Tracking Mary Lee

Oct 15, 2015 #js #map #opendata #opensource

Mary Lee is a 3,456 pound Great White that is tracked by the OCEARCH team, and often approaches the shores of my hometown Ocean City, MD.

You can view her route over the last three years on ocearch.org, but I wanted to see how she traveled that path, from one ping to the next.

It's also interesting to use Esri's World Ocean Base as a base map to see when she moves into shallow and deep waters, and travels along ocean ridges.

Mary Lee's pings are always available from OCEARCH via a somewhat hidden API.

The code to download, format, and display this data is open source.
