Ecological Marine Unit Explorer was developed to support better global understanding of the ocean. It includes data from NOAA’s World Ocean Atlas; a 3D modeled 50-year average for temperature, salinity, dissolved oxygen, nitrate, silicate and phosphate for the entire ocean. Esri, USGS, and a distinguished group of ocean scientists 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.
