Using 'AND' to combine multiple selections

You want to:

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

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.


Using 'OR' to combine multiple selections and projections

You want to:

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

Using the string operators

You want to:

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

Combining string and numeric operators

You want to:

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

Combining string and numeric selections, together with projections.

You want to:

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
