1.2.2 Querying a Dataset

After a dataset, variable, and region (space and time) are chosen, you can find out roughly how much data (and what kind) you have selected with the Get Details button. Clicking this will send a query to the dataset to find out how much of it fits your chosen ranges; for example, how many images fall within your time range, or how many XBT casts fall within your geographic selection box.

For gridded data, the Get Details button will display a star in the Time window for each grid available. That is, if you are looking at a dataset consisting of a series of complete grids, one per day, you will see a star drawn for each day in the requested time range. If you're looking at a dataset containing non-gridded data, you'll see stars in the geographic and depth windows, too.
