Help using the Pick lists on subset list page

Picking from the drop-down menus: examples

Using 'AND' to combine multiple selections
Using 'OR' to combine multiple selections and projections
Using the string operators
Combining string and numeric operators
Combining string and numeric selections together with projections

Select all values at stations numbered greater than 1 AND (indicated by the comma)
at depths equal to or less than 100 meters deep. The subset list to use is:: sta > 1, depth <= 100

First, pull down the list of variables under 'Selections:' and click on 'sta'.
Then, at the next pull-down list, choose the operator '>'
Next, type the value '1' in the area following the '>'
Finally, push the 'Add selection' button.
Continue, by adding the 'depth <= 100' selection, making certain
on this second selection that the 'AND' combination value is selected,
Then click 'Add selection'.
Double check that the subset list as displayed near the top of the screen is exactly what you want.

Having completed your entry of a new subset list, click on the link 'Continue using new subset list' at the bottom of the page. This will allow you to Plot or Map or Join, etc. with only those values of interest to you.

Select all data from stations numbered 1 OR 2 OR 3, and only view values for station, depth and temperature,
(the vertical bar "|" indicates OR) The subset list to use is:: sta = 1 | sta = 2 | sta = 3, sta, depth, temp; spaces above are presented to improve readability and do NOT exist in the command

Pick list technique

First, pull down the list of variables under 'Selections:' and click on 'sta'.
Then, at the next pull-down list, choose the operator '='
Next, type the value '1' in the area following the '='
Finally, push the 'Add selection' button.
Pull down list and click on 'sta' (again)
Choose operator '=' (again)
Type in '2'
Now, you must choose the value 'OR' for combining with existing, active selections
then click 'Add selection'.
Repeat for 'sta = 3'
Moving to the right-hand column to perform the projections:
Click on 'sta', then click on 'depth' and 'temp' in the list of variables presented
Note: depending on your browser, you may need to hold the Shift key
or the Control key to choose multiple entries from a list.
Finally, click on 'Add projection(s)'.
Double check that the subset list as displayed near the top of the screen is exactly what you want.

Select all stations that have a "N" in the station identifier (given that the data contains a station identifier comprised of letters as well as numbers). The subset list to use is:: station contains N

Pick list technique

First, pull down the list of variables under 'Selections:' and click on 'station'.
Then, at the next pull-down list, choose the operator, 'contains'
Next, moving across the screen to the right, type the value 'N' in the available space
Finally, push the 'Add selection' button.
Double check that the subset list as displayed near the top of the screen is exactly what you want.

Select all values on cruises beginning with "AL" and only from deep water. The subset list to use is:: cruise_id begins_with AL,depth>1000

Pick list technique

First, pull down the list of variables under 'Selections:' and click on 'cruise_id'.
Then, at the next pull-down list, choose the operator, 'begins_with'
Next, moving across the screen to the right, type the value 'AL' in the available space
Then, push the 'Add selection' button.
Returning to the same are of the screen, Pull down the list of variables, and click on 'depth'
Then, at the next pull-down list, choose the operator, '>'
Next, type the value '1000' in the available space
Make certain on this second selection that the 'AND' combination value is selected
Then click 'Add selection'.
Double check that the subset list as displayed near the top of the screen is exactly what you want.

Select only latitude, longitude, date, pressure, temperature and salinity values on cruises beginning with 'TN' and only from the upper water column. The subset list to use is:: cruise_id begins_with TN,press<300,lat,lon,date,press,temp,sal

Pick list technique

First, pull down the list of variables under 'Selections:' and click on 'cruise_id'.
Then, at the next pull-down list, choose the operator, 'begins_with'
Next, moving across the screen to the right, type the value 'TN' in the available space
Then, push the 'Add selection' button.
Returning to the same area of the screen, Pull down the list of variables, and click on 'press'
Then, at the next pull-down list, choose the operator, '<'
Next, type the value '300' in the available space
Make certain on this second selection that the 'AND' combination value is selected
Then click 'Add selection'.
Moving to the right-hand column to perform the projections:
Click on 'lat', then click on 'lon','date','press','temp','sal' in the list of variables presented
Note: depending on your browser, you may need to hold the Shift key
or the Control key to choose multiple entries from a list.
Finally, click on 'Add projection(s)'.
Double check that the subset list as displayed near the top of the screen is exactly what you want.
