New Map Sets Framework for Describing Ocean Ecology in Unprecedented Detail

As a follow on to a comprehensiveĀ global Ecological Land Units map that Esri and the USGS released in December 2014, a new global Ecological Marine Units (EMU) map will be available in the coming months. To better understand the significance of the new global EMU map and the data behind it, I recently met with Dr. Dawn Wright, Esriā€™s chief scientist, to find out more about why this map was created and how it will be used.

Ecological Marine Units map?

The project is a new undertaking of Esri in collaboration with Dr. Roger Sayre of the USGS, the Marine Conservation Institute, NatureServe, the University of Auckland, GRID-Arendal, NOAA, Duke University, the Woods Hole Oceanographic Institution, and many other partners.
