Turtle Apache Tags
Welcome to the Explorer
When the viewer is opened for the first time, all of the published records in the database are displayed on the map, as well as in the table below the map. The default map is a “satellite” view; this can be changed to a “map” view to make it easier to identify geographic locations.
The lines on the map are colour-coded by species. Solid lines represent female turtles; dashed lines males.
To identify a single turtle of interest represented in the map, zoom in until the line on the map is clearly visible, then carefully hover (mouse over) the line, until the hand changes to a pointed figure. Clicking once will display a small window containing basic details of that particular turtle, which will also be highlighted in YELLOW in the table below (scroll down, if necessary).
Note: If a record has been entered in the system, but does not appear in the map, this probably means that it is awaiting verification prior to publication.
For easier viewing, the map can be enlarged (and the table compressed) by using the appropriate toggle that appears above the map (upper right hand side). Similarly, the map can be closed to give a better view of the table, by selecting the appropriate toggle. The results of any table can be printed to a PDF file by selecting the print command.
The left-hand side menu uses a novel “faceted search” to list the entire database contents, organised into about a dozen categories. Alongside each sub-category, a numerical value indicates how many records in the database contain that particular attribute. Clicking on any given sub-category in succession progressively filters the data to reveal only the records of interest. The current search categories are displayed at the top of the menu. For example, one may wish to display:
- Green turtles of the Western Indian Ocean (WIO) that were tagged in Comoros and retrieved in Tanzania.
- Loggerhead turtles tagged in South Africa between 2000 and 2014 and retrieved in Madagascar.
- All juvenile green turtles that were foraging when originally tagged.
- To de-select any item, simply click on the X that appears to the left of the title. Allow a few moments for the screen to refresh between each operation.
The table below the map shows only basic information associated with a given turtle: Country of origin and retrieval; year of tagging and retrieval; species; gender and life stage (at retrieval). To view the comprehensive record for any turtle, registered users (only) may click on the VIEW link in the right-hand column of the table.
For more tips on navigating the EXPLORER, please consult the HELP icon in the upper right-hand corner of the screen.
Use the pan and controls embedded in the map to move around the map and to zoom in and out.
