bin-mapping to correct for tilt and several other quality of life changes.
  • Improved integration of mobile positioning and attitude data into all scalar data products, including support of ferry data products.
• Added device-level scalar time series plots to support State of Environment plots and the new Data Preview feature (both are coming soon).
• Manufacturer format .RDI files are now corrected for heading/pitch/roll, including rotation of Earth co-ordinate data. Existing post-processed RDI files will need to be regenerated before RDI files will be made search-able.
• New data products for hydrophones: spectral MAT files and spectral probability density plots.
• See the latest release notes here.
• Coming soon: variable by location search, State of Environment plots, Nortek .dep configuration files, improved spectrograms.

  Data Product Options

  For all scalar data products and some complex data products, users will be presented with options to customize their data products. These options are described in the individual data product pages. A compilation of the options is presented in the data product options page.

  Data Quality

  Data quality information is supplied by way of data quality flags and comments in the data products, as well as annotations listed in the metadata reports. See the Quality Assurance Quality Control page for more information.

  Metadata

  Metadata reports available with nearly all different data products. These PDF reports are produced automatically when a data search is completed and are made available via a link adjacent to the data, see step 3 in data search help. The reports contain extensive information about the data, including instrument location, deployment, calibration, data quality and data gaps.

  Mobile Data

  See the mobile device page to see how data products handle data from mobile devices.

  Conventions

  Time-stamps: Time-stamps are always in UTC. For file-names and string dates, the format conforms to the ISO8601 convention: yyyymmddTHHMMSS. In some cases, the millisecond portion may be added: yyyymmddTHHMMSS.FFFZ. Numerical time-stamps within data product files may follow a different format as noted on the data product pages. For instances, numeric time-stamps within MAT files are in the MATLAB serial date format. When [resampling], the time-stamps are generally taken from the the centre of the resample interval.

  File-names: Note that the underscore character, "_", is used to separate the components of the names. It is also used to replace any spaces in the name to maintain compatibility. File breaks are avoided as much as possible, but do occur for many reasons, including configuration or device changes, plus some data products have daily file breaks.

  For an instrument by category search, files are named as DEVICECODE_SENSORNAME_yyyymmddTHHMMSS.FFFZ_yyyymmddTHHMMSS.FFFZ-MODE.EXT where:

  • DEVICECODE is a descriptive string unique to each instrument.
  • SENSORNAME is the sensor name as it appears in data search, and is only included if a single-sensor data product was requested.
  • The first yyyymmddTHHMMSS.FFFZ is the time-stamp (ISO8601 format) of the first data record in the file. The second yyyymmddTHHMMSS.FFFZ is the last time-stamp of data in the file. The date-to time stamp is not mandatory, as files which are streamed directly from the file archive will not get a data-to in their file-names. The time-stamp format optionally includes milliseconds: yyyymmddTHHMMSS.FFFZ, where 'FFF' are the milliseconds. The time span of the data within the file may be considerably less than than the requested search time span. Instrument by category searches are limited to the selected instrument deployment: use the 'All Available' option when selecting the time range to search for all of the data for the selected instrument and deployment.
  • MODE is optional text which allows files of the same extension to be differentiated. It is used for different operation modes (Kongsberg scan or sweep for instance) or different data product options. Data product option mode strings are only used on scalar data products, examples: '-NaN', '-clean', '-NaN_clean_avg15minute', '-MinMax1hour', see here for more details. In addition, the VPS cast products supply the cast time range and direction here.
  • EXT is the file extension.

  For instrument by location and variables by location search types, files are named as STATIONNAME_DEVICECATEGORY_SENSORNAME_yyyymmddTHHMMSS.FFFZ_yyyymmddTHHMMSS.FFFZ-MODE.EXT where

  • STATIONNAME is the station name, including node and station names separated by dashes, for example: BarkleyCanyon-VPSUpperSlope.
  • DEVICECATEGORY is the device category, such as 'CTD'. If there is more than one device in the category, the file will contain multiple devices combined together for a long record of data.
  • SENSORNAME is the sensor name and is omitted for a device-level data product that contains multiple sensors.
  • yyyymmddTHHMMSS.FFFZ, MODE and EXT are as above.
