What is it?
Data Search provides researchers with robust data processing and visualization for both scalar and complex data products. Results with accompanying metadata reports can be published in scientific papers. Many more instrument types are searchable than in Data Preview, including hydrophones, sonars, vertical profilers, ship data and cameras.
Using a shopping cart model, you can create & download multiple searches at your convenience. If you log in with an Oceans 2.0 account, your previous data searches are retained.
Why is this useful?
Searching massive data sets over time can generate huge data downloads. Data Search gives you options such as averaging, Min/Max and selecting Clean or Raw data to control the amount of data you wish to process for downloading.
A search history lets you start a search while at one location (e.g., work) and then check in on that search from somewhere else (e.g., you mobile device, or at home)

How to use Data Search
Step 1: When you first open Data Search, the list and map display all data source locations in the Ocean Networks Canada archive.
Choose Instruments by Location, Instruments by Category, or Properties (measurements) by Location. (click to enlarge)
Step 2: Use the filters.
The filter panel at right lets you refine the list of Instruments and Measurements by filtering for Depth, Time Period, and Property.
Click the blue triangle to hide and show the filter panel.
Step 3a: Choose an Instrument or Property from the list.
After you make a selection, a dark grey box lists all Devices (instruments) that have measured your Property of interest at that Location. Click the red Select This Data Source button to continue.
Step 3b: Choose an Instrument or Property from the map.
You can also zoom the map and click icons on the map to select instruments. After selecting an Instrument or Property, click the red Select This Data Source button to continue.
Click on Step 2: select data product. The screen displays a listing of devices historically deployed, a graph of data availability, data product formats, and delivery options.
Click on Step 3: view cart. A list of three carts is displayed: open, in progress, and completed. Review your search parameters, and when you're satisfied click 'Checkout All'.
At any point you can review your search cart. In this example, an executing search is highlighted for deletion. This can be done before, during or after searches are executed. Nothing is downloaded to your computer at this time.
After your search has completed, you can download the result and open with a zip compression program that supports 64-bit file fornat.
