The images displayed in the tabs are snapshots of the monitor that checks the status of the dataloggers installed at USArray Transportable Array stations. You can choose from the following views:

• Multi column view – a streamlined multi-column view where only a few parameters are displayed, but more stations fit into a smaller image.
• Single column view – all parameters are displayed with one station per row.
• Icon view – just the station name with only the up/down status and eight critical parameters displayed.

The page is auto-refreshed every 120 seconds to reflect the latest datalogger status.

The station code (on the left-hand side) is in the format NN_STA where NN is the network (such as Transportable Array, TA), STA is the station code.

To understand the various colors read the descriptions in the table to the right and to understand the various codes read the below.
