Use satellite imagery to count Weddell Seals in Antarctica

Logo for Use satellite imagery to count Weddell Seals in Antarctica
Knowing ‘how many’ of any species is a challenge for researchers. In recent years satellites have been used, but there are so many pictures, we are asking classrooms to help.

This is an opportunity for students to use satallite imagery to count populations of wild animals. In this case, Weddell Seals in Antarctica.  New images will be uploaded every season so classrooms can continue this project on a long term basis.
