Antarctic Killer Whale Track Map (2016)

  • The season for satellite tagging of killer whales got underway in early 2016.  As of early August, we had tracked a whale that made two migrations to lower latitudes before finally losing communication with the tag (an impressive 5+ months of tracking data for this animal).
  • We deployed satellite tags on two killer whales, but only one tag routinely transmitted good location data.
  • The satellite tag on a killer whale deployed in the Antarctic Sound on February 23rd transmitted data until early August.  The data show the whale's migration (2x) toward lower latitudes and then a return to higher latitudes.  These rapid migrations to subtropical waters have been described by Durban and Pitman, 2012.  Antarctic killer whales make rapid, round-trip movements to subtropical waters: evidence for physiological maintenance migrations? Biology Letters 8:274-277; DOI: 10.1098/rsbl.2011.0875 (see more discussion of this topic and a link to the manuscript on this page).
  • Tracking data will automatically update daily so you can follow the whale (new tracking data are no longer being received from the tag).
  • There is roughly a 24-hour lag on the display of current whale position data.
  • Note:  This app has been tested with modern browsers (e.g., Chrome, Firefox, Opera, Internet Explorer 11) and appears to perform well.
    • The app does not display properly when using Internet Explorer 11 with Compatibility View.
