Ecological Marine Unit (EMU)

The Ecological Marine Unit Explorer gives you quick access to critical data of marine environments.

The Ecological Marine Unit Explorer (EMU Explorer) was developed to support better global understanding of the ocean. It includes data from NOAA’s World Ocean Atlasa 3D modeled 50-year average temperature, salinity, dissolved oxygen, nitrate, silicate, phosphate for the entire ocean. Esri, USGS, and a distinguished group of ocean scientist have taken this data and created Ecological Marine Units. EMU’s are a distinct and statistically categorized collection of 37 ecologically significant ocean water types.
