This Web site will automatically display markers for any Beacon, Drifter or ROV it has received a position from within the last 24-hours. Markers will be updated appoximately every 30-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.

Stations

Show/Hide markers for Stn. Kahe, ALOHA, Kaena, the WHOTS bouy & the Bottom-moored sediment trap(s).

Grid Lines

Show/Hide grid lines. Grid lines will adjust based on zoom level.

Bathymetries

There are two Bathymetry overlays that could be used. The 'Oahu' Bathymetry is a 1.5 deg square around the Island of Oahu with 100m contour intervals. The 'Hawaiian Is.' Bathymetry encompasses all of the main Hawaiian Islands. But only uses 200m contour intervals. The 'Oahu' Bathymetry is best for navigating around Oahu due to it's higher level of magnification.

AVISO SLA, MODIS Chl, Thermal Gradient & GPB Night SST

Once these overlays have been enabled, the left- and right-arrows may be used to scroll through past days. New overlays are created daily. They can be included by selecting 'Reload Overlay Tables' under 'Options'.

Tracks

Allows plotting of user defined Drift tracks. First browse to the location of the track file and click 'UpLoad'. Then select one of the checkboxes. Up to 8 tracks can be displayed.

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, Rockblock, 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

Allow Web site to update the positions of the ship, WHOTS bouy, SeaGlider, ARGOS, Novatech, Rockblock & Xeos Beacon markers. The date & time shown in the top panel indicates when the markers were last updated.

Show Data
