Cruise & Drifter Tracks

This Web site will automatically display markers for any Beacon, Drifter, AUV or ROV it has received a position from within the last 24-hours. Markers will be updated appoximately every 5-minutes. Selecting the checkboxes for the various Beacons, etc. will display the full drift track.

Clicking a marker with the right mouse button will bring up a menu. Menus are context-sensitive and will depend on the type of Marker.

Markers

Allows plotting of markers at the specified Lat/Lon. If Lat/Lon not specified, the marker will be plotted in the center of the Map space. Once the marker is displayed, use the right mouse-button to control its attributes. You may include a range circle by entering a 'Range' value (in decimal km) and then selecting 'Range' from the mouse menu. You may also move the marker once plotted. Double click to fix the marker.

Labels

Most (ARGOS, NovaTech, Xeos, etc.) markers can include a label. Enter the label into the textbox, then select 'Label' from the marker (right-click) mouse menu. This is a good way to know what type of array is being tracked by a specific beacon.

Tail

Drift Tracks can become unwieldly after a while. For example, a typical SeaGlider deployment lasts 3-months. Specifying a 'Tail' value will only display the last N-days. Enter the desired number of days, then select 'Tail' from the marker (right-click) mouse menu.

Reload Overlay Tables

Auto Update
