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
Show/Hide markers for Stn. Kahe, ALOHA, Kaena, the WHOTS bouy &

There are five Bathymetry overlays that could be used. The 'Kauai',
'Oahu', 'Maui' and 'Big Island' Bathymetries use 100m contour intervals.
While the 'Hawaiian Islands' Bathymetry uses 200m contour intervals.
The 'Kauai', 'Oahu', 'Maui' and 'Big Island' Bathymetries are best for

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

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

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.
