What is it?
Data Search provides 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. Documentation on data products is here: Data Products Home.
Using a shopping cart model, you can create and download multiple searches at your convenience. If you log in with an Oceans 3.0 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., home).
If you are interested in large amounts of data, you can first sample and explore subsets via Data Search, then automate your big downloads via ONC's Application Programming Interface.
